When dynamic tenuring threshold is disabled, or the age census is configured to be computed during evacuation, the first cohort is seeded with the cumulative counts, rather than the current cycle's counts. This is not the default configuration so this is not an urgent issue.

> The purpose of the PR is to add generic JFR events for TaskTerminator to track the attempts and timings that GC threads have tried to terminate GC tasks.
> 
> Today only G1 emits JFR event with name `Termination` from [G1ParEvacuateFollowersClosure](https://github.com/openjdk/jdk/blob/master/src/hotspot/share/gc/g1/g1YoungCollector.cpp#L555-L563), all other garbage collectors don't emit any JFR event for the termination attempt at all. 
> 
> By adding this, it gives performance engineers the visibility to the termination attempts and  termination time when GC threads trying to finish GC tasks, we could build tool to analyze the jfr events to determine if there is potential data structure issue in application code, e.g. very large LinkedList or LinkedBlockingQueue.

> Genshen independently reserves memory to hold evacuations into young and old generations.  We have found that under duress, it is sometimes difficult for mixed evacuations to make progress because the reserves in old are too small and we cannot expand old because young is running so frequently that it does not have the excess memory required to justify expansion of old (and shrinking of young).
> 
> This PR exploits the fact that the reserves in young are often much larger than young requires to carry out its anticipated next GC cycle.  In this case, we can share the young collector reserves with the old generation.  This allows much more effective operation of mixed evacuations when GC is running at or near its full capacity.
> 
> The following spreadsheet snapshots highlight the benefits of this change.  In control with 6G heap size, we perform large numbers of mixed evacuations, but each mixed evacuation has very low productivity (e.g. one region at a time).  This causes excessive delays in reclaiming the garbage from old, which is required to shrink old and expand young.  This is why we see the large number of unproductive GC cycles, many of which degenerate and a few of which upgrade to full GC.  In the experiment with 6G heap size, there are far fewer mixed cycles, but they are each much more productive.  The total number of GC cycles decreases significantly.

By more quickly reclaiming old garbage, we are able to more quickly expand young, which decreases the number of young GC cycles.  This reduces CPU load.  The impact on response times is not as significant as with the 6G heap size.  We see slight improvement at p50-p99.9, with slight degradation at p99.99 through p100.

Subject: RFR: 8358334: C2/Shenandoah: incorrect execution with Unsafe
Message-ID: <unH3_Dq0hn0MMIDtaPXhWtHErOKanNHyRKdUwCkZ0K8=.349734d3-7333-4cca-8a9a-86dc540fdaac@github.com>

When a barrier is expanded, some control is picked as a location for
the barrier. The control input of data nodes that depend on that
control are updated so the nodes are after the expanded barrier unless
the barrier itself depends on some of those nodes.

In this particular failure, a raw memoy `Store` is the input memory to
the barrier. That `Store` has an anti-dependent `Load`. All 3 nodes
(barrier, `Load` and `Store`) are at the same control. The `Store` is
an input to the barrier so it stays before the barrier. The `Load`'s
control is updated to be after the barrier which breaks the
anti-dependency. The bug is that the logic that sorts nodes that need
to be before the barrier and those that can be after ignores
anti-dependencies. The fix simply extends that logic to take them into
account.

I guess swap_card_tables has to be done at safe-point, otherwise we can move this to the place right before swap_card_tables is called in `op_init_mark`

Should we clean only when _generation is young, given we swap card tables when _generation is young?

Suggest moving the reset to a more consolidated natural point rather than piecemeal as done in this solution.

To the point that Xiaolong is making in his other comment, I think we can move this cleaning into the `prepare_gc()` for the young generation which would be called above.

Similarly, see my comment at the other place in degen collection, we'd have the prepare_gc() in the op_reset() clear the rad table along that path.

I think that is the right place to do this resetting as we "prepare" the generation for a future collection at the conclusion of this one.

If we started out with a clean read table, each concurrent gc cleaned the read table after it completed, then if we degenerate outside a cycle, we should find the read table clean already. 

Unless I am missing something, we should be able to assert here that the read table is clean (which the swap already does). Do we need the reset?

It would seem that in the event that we degenerated within a concurrent cycle then we may not have done the reset and that's where we'd need to do an explicit reset further below where we call `op_reset()` which then calls `prepare_gc()` on the generation that was subject to this collection cycle, addressing the point that Xiaolong makes. See my comment in the other file as well.

The patch makes sense.

I ran `make test TEST=all TEST_VM_OPTS=-XX:+UseShenandoahGC` without new failures.

Subject: RFR: 8358821: patch_verified_entry causes problems,
 use nmethod entry barriers instead
Message-ID: <MHl4gp-i7wvWlPIDFe-DgLkTdKsHdN5IMmKfqM62vOU=.77d172b7-3a83-4d6d-9b4e-6b580155088f@github.com>

This PR removes patching of the verified entry point and related code, and replaces it by refactoring the existing nmethod entry barrier.

We used to patch the verified entry point to make sure it was not_entrant.  The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.

The solution I went with reserves one bit of the entry barrier guard value.  This bit must remain set, so I call it a "sticky" bit.  Setting the guard value now is effectively like setting a bitfield, so I needed to add a lock around it.  The alternative would be to change the platform-specific code to do compare-and-swap.

For the lock, I introduced a new NMethodEntryBarrier_lock, whose only purpose is to make the update to the guard value atomic.  For ZGC, I decided to use the existing per-nmethod lock ZNMethod::lock_for_nmethod().  I suspect we could do the same for Shenandoah, if needed for performance.

