Re: Does AIX support the Xrandr extension?

I've just pushed the fix (http://hg.openjdk.java.net/jdk/jdk/rev/2d18e5ed0f8d) for "8213944: Fix AIX build after the removal of Xrandr.h and add a configure check for it" (https://bugs.openjdk.java.net/browse/JDK-8213944) which solves the problem by disabling Xrandr support at compile time.

[8u] RFR for backport of JDK-8188868: PPC64: Support AES intrinsics on Big Endian
by Kazunori Ogata 21 Nov '18

21 Nov '18

Hi, May I get reviews for enhancement backport of JDK-8188868: PPC64: Support AES intrinsics on Big Endian? http://cr.openjdk.java.net/~horii/jdk8u_aes_be/8188868/webrev.00/ There is no code change except for an immediate parameter of vsldoi (-8 in jdk8u was changed to 8 to match with the latest code), besides the difference of directory tree structure. Since not a small number of customers are still using jdk8, especially in AIX, JDK-8188868 is important for them to improve performance of secure network transportation. Regards, Ogata

Does AIX support the Xrandr extension?
by Volker Simonis 20 Nov '18

20 Nov '18

Hi AIX experts, a recent change ("8210863: Remove Xrandr include files from JDK sources" [1]) has removed the Xrander header files which were previously checked in in the OpenJDK sources, from there. This means that the build now requires the platform version of these header files: X11/extensions/Xrandr.h X11/extensions/randr.h To the best of my knowledge, AIX does not support the Xrandr extension and I couldn't find the corresponding header files any where (even not in the "AIX Toolbox for Linux Applications" [2]). I've therefor prepared a change which fixes these issues on AIX (see: http://mail.openjdk.java.net/pipermail/2d-dev/2018-November/009636.html) However, before pushing this fix, I'd like to get a confirmation if Xrandr is indeed not supported and not available on AIX. If it is, please point me to a place where I can get a package with the corresponding header files. Thank you and best regards, Volker [1] https://bugs.openjdk.java.net/browse/JDK-8210863 [2] https://www.ibm.com/developerworks/aix/library/aix-toolbox/alpha.html

RFR(S): 8213436: Obsolete UseMembar
by Mikael Vidstedt 08 Nov '18

08 Nov '18

Please review this change which obsoletes the UseMembar flag and removes the code that then becomes unreachable/dead. bug: https://bugs.openjdk.java.net/browse/JDK-8213436 <https://bugs.openjdk.java.net/browse/JDK-8213436> webrev: http://cr.openjdk.java.net/~mikael/webrevs/8213436/webrev.00/open/webrev/ <http://cr.openjdk.java.net/~mikael/webrevs/8213436/webrev.00/open/webrev/> * Background (from jbs) The UseMembar flag was deprecated in JDK 10, and is default true/enabled on all platforms since that same release. It should be obsoleted and the then dead serialization page functionality it controls should be removed. * Testing tier1. If anybody wants to take it for a spin on aarch64/ppc/s390/x86_32 that wouldn’t hurt. (Unrelated to this change: It would be really nice to clean up some of the (mostly) duplicated code in the os/signal handling area...) Cheers, Mikael

RFR: 8212794 IBM-964 and IBM-29626C are required for AIX default charset
by Ichiroh Takiguchi 08 Nov '18

08 Nov '18

Hello. Could you review the fix ? Bug: https://bugs.openjdk.java.net/browse/JDK-8212794 Change: https://cr.openjdk.java.net/~itakiguchi/8212794/webrev.00/ I'd like to obtain a sponsor for this issue. IBM964 charset and IBM29626C charset are required for default charset on AIX zh_TW and ja_JP locale. OpenJDK already has IBM964, but it could not be configured for default charset. IBM29626C is new one. (IBM33722 extends IBM29626C class) I knew IBM charsets would need to move to somewhere. The discussion was started by "Adding new IBM extended charsets". [1] But it's related default charset issue. Please put them inside of OpenJDK. About IBM964, Bhaktavatsal started the discussion [2]. Sherman said that [3] the new model (open/make/data/charetmapping), instead of hard-coding the map into the source code. This fix only has small sized hard-coded mapping, IBM964/IBM29626C/IBM33722 refer other charsets conversion table which are using the new model. And class file is smaller then before. Still I used SimpleEUCEncoder class because it's stable. I think we may re-write it by IBM charsets renewal. Thanks, Ichiroh Takiguchi IBM Japan, Ltd.

