From: Tiezhu Yang
Date: Wed Feb 03 2021 - 22:36:55 EST
v2: add R26 and R27 to the enum perf_event_mips_regs in patch #1
Tiezhu Yang (3):
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