This change also makes it a bit clearer that  the nmethod entry barrier effectively has two levels.  Level 0 is the outer level or layer controlled by BarrierSetNMethod::nmethod_stub_entry_barrier(), and the inner layer controlled by BarrierSetNMethod::nmethod_entry_barrier().  This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

I appreciate this PR. I like using the nmethod entry barrier and getting rid of not-entrant patching.
I have some change requests. In addition, we can get rid of much more code. I've put my proposal in a Commit: https://github.com/TheRealMDoerr/jdk/commit/4aed569dc353c254a2f4de2d387208a0a1323990
Please take a look!

src/hotspot/share/gc/shared/barrierSetNMethod.cpp line 246:

> 244:   ConditionalMutexLocker ml(NMethodEntryBarrier_lock, !NMethodEntryBarrier_lock->owned_by_self(), Mutex::_no_safepoint_check_flag);
> 245:   int value = guard_value(nm) | not_entrant;
> 246:   set_guard_value(nm, value);

Same here.

src/hotspot/share/gc/shenandoah/shenandoahCodeRoots.cpp line 153:

> 151:         // Code cache unloading needs to know about on-stack nmethods. Arm the nmethods to get
> 152:         // mark_as_maybe_on_stack() callbacks when they are used again.
> 153:         _bs->arm(nm);

This breaks the Shenandoah build. `arm` is private.

src/hotspot/share/gc/z/zBarrierSetNMethod.cpp line 116:

> 114:     value |= not_entrant;
> 115:   }
> 116:   set_guard_value(nm, value);

We can avoid redundant patching since we have the lock: Only update if the value is not already there. This happens quite often.

Thanks @TheRealMDoer for the suggestions, I incorporated all of them, however for shenandoahCodeRoots.cpp I decided to make arm() public, so the caller code doesn't need to know about the magic value 0.

> Genshen independently reserves memory to hold evacuations into young and old generations.  We have found that under duress, it is sometimes difficult for mixed evacuations to make progress because the reserves in old are too small and we cannot expand old because young is running so frequently that it does not have the excess memory required to justify expansion of old (and shrinking of young).
> 
> This PR exploits the fact that the reserves in young are often much larger than young requires to carry out its anticipated next GC cycle.  In this case, we can share the young collector reserves with the old generation.  This allows much more effective operation of mixed evacuations when GC is running at or near its full capacity.
> 
> The following spreadsheet snapshots highlight the benefits of this change.  In control with 6G heap size, we perform large numbers of mixed evacuations, but each mixed evacuation has very low productivity (e.g. one region at a time).  This causes excessive delays in reclaiming the garbage from old, which is required to shrink old and expand young.  This is why we see the large number of unproductive GC cycles, many of which degenerate and a few of which upgrade to full GC.  In the experiment with 6G heap size, there are far fewer mixed cycles, but they are each much more productive.  The total number of GC cycles decreases significantly.

> With 7G heap size, the benefits of this PR manifest as a decrease in mixed evacuations, which also allows us to decrease total GC cycles.  By more quickly reclaiming old garbage, we are able to more quickly expand young, which decreases the number of young GC cycles.  This reduces CPU load.  The impact on response times is not as significant as with the 6G heap size.  We see slight improvement at p50-p99.9, with slight degradation at p99.99 through p100.

@pengxiaolong - We don't want to clean the read table during init-mark because that's a safepoint. We can safely clean the read table concurrently because only the GC thread has access to it.

@ysramakrishna - The refactoring you suggest is not so simple, alas. We have to be very careful about the ordering of cleaning the `read` table, resetting the mark bitmap and swapping the card tables. Genshen does not clean the `read` table at the end of a concurrent cycle (we _could_ do this, but we'd still need to do the same in a degenerated cycle). The complexity comes from swapping the card tables in a concurrent cycle. We must not let a subsequent degenerated cycle swap them a second time. The degenerated cycle can only clean the `read` table if there was no active concurrent cycle (lest it throw away critical remembered set data). 

However, the degenerated cycle must also clear the mark bitmaps if the concurrent cycle degenerated during the root scan (the degenerated cycle will rescan the roots). Of course, we cannot clear the mark bitmaps if the concurrent cycle degenerated during the mark phase. So, for the degenerated cycle, clearing the mark bitmaps and cleaning the read table need to happen in two different cases and it doesn't work if they're combined into the same method (and I don't think adding a method parameter to sometimes clear the mark bitmap and sometimes the read table will make the code any easier to understand).

We can remove `GCCause::_no_cause_specified` and need to add a case for `_shenandoah_humongous_allocation_failure` in `GCCause::to_string`. We are also missing `_shenandoah_humongous_allocation_failure` in the `SA` analog.

Just reordered this case to match enum's declaration order.

Shenandoah does not use this method. Nobody else needs to know about this Shenandoah specific value.

Shenandoah parts look good, but we should avoid changing shared code unnecessarily.

Changes requested by shade (Reviewer).

Code history shows this enum was there since the beginning of OpenJDK. So it is better to leave it alone. It is also less confusing to have only Shenandoah-specific changes in RFE that starts with "Shenandoah: ..."

This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

LGTM, now. I think `is_sigill_not_entrant` should also be removed completely: https://github.com/TheRealMDoerr/jdk/commit/f61f54a40ad0b952ba8c0a668675b3f315f83a95
I've run tests on some platforms, but will run on more.
@offamitkumar, @RealFYang, @bulasevich: You may also want to check your platforms.
@fisk: You may want to take a look at the nmethod entry barrier changes.

> This change also makes it a bit clearer that  the nmethod entry barrier effectively has two levels.  Level 0 is the outer level or layer controlled by BarrierSetNMethod::nmethod_stub_entry_barrier(), and the inner layer controlled by BarrierSetNMethod::nmethod_entry_barrier().  This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

Reviewed -- would be good to go from my standpoint after separating into a separate ticket as suggested by Aleksey the collapse of `no_cause_specified` into its putative synonym `_no_gc`.

Approving in advance, subject to that change, and re-review by Aleksey.

I agree that "no cause specified" and "no gc" almost sound like synonyms, and any uses of one could be replaced with the other. However, with @shipilev , I agree that may be you split the changes to this kind of shared code into a separate ticket, in keeping with hotspot dev practices.

8253714: [cgroups v2] Soft memory limit incorrectly using memory.high

The early implementation of cgroups v2 support was done with
crun 0.8 and it contained a bug which set memory.high over
memory.low when --memory-reservation was being used as a CLI
option.

This bug has been fixed in later crun versions, starting with
crun 0.11. Use memory.low in OpenJDK as well.

Account for interface files for swap and memory being reported independently.
The cgroup v1-like value is now reported by adding the memory.max value to
the memory.swap.max value, and memory.current and memory.swap.current
respectively.

8252957: Wrong comment in CgroupV1Subsystem::cpu_quota

The comment is wrong. The 'us' in 'cpu.cfs_quota_us' stands for
microseconds, which is read verbatim. Similarly for cgroups v2
all units in 'cpu.max' are in microseconds.

