Subject: [PATCH v4 00/16] perf tools: Use generic syscall scripts for all archs
Date: Wed, 18 Dec 2024 01:23:58 -0800 [thread overview]
Message-ID: <20241218-perf_syscalltbl-v4-0-bc8caef2ca8e@rivosinc.com> (raw)
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.
