MIPS: kernel: Support extracting off-line stack traces from user-space
with perf
perf tools: Support mips unwinding and dwarf-regs
perf tools: Generate mips syscalls_n64.c syscall table
Hi Arnaldo,
The kernel part patch #1 has been merged.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1ddc96bd42da
Could the perf tool patches #2 and #3 have a chance to be merged before
5.12-rc1?
If yes, we can use this feature in 5.12-rc1.
