@ixgbe00 Thanks a lot for the contribution! This looks good to me but I would like to ensure this works as expected. Have you successfully run "test_perf_profiler" in a RISC-V system? |
yes, I have successfully run "test_perf_profiler" in a RISC-V system. Test environment: Test content refer to https://docs.python.org/3.12/howto/perf_profiling.html (python312_perf_venv) [root@openeuler-riscv64 pytorch]# cat my_script.py def bar(n): def baz(n): if name == "main": We can run perf to sample CPU stack traces at default hertz: Then we can use perf report to analyze the data: Total Lost Samples: 0 Samples: 1K of event 'cycles:P' Overhead Samples Command Shared Object Symbol |
|
I think there is some confusion here. The test I mention is the one in the test suite: ./python -m test test_perf_profiler -v |
I am terribly sorry. Thank you very much for your answer.

Great!! Thanks a lot for checking @ixgbe00 👍 |

@Yhg1s This PR adds the trampoline to RISK-V + the configure detection. This is a new feature so technically we should not back port it, but I want us to consider adding it to 3.13 as this is quite isolated from anything else. WDYT? (Feel free to say "no") |
|
Yeah, it makes sense to backport this fix to the existing feature. |
|
Thanks @ixgbe00 for the PR, and @pablogsal for merging it 🌮🎉.. I'm working now to backport this PR to: 3.13. |

This seems incomplete. It causes compilation to now fail on riscv64, due to missing support in perf_jit_trampoline.c: |

Thank you very much for your reminder. Can we add a test program for perf jit in test_perf_profiler? |
