perf branch: Add PERF_BR_NEW_ARCH_[N] map for BRBE on arm64 platform

perf branch: Add branch privilege information request flag

2022-10-04T11:55:20+00:00

This updates the perf tools with branch privilege information request flag i.e PERF_SAMPLE_BRANCH_PRIV_SAVE that has been added earlier in the kernel. This also updates 'perf record' documentation, branch_modes[], and generic branch privilege level enumeration as added earlier in the kernel.

perf branch: Extend branch type classification

2022-10-04T11:55:20+00:00

This updates the perf tool with generic branch type classification with new ABI extender place holder i.e PERF_BR_EXTEND_ABI, the new 4 bit branch type field i.e perf_branch_entry.new_type, new generic page fault related branch types and some arch specific branch types as added earlier in the kernel. Committer note: Add an extra entry to the branch_type_name array to cope with PERF_BR_EXTEND_ABI, to address build warnings on some compiler/systems, like: 75 8.89 ubuntu:20.04-x-powerpc64el : FAIL gcc version 10.3.0 (Ubuntu 10.3.0-1ubuntu1~20.04) inlined from 'branch_type_stat_display' at util/branch.c:152:4: /usr/powerpc64le-linux-gnu/include/bits/stdio2.h:100:10: error: '%8s' directive argument is null [-Werror=format-overflow=] 100 | return __fprintf_chk (__stream, __USE_FORTIFY_LEVEL - 1, __fmt, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 101 | __va_arg_pack ()); | ~~~~~~~~~~~~~~~~~ Signed-off-by: Anshuman Khandual Cc: Alexander Shishkin Cc: Catalin Marinas Cc: Ingo Molnar Cc: James Clark Cc: Jiri Olsa Cc: Mark Rutland Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Robin Murphy Cc: Stephen Rothwell Cc: Suzuki Poulouse Cc: Thomas Gleixner Cc: Will Deacon Cc: linux-arm-kernel@lists.infradead.org Link: https://lore.kernel.org/r/20220824044822.70230-7-anshuman.khandual@arm.com Signed-off-by: Arnaldo Carvalho de Melo

perf branch: Add system error and not in transaction branch types

2022-10-04T11:55:20+00:00

This updates the perf tool with generic branch type classification with two new branch types i.e system error (PERF_BR_SERROR) and not in transaction (PERF_BR_NO_TX) which got updated earlier in the kernel. This also updates corresponding branch type strings in branch_type_name(). Committer notes: At perf tools merge time this is only on PeterZ's tree, at: git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git perf/core So for testing one has to build a kernel with that branch, then test the tooling side from: git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git perf/core Reviewed-by: James Clark Signed-off-by: Anshuman Khandual Cc: Alexander Shishkin Cc: Catalin Marinas Cc: Ingo Molnar Cc: Jiri Olsa Cc: Mark Rutland Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Robin Murphy Cc: Suzuki Poulouse Cc: Thomas Gleixner Cc: Will Deacon Cc: linux-arm-kernel@lists.infradead.org Link: https://lore.kernel.org/r/20220824044822.70230-6-anshuman.khandual@arm.com Signed-off-by: Arnaldo Carvalho de Melo
