Tiezhu Yang b5f184fbdb perf tools: Support MIPS unwinding and dwarf-regs ... Map perf APIs (perf_reg_name/get_arch_regstr/unwind__arch_reg_id) with MIPS specific registers. [ayan@wavecomp.com: repick this patch for unwinding userstack backtrace by perf and libunwind on MIPS based CPU.] [yangtiezhu@loongson.cn: Add sample_reg_masks[] to fix build error, silence some checkpatch errors and warnings, and also separate the original patches into two parts (MIPS kernel and perf tools) to merge easily.] The original patches: https://lore.kernel.org/patchwork/patch/1126521/ https://lore.kernel.org/patchwork/patch/1126520/ Committer notes: Do it as __perf_reg_name() to cope with: 067012974c ("perf tools: Fix arm64 build error with gcc-11") Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Archer Yan <ayan@wavecomp.com> Cc: David Daney <david.daney@cavium.com> Cc: Jianlin Lv <Jianlin.Lv@arm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Juxin Gao <gaojuxin@loongson.cn> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Xuefeng Li <lixuefeng@loongson.cn> Cc: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Cc: linux-mips@vger.kernel.org Link: http://lore.kernel.org/lkml/1612409724-3516-3-git-send-email-yangtiezhu@loongson.cn Signed-off-by: Archer Yan <ayan@wavecomp.com> Signed-off-by: David Daney <david.daney@cavium.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2021-03-01 14:47:50 -03:00
