Add a help to create a system-wide sched_switch event. One merit is that it sets the system-wide bit before adding it to evlist so that the libperf can handle the cpu and thread maps correctly. Reviewed-by:

The cpu and thread maps are properly handled in libperf now. No need to do it in the perf tools anymore. Let's remove the logic. Reviewed-by:

Namhyung Kim authored
The current code propagate evsel's cpu map settings to evlist when it's added to an evlist. But the evlist->all_cpus and each evsel's cpus will be updated in perf_evlist__set_maps() later. No need to do it before evlist's cpus are set actually. In fact it discards this intermediate all_cpus maps at the beginning of perf_evlist__set_maps(). Let's not do this. It's only needed when an evsel is added after the evlist cpu/thread maps are set. Reviewed-by:

Setting proper cpu and thread maps for system wide evsels regardless of user requested cpu in __perf_evlist__propagate_maps(). Those evsels need to be active on all cpus always. Do it in the libperf so that we can guarantee it has proper maps. Reviewed-by:

Some TMA metrics have double if expressions like: ( CPU_CLK_UNHALTED.THREAD / 2 ) * ( 1 + CPU_CLK_UNHALTED.ONE_THREAD_ACTIVE / CPU_CLK_UNHALTED.REF_XCLK ) ) if #core_wide < 1 else ( CPU_CLK_UNHALTED.THREAD_ANY / 2 ) if #SMT_on else CPU_CLK_UNHALTED.THREAD This currently fails to parse as the left hand side if expression needs to be in parentheses. By allowing the if expression to have a right hand side that is an if expression we can parse the expression above, with left to right evaluation order that matches languages like Python.

Unused macros reported by [-Wunused-macros]. This macros were introduced as __PERF_COUNTER_FIELD and used for reading the bit in config. cdd6c482 ("perf: Do the big rename: Performance Counters -> Performance Events") Changes it to __PERF_EVENT_FIELD but at this commit there is already nowhere else using these macros, also no macros called PERF_EVENT_##name##_MASK/SHIFT. Now we are not reading type or id from config. These macros are useless and incomplete. So removing them for code cleaning. Signed-off-by:

When perf is built in a full source tree that is not a git repository, e.g. from a kernel source tarball, `perf version` will print empty tag and commit strings: $ perf version perf version Currently the tag version is only generated from the root Makefile when building in a git repository. If PERF-VERSION-FILE has not been generated and the source tree is not in a git repository, then PERF-VERSION-GEN will return an empty version. The problem can be reproduced with the following steps: $ wget https://git.kernel.org/torvalds/t/linux-6.0-rc7.tar.gz $ tar -xf linux-6.0-rc7.tar.gz && cd linux-6.0-rc7 $ make -C tools/perf $ tools/perf/perf -v perf version Builds from tarballs generated with `make perf-tar-src-pkg` are not impacted by this issue as PERF-VERSION-FILE is included in the archive. The perf RPM provided by Fedora for 5.18+ is experiencing this problem. Package build logs[0] show that the build is attempting to fall back on PERF-VERSION-FILE, but it is not present. To resolve this, revert back to the previous logic of using the kernel Makefile version if not in a git repository and PERF-VERSION-FILE does not exist.

When parsing flags in filter, the strtoul function uses wrong parsing condition (tok[1] = 'x'), which can make the flags be corrupted and treat all numbers start with 0 as hex. In fact strtoul() will auto test hex format when base == 0 (See _parse_integer_fixup_radix). So there is no need to test this again. Remove the unnessesary is_hexa test.

trace__fprintf_tp_fields() will always print arg names because when implemented it is forced to print arg_names with: (1 || trace->show_arg_names) So the printing looks like: > cat ~/.perfconfig [trace] show_arg_names = no > perf trace -e syscalls:*mmap sleep 1 0.000 sleep/1119 syscalls:sys_enter_mmap(NULL, 8192, READ|WRITE, PRIVATE|ANONYMOUS) 0.179 sleep/1119 syscalls:sys_exit_mmap(__syscall_nr: 9, ret: 140535426170880) ... Although the comment said that perhaps we need a show_tp_arg_names. I don't think it's necessary to control them separately because it's not so clean that part of the log shows arg names but other not. Also when we are tracing functions it's rare to especially distinguish syscalls and tp trace. Only use one option to control arg names printing is more resonable and simple. So remove the force condition and commit. After fix: > perf trace -e syscalls:*mmap sleep 1 0.000 sleep/1121 syscalls:sys_enter_mmap(NULL, 8192, READ|WRITE, PRIVATE|ANONYMOUS) 0.163 sleep/1121 syscalls:sys_exit_mmap(9, 140454467661824) ...