The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.

This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

Tests look good on our side. I'm only a bit concerned that the lock may become a bottleneck when many Java threads need to patch all nmethods. Especially with ZGC which does that more often. I think we should check performance.

The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.

This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

Thanks for doing this! I have been wanting something like this for a while too and it looks great. I have some comments though...

src/hotspot/share/gc/z/zBarrierSetNMethod.cpp line 109:

> 107: }
> 108: 
> 109: void ZBarrierSetNMethod::arm_with(nmethod* nm, int value) {

I don't usually comment on names, but could we call this guard_with instead? We tried to stop saying "arm" about things used also for disarming and we have (hopefully) been consistent about calling that "guard" instead.

src/hotspot/share/gc/z/zBarrierSetNMethod.cpp line 114:

> 112:   // Preserve the sticky bit
> 113:   if (is_not_entrant(nm)) {
> 114:     value |= not_entrant;

Is it possible to have a race where another thread sets an nmethod to not entrant and the thread calling this making the nmethod entry barrier not entrant?

If this was called to disarm a method and then enter it, it seems a bit sneaky in that case that we pass the nmethod entry barrier even though we under the lock see that it is not entrant. Probably okay but still feels like it might be more robust if the thread setting an nmethod to not entrant is always the one that arms the nmethod entry barrier.

 ShenandoahGC

Hello Roland,

Thanks much for an amazingly fast fix!

Are there any chances to get it backported to jdk 17 and 21?

Our product (Apache Ignite) heavily relies on off-heap memory operations 
via Unsafe.  I already applied the work around in our code but still not 
100% sure that problem wouldn't hit in some other place.

I can drive the backport if you would help with steps which needed the 
JBS user account.

WBR,

I'm OK with the shared GC changes if you change the title of JBS issue or split it out the shared parts into a separate issue.

The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.

Level 0 is the outer level or layer controlled by BarrierSetNMethod::nmethod_stub_entry_barrier(), and the inner layer controlled by BarrierSetNMethod::nmethod_entry_barrier().  This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

JBS Issue : [JDK-8349077](https://bugs.openjdk.org/browse/JDK-8349077)

we found the method names `update_all` of the class `GenerationCounters` and its subclasses are not so good. It is better to rename it to something like `update_capacity` (such as `ZGenerationCounters::update_capacity`).

@offamitkumar: The problem is probably the initialization to -1: [`z_cfi(Z_R0_scratch, /* to be patched */ -1);`.](https://github.com/openjdk/jdk/blob/9d060574e5dbd13e634f00d749d0108ceff1fae8/src/hotspot/cpu/s390/gc/shared/barrierSetAssembler_s390.cpp#L183)
Should be 0.

Seems like arm32 has the same issue: https://github.com/openjdk/jdk/blob/9d060574e5dbd13e634f00d749d0108ceff1fae8/src/hotspot/cpu/arm/gc/shared/barrierSetAssembler_arm.cpp#L199
The init value shouldn't have the sticky bit set.

JBS Issue : [JDK-8349077](https://bugs.openjdk.org/browse/JDK-8349077)

we found the method names update_all of the class GenerationCounters and its subclasses are not so good. It is better to rename it to something like update_capacity (such as ZGenerationCounters::update_capacity).



Update_capacity exists, since update_all updates the size and used , I found update_memory_state as a better name for this method.

Hi Sergey,

I intend to backport it to 25, 21 and 17.

So the bug could affect end users of Apache Ignite? That's useful to
know and I'll use that to motivate the backports.

I believe the ticket was only about this method, which handles only capacity.


void GenerationCounters::update_all(size_t curr_capacity) {
  _current_size->set_value(curr_capacity);

However, in the patch, this method is renamed as well. Not sure if this is intentional.


void HSpaceCounters::update_all(size_t capacity, size_t used) {
  update_capacity(capacity);
  update_used(used);
}

Since the base is before the branch off, could you please merge master before integration and see if GHA still passes? This also helps us testing libgraal compilation.

Thanks, we want to minimize the time at safepoint, I understand this part. My question was about swap_card_tables, I we don't have to do it at safepoint, we could move swap_card_tables out of the init-mark safepoint and move to close to mark_read_table_as_clean to make the code slight earlier to understand. @ysramakrishna also suggested this, I saw your attempt and rollback, thanks for the explanations.

It looks good to me.

Thanks for the explanation; let me digest this and re-review with this background. I'll update before EOD.

> @ysramakrishna - The refactoring you suggest is not so simple, alas. We have to be very careful about the ordering of cleaning the `read` table, resetting the mark bitmap and swapping the card tables. Genshen does not clean the `read` table at the end of a concurrent cycle (we _could_ do this, but we'd still need to do the same in a degenerated cycle). The complexity comes from swapping the card tables in a concurrent cycle. We must not let a subsequent degenerated cycle swap them a second time. The degenerated cycle can only clean the `read` table if there was no active concurrent cycle (lest it throw away critical remembered set data).
> 
> However, the degenerated cycle must also clear the mark bitmaps if the concurrent cycle degenerated during the root scan (the degenerated cycle will rescan the roots). Of course, we cannot clear the mark bitmaps if the concurrent cycle degenerated during the mark phase. So, for the degenerated cycle, clearing the mark bitmaps and cleaning the read table need to happen in two different cases and it doesn't work if they're combined into the same method (and I don't think adding a method parameter to sometimes clear the mark bitmap and sometimes the read table will make the code any easier to understand).

We have to be very careful about the ordering of cleaning the `read` table, resetting the mark bitmap and swapping the card tables. Genshen does not clean the `read` table at the end of a concurrent cycle (we _could_ do this, but we'd still need to do the same in a degenerated cycle). The complexity comes from swapping the card tables in a concurrent cycle. We must not let a subsequent degenerated cycle swap them a second time. The degenerated cycle can only clean the `read` table if there was no active concurrent cycle (lest it throw away critical remembered set data).

Of course, we cannot clear the mark bitmaps if the concurrent cycle degenerated during the mark phase. So, for the degenerated cycle, clearing the mark bitmaps and cleaning the read table need to happen in two different cases and it doesn't work if they're combined into the same method (and I don't think adding a method parameter to sometimes clear the mark bitmap and sometimes the read table will make the code any easier to understand).

