Hi all,

The RISC-V Port Project has been recorded in the OpenJDK Census [1]. 

We already have the repo [2] and the mailing list (pre-populated with initial Reviewers) [3]. 
The "master" branch is seeded with the most recent gh:openjdk/jdk and will automatically be sync'd to that repo. 
I will push a new "riscv-port" branch to the Project repo. Future Project development should happen on this new branch. 

We also have a web page [4] and a wikispace [5]. 
Note that the wikispace is still being setup, and we need to wait for write access permission. 
I'll add something more on the wiki page once it's ready for editing. 

The next thing for me to do is to propose the current code from the riscv-port-branch of jdk-sandbox
as GitHub Pull-Request. This course made things simpler from the legal point of view. 

It would be beneficial to track our future issues in JBS. I will ask ops to add "riscv" as a CPU target.
Like other Projects, we also need project-specific entries for the Affected and Fix Version fields, e.g. JDK-8251041 [6].
I think we can do the same.

Aleksey Shipilev is building nightlies here [7]. And we've provided build instructions for reference [8].
You can try the RISC-V JDK with QEMU User/System mode or HiFive Unleashed/Unmatched board.

Have fun and happy hacking!

Thanks,
Felix

This riscv64 port supports RV64GV, shorthand for RV64IMAFDV ISA extensions, and covers the templateInterpreter, C1 and C2, excluding AOT/JVMCI. All existing GCs are available on riscv64, including ZGC and ShenandoahGC.

Passed jtreg tier{1,2,3,4} and jcstress tests on HiFive Unmatched board. SPECjbb & SPECjvm benchmark tests are also carried out regularly. So it should be good enough to run most Java programs.

Honestly, you could just push it :) No need for PR for the first import.

Thanks for taking care of that :-)
Some update:
I have pushed new "riscv-port" branch and imported the initial code for this port [1]. 
Also, the JBS has been updated with extra settings for this project. Here is an example issue for reference [2].

Hi team,

x3 is a special register on RISCV and we should not use it as a register allocation candidate - if users write JNI programs referencing global variables, where ld could link global reference loading logic to an instruction like 'ld $Rtmp, $offset(x3)', and try to call vm functions, C1 will zap x3's value and causes a crash. It seems C2 doesn't use x3 so we are just aligning the logic with C2 properly.

Thanks,
Xiaolin

Hi team -

Simply fix a register name string: `lr` is `names[1]` so `names[5]` should be `x5`.

Looks good. I suggest typo fixes like this be combined into other non-trivial PRs in future.

Yes - hotspot/jdk full tiers' results look good. This patch is directly cherry-picked from [that patch](https://github.com/riscv-collab/riscv-openjdk/pull/2). Would you like to have another simple review? Thanks.

Seems the third checkbox needs a mark.

I think we need another Reviewer here.  Maybe @shipilev ?
According to OpenJDK bylaws, a Project?s Lead is automatically considered to be a Reviewer.
But looks like the robot does not follow this rule correctly for now. I am asking the registrar about this.

 MacroAssembler::get_thread() using tls.ie
Message-ID: <PkHMUvs8f8McIH37c9jpK75R6nqPcUAL2oPd1XyUaYI=.03b608b5-0977-4045-855f-38a89d3b7639@github.com>

Hi team,

This patch fixes the unimplemented assembly version of `__ get_thread()`, bringing some performance improvement by directly using the x4 register to refer to the variable `Thread::_thr_current`. Tested tests under hotspot/ and jdk/. [Original patch](https://github.com/riscv-collab/riscv-openjdk/pull/4)

Thanks,
Xiaolin

Subject: [riscv-port] RFR: 8277392: riscv: Port missing trampoline logic from
 AArch64 platform
Message-ID: <PegsqRLjUDmwckjcVkQiItOgBvnGCmjshOSocMQ21Dw=.eee8ad9f-e6c3-4051-bab1-313ea6d911c1@github.com>

Hi team,

Java calls will jump to the trampoline stub even if the target address is directly reachable by using a simple `jal` before this patch. After adding back the logic from the AArch64 platform, we find a nearly 4% performance enhancement on SPECjbb2005/15. Tested tests under hotspot/ and jdk/. [Original Patch](https://github.com/riscv-collab/riscv-openjdk/pull/8)

Thanks,
Xiaolin

Currently, there are two register declarations for both 'ra' and 'lr' on riscv port. But they refer to the same register x1. Since 'ra' is the ABI name for register x1, we should keep register declaration for 'ra' and remove register declaration for 'lr' in order to avoid possible confusion.

