https://github.com/intel/perfmon
The metrics are unchanged but the formulas differ due to parentheses,
use of exponents and removal of redundant operations like "* 1". The
order of metrics varies as TMA metrics are first converted and then
removed if perfmon versions are found. The events are updated with
fixes to uncore events and improved descriptions. The formatting
changes increase consistency across the json files.

Update the broadwellde metrics and events using the new tooling from:
https://github.com/intel/perfmon
The metrics vary as tma_false_sharing, MEM_Parallel_Requests and
MEM_Request_Latency are explicitly dropped from having missing events:
https://github.com/captain5050/perfmon/blob/main/scripts/create_perf_json.py#L934
The formulas also differ due to parentheses, use of exponents and
removal of redundant operations like "* 1". The events are unchanged
but unused json values are removed and implicit umasks of 0 are
dropped. This increases consistency across the json files.
mapfile.csv's version number is set to match that in the perfmon

We test metrics with fake events with fake values. The fake values may
yield division by zero and so we count both up and down to try to
avoid this. Unfortunately this isn't sufficient for some metrics and
so don't fail the test for them.
Add the metric name to debug output.

The sort_entry->cmp() will be called for eventy sample data to find a
matching entry. When it has 'srcline' sort key, that means it needs to
call addr2line or libbfd everytime.
This is not optimal because many samples will have same address and it
just can call addr2line once. So postpone the actual srcline check to
the sort_entry->collpase() and compare addresses in ->cmp().
Also it needs to add ->init() callback to make sure it has srcline info.
If a sample has a unique data, chances are the entry can be sorted out
by other (previous) keys and callbacks in sort_srcline never called.

In __hists__insert_output_entry(), it calls fmt->sort() for dynamic
entries with NULL to update column width for tracepoint fields.
But it's a hacky abuse of the sort callback, better to have a proper
callback for that. I'll add more use cases later.

Parametrized events are not only a powerpc domain. They occur on other
platforms too (e.g. aarch64). They should be ignored in this testcase,
since proper setup of the parameters is out of scope of this script.
Let's not filter them out by PMU name, but rather based on the fact that
they expect a parameter.

The -Y/--type-filter option is to filter the result for specific lock
types only. It can accept comma-separated values. Note that it would
accept type names like one in the output. spinlock, mutex, rwsem:R and
so on.
For RW-variant lock types, it converts the name to the both variants.
In other words, "rwsem" is same as "rwsem:R,rwsem:W". Also note that
"mutex" has two different encoding - one for sleeping wait, another for
optimistic spinning. Add "mutex-spin" entry for the lock_type_table so
that we can add it for "mutex" under the table.

Make get_type_flag() return UINT_MAX for error instad of -1UL, as that
function returns 'unsigned int' and we store the value on a 'unsigned
int' 'flags' variable which makes clang unhappy:

When perf uses quiet mode, perf_quiet_option() sets the 'debug_peo_args'
variable to -1, and display_attr() incorrectly determines the value of
'debug_peo_args'. As a result, unexpected information is displayed.

86bdf3ebcf ("KVM: Support dirty ring in conjunction with bitmap")
That just rebuilds perf, as these patches don't add any new KVM ioctl to
be harvested for the the 'perf trace' ioctl syscall argument
beautifiers.
This is also by now used by tools/testing/selftests/kvm/, a simple test
build didn't succeed, but for another reason:
lib/kvm_util.c: In function ‘vm_enable_dirty_ring’:
lib/kvm_util.c:125:30: error: ‘KVM_CAP_DIRTY_LOG_RING_ACQ_REL’ undeclared (first use in this function); did you mean ‘KVM_CAP_DIRTY_LOG_RING’?
125 | if (vm_check_cap(vm, KVM_CAP_DIRTY_LOG_RING_ACQ_REL))
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| KVM_CAP_DIRTY_LOG_RING
I'll send a separate patch for that.

Pull more nfsd updates from Chuck Lever:
"This contains a number of crasher fixes that were not ready for the
initial pull request last week.
In particular, Jeff's patch attempts to address reference count
underflows in NFSD's filecache, which have been very difficult to
track down because there is no reliable reproducer.
Common failure modes:
https://bugzilla.kernel.org/show_bug.cgi?id=216691#c11https://bugzilla.kernel.org/show_bug.cgi?id=216674#c6https://bugzilla.redhat.com/show_bug.cgi?id=2138605
The race windows were found by inspection and the clean-ups appear
sensible and pass regression testing, so we include them here in the
hope that they address the problem. However we remain vigilant because
we don't have 100% certainty yet that the problem is fully addressed.
Summary:
- Address numerous reports of refcount underflows in NFSD's filecache
- Address a UAF in callback setup error handling
- Address a UAF during server-to-server copy"

- Enable objtool to be built on powerpc to generate mcount locations.
- Use a temporary mm for code patching with the Radix MMU, so the writable mapping is
restricted to the patching CPU.
- Add an option to build the 64-bit big-endian kernel with the ELFv2 ABI.
- Sanitise user registers on interrupt entry on 64-bit Book3S.

Merge tag 'powerpc-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
- Add powerpc qspinlock implementation optimised for large system
scalability and paravirt. See the merge message for more details
- Enable objtool to be built on powerpc to generate mcount locations
- Use a temporary mm for code patching with the Radix MMU, so the
writable mapping is restricted to the patching CPU
- Add an option to build the 64-bit big-endian kernel with the ELFv2
ABI
- Sanitise user registers on interrupt entry on 64-bit Book3S
- Many other small features and fixes

- Two minor feature patches which were awkwardly dependent on mm-nonmm.
I need to set up a new branch to handle such things.
