Hi, We have tested OpenJDK 8 (u222) (https://maxine-vm.readthedocs.io/en/latest/Status.html#platform-label) for RISC-V. Thanks |
|
Hello Prof.kotselidis @kotselidis ! |
|
I would suggest yes to change it, regarding cross compilation I am not sure we have tested it, @gigiblender do you remember? |
|
Hi @zdlgv5, you don't need to cross-compile the JDK. Fedora comes with 8u212 in its repositories and this should work with maxine. See http://fedora.riscv.rocks/koji/buildinfo?buildID=87633 https://github.com/beehive-lab/Maxine-VM-internal/blob/develop/docs/Status.rst looks wrong to me, it should say 212 for RISC-V not 222. |
|
Oh sorry, I think I miss-read your comment, it looks like you are cross-compiling the image not the JDK itself. This should work @kotselidis, see https://github.com/beehive-lab/Maxine-VM-internal/blob/develop/docs/Working-with-RISCV-on-QEMU.rst#building-maxine-vm-for-risc-v. |
|
@zdlgv5 I would use https://github.com/AdoptOpenJDK/openjdk8-binaries/releases/tag/jdk8u212-b04 instead of jdk8u222 to make sure the versions match. |
|
@zakkak thank you for reply! |
|
No unfortunately I don't. Maybe @gigiblender, @bakaliosdim, or @evankar can help you here. |
|
@zakkak I think xalan was running fine when I tested it. If @bakaliosdim or @evankar still have the different results on SpecJVM or DaCapo, I am happy to update the status page with those. If not, then I can run the benchmarks and get the results again |
|
I had tested all DaCapo RISCV64-test listed on https://github.com/beehive-lab/Maxine-VM/blob/develop/docs/Status.rst#dacapo-912-bach-mr1 and have the different results on Here is my image: https://github.com/zdlgv5/Maxine-VM_RISCV64_Dacapo_Test/blob/master/com.oracle.max.vm.native.zip, which followed the instructions in Build and Usage Instructions and Running Maxine VM on the Fedora RISC-V VM |
|
@zdlgv5 I just ran the tests again and for me
Can you run again the test so we can see if they behave the same? |
|
@bakaliosdim Oh sorry , I think that I forgot to point out that I add I just ran again with no param e.g. The results are below:
The result of sunflow: Qemu start script: Fedora info: Host Ubuntu info: |
|
I suggest adding |
I ran the benchmarks again (on a dual core setup in Qemu but in single threaded mode for the benchmarks) before and after #19 and obtained the results below. I will list only the failures: Before the trampolines patch #19 (0ab4793) :
SpecJVM2008:
After the trampolines, current develop (e213a84) :
SpecJVM2008:
As @zakkak mentioned, most of the regressed benchmarks fail in the deoptimization phase and others bailout due to the method body being larger than 1 MB |
|
Nice digging @gigiblender , so it looks like someone needs to fix deopt and possibly the 1MB bailout or we should beter revert #19 and keep in the backlog. |

I had followed the instructions in Build and Usage Instructions and Running Maxine VM on the Fedora RISC-V VM but it seems had some problems about stack, Is it the same question as #20 ? Thx a lot.