My question was about swap_card_tables, I we don't have to do it at safepoint, we could move swap_card_tables out of the init-mark safepoint and move to close to mark_read_table_as_clean to make the code slight earlier to understand. @ysramakrishna also suggested this, I saw your attempt and rollback, thanks for the explanations.

@pengxiaolong - I think we _could_ swap card table pointers with a thread local handshake, but if we don't remove `init-mark` entirely, it would just mean stopping all the threads twice. I'm inclined to leave it on the safepoint for now.

Good suggestion.  Fixed.

Probably okay but still feels like it might be more robust if the thread setting an nmethod to not entrant is always the one that arms the nmethod entry barrier.

If I understand your concern correctly, there is no race.  The only caller of BarrierSetNMethod::make_not_entrant() is nmethod::make_not_entrant(), and it is done inside a NMethodState_lock critical section.  After a call to nmethod::make_not_entrant(), the nmethod entry barrier is armed and stays that way.
And by design, a disarm only disarms at the inner nmethod_entry_barrier level, not the outer nmethod_stub_entry_barrier level.

For ZGC I am using a per-nmethod lock:
  ZLocker<ZReentrantLock> locker(ZNMethod::lock_for_nmethod(nm));

I don't know what benchmarks to run to check the performance for functions like Deoptimization::deoptimize_all_marked, so I welcome any help with this.

One possible optimization that might help is skipping the lock if the make_not_entrant call is done during a safepoint.

@earthling-amzn : 

> Genshen does not clean the read table at the end of a concurrent cycle (we could do this, but we'd still need to do the same in a degenerated cycle).

Yes, and I am suggesting we do that to clean up and consolidate the cleaning along multiple paths into the same method that is invoked at an identical point in the Collector's state machine, irrespective of whether we arrived at that state via a concurrent collection or a degeneration.

> The complexity comes from swapping the card tables in a concurrent cycle. We must not let a subsequent degenerated cycle swap them a second time. The degenerated cycle can only clean the read table if there was no active concurrent cycle (lest it throw away critical remembered set data).

The swapping must happen at the start of the marking cycle. In similar fashion, the state of the Collector's state machine should indicate if the swap has already been done in this cycle or not. The specifics of wheher the swap was done by a degenerate or concurrent collection should then not matter?

> However, the degenerated cycle must also clear the mark bitmaps if the concurrent cycle degenerated during the root scan (the degenerated cycle will rescan the roots). Of course, we cannot clear the mark bitmaps if the concurrent cycle degenerated during the mark phase. So, for the degenerated cycle, clearing the mark bitmaps and cleaning the read table need to happen in two different cases and it doesn't work if they're combined into the same method (and I don't think adding a method parameter to sometimes clear the mark bitmap and sometimes the read table will make the code any easier to understand).

That's OK, they can be in two different methods, with the clearing of the marking bitmap done in one case and not in the other based on when the degeeration occurred. I think may be we don't have sufficiently refined Collector state machine at the moment which may be part of the problem here.

That having been said, I can understand that:

> The refactoring you suggest is not so simple, alas. 

In particular, if our eventual future plan is to do away with degeneration as we know it today, then the refactoring to achieve the clean up I suggest may be moot.

With that in mind, I am going to approve the changes in their current form as they look right if somewhat difficult to maintain and prove the correctness of. (The more refined state machine approach would likely make it easier, but will be moot once degeneration is eliminated in the future.)

`ltr` instruction stands for "load and test" (32 bit). Initially we were loading the value from `Z_RET` to `Z_R0_scratch` and then it will be compared against 0. But in this case there is no requirement of loading the value in Z_R0, as it's not being used further. So we can load the value again in `Z_RET` and the compare it against 0. There is nothing wrong in previous solution, it's just killing Z_R0 for nothing.

Oops, I was tripped up trying to be clever.  Yes, I'm fine with using 0.  I'll fix it.

> This PR removes patching of the verified entry point and related code, and replaces it by refactoring the existing nmethod entry barrier.
> 
> We used to patch the verified entry point to make sure it was not_entrant.  The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.
> 
> The solution I went with reserves one bit of the entry barrier guard value.  This bit must remain set, so I call it a "sticky" bit.  Setting the guard value now is effectively like setting a bitfield, so I needed to add a lock around it.  The alternative would be to change the platform-specific code to do compare-and-swap.
> 
> For the lock, I introduced a new NMethodEntryBarrier_lock, whose only purpose is to make the update to the guard value atomic.  For ZGC, I decided to use the existing per-nmethod lock ZNMethod::lock_for_nmethod().  I suspect we could do the same for Shenandoah, if needed for performance.
> 
> This change also makes it a bit clearer that  the nmethod entry barrier effectively has two levels.  Level 0 is the outer level or layer controlled by BarrierSetNMethod::nmethod_stub_entry_barrier(), and the inner layer controlled by BarrierSetNMethod::nmethod_entry_barrier().  This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

Of course, we cannot clear the mark bitmaps if the concurrent cycle degenerated during the mark phase. So, for the degenerated cycle, clearing the mark bitmaps and cleaning the read table need to happen in two different cases and it doesn't work if they're combined into the same method (and I don't think adding a method parameter to sometimes clear the mark bitmap and sometimes the read table will make the code any easier to understand).

Thanks for the review @ysramakrishna . The plan is to get rid of degenerated cycles, but if the plan changes we certainly need to invest in a stronger state machine for the GC here.

The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.

This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

Or maybe even better just entirely delete `ZGenerationCounters` and replace its usages with `GenerationCounters`.

The only caller of BarrierSetNMethod::make_not_entrant() is nmethod::make_not_entrant(), and it is done inside a NMethodState_lock critical section.  After a call to nmethod::make_not_entrant(), the nmethod entry barrier is armed and stays that way.
> And by design, a disarm only disarms at the inner nmethod_entry_barrier level, not the outer nmethod_stub_entry_barrier level.

My concern is that while thread 1 calls nmethod::make_not_entrant(), thread 2 racingly performs nmethod entry barrier; it makes the is_not_entrant check before it gets updated, but then it gets updated as the per nmethod lock is taken. The GC code "disarms" the GC barrier but in doing so finds that "oh this should be not entrant", but that's sort of not reflected as thread 2 will then proceed with entering the nmethod it just armed as not entrant in the nmethod entry barrier code.
Does that make sense?

