2022-02-23RDMA/mlx5: Fix the flow of a miss in the allocation of a cache ODP MRAharon Landau1-0/+2
When an ODP MR cache entry is empty and trying to allocate it, increment the ent->miss counter and call to queue_adjust_cache_locked() to verify the entry is balanced.

2022-02-16RDMA/rxe: Revert changes from irqsave to bh locksBob Pearson6-48/+69
A previous patch replaced all irqsave locks in rxe with bh locks. This ran into problems because rdmacm has a bad habit of calling rdma verbs APIs while disabling irqs. This is not allowed during spin_unlock_bh() causing programs that use rdmacm to fail. This patch reverts the changes to locks that had this problem or got dragged into the same mess. After this patch blktests/check -q srp now runs correctly.

2022-01-23ftrace: Fix assuming build time sort works for s390Steven Rostedt (Google)2-3/+10
To speed up the boot process, as mcount_loc needs to be sorted for ftrace to work properly, sorting it at build time is more efficient than boot up and can save milliseconds of time. Unfortunately, this change broke s390 as it will modify the mcount_loc location after the sorting takes place and will put back the unsorted locations. Since the sorting is skipped at boot up if it is believed that it was sorted at run time, ftrace can crash as its algorithms are dependent on the list being sorted. Add a new config BUILDTIME_MCOUNT_SORT that is set when BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine if sorting should take place at boot up.

2022-01-22perf test: Add parse-events test for aliases with hyphensJohn Garry2-9/+82
Add a test which allows us to test parsing an event alias with hyphens. Since these events typically do not exist on most host systems, add the alias to the fake pmu. Function perf_pmu__test_parse_init() has terms added to match known test aliases.

2022-01-22perf test: Add pmu-events test for aliases with hyphensJohn Garry2-0/+48
Add a test for aliases with hyphens in the name to ensure that the pmu-events tables are as expects. There should be no reason why these sort of aliases would be treated differently, but no harm in checking.

2022-01-22perf parse-events: Support event alias in form foo-bar-bazJohn Garry4-4/+41
Event aliasing for events whose name in the form foo-bar-baz is not supported, while foo-bar, foo_bar_baz, and other combinations are, i.e. two hyphens are not supported. The HiSilicon D06 platform has events in such form: $ ./perf list sdir-home-migrate List of pre-defined events (to be used in -e): uncore hha: sdir-home-migrate [Unit: hisi_sccl,hha] $ sudo ./perf stat -e sdir-home-migrate event syntax error: 'sdir-home-migrate' \___ parser error Run 'perf list' for a list of valid events Usage: perf stat [<options>] [<command>] -e, --event <event>event selector. use 'perf list' to list available events To support, add an extra PMU event symbol type for "baz", and add a new rule in the bison file.

2022-01-22perf evsel: Override attr->sample_period for non-libpfm4 eventsGerman Gomez1-8/+17
A previous patch preventing "attr->sample_period" values from being overridden in pfm events changed a related behaviour in arm-spe. Before said patch: perf record -c 10000 -e arm_spe_0// -- sleep 1 Would yield an SPE event with period=10000. After the patch, the period in "-c 10000" was being ignored because the arm-spe code initializes sample_period to a non-zero value. This patch restores the previous behaviour for non-libpfm4 events.
