|\ | | | | | | | | | | | | | | | | | | | | To pick up the fixes sent for v5.12 and continue development based on v5.12-rc2, i.e. without the swap on file bug. This also gets a slightly newer and better tools/perf/arch/arm/util/cs-etm.c patch version, using the BIT() macro, that had already been slated to v5.13 but ended up going to v5.12-rc1 on an older version.

* | perf cs-etm: Support PID tracing in configSuzuki K Poulose2021-03-021-12/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the kernel is running at EL2, the pid of a task is exposed via VMID instead of the CONTEXTID. Add support for this in the perf tool. This patch respects user setting if user has specified any configs from "contextid", "contextid1" or "contextid2"; otherwise, it dynamically sets config based on PMU format "contextid".

* | perf cs-etm: Update ETM metadata formatMike Leach2021-03-021-2/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | The current fixed metadata version format (version 0), means that adding metadata parameter items renders files from a previous version of perf unreadable. Per CPU parameters appear in a fixed order, but there is no field to indicate the number of ETM parameters per CPU. This patch updates the per CPU parameter blocks to include a NR_PARAMs value which indicates the number of parameters in the block. The header version is incremented to 1. Fixed ordering is retained, new ETM parameters are added to the end of the list. The reader code is updated to be able to read current version 0 files, For version 1, the reader will read the number of parameters in the per CPU block. This allows the reader to process older or newer files that may have different numbers of parameters than in use at the time perf was built.

Otherwise the last event type will be checked against all the arm_spe_pmus[i]->types, none will match and an out of bound 'i' index will be used in arm_spe_recording_init(). We don't support concurrent multiple arm_spe_x events currently, that is checked in arm_spe_recording_options(), and it will show the relevant info. So add the check and record of the first found 'arm_spe_pmu' to fix this issue here.

* perf parse: Refactor 'struct perf_evsel_config_term'Leo Yan2020-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The struct perf_evsel_config_term::val is a union which contains fields 'callgraph', 'drv_cfg' and 'branch' as string pointers. This leads to the complex code logic for handling every type's string separately, and it's hard to release string as a general way. This patch refactors the structure to add a common field 'str' in the 'val' union as string pointer and remove the other three fields 'callgraph', 'drv_cfg' and 'branch'. Without passing field name, the patch simplifies the string handling with macro ADD_CONFIG_TERM_STR() for string pointer assignment. This patch fixes multiple warnings of line over 80 characters detected by checkpatch tool.

| | | | | | | | | | | | | | | | | | | | | | | And pick the shortest name: 'struct maps'. The split existed because we used to have two groups of maps, one for functions and one for variables, but that only complicated things, sometimes we needed to figure out what was at some address and then had to first try it on the functions group and if that failed, fall back to the variables one. That split is long gone, so for quite a while we had only one struct maps per struct map_groups, simplify things by combining those structs. First patch is the minimum needed to merge both, follow up patches will rename 'thread->mg' to 'thread->maps', etc. Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Link: https://lkml.kernel.org/n/tip-hom6639ro7020o708trhxh59@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
* perf tools: Avoid 'sample_reg_masks' being const + weakIan Rogers2019-10-102-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Being const + weak breaks with some compilers that constant-propagate from the weak symbol. This behavior is outside of the specification, but in LLVM is chosen to match GCC's behavior. LLVM's implementation was set in this patch: https://github.com/llvm/llvm-project/commit/f49573d1eedcf1e44893d5a062ac1b72c8419646 A const + weak symbol is set to be weak_odr: https://llvm.org/docs/LangRef.html ODR is one definition rule, and given there is one constant definition constant-propagation is possible. It is possible to get this code to miscompile with LLVM when applying link time optimization. As compilers become more aggressive, this is likely to break in more instances. Move the definition of sample_reg_masks to the conditional part of perf_regs.h and guard usage with HAVE_PERF_REGS_SUPPORT. This avoids the weak symbol. Fix an issue when HAVE_PERF_REGS_SUPPORT isn't defined from patch v1. In v3, add perf_regs.c for architectures that HAVE_PERF_REGS_SUPPORT but don't declare sample_regs_masks. Further notes: Jiri asked: "Is this just a precaution or you actualy saw some breakage?" Ian answered: "We saw a breakage with clang with thinlto enabled for linking. Our compiler team had recently seen, and were surprised by, a similar issue and were able to dig out the weak ODR issue."