Subject: RFR: 8359947: GenShen: use smaller TLABs by default
Message-ID: <1072g2RnSN--eWgcAOHvElE0OI03fCdGJNGIgFNDnOQ=.21aca821-59c9-47b5-b1a2-6214f85dd5d3@github.com>

We have found with certain workloads that the initial and maximum tlab sizes result in very high latencies for the first few invocations of particular methods for certain threads.  The root cause is that TLABs are too large.  This is causing allocatable memory to be depleted too quickly.  When large numbers of threads are trying to startup at the same time, some of the threads end up with no TLABs or very small TLABs and their efforts run hundreds of times slower than the threads that were able to grab very large TLABs.

This PR reduces the maximum TLAB size and adjusts the initial TLAB size in order to reduce the impact of this problem.

This PR also changes the value of TLABAllocationWeight from 90 to 35 when we are running in generational mode.  35 is the default value used for G1 GC, which is also generational.  The default value of 90 was established years ago for non-generational Shenandoah because it tends to have less frequent GC cycles than generational collectors.

We have exercised this PR with three different workloads, which we identify as small, medium, and huge.  We have also exercised in two different configurations: with and without 30s warmup before latency measurements are taken.  Finally, we have applied this PR to both tip and to a development branch identified as adaptive-evac-with-surge.

The initial motivation for this PR was identified during testing of the adaptive-evac-with-surge branch.  That branch runs more aggressive GCs (larger evacuation workloads, with delayed (slightly more risky) triggers.  The objectives of this branch are to make GCs more efficient and to reduce CPU consumption.

We report 6 results for each experiment.  We sort these according to P100 latencies, and average results from the bottom four (best performing) samples, tossing out the two high outliers from the averages.  Workload results are subject to noise from elastic computing and operating system interference.

The benefits of this PR are most notable with the p99.999 and p100 small configuration of adaptive-evac-with-surge and the huge configuration of tip:

Note also the degradation in p50 and other lower percentile latencies.  The effect of this PR is to require each mutator thread to make more frequent allocation of smaller TLABs.  This results in higher contention for Shenandoah's global heap lock.  A separate development effort is refactoring the slow allocation path to use a single CAS for the large majority of TLAB allocations rather than the current mechanism, which requires each TLAB allocation to contend for exclusive access to the global heap lock, then hold the global heap lock during the search for memory to be allocated.  We expect this other mechanism will improve all latencies, and should reduce or eliminate the performance regressions introduced at certain percentiles by this PR.

For full context, other performance comparisons are also provided here.  In the following reports, it is usually the case that the affect of this PR is to reduce the total number of GCs and to reduce the CPU utilization.  Depending on the experiment, low percentile or high percentile response times improve.  We attribute these differences to contention for global heap lock.  We observe also that sometimes warming up an experiment for 30 seconds before beginning to measure latency has a similar effect to improving the initial TLAB size,  as the pre-existing shared heuristics for adaptive TLAB sizing seem to converge fairly quickly on improved behavior, at least for this workload which is fairly consistent.  A more variable workload may struggle more to find the optimal TLAB size.  For such workloads, having smaller default TLAB sizes seems to reduce the likelihood of occasional serious performance degradation.

While both versions of code are clearly overwhelmed for this Medium workload, it is interesting to observe that the PR produces two results that are much better than all six of the control runs.  Better performance and more meaningful comparisons are provided by the adaptive-old-evac-with-surge experiments, shown below.

The small workload is represented by the following execution script.  Note that we override the default region size in order to avoid out-of-memory-during-evacuation failures that were occurring in the default configuration due to a large number of objects of approximate size 781 KB.

What's the rationale for using a fraction of the region size as a possible maximum TLAB size? Region size seems unrelated to thread object allocation demand.

Region size is generally proportional to total heap size.  If we have larger heap sizes, we have more abundant memory, and can generally afford to be "slightly" more generous in apportionment of memory between threads.  But we do this within limits.

The initial TLAB size is never made smaller than 32KB and the max TLAB size is never made larger than 256KB.

Looks good to me! 
Smaller tlab will result more contention on heap lock in the slow path to allocate tlab, the task I am working on to use CAS may help to mitigate.

Doesn't the old code have the same limitation? If thread 1 patches the entry point after thread 2 has executed the first instruction, thread 2 will be inside the nmethod if GC has disarmed the nmethod entry barrier.

Well, yeah sort of. And hence the comment that it's probably fine in terms of correctness. They were also a bit more independent systems then though. Just thought that if we now take the step to merge compiler and GC entry trap mechanisms into the nmethod entry barrier, that we could seemingly also make it a bit less slippery here and establish some sort of invariant that if we while holding the lock protecting the entry barrier find that the nmethod entry barrier is not entrant, for whatever reason, we should not enter it. Would make it easier to understand the code I suspect. What do you think?

I think making it less slippery in one place but still leaving other races gives a false sense of security and makes the code harder to understand.  Arming the barrier is not guaranteed to be visible until there is a safepoint.  Note that AArch64 and RISCV only call increment_patching_epoch() when the guard value is set to the disarmed value, so there is no invalidation of the CPU pipeline or instruction buffer (cross modification fence) when arming.

Shenandoah captures a preliminary top-at-mark-start (TAMS) concurrently. Once concurrent marking has begun, any object beneath TAMS requires a barrier when accessed. The implementation of `ShenandoahHeap::requires_barrier` does not distinguish between _old_ and _young_ marking. This could lead to a race between freezing the stack and capturing TAMS:

1. Collector is marking old
2. Allocate stack chunk in young
3. Barrier is not needed, begin fast freeze path
4. Collector concurrently updates TAMS (young marking will start once init-mark safepoint is reached)
5. ShenandoahHeap now thinks the barrier is needed (because TAMS changed, and we are marking old)
6. Fast freeze asserts out

This fix has the generational mode check the appropriate generation and its marking state. It also enforces barriers for stackChunks in the old generation (for card marking).

