Series perf tools: Use generic syscall scripts for all archs | expand

Message

Charlie Jenkins Jan. 9, 2025, 2:36 a.m. UTC
Standardize the generation of syscall headers around syscall tables.
Previously each architecture independently selected how syscall headers
would be generated, or would not define a way and fallback onto
libaudit. Convert all architectures to use a standard syscall header
generation script and allow each architecture to override the syscall
table to use if they do not use the generic table.

As a result of these changes, no architecture will require libaudit, and
so the fallback case of using libaudit is removed by this series.

Testing:

I have tested that the syscall mappings of id to name generation works
as expected for every architecture, but I have only validated that perf
trace compiles and runs as expected on riscv, arm64, and x86_64.

Hey, now I noticed that with this latest version we see:

While with the previous one we would see something like SYSCALLTBL as
the step name, like we have GEN, MKDIR, etc, can you take a look?

All is out there in perf-tools-next.

Ooh okay I see, the quiet commands were being ignored as-is. We could
add the lines to handle this to Makefile.syscalls, but I think the
better solution is to move the lines from Makefile.build to
Makefile.perf to be more generically available. Here is a patch for
that. I also added the comment from the kernel Makefile describing what
this does.

Subject: [PATCH] perf tools: Expose quiet/verbose variables in Makefile.perf

The variables to make builds silent/verbose live inside
tools/build/Makefile.build. Move those variables to the top-level
Makefile.perf to be generally available.
