@MichelleJin12 I updated some codes. :) Thanks for your first drafts.

@gichoel I think same with aarch64. We need to double checking.

As you may already know, the RISC-V architecture does not yet support dynamic tracing. Therefore, related code must be added after introducing Dynamic Tracing in the RISC-V architecture.

For the above reasons and to reduce confusion, I think you should remove riscv from the patch_size variable in that code, so that the string fpatchable-function-entry not support on current platform is printed and the program exits.

Additionally, although I'm not sure yet, there is a commit that forces RISC-V kernels to use -fpatchable-function-entry=8, so you should check if you can use the same value as aarch64.
ref. https://git.kernel.org/torvalds/c/afc76b8b8011

Thanks for the review. I will include both @MichelleJin12 @gichoel feedback. :)

Are there nice nightly checking? This because Rust compiler flags +nightly -Z instrument-mcount needed. :)

Here is some point of non-deterministic behavior occurred.

MichelleJin12 · 2023-10-29T07:12:34Z

How about splitting it into a commit for risc-v and a commit for rust test?

paranlee · 2023-10-29T07:15:46Z

@MichelleJin12 I thought a lot about whether to include that code or not, so I added it, but it makes sense.
The RISC-V related 2 part looks good enough to be used in other tasks in the future.

MichelleJin12 · 2023-10-29T07:33:06Z

There is a bug where an error occurs if the s-abc executable file is not already created. You should run the build command once to create s-abc.

$ ./runtest.py -vdp -R 001

I think you need to delete [PATCH] from the subject of the commit message.
You can modify the signature as below to pass the DCO. :)