Just so I understand (and maybe this deserves a clarifying comment to help others understand):
  The barrier we are concerned about here is SATB.  If obj is above TAMS, there's no need to enforce a SATB barrier.  Any reference residing above TAMS which is overwritten will have been marked already, or is about to be marked.  Either the value is already "presumed marked" because it also resides above TAMS, or its value was assigned from a root (in which case root scanning marked it), or it was copied from a pre-existing object (in which case it will be marked by scanning of that pre-existing object or by SATB).

Yes, concerned about SATB here.

The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.

Level 0 is the outer level or layer controlled by BarrierSetNMethod::nmethod_stub_entry_barrier(), and the inner layer controlled by BarrierSetNMethod::nmethod_entry_barrier().  This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

Ah, right. So, ZGC should be fine.

I have tried some SPEC benchmarks with G1 on PPC64, but couldn't observe a regression. (If there is one, it was below noise.)

I guess the most critical scenario is when many Java threads need to disarm a large number of nmethod entry barriers. That doesn't happen at a safepoint. Not sure if other scenarios are worth optimizing by this idea.

I guess this PR is ok as it is. Maybe other reviewers have more comments.

Just thought that if we now take the step to merge compiler and GC entry trap mechanisms into the nmethod entry barrier, that we could seemingly also make it a bit less slippery here and establish some sort of invariant that if we while holding the lock protecting the entry barrier find that the nmethod entry barrier is not entrant, for whatever reason, we should not enter it. Would make it easier to understand the code I suspect. What do you think?

Arming the barrier is not guaranteed to be visible until there is a safepoint.  Note that AArch64 and RISCV only call increment_patching_epoch() when the guard value is set to the disarmed value, so there is no invalidation of the CPU pipeline or instruction buffer (cross modification fence) when arming.

Okay. I would have preferred to not enter the nmethod when we evaluate the guard bits under the lock that protects it and see that it's supposed to be not entrant. But I won't argue for it further if you prefer not to change that. Other than that, I think this looks good.

I think it's OK if there is a race to have a point of no return, and if one thread gets there first, it wins, and we don't need to check again.  It's tempting to want to do an extra check when we disarm under the lock, but then it would need a comment explaining why we do it, even though the make_not_entrant could come in right after and we would miss it.  And we have already done the work of healing the oops by this point.  Finally, I like the encapsulation that only nmethod_stub_entry_barrier needs to know about not_entrant, and nmethod_entry_barrier doesn't need to know.

The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.

Setting the guard value now is effectively like setting a bitfield, so I needed to add a lock around it.  The alternative would be to change the platform-specific code to do compare-and-swap.

Level 0 is the outer level or layer controlled by BarrierSetNMethod::nmethod_stub_entry_barrier(), and the inner layer controlled by BarrierSetNMethod::nmethod_entry_barrier().  This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

Just FYI: My local tier1-3 test on linux-riscv64 is good. And I didn't witness an obvious change on specjbb performance with g1gc.

>> This PR removes patching of the verified entry point and related code, and replaces it by refactoring the existing nmethod entry barrier.
>> 
>> We used to patch the verified entry point to make sure it was not_entrant.  The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.
>> 
>> The solution I went with reserves one bit of the entry barrier guard value.  This bit must remain set, so I call it a "sticky" bit.  Setting the guard value now is effectively like setting a bitfield, so I needed to add a lock around it.  The alternative would be to change the platform-specific code to do compare-and-swap.
>> 
>> For the lock, I introduced a new NMethodEntryBarrier_lock, whose only purpose is to make the update to the guard value atomic.  For ZGC, I decided to use the existing per-nmethod lock ZNMethod::lock_for_nmethod().  I suspect we could do the same for Shenandoah, if needed for performance.
>> 
>> This change also makes it a bit clearer that  the nmethod entry barrier effectively has two levels.  Level 0 is the outer level or layer controlled by BarrierSetNMethod::nmethod_stub_entry_barrier(), and the inner layer controlled by BarrierSetNMethod::nmethod_entry_barrier().  This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

It's tempting to want to do an extra check when we disarm under the lock, but then it would need a comment explaining why we do it, even though the make_not_entrant could come in right after and we would miss it.  And we have already done the work of healing the oops by this point.  Finally, I like the encapsulation that only nmethod_stub_entry_barrier needs to know about not_entrant, and nmethod_entry_barrier doesn't need to know. 

Fair enough!

Generational shenandoah currently doesn't pick up the changes of managed flag `SoftMaxHeapSize` when the app is running. This is because the value of `_soft_max_capacity` in `shenandoahGeneration` is never changed.

This change delegates the soft max heap size in `shenandoahGeneration` to `ShenandoahGenerationalHeap::heap()->soft_max_capacity()`, which does pick up the flag value changes.

Also, found `ShenandoahHeap:: initialize` uses `_num_regions * reg_size_bytes` rather than user input flag value. Updated to using actual flag value.

Some nits.

Can we remove these, or at least make them `log_develop_debug`?

Can we add a comment here saying that we need this message for the `TestDynamicSoftMaxHeapSize`? Also, this property will be read far more often than it will be written. Can we put the log message in the place where the value changes?

src/hotspot/share/gc/shenandoah/shenandoahGeneration.hpp line 129:

Can we take out the `_soft_max_capacity` member from `ShenandoahGeneration` now?

Let's keep the includes alphabetized.

I don't think we need parentheses around `new OutputAnalyzer(...)`.

The generational mode will quietly ignore other heuristics: https://bugs.openjdk.org/browse/JDK-8342640

Will add a comment. 

There is actually an existing info level log for soft_max_heap change: [code](https://github.com/openjdk/jdk/blob/6df0f5e390ecf874c1eca7284c51efa65ce23737/src/hotspot/share/gc/shenandoah/shenandoahHeap.cpp#L865-L868). (Side note: we can't simply validate this info log line in the test, since gen shen didn't use the value initially)

Yes. Good catch. Removed

These two aren't used actually. Removed.

> The purpose of the PR is to add generic JFR events for TaskTerminator to track the attempts and timings that GC threads have tried to terminate GC tasks.
> 
> Today only G1 emits JFR event with name `Termination` from [G1ParEvacuateFollowersClosure](https://github.com/openjdk/jdk/blob/master/src/hotspot/share/gc/g1/g1YoungCollector.cpp#L555-L563), all other garbage collectors don't emit any JFR event for the termination attempt at all. 
> 
> By adding this, it gives performance engineers the visibility to the termination attempts and  termination time when GC threads trying to finish GC tasks, we could build tool to analyze the jfr events to determine if there is potential data structure issue in application code, e.g. very large LinkedList or LinkedBlockingQueue.
> 
> For the test, I have manually tested different GCs with Flight Recording enabled and verified the events:

The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.

