Reusing the existing --total-cycles option to display the branch
counters. Add a new PERF_HPP_REPORT__BLOCK_BRANCH_COUNTER to display
the logged branch counter events. They are shown right after all the
cycle-related annotations.
Extend the 'struct block_info' to store and pass the branch counter
related information.
The annotation_br_cntr_entry() is to print the histogram of each branch
counter event. If the number of logged events is less than 4, the exact
number of the abbr name is printed. Otherwise, using '+' to stands for
more than 3 events.
Assume the number of logged events is less than 4.
The annotation_br_cntr_abbr_list() prints the branch counter's
abbreviation list. Press 'B' to display the list in the TUI mode.
$ perf record -e "{branch-instructions:ppp,branch-misses}:S" -j any,counter

There could be several branch counter events. If perf tool output the
result via the format "event name + a number", the line could be very
long and hard to read.
An abbreviation is introduced to replace the full event name in the
display. The abbreviation starts from 'A' to 'Z9', which can support
up to 286 events. The same abbreviation will be assigned if the same
events are found in the evlist. The next patch will utilize the
abbreviation name to show the branch counter events in the output.

When annotating a basic block, it's useful to display the occurrences
of other events in the block.
The branch counter feature is only available for newer Intel platforms.
So a dedicated option to display the branch counters is not introduced.
Reuse the existing --total-cycles option, which triggers the annotation
of a basic block and displays the cycle-related annotation.
When the branch counters information is available, the branch counters
are automatically appended after all the cycle-related annotation.
Accounting the branch counters as well when accounting the cycles in
hist__account_cycles().
In 'struct annotated_branch', introduce a br_cntr array to save the
accumulation of each branch counter.
In a sample, all the branch counters for a branch are saved in a u64
space.
Because the saturation of a branch counter is small, e.g., for Intel
Sierra Forest, the saturation is only 3.
Add ANNOTATION__BR_CNTR_SATURATED_FLAG to indicate if a branch counter
once saturated. That can be used to indicate a potential event lost
because of the saturation.

The branch counters logging (A.K.A LBR event logging) introduces a
per-counter indication of precise event occurrences in LBRs. The kernel
only dumps the number of occurrences into a record. The perf tool has
to map the number to the corresponding event.
Add evlist__update_br_cntr() to go through the evlist to pick the
events that are configured to be logged. Assign a logical idx to track
them, and add the total number of the events in the leader event.
The total number will be used to allocate the space to save the branch
counters for a block. The logical idx will be used to locate the
corresponding event quickly in the following patches.
It only needs to iterate the evlist once. The
evsel__has_branch_counters() is also optimized.

A false overflow warning is triggered if a sample doesn't have any LBRs
recorded and the branch counters feature is enabled.
The current code does OVERFLOW_CHECK_u64() at the very beginning when
reading the information of branch counters. It assumes that there is at
least one LBR in the PEBS record. But it is a valid case that 0 LBR is
recorded especially in a high context switch.
Remove the OVERFLOW_CHECK_u64(). The later OVERFLOW_CHECK() should be
good enough to check the overflow when reading the information of the
branch counters.

With the symbol_conf.event_group, the 'perf report' should only report the
block information of the leader event in a group.
However, the current implementation retrieves the next event's block
information, rather than the next group leader's block information.
Make sure the index is updated even if the event is skipped.

Some servers have limitations on the number of CPUs a given guest OS
can use. In my earlier experience, such limitations have been at least
half of the host's CPUs, but in a recent example, this limit is less
than 40%. This commit therefore adds a --guest-cpu-limit argument that
allows such low limits to be made known to torture.sh.

On little-endian systems, doing subtraction after htons()
leads to interesting results:
Given:
MAGIC_BYTES = 123 = 0x007B aka. in big endian: 0x7B00 = 31488
sizeof(struct iphdr) = 20
Before this patch:
__bpf_constant_htons(MAGIC_BYTES) - sizeof(struct iphdr) = 0x7AEC
0x7AEC = htons(0xEC7A) = htons(60538)
So these were outer IP packets with a total length of 123 bytes,
containing an inner IP packet with a total length of 60538 bytes.
After this patch:
__bpf_constant_htons(MAGIC_BYTES - sizeof(struct iphdr)) = htons(103)
Now these packets are outer IP packets with a total length of 123 bytes,
containing an inner IP packet with a total length of 103 bytes.

Add MTL metric JSON file for TMA4.8. Some of the metrics' formulas use TPEBS
retire_latency in MTL.
This also includes lated E-Core TMA3.6 changes.

retire latency value for a metric.
When retire_latency value is used in a metric formula, evsel would fork
a 'perf record' process with "-e" and "-W" options. 'perf record' will
collect required retire_latency values in parallel while 'perf stat' is
collecting counting values.
At the point of time that 'perf stat' stops counting, evsel would stop
'perf record' by sending sigterm signal to 'perf record' process.
Sampled data will be processed to get retire latency value. Another
thread is required to synchronize between 'perf stat' and 'perf record'
when we pass data through pipe.
Retire_latency evsel is not opened for 'perf stat' so that there is no
counter wasted on it. This commit includes code suggested by Namhyung to
adjust reading size for groups that include retire_latency evsels.
In current :R parsing implementation, the parser would recognize events
with retire_latency modifier and insert them into the evlist like a
normal event. Ideally, we need to avoid counting these events.
In this commit, at the time when a retire_latency evsel is read, set the
retire latency value processed from the sampled data to count value.
This sampled retire latency value will be used for metric calculation
and final event count print out. No special metric calculation and event
print out code required for retire_latency events.

Add a test to verify that userspace can't change a vCPU's x2APIC ID by
abusing KVM_SET_LAPIC. KVM models the x2APIC ID (and x2APIC LDR) as
readonly, and silently ignores userspace attempts to change the x2APIC ID
for backwards compatibility.

git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 fixes for 6.11, round #1
- Use kvfree() for the kvmalloc'd nested MMUs array
- Set of fixes to address warnings in W=1 builds
- Make KVM depend on assembler support for ARMv8.4
- Fix for vgic-debug interface for VMs without LPIs
- Actually check ID_AA64MMFR3_EL1.S1PIE in get-reg-list selftest
- Minor code / comment cleanups for configuring PAuth traps
- Take kvm->arch.config_lock to prevent destruction / initialization
race for a vCPU's CPUIF which may lead to a UAF
|

A selftest is added such that without the previous patch,
a crash can happen. With the previous patch, the test can
run successfully. The new test is written in a way which
mimics original crash case:
main_prog
static_prog_1
static_prog_2
where static_prog_1 has different paths to static_prog_2
and some path has stack allocated and some other path
does not. A stacksafe() checking in static_prog_2()
triggered the crash.

Add tests that exercise full 16 bits of NH weight.
To test the 255:65535, it is necessary to run more packets than for the
other tests. On a debug kernel, the test can take up to a minute, therefore
avoid the test when KSFT_MACHINE_SLOW.

In the context of an offloaded datapath, it may take a while for the ip

Reduce scope of build_id__mark_dso_hit_ops() to the scope of function
perf_session__list_build_ids, its only use, and use perf_tool__init()
for the default values. Move perf_event__exit_del_thread() to event.[ch]
so it can be used in builtin-buildid-list.c.

Reduce the scope of the tool from global/static to just that of the
cmd_kmem function where the session is scoped. Use the perf_tool__init()
to initialize default values.