Nice cleanup. Looks good.

Subject: [riscv-port] RFR: 8277036: riscv: Get CPU features from the auxiliary
 vector on Linux
Message-ID: <UQ3X7RGqwtDnvDx3QmHzRiDv9d9_P3KejlKLJ7EyTAQ=.eaf71c18-50d0-450a-a3a4-4f9698ef91b7@github.com>

Due to the lack of native environment in our early development of riscv port, we detect riscv CPU ISA extensions through checking whether simulator (e.g. QEMU) supports execution of one of the instructions in the corresponding feature spec or not. Fortunately, there are several riscv hardwares available now, we can directly get this CPU info from the auxiliary vector on Linux. Note that the aarch64 port also did the same thing on Linux platform.

This has been tested on HiFive Unleashed board (rv64imafdc) and NeZha D1 board (rv64imafdcvu):

For maximum flexibility, I would suggest we switch to use the global-dynamic TLS model here if you don't have a strong reason to use the initial-exec TLS model. That's the default TLS model used by the host GCC compiler and I don't want to affected by the limits of the initial-exec TLS model some day.

Currently, riscv port supports vector operations which is fully compatible with vector extension 1.0 spec. And we have passed tier 1-4 tests with option "-XX:+UseVExt" with QEMU.

Due to lack of native environment which supports vector extension 1.0, we cannot carry out tests for vector operations on real hardware. So we decided to move port-specific option UseVExt from product to experimental for now, and rename UseVExt to UseRVV.

This also fixes some typos in comments, and  removes unused v extension instructions.

The test results on HiFive Unleashed board (rv64imafdc) and NeZha D1 board (rv64imafdcvu) are in line with expectations.

Is RVV still a product flag?

UseRVV is only available as experimental option on this platform. It must be enabled via -XX:+UnlockExperimentalVMOptions flag.

It's better to write like this:

  product(bool, UseRTMForStackLocks, false, EXPERIMENTAL,                   \
          "Enable RTM lock eliding for stack locks in compiled code")       \

Hi Felix -

Quite sorry for the late reply - it takes me some time to look up some references. This code looks great without any problem and I totally agree with your point - so it is hard to make me not think you have implemented one version already in your codebase :-)  And `__tls_get_addr`'s implementation could found itself at [this link](https://sources.debian.org/src/glibc/2.31-13/sysdeps/riscv/libc-tls.c/) with [macros defined](https://sources.debian.org/src/glibc/2.31-13/sysdeps/riscv/nptl/tls.h/), which is a C function. With this respect, it seems that I also need to save and restore all volatile registers pessimistically in `MacroAssembler::get_thread`, same as the current implementation on the master branch. I think it might be hard to keep the saved registers the same as AArch64's implementation that only clobbers x1 - please correct me if I missed something. But this seems much cheaper than calling a [pthread_getspecific](https://sources.debian.org/src/glibc/2.32-4/nptl/pthread_gets
 pecific.c/?hl=24#L24). In fact, the first version of this patch is written in a similar way as yours - for better performance I chose to use tls.ie - but I think you hold a very reasonable point.

It's Friday night so please feel free to move the discussion to weekdays.

Thanks -
Xiaolin

This code looks great without any problem and I totally agree with your point - so it is hard to make me not think you have implemented one version already in your codebase :-)  And `__tls_get_addr`'s implementation could found itself at [this link](https://sources.debian.org/src/glibc/2.31-13/sysdeps/riscv/libc-tls.c/) with [macros defined](https://sources.debian.org/src/glibc/2.31-13/sysdeps/riscv/nptl/tls.h/), which is a C function. With this respect, it seems that I also need to save and restore all volatile registers pessimistically in `MacroAssembler::get_thread`, same as the current implementation on the master branch. I think it might be hard to keep the saved registers the same as AArch64's implementation that only clobbers x1 - please correct me if I missed something. But this seems much cheaper than calling a [pthread_getspecific](https://sources.debian.org/src/glibc/2.32-4/nptl/pthread_ge
 tspecific.c/?hl=24#L24). In fact, the first version of this patch is written in a similar way as yours - for better performance I chose to use tls.ie - but I think you hold a very reasonable point.