This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

@fisk: The initial value doesn't match our initialization in the nmethod entry barrier code were we use 0. That causes all new nmethods to run through the barrier code when they are called for the first time. I think that is unnecessary and it slows down the startup a bit. All oops should already be correct after the nmethod got installed. And for ZGC, we call `nmethod_patch_barriers` in `ZNMethod::register_nmethod`. So, I don't see any need to execute the barrier code. We could change the initialization to use `_current_phase`. Do you agree? Should I file a new JBS issue?

In other words, I think `disarm(nm);` is missing for some GCs. ZGC has it in `ZNMethod::register_nmethod`.

That causes all new nmethods to run through the barrier code when they are called for the first time. I think that is unnecessary and it slows down the startup a bit. All oops should already be correct after the nmethod got installed. And for ZGC, we call `nmethod_patch_barriers` in `ZNMethod::register_nmethod`. So, I don't see any need to execute the barrier code. We could change the initialization to use `_current_phase`. Do you agree? Should I file a new JBS issue?

I've filed https://bugs.openjdk.org/browse/JDK-8360540. We don't need to discuss it here.

The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.

Setting the guard value now is effectively like setting a bitfield, so I needed to add a lock around it.  The alternative would be to change the platform-specific code to do compare-and-swap.

Level 0 is the outer level or layer controlled by BarrierSetNMethod::nmethod_stub_entry_barrier(), and the inner layer controlled by BarrierSetNMethod::nmethod_entry_barrier().  This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

> We have found with certain workloads that the initial and maximum tlab sizes result in very high latencies for the first few invocations of particular methods for certain threads.  The root cause is that TLABs are too large.  This is causing allocatable memory to be depleted too quickly.  When large numbers of threads are trying to startup at the same time, some of the threads end up with no TLABs or very small TLABs and their efforts run hundreds of times slower than the threads that were able to grab very large TLABs.

The default value of 90 was established years ago for non-generational Shenandoah because it tends to have less frequent GC cycles than generational collectors.

 - remove redundant doc comments
 - fix copy paste errors in riscv
 - fix copy paste errors in s390
 - fix copy paste errors in zero
 - fix errors in x86 stub entry declarations
 - fix various copy paste errors
 - fix whitespace error
 - update other arches to use global ids
 - use global ids everywhere -- aarch64 only
 - support global blob/stub/entry ids

Hi, please consider the following changes:

There are many classes inherited from the `HandshakeClosure` class, but they do not follow the same naming convention. In this PR we address this issue, all names are normalized in the following way:

`XXXDummyClassNameClosure -> XXXDummyClassNameHandshakeClosure`

or

`XXXDummyClassNameHandshake -> XXXDummyClassNameHandshakeClosure`

or

`XXXStrangeClassName -> SomewhatSimilarNameHandshakeClosure`

Tested in GHA and tiers 1 - 3.

This PR fixes the test failures seen in many JTreg tests related to Shenandoah GC (`test/hotspot/jtreg/gc/shenandoah/`) with UseAPX. The issues were root caused to: 

1. Higher band registers are not saved and restored in Shenandoah load_reference_barrier. 
2. Pusha/Popa implementation using push2p/pop2p 

Both the issues are fixed in this PR.

I found a couple of places to realign the parameters, but otherwise this looks good.  I like the new naming conventions.  We have a lot of handshakes now!
Were you able to build shenandoah (not built by default, need to add --enable-jvm-feature-shenandoahgc to configure)?

src/hotspot/share/prims/jvmtiEnvBase.hpp line 629:

Can you realign these parameters?

src/hotspot/share/prims/jvmtiEnvBase.hpp line 650:

realign parameters.

> 760:                              jthread thread, jint max_frame_count)

Also realign parameters.

src/hotspot/share/prims/jvmtiEnvBase.hpp line 798:

> 796: public:

> 798:                           jmethodID* method_ptr, jlocation* location_ptr)

Also realign parameters.

I do not support this unification over JVMTI files. This make `HandshakeClosure` class names too long.
The JVMTI has a consistent local naming convention to have the suffix `Closure` at the end instead of `HandshakeClosure`. And it is fine because normally there are no other kind of closures in JVMTI code.

I was going to let it bake in jdk26 for a while before deciding.  It seems a bit risky to me.  I am leaning towards not backporting it to Oracle JDK.  For OpenJDK 25, it might make more sense to do a PPC-specific fix like adding a NOP at the verified entry point.  What do you think?

I'm not convinced that only PPC64 is affected. [JDK-8258229](https://bugs.openjdk.org/browse/JDK-8258229) looks wrong for all platforms except x86 and may be even problematic on that platform as you had mentioned (due to NMethodState_lock). Would it make sense to backout JDK-8258229 in jdk25 and live with it? That issue doesn't look so critical.
Or maybe guard the code with #ifdef x86?

@adinn I got one test failure on s390: `test/hotspot/jtreg/runtime/ErrorHandling/MachCodeFramesInErrorFile.java`

Yes, the code compiles fine with --enable-jvm-feature-shenandoahgc added.

@sspitsyn How about this: instead of xxxHandshakeClosure put xxxHSClosure? HS would stand for Handshake, but the length will increase by only 2 symbols.

Hi @vamsi-parasa ,

PUSHA / POPA assembler is agnostic to the use of hardcoded registers in calling context, e.g. in following line of code
https://github.com/openjdk/jdk/blob/master/src/hotspot/cpu/x86/gc/shenandoah/shenandoahBarrierSetAssembler_x86.cpp#L495

If dst and tmp1 are RAX then we endup currpting it since RAX is used as a scratch register for stack alignment, and in case RAX holds an oop pointer then we may see random crashes. Such idioms are limited to GC barreirs currently, and we have recently fixed one such issue in https://github.com/openjdk/jdk/pull/25351

While the instruction sequence of PUSHA/ POPA with PPX hints is correct, Do you think for the time being we should limit the scope of this fix to save_machine_state and restor_machine_state routines rather than making generic fix in pusha/popa ?

