2021-07-15perf lzma: Close lzma stream on exitRiccardo Mancini
ASan reports memory leaks when running: # perf test "88: Check open filename arg using perf trace + vfs_getname" One of these is caused by the lzma stream never being closed inside lzma_decompress_to_file().

2021-07-15perf script: Fix memory 'threads' and 'cpus' leaks on exitRiccardo Mancini
ASan reports several memory leaks while running: # perf test "82: Use vfs_getname probe to get syscall args filenames" Two of these are caused by some refcounts not being decreased on perf-script exit, namely script.threads and script.cpus. This patch adds the missing __put calls in a new perf_script__exit function, which is called at the end of cmd_script. This patch concludes the fixes of all remaining memory leaks in perf test "82: Use vfs_getname probe to get syscall args filenames".

2021-07-14perf cs-etm: Split Coresight decode by aux recordsJames Clark
Populate the auxtrace queues using AUX records rather than whole auxtrace buffers so that the decoder is reset between each aux record. This is similar to the auxtrace_queues__process_index() -> auxtrace_queues__add_indexed_event() flow where perf_session__peek_event() is used to read AUXTRACE events out of random positions in the file based on the auxtrace index. But now we loop over all PERF_RECORD_AUX events instead of AUXTRACE buffers. For each PERF_RECORD_AUX event, we find the corresponding AUXTRACE buffer using the index, and add a fragment of that buffer to the auxtrace queues. No other changes to decoding were made, apart from populating the auxtrace queues. The result of decoding is identical to before, except in cases where decoding failed completely, due to not resetting the decoder. The reason for this change is because AUX records are emitted any time tracing is disabled, for example when the process is scheduled out. Because ETM was disabled and enabled again, the decoder also needs to be reset to force the search for a sync packet. Otherwise there would be fatal decoding errors. Testing ======= Testing was done with the following script, to diff the decoding results between the patched and un-patched versions of perf: #!/bin/bash set -ex $1 script -i $3 $4 > split.script $2 script -i $3 $4 > default.script diff split.script default.script | head -n 20 And it was run like this, with various itrace options depending on the quantity of synthesised events: compare.sh ./perf-patched ./perf-default perf-per-cpu-2-threads.data --itrace=i100000ns No changes in output were observed in the following scenarios: * Simple per-cpu perf record -e cs_etm/@tmc_etr0/u top * Per-thread, single thread perf record -e cs_etm/@tmc_etr0/u --per-thread ./threads_C * Per-thread multiple threads (but only one thread collected data): perf record -e cs_etm/@tmc_etr0/u --per-thread --pid 4596,4597 * Per-thread multiple threads (both threads collected data): perf record -e cs_etm/@tmc_etr0/u --per-thread --pid 4596,4597 * Per-cpu explicit threads: perf record -e cs_etm/@tmc_etr0/u --pid 853,854 * System-wide (per-cpu): perf record -e cs_etm/@tmc_etr0/u -a * No data collected (no aux buffers) Can happen with any command when run for a short period * Containing truncated records Can happen with any command * Containing aux records with 0 size Can happen with any command * Snapshot mode (various files with and without buffer wrap) perf record -e cs_etm/@tmc_etr0/u -a --snapshot Some differences were observed in the following scenario: * Snapshot mode (with duplicate buffers) perf record -e cs_etm/@tmc_etr0/u -a --snapshot Fewer samples are generated in snapshot mode if duplicate buffers were gathered because buffers with the same offset are now only added once. This gives different, but more correct results and no duplicate data is decoded any more.

2021-07-14tools headers: Remove broken definition of __LITTLE_ENDIANArnaldo Carvalho de Melo
The linux/kconfig.h file was copied from the kernel but the line where with the generated/autoconf.h include from where the CONFIG_ entries would come from was deleted, as tools/ build system don't create that file, so we ended up always defining just __LITTLE_ENDIAN as CONFIG_CPU_BIG_ENDIAN was nowhere to be found. This in turn ended up breaking the build in some systems where __LITTLE_ENDIAN was already defined, such as the androind NDK. So just ditch that block that depends on the CONFIG_CPU_BIG_ENDIAN define. The kconfig.h file was copied just to get IS_ENABLED() and a 'make -C tools/all' doesn't breaks with this removal.

On a hybrid platform, by default 'perf stat' aggregates and reports the event counts per PMU. For example, # perf stat -e cycles -a true Performance counter stats for 'system wide': 1,400,445 cpu_core/cycles/ 680,881 cpu_atom/cycles/ 0.001770773 seconds time elapsed But for uncore events that's not a suitable method. Uncore has nothing to do with hybrid. So for uncore events, we aggregate event counts from all PMUs and report the counts without PMUs. Before: # perf stat -e arb/event=0x81,umask=0x1/,arb/event=0x84,umask=0x1/ -a true Performance counter stats for 'system wide': 2,058 uncore_arb_0/event=0x81,umask=0x1/ 2,028 uncore_arb_1/event=0x81,umask=0x1/ 0 uncore_arb_0/event=0x84,umask=0x1/ 0 uncore_arb_1/event=0x84,umask=0x1/ 0.000614498 seconds time elapsed After: # perf stat -e arb/event=0x81,umask=0x1/,arb/event=0x84,umask=0x1/ -a true Performance counter stats for 'system wide': 3,996 arb/event=0x81,umask=0x1/ 0 arb/event=0x84,umask=0x1/ 0.000630046 seconds time elapsed Of course, we also keep the '--no-merge' working for uncore events. # perf stat -e arb/event=0x81,umask=0x1/,arb/event=0x84,umask=0x1/ --no-merge true Performance counter stats for 'system wide': 1,952 uncore_arb_0/event=0x81,umask=0x1/ 1,921 uncore_arb_1/event=0x81,umask=0x1/ 0 uncore_arb_0/event=0x84,umask=0x1/ 0 uncore_arb_1/event=0x84,umask=0x1/ 0.000575536 seconds time elapsed Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Kan Liang <kan.liang@intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: https://lore.kernel.org/r/20210707055652.962-1-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

On hybrid platform, such as Alderlake, if atom CPUs are offlined, the kernel still exports the sysfs path '/sys/devices/cpu_atom/' for 'cpu_atom' pmu but the file '/sys/devices/cpu_atom/cpus' is empty, which indicates this is an invalid pmu.

The cpu_atom events are still displayed even if atom CPUs are offlined.

2021-07-11mm/rmap: fix old bug: munlocking THP missed other mlocksHugh Dickins
The kernel recovers in due course from missing Mlocked pages: but there was no point in calling page_mlock() (formerly known as try_to_munlock()) on a THP, because nothing got done even when it was found to be mapped in another VM_LOCKED vma. It's true that we need to be careful: Mlocked accounting of pte-mapped THPs is too difficult (so consistently avoided); but Mlocked accounting of only-pmd-mapped THPs is supposed to work, even when multiple mappings are mlocked and munlocked or munmapped. Refine the tests. There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so page_mlock_one() does not even have to worry about that complication. (I said the kernel recovers: but would page reclaim be likely to split THP before rediscovering that it's VM_LOCKED? I've not followed that up) Fixes: 9a73f61bdb8a ("thp, mlock: do not mlock PTE-mapped file huge pages") Signed-off-by: Hugh Dickins <hughd@google.com> Reviewed-by: Shakeel Butt <shakeelb@google.com> Acked-by: Kirill A.