Seems `get_thread()` is only used in debug code on AArch64 and RISCV -- I have pushed revised code and now hotspot and jdk tier1 are under testing. I will ping this thread when tests are done.

Message-ID: <cHj-06v54QQIuFXvPNopEl-NvshBWeaZktDqyOj1h8Y=.01637c75-3570-4cc0-a54e-6b0031a0d844@github.com>

According to https://bugs.openjdk.java.net/browse/JDK-8277180, the C2 fast_lock and fast_unlock intrinsics don't support recursive ObjectMonitor locking. Some workload can significantly benefit from this. This fixes the problem on riscv.
Tier1 tests of hotspot and jdk are passed on unmatched and all JTreg tests are tested on qemu without new failures.

After some reconsideration, I think we can go one step further: simply keep the changes in file src/hotspot/share/utilities/globalDefinitions_gcc.hpp and remote all other changes in this PR.

Then USE_LIBRARY_BASED_TLS_ONLY macro won't be defined and Thread::current() will return '_ZN6Thread12_thr_currentE' in that case. This will be the same in functionality as the newly add assembly function '_ZN10JavaThread25riscv64_get_thread_helperEv'.

I have checked with Yadong, the reason for defining USE_LIBRARY_BASED_TLS_ONLY macro is to workaround some host compiler bug when accessing TLS variables in the very early days. This should not affect us now.

I think I get your point - I wonder if that `remote` should actually be a `revert`?
If it is - that's great - I think this is a pretty and concise solution if we need to clobber all volatile registers anyway. Let me revise this patch and change the titles.
But calling a `call_VM_leaf_base()` is a bit duplicated because this function would save another bunch of registers like x5 and x31 again, so I would recommend directly using a pair of `movptr_with_offset` and `jalr` - though it might be insignificant.

Sorry for the typo. Should be "remove". Please do.
We should keep your original changes about the comment for MacroAssembler::get_thread(Register thread) at the same time :-)

Simply tested a `test/hotspot/jtreg/compiler` folder on qemu and no more errors found. Would you mind having another review of this patch? I feel pleased to receive any suggestion.

It would be interesting to know how this may affect performance on riscv. Maybe we can try DaCapo h2 to see.

It's an optional, maybe only for debug, to check the owner of the lock in the fast_unlock intrinsic in riscv, which already applied in AArch64.

Message-ID: <y9gbfv73CLIeBzqg_HeObGAaJ6RdHc98So3p5m9Wxkw=.4432d723-dac6-4075-8ef6-1b0839344bf3@github.com>

Hi team,

According to https://bugs.openjdk.java.net/browse/JDK-8277884 and [the original patch](https://github.com/riscv-collab/riscv-openjdk/pull/15):

A very simple program inherited from jcstress could reproduce this:


import java.lang.invoke.MethodHandles;
import java.lang.invoke.VarHandle;

// run with:
// build/linux-riscv64-server-release/images/jdk/bin/java -ea -XX:-TieredCompilation -XX:CompileCommand=compileonly,jdk.internal.misc.Unsafe::compareAndSetByte TestCASByte
// assert will fail.
// if we add '-XX:+UnlockDiagnosticVMOptions -XX:DisableIntrinsic=_compareAndExchangeByte' this test will pass.

public class TestCASByte {

    byte[] array = new byte[1];

    static final VarHandle vh;
    static {
        try {
            vh = MethodHandles.arrayElementVarHandle(byte[].class);
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    public void test() {
        for (int i = 0; i < 100_000; i++) { // To level 4
            // clear
            array[0] = 0;

            byte res1 = (byte)vh.getAndSet(array, 0, (byte)-1);
            byte res2 = (byte)vh.getAndSet(array, 0, (byte)2);

            assert res1 == 0 && res2 == -1;
        }
    }

    public static void main(String[] args) {
        new TestCASByte().test();
    }

}


In this case when we are getting the -1 value saved in memory, the shift is 0, the old is 0x00000000000000ff and the mask is 0x00000000000000ff at the end of cmpxchg_narrow_value. The final result is 0x00000000000000ff but it indeed should be 0xffffffffffffffff. BTW the shift is 0. Therefore, if the result is negative, we need to make a sign extension.