I have tried it and it's working.

@offamitkumar Thanks for testing. I'm looking into the issue and will get back to you.

@TheRealMDoerr @offamitkumar @RealFYang Would you be able to check this on ppc/riscv to ensure it builds (cross-compile is ok) and passes (at least) tier1?

Thanks for whatever help you can provide.

@vnkozlov My fastdebug build has passed the following test suites on Linux/aarch64 and Linux/x86:

  tier1
  jtreg/test/hotspot/jtreg/runtime
  jtreg/test/hotspot/jtreg/compiler

Could you review the PR and maybe run it through internal testing?

@offamitkumar I'm somewhat puzzled by your test result. It indicates that the hserr file generated during the test contained a stack trace for the crash point listing two compiled Java method frames but that only one [MachCode][/MachCode] listing was generated into the file. That seems a bit odd since the other arches seem to generate at least 2 listings.

I am seeing if I can reproduce the error on a borrowed s390 machine.

One thing you might perhaps be able to try meanwhile to check what is going on is to run the test again with env var DEBUG set

    $ DEBUG=debug make test TEST=TEST=test/hotspot/jtreg/runtime/ErrorHandling/MachCodeFramesInErrorFile.java

This ought to force the contents of the hserr file to be written to the System.err which means they will be visible in file `build/linux-s390x-server-fastdebug/test-support/jtreg_test_hotspot_jtreg_runtime_ErrorHandling_MachCodeFramesInErrorFile_java/runtime/ErrorHandling/MachCodeFramesInErrorFile.jtr`

The output may get truncated but even then it still might give us some idea of what is going wrong.

@offamitkumar I managed to run the test on an s390x build and it passed. I didn't get any hserr output in the jtr file when I set DEBUG on the command line. So, I modified the test to write the hserr file to system.err unconditionially (i.e. I changed the if at line 137 of MachCodeFramesInErrorFile.java to 'if (true)'.

The System.err output in the jtr file contained [MachCode] sections for 4 compiled methods, including the two that appeared in the stack listing (crashInJava3 and crashInJava2). So, I'm not sure why it is failing.

n.b. not all the System.err output ends up in the jtr file because the test harness truncates excessive output. However, I wonder if the problem you are seeing is because the original hserr file is being truncated. It includes a message to that effect starting "Output overflow: ..."

If that is the case and if you can reproduce the problem after modifying the test to write the hserr contents unconditionally then you ought to be able to see all the file contents by setting system property javatest.maxOutputSize to a suitable value (default is 100000).

@jatin-bhateja Pusha is not expected to change any registers. The inadvertent change of registers is very hard to debug. So in my thoughts it is better to have a conservative implementation currently which doesn't change RAX register.

Changes requested by wkemper (Reviewer).

src/hotspot/share/gc/shenandoah/shenandoahGeneration.cpp line 1017:

This will be a hot method. It's called by the heuristic frequently to test if it should start a GC. We may also even test this on the allocation path. I'd rather not have a log level check here just for one test case. Can we move this log message to the place where the value is updated? I expect the value to change _much less_ frequently than it is read.

I think we can cut deeper here. If `ShenandoahHeap` is now the sole source of truth for soft max heap size, can we remove the `soft_max_capacity` getter method from `ShenandoahGeneration` (and `ShenandoahSpaceInfo`)? All the callers can just get this value directly from `ShenandoahHeap` now.

Align body of methods. May be move them to the left - I don't see why we have such big spacing.

I have few comments.

src/hotspot/share/runtime/stubRoutines.cpp line 235:

> 233: SharedRuntime::_jbyte_array_copy_ctr++;      // Slow-path byte array copy
> 234: #endif // !PRODUCT

Why you removed leading spaces here and in the following methods?

src/hotspot/share/runtime/stubRoutines.cpp line 378:

> 376: #define RETURN_STUB_PARM(xxx_arraycopy, parm) {                 \
> 377:     name = parm ? #xxx_arraycopy "_uninit": #xxx_arraycopy;     \
> 378:     return StubRoutines::xxx_arraycopy(parm); }

No need these spacing changes - it was fine.

The patched entry point then redirected to SharedRuntime::handle_wrong_method(), either directly with a jump to a stub, or indirectly with an illegal instruction and the help of the signal handler.  The not_entrant state is a final state, so once an nmethod becomes not_entrant, it stays not_entrant.  We can do the same thing with a permanently armed nmethod entry barrier.

Level 0 is the outer level or layer controlled by BarrierSetNMethod::nmethod_stub_entry_barrier(), and the inner layer controlled by BarrierSetNMethod::nmethod_entry_barrier().  This could be generalized if we decide we need more flavors of entry barriers.  The inner barrier is mostly ignorant of the fact that the outer guard is multiplexing for both levels.

I would be OK with JDK-8258229 being backed out.  I sent a message to @mhaessig asking what he things.

Please see the updated code which fixes the issue by restoring the contents of RAX. The tests are passing with this update.

I'd rather not have a log level check here just for one test case. Can we move this log message to the place where the value is updated? I expect the value to change _much less_ frequently than it is read.

Agree that the debug log can be too much in the log and impact perf. There is an existing log when soft max is changed: [link](https://github.com/openjdk/jdk/blob/6df0f5e390ecf874c1eca7284c51efa65ce23737/src/hotspot/share/gc/shenandoah/shenandoahHeap.cpp#L865-L868). The problem is, before the fix, when the soft max was changed, gen shen  doesn't read the changed value. That's why I put a log here. Validating log is also indeed a bit fragile. If we remove the log, probably need to think another way to test.


For removing `soft_max_capacity`: not sure if I understand it right, but I thought `ShenandoahSpaceInfo` was the parent class in the polymorphism ([code](https://github.com/openjdk/jdk/blob/6df0f5e390ecf874c1eca7284c51efa65ce23737/src/hotspot/share/gc/shenandoah/heuristics/shenandoahAdaptiveHeuristics.hpp#L68)), so the code would work for both gen shen (ShenandoahGeneration) and ShenandoahGlobalGeneration? If we removed `soft_max_capacity ` from ShenandoahSpaceInfo, wouldn't that make heuristics not able to access soft max heap size?
