       "Apologies for the _extremely_ late pull request here, but we had a
        'perf' (i.e. CPU PMU) regression on the Apple M1 reported on Wednesday
        [1] which was introduced by bd275681 ("perf: Rewrite core context
        handling") during the merge window.
      
        Mark and I looked into this and noticed an additional problem caused
        by the same patch, where the 'CHAIN' event (used to combine two
        adjacent 32-bit counters into a single 64-bit counter) was not being
        filtered correctly. Mark posted a series on Thursday [2] which
        addresses both of these regressions and I queued it the same day.
      
        The changes are small, self-contained and have been confirmed to fix
        the original regression.

      arm64: perf: reject CHAIN events at creation time · 853e2dac
      Mark Rutland authored
      Currently it's possible for a user to open CHAIN events arbitrarily,
      which we previously tried to rule out in commit:
      
        ca2b4972 ("arm64: perf: Reject stand-alone CHAIN events for PMUv3")
      
      Which allowed the events to be opened, but prevented them from being
      scheduled by by using an arm_pmu::filter_match hook to reject the
      relevant events.
      
      The CHAIN event filtering in the arm_pmu::filter_match hook was silently
      removed in commit:
      
        bd275681 ("perf: Rewrite core context handling")
      
      As a result, it's now possible for users to open CHAIN events, and for
      these to be installed arbitrarily.
      
      Fix this by rejecting CHAIN events at creation time. This avoids the
      creation of events which will never count, and doesn't require using the
      dynamic filtering.
      
      Attempting to open a CHAIN event (0x1e) will now be rejected:
      
      | # ./perf stat -e armv8_pmuv3/config=0x1e/ ls
      | perf
      |
      |  Performance counter stats for 'ls':
      |
      |    <not supported>      armv8_pmuv3/config=0x1e/

      |        0.000000000 seconds user
      |        0.002294000 seconds sys
      
      Other events (e.g. CPU_CYCLES / 0x11) will open as usual:
      
      | # ./perf stat -e armv8_pmuv3/config=0x11/ ls
      | perf
      |
      |  Performance counter stats for 'ls':

      arm_pmu: fix event CPU filtering · 61d03862
      Mark Rutland authored
      Janne reports that perf has been broken on Apple M1 as of commit:
      
        bd275681 ("perf: Rewrite core context handling")
      
      That commit replaced the pmu::filter_match() callback with
      pmu::filter(), whose return value has the opposite polarity, with true
      implying events should be ignored rather than scheduled. While an
      attempt was made to update the logic in armv8pmu_filter() and
      armpmu_filter() accordingly, the return value remains inverted in a
      couple of cases:
      
      * If the arm_pmu does not have an arm_pmu::filter() callback,
        armpmu_filter() will always return whether the CPU is supported rather
        than whether the CPU is not supported.
      
        As a result, the perf core will not schedule events on supported CPUs,
        resulting in a loss of events. Additionally, the perf core will
        attempt to schedule events on unsupported CPUs, but this will be
        rejected by armpmu_add(), which may result in a loss of events from
        other PMUs on those unsupported CPUs.
      
      * If the arm_pmu does have an arm_pmu::filter() callback, and
        armpmu_filter() is called on a CPU which is not supported by the
        arm_pmu, armpmu_filter() will return false rather than true.
      
        As a result, the perf core will attempt to schedule events on
        unsupported CPUs, but this will be rejected by armpmu_add(), which may
        result in a loss of events from other PMUs on those unsupported CPUs.
      
      This means a loss of events can be seen with any arm_pmu driver, but
      with the ARMv8 PMUv3 driver (which is the only arm_pmu driver with an
      arm_pmu::filter() callback) the event loss will be more limited and may
      go unnoticed, which is how this issue evaded testing so far.
      
      Fix the CPU filtering by performing this consistently in
      armpmu_filter(), and remove the redundant arm_pmu::filter() callback and
      armv8pmu_filter() implementation.
      
      Commit bd275681 also silently removed the CHAIN event filtering from
      armv8pmu_filter(), which will be addressed by a separate patch without
      using the filter callback.

       "One more last minute patch for v6.2 updating the parsing of the newly
        added spi-cs-setup-delay-ns.
      
        It's been pointed out that due to the way DT parsing works the change
        in property size is ABI visible so let's not let a release go out
        without it being fixed. The change got split from some earlier ABI
        related fixes to the property since the first version sent had a build
        error"

      The uuid code is very low maintainance now that the major overhaul
      has completed, and doesn't need it's own tree.  All the recent work
      has been done by Andy who'd like to stay on as a reviewer without an
      explicit tree.

      This code has been stale for years and I have no way to test it.