Thanks,
Xiaolin

Hi team,

A trivial fix for a small C1 crash - this issue could be directly reproduced by using `java -XX:+UseSerialGC -XX:-UseTLAB -XX:TieredStopAtLevel=1`. The reason is simple: the eden_allocate uses t2 as a register and zaps it, whereas C1 will use it as a register allocation candidate, leading to a crash. In this function, t0 never gets a use so we can use it safely. Tested in all cases. [The original patch](https://github.com/riscv-collab/riscv-openjdk/pull/15)

Thanks,
Xiaolin

Looks good.
I can also reproduce the bug  with following three jcstress tests:
org.openjdk.jcstress.tests.atomicity.varHandles.fields.GetAndSetTest.GetAndSetByte
org.openjdk.jcstress.tests.atomicity.varHandles.fields.GetAndSetTest.GetAndSetShort
org.openjdk.jcstress.tests.atomicity.varHandles.arrays.GetAndSetTest.GetAndSetByte

Quite thanks for the supplementary information about the failed tests.
A simple `test/hotspot/jtreg/compiler` on Qemu seems no error found. And these three jcstress tests seem no `FORBIDDEN` occurrences after this patch.

No need to introduce local variable "tmp" here. I think we can use t0 directly here.

Looks good. It's definitely inappropriate to use an allocatable general-purpose register here.

This is a reasonable point -- changed as proposal, passed fastdebug build, and tested a simple `java -XX:+UseSerialGC -XX:-UseTLAB -XX:TieredStopAtLevel=1`.

This bug can be reproduced by `java -XX:+UseSerialGC -XX:-UseTLAB -XX:TieredStopAtLevel=1 -version` on the unmatched board where this command will hang. The reason is that the implementation of load reserved/store conditional loop in BarrierSetAssembler::eden_allocate breaks the RISC-V Atomic extension spec:

For the
sequence to be guaranteed to eventually succeed, the dynamic code executed between the LR and
SC instructions can only contain other instructions from the base \I" subset, excluding loads, stores,
backward jumps or taken backward branches, FENCE, FENCE.I, and SYSTEM instructions.

It may cause an unspecified behaviour depends on specific hardware implementations.

UseRVV could cause crash on D1 board(RISCV-C906).

It seems that though the D1 board is equipped with RVV-0.7.1[1] . In our test, VLENB CSR can return value of 16 on D1 board. So JDK will assume it can support RVV extension and crash in vector instructions when  UseRVV is enabled.  

RVV-0.9 and above[2] introduce a new VCSR CSR register, it will raise SIGILL on D1 board. So we can check it to detect vext support.

This might unnecessarily complicated the issue tbh. If you want to distinguish the specific cpu/core vendor, I would suggest we do in some different way. One possible way would be through checking /proc/cpuinfo for this infomation like aarch64 port [1]. I see boards like hifive unleashed and unmatched also provide necessary microarchitecure version through /proc/cpuinfo [2]. I think this kind of infomation should be made available in the system.

Thanks for your comment. My first thinking is to check /proc/cpuinfo . But it doesn't provide cpu model information. Below is /proc/cpuinfo from Fedora31 on D1:

[riscv at fedora-riscv ~]$ cat /proc/cpuinfo
processor       : 0
hart            : 0
isa             : rv64imafdcvu
mmu             : sv39

Is it a OS porting problem? See `cat /proc/cpuinfo` from Ubuntu 21.04 on unmatched:

processor	: 0
hart		: 2
isa		: rv64imafdc
mmu		: sv39
uarch		: sifive,u74-mc
