Merge tag 'trace-rtla-v7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull RTLA updates from Steven Rostedt:

- Remove unused function declarations

Some functions were removed in recent code consolidation 6.18, but
their prototypes were not removed from headers. Remove them.

- Set stop threshold after enabling instances

Prefer recording samples without stopping on them on the start of
tracing to stopping on samples that are never recorded. This fixes
flakiness of some RTLA tests and unifies behavior of sample
collection between tracefs mode and BPF mode.

- Consolidate usage help message implementation

RTLA tools (osnoise-top, osnoise-hist, timerlat-top, timerlat-hist)
each implement usage help individually. Move common logic between
them into a new function to reduce code duplication.

- Add BPF actions feature

Add option --bpf-action to attach a BPF program (passed as filename
of its ELF representation) to be executed via BPF tail call at
latency threshold.

- Consolidate command line option parsing

Each RTLA tool implements the parsing of command line options
individually. Now that we have a common structure for parameters,
unify the parsing of those options common among all four tools into
one function.

- De-duplicate cgroup common code

Two functions in utils.c, setting cgroup for comm and setting cgroup
for pid, duplicate code for constructing the cgroup path. Extract it
to a new helper function.

- String and error handling fixes and cleanups

There were several instances of unsafe string and error handling that
could cause invalid memory access; fix them. Also, remove a few
unused headers, update .gitignore, and deduplicate code.

rtla/tests: Run Test::Harness in verbose mode

Add -v flag to prove command to also print the names of tests that
succeeded, not only those that failed, to allow easier debugging of the
test suite.

Also, drop printing the option and value to stdout in
check_with_osnoise_options, which was a debugging print that was
accidentally left in the final commit, and which would be otherwise now
visible in make check output, as stdout is no longer suppressed.

Add a test that implements a BPF program writing to a test map, which
is attached to RTLA via --bpf-action to be executed on theshold
overflow.

A combination of --on-threshold shell with bpftool (which is always
present if BPF support is enabled) is used to check whether the BPF
program has executed successfully.

Add an example BPF action program that prints the measured latency to

If BPF skeleton support is unavailable or disabled, a warning will be
displayed when building the BPF action program example.

riscv patches for 6.15-rc1

* A bunch of fixes:
- We were missing a secondary mmu notifier call when flushing the tlb which is required for IOMMU
- Fix ftrace panics by saving the registers as expected by ftrace
- Fix a couple of stimecmp usage related to cpu hotplug
- Fix a bunch of issues in the misaligned probing handling

* Perf improvements:
- Introduce support for runtime constant improving perf of d_hash()
- Add support for huge pfnmaps to improve tlb utilization
- Use Zawrs to improve smp_cond_load8/16() used by the queued spinlocks

* Hwprobe additions:
- Add support for Zicntr and Zihpm
- Add support for Zaamo and Zalrsc
- Add support for bfloat16 extensiosn
- Add support for Zicbom (only enabling clean and flush, not inval for security reasons)

* Misc:
- Add a kernel parameter to bypass the misaligned speed probing since we can't rely on Zicclsm