RFR(S): 8212481: PPC64: Enable POWER9 CPU detection
by Gustavo Romero 31 Oct '18

31 Oct '18

Hi, Could the following small change be reviewed please? Bug : https://bugs.openjdk.java.net/browse/JDK-8212481 Webrev: http://cr.openjdk.java.net/~gromero/8212481/v1/ It adds 'darn' instruction introduced with POWER9 CPUs to the Macroassembler and uses it to set PowerArchitecturePPC64 to POWER9 when the instruction is available on the CPU so it can be used in the future by any POWER9-specific JVM code or by any JVM code specifically dependent on the 'darn' instruction, using VM_Version::has_darn(). It was checked on POWER9 as the following: gromero@ltc-wspoon3:~/POWER9/jdk12_tip_f53671e05660+/jvm/openjdk-12-internal/bin$ lscpu Architecture: ppc64le Byte Order: Little Endian CPU(s): 176 On-line CPU(s) list: 0-175 Thread(s) per core: 4 Core(s) per socket: 22 Socket(s): 2 NUMA node(s): 8 Model: 2.2 (pvr 004e 1202) Model name: POWER9 (raw), altivec supported CPU max MHz: 2800.0000 CPU min MHz: 2300.0000 L1d cache: 32K L1i cache: 32K L2 cache: 512K L3 cache: 10240K NUMA node0 CPU(s): 0-87 NUMA node8 CPU(s): 88-175 NUMA node250 CPU(s): NUMA node251 CPU(s): NUMA node252 CPU(s): NUMA node253 CPU(s): NUMA node254 CPU(s): NUMA node255 CPU(s): gromero@ltc-wspoon3:~/POWER9/jdk12_tip_f53671e05660+/jvm/openjdk-12-internal/bin$ LD_SHOW_AUXV=1 /bin/true | egrep "HWCAP|PLATFORM" AT_HWCAP: true_le archpmu vsx arch_2_06 dfp ic_snoop smt mmu fpu altivec ppc64 ppc32 AT_HWCAP2: darn ieee128 arch_3_00 vcrypto tar isel ebb dscr arch_2_07 AT_PLATFORM: power9 AT_BASE_PLATFORM:power9 gromero@ltc-wspoon3:~/POWER9/jdk12_tip_f53671e05660+/jvm/openjdk-12-internal/bin$ ./java -XX:+Verbose -version dscr value was 0x10 Version: ppc64 fsqrt isel lxarxeh cmpb popcntb popcntw fcfids vand lqarx aes vpmsumb mfdscr vsx ldbrx stdbrx sha darn L1_data_cache_line_size=128 openjdk version "12-internal" 2019-03-19 OpenJDK Runtime Environment (fastdebug build 12-internal+0-f53671e05660.dirty.debug.POWER9) OpenJDK 64-Bit Server VM (fastdebug build 12-internal+0-f53671e05660.dirty.debug.POWER9, mixed mode, sharing) It was also checked on POWER8 and no regression was observed: gromero@gromero16:~/openjdks/jdk12_tip_f53671e05660+/jvm/openjdk-12-internal/bin$ lscpu Architecture: ppc64le Byte Order: Little Endian CPU(s): 80 On-line CPU(s) list: 0-79 Thread(s) per core: 8 Core(s) per socket: 10 Socket(s): 1 NUMA node(s): 1 Model: 2.1 (pvr 004b 0201) Model name: POWER8 (architected), altivec supported Hypervisor vendor: horizontal Virtualization type: full L1d cache: 64K L1i cache: 32K NUMA node0 CPU(s): 0-79 gromero@gromero16:~/openjdks/jdk12_tip_f53671e05660+/jvm/openjdk-12-internal/bin$ LD_SHOW_AUXV=1 /bin/true | egrep "HWCAP|PLATFORM" AT_HWCAP: archpmu vsx arch_2_06 dfp ic_snoop smt mmu fpu altivec ppc64 ppc32 AT_HWCAP2: htm-nosc vcrypto tar isel ebb dscr htm arch_2_07 AT_PLATFORM: power8 AT_BASE_PLATFORM:power8 gromero@gromero16:~/openjdks/jdk12_tip_f53671e05660+/jvm/openjdk-12-internal/bin$ ./java -XX:+Verbose -version dscr value was 0x0 Version: ppc64 fsqrt isel lxarxeh cmpb popcntb popcntw fcfids vand lqarx aes vpmsumb mfdscr vsx ldbrx stdbrx sha rtm L1_data_cache_line_size=128 openjdk version "12-internal" 2019-03-19 OpenJDK Runtime Environment (fastdebug build 12-internal+0-f53671e05660.dirty.debug.POWER9) OpenJDK 64-Bit Server VM (fastdebug build 12-internal+0-f53671e05660.dirty.debug.POWER9, mixed mode, sharing) Thank you.

RFR: 8211908: PPC64: Enable SuperWordLoopUnrollAnalysis by default
by Michihiro Horie 10 Oct '18

10 Oct '18

Dear all, Would you please review this simple change? Bug: https://bugs.openjdk.java.net/browse/JDK-8211908 Webrev: http://cr.openjdk.java.net/~mhorie/8211908/webrev.00 Since PPC64 supports SLP with VSX, we can have the benefit from enabled SuperWordLoopUnrollAnalysis on PPC64. In the attached micro benchmarks, performance improved by 1.7x at maximum. In SPECjvm2008, the score improved by a couple of % in xml.validation and scimark.lu.large (See attached file: microbench_slp.tar.gz) Best regards, -- Michihiro, IBM Research - Tokyo
