Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: - Show precise number of samples in at the end of a 'record' session, if processing build ids, since we will then traverse the whole perf.data file and see all the PERF_RECORD_SAMPLE records, otherwise stop showing the previous off-base heuristicly counted number of "samples" (Namhyung Kim). - Support to read compressed module from build-id cache (Namhyung Kim) Infrastructure changes: - Cache eh/debug frame offset for dwarf unwind (Namhyung Kim) - Set header version correctly in all cases (Namhyung Kim) - Set attr.task bit for a tracking event, to be consistent (Namhyung Kim) perf tools: Use perf_data_file__fd() consistently perf symbols: Convert lseek + read to pread - Don't rely on malloc working for sz 0, fixing another problem when using uClibc (Vineet Gupta) - Provide stub for missing pthread_attr_setaffinity_np for libcs where this is not available, such as uClibc (Vineet Gupta) Signed-off-by:

When dso_cache__read() is called, it reads data from the given offset using lseek + normal read syscall. It can be combined to a single pread syscall. Signed-off-by:

The commit c00c48fc ("perf symbols: Preparation for compressed kernel module support") added support for compressed kernel modules but it only supports system path DSOs. When a dso is read from build-id cache, its filename doesn't end with ".gz" but has build-id. In this case, we should fallback to the original dso->name. Signed-off-by:

The perf_event_attr.task bit is to track task (fork and exit) events but it missed to be set by perf_evsel__config(). While it was not a problem in practice since setting other bits (comm/mmap) ended up being in same result, it'd be good to set it explicitly anyway. The attr->task is to track task related events (fork/exit) only but other meta events like comm and mmap[2] also needs the task events. So setting attr->comm and/or attr->mmap causes the kernel emits the task events anyway. So the attr->task is only meaningful when other bits are off but I'd like to set it for completeness.

After perf record finishes, it prints file size and number of samples in the file but this info is wrong since it assumes typical sample size of 24 bytes and divides file size by the value. However as we post-process recorded samples for build-id, it can show correct number like below. If build-id post-processing is not requested just omit the wrong number of samples. $ perf record noploop 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.159 MB perf.data (3989 samples) ] $ perf report --stdio -n # To display the perf.data header info, please use --header/--header-only options. # # Samples: 3K of event 'cycles' # Event count (approx.): 3771330663 # # Overhead Samples Command Shared Object Symbol # ........ ............ ....... ................ .......................... # 99.90% 3982 noploop noploop [.] main 0.09% 1 noploop ld-2.17.so [.] _dl_check_map_versions 0.01% 1 noploop [kernel.vmlinux] [k] setup_arg_pages 0.00% 5 noploop [kernel.vmlinux] [k] intel_pmu_enable_all Reported-by:Milian Wolff <mail@milianw.de> Signed-off-by:

It's only used for perf record to process build-id because its file size it's not fixed at this time due to remaining header features. However data offset and size is available so that we can use the perf_session__process_events() once we set the file size as the current offset like for now. Signed-off-by:

The fix from 9fc81d87 ("perf: Fix events installation during moving group") was incomplete in that it failed to recognise that creating a group with events for different CPUs is semantically broken -- they cannot be co-scheduled. Furthermore, it leads to real breakage where, when we create an event for CPU Y and then migrate it to form a group on CPU X, the code gets confused where the counter is programmed -- triggered in practice as well by me via the perf fuzzer. Fix this by tightening the rules for creating groups. Only allow grouping of counters that can be co-scheduled in the same context. This means for the same task and/or the same cpu.

This patch fixes a systematic crash in rapl_scale() due to an invalid pointer. The bug was introduced by commit: 89cbc767 ("x86: Replace __get_cpu_var uses") The fix is simple. Just put the parenthesis where it needs to be, i.e., around rapl_pmu. To my surprise, the compiler was not complaining about passing an integer instead of a pointer. Reported-by:

There were some issues about the uncore driver tried to access non-existing boxes, which caused boot crashes. These issues have been all fixed. But we should avoid boot failures if that ever happens again. This patch intends to prevent this kind of potential issues. It moves uncore_box_init out of driver initialization. The box will be initialized when it's first enabled. Signed-off-by:

Pull cgroup fix from Tejun Heo: "The lifetime rules of cgroup hierarchies always have been somewhat counter-intuitive and cgroup core tried to enforce that hierarchies w/o userland-visible usages must die in finite amount of time so that the controllers can be reused for other hierarchies; unfortunately, this can't be implemented reasonably for the memory controller - the kmemcg part doesn't have any way to forcefully drain the existing usages, leading to an interruptible hang if a following mount attempts to use the controller in any way. So, it seems like we're stuck with "hierarchies live on till they die whenever that may be" at least for now. This pretty much confines attaching controllers to hierarchies to before the hierarchies are actively used by making dynamic configurations post active usages unreliable. This has never been reliable and should be fine in practice given how cgroups are used. After the patch, hierarchies aren't killed if it isn't already drained. A following mount attempt of the same mount options will reuse the existing hierarchy. Mount attempts with differing options will fail w/ -EBUSY" * 'for-3.19-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: prevent mount hang due to memory controller lifetime

The OOM killing invocation does a lot of duplicative checks against the task's allocation context. Rework it to take advantage of the existing checks in the allocator slowpath. The OOM killer is invoked when the allocator is unable to reclaim any pages but the allocation has to keep looping. Instead of having a check for __GFP_NORETRY hidden in oom_gfp_allowed(), just move the OOM invocation to the true branch of should_alloc_retry(). The __GFP_FS check from oom_gfp_allowed() can then be moved into the OOM avoidance branch in __alloc_pages_may_oom(), along with the PF_DUMPCORE test. __alloc_pages_may_oom() can then signal to the caller whether the OOM killer was invoked, instead of requiring it to duplicate the order and high_zoneidx checks to guess this when deciding whether to continue.
