perf addr2line.c: Rename a2l_style to cmd_a2l_style
The a2l_style is only relevant to the command line version, so rename to make this clearer.

perf addr2line: Add a libdw implementation
Add an implementation of addr2line that uses libdw.
Other addr2line implementations are slow, particularly in the case of
forking addr2line.
Add an implementation that caches the libdw information in the dso and
uses it to find the file and line number information.
Inline information is supported but because cu_walk_functions_at visits
the leaf function last add a inline_list__append_tail to reverse the
lists order.
Committer testing:
# perf probe -x ~/bin/perf libdw__addr2line
Added new event:
probe_perf:libdw_addr2line (on libdw__addr2line in /home/acme/bin/perf)
You can now use it in all perf tools, such as:
perf record -e probe_perf:libdw_addr2line -aR sleep 1
#
# perf stat -e probe_perf:libdw_addr2line perf report -f --dso perf --stdio -s srcfile,srcline
# To display the perf.data header info, please use --header/--header-only options.

#
Adding probes to the other addr2line implementations (llvm__addr2line,
libbfd__addr2line and cmd__addr2line) I noticed some fallbacks to the
llvm one:
Performance counter stats for 'perf report -f --dso perf --stdio -s srcfile,srcline':
44 probe_perf:libdw_addr2line
23 probe_perf:llvm_addr2line
0 probe_perf:libbfd_addr2line
0 probe_perf:cmd_addr2line
Something to investigate further, but at least we don't fallback to the
cmd based one :-)

perf test stat tests: Fix for virtualized machines
On s390 'perf test's 'perf stat tests', subtest test_hybrid fails for
z/VM systems. The root cause is this statement:
$(perf stat -a -- sleep 0.1 2>&1 |\
grep -E "/cpu-cycles/[uH]*| cpu-cycles[:uH]* -c)
The 'perf stat' output on a s390 z/VM system is
# perf stat -a -- sleep 0.1 2>&1
Performance counter stats for 'system wide':
56 context-switches # 46.3 cs/sec cs_per_second
1,210.41 msec cpu-clock # 11.9 CPUs CPUs_utilized
12 cpu-migrations # 9.9 migrations/sec ...
81 page-faults # 66.9 faults/sec ...
0.100891009 seconds time elapsed
The grep command does not match any single line and exits with error
code 1.
As the bash script is executed with 'set -e', it aborts with the first
error code being non-zero.
Fix this and use 'wc -l' to count matching lines instead of 'grep ... -c'.
Output before:
# perf test 102

perf build: Skip nondistro build test if libbfd is old
Non distro builds now require a new version of libbfd, so skip the test if the library is too old. The grep test isn't a strong as the feature test in test-libbfd-threadsafe.c, but there seems to be precedent for feature testing this way here and it's good enough for the build-test rule. If the function exists but returns an error it will be picked up by the feature test when attempting the build.

perf build: Remove FEATURE_CHECK_LDFLAGS-disassembler-{four-args,init-styled} setting
As the building mechanism is now able to retry detection with different
combinations of linking flags, setting FEATURE_CHECK_LDFLAGS-disassembler-four-args
and FEATURE_CHECK_LDFLAGS-disassembler-init-styled is not necessary anymore,
so remove it.

Use the same technique to find the set of bfd-related libraries to link as in:

perf test java symbol: Additional libperf-jvmti.so path check
If perf is built into an output directory then so is libperf-jvmti.so. If `perf test` is run from that directory then PWD needn't also be that directory meaning libperf-jvmti.so won't be found and the test skipped. Add an additional check for libperf-jvmti.so in the same directory as the perf binary for this case, this avoids the test skipping.

of: unittest: Fix memory leak in unittest_data_add()
In unittest_data_add(), if of_resolve_phandles() fails, the allocated
unittest_data is not freed, leading to a memory leak.
Fix this by using scope-based cleanup helper __free(kfree) for automatic
resource cleanup. This ensures unittest_data is automatically freed when
it goes out of scope in error paths.
For the success path, use retain_and_null_ptr() to transfer ownership
of the memory to the device tree and prevent double freeing.

kselftest/harness: Use helper to avoid zero-size memset warning
When building kselftests with a toolchain that enables source fortification (e.g., Android's build environment, which uses -D_FORTIFY_SOURCE=3), a build failure occurs in tests that use an empty FIXTURE(). The root cause is that an empty fixture struct results in `sizeof(self_private)` evaluating to 0. The compiler's fortification checks then detect the `memset()` call with a compile-time constant size of 0, issuing a `-Wuser-defined-warnings` which is promoted to an error by `-Werror`. An initial attempt to guard the call with `if (sizeof(self_private) > 0)` was insufficient. The compiler's static analysis is aggressive enough to flag the `memset(..., 0)` pattern before evaluating the conditional, thus still triggering the error. To resolve this robustly, this change introduces a `static inline` helper function, `__kselftest_memset_safe()`. This function wraps the size check and the `memset()` call. By replacing the direct `memset()` in the `__TEST_F_IMPL` macro with a call to this helper, we create an abstraction boundary. This prevents the compiler's static analyzer from "seeing" the problematic pattern at the macro expansion site, resolving the build failure. Build Context: Compiler: Android (14488419, +pgo, +bolt, +lto, +mlgo, based on r584948) clang version 22.0.0 (https://android.googlesource.com/toolchain/llvm-project 2d65e4108033380e6fe8e08b1f1826cd2bfb0c99) Relevant Options: -O2 -Wall -Werror -D_FORTIFY_SOURCE=3 -target i686-linux-android10000 Test: m kselftest_futex_futex_requeue_pi Removed Gerrit Change-Id Shuah Khan <skhan@linuxfoundation.org> Link: https://lore.kernel.org/r/20251224084120.249417-1-wakel@google.com Signed-off-by: Wake Liu <wakel@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> |

selftests/ftrace: Test toplevel-enable for instance
'available_events' is actually not required by 'test.d/event/toplevel-enable.tc' and its Existence has been tested in 'test.d/00basic/basic4.tc'. So the require of 'available_events' can be dropped and then we can add 'instance' flag to test 'test.d/event/toplevel-enable.tc' for instance. Test result show as below: # ./ftracetest test.d/event/toplevel-enable.tc === Ftrace unit tests === [1] event tracing - enable/disable with top level files [PASS] [2] (instance) event tracing - enable/disable with top level files [PASS] # of passed: 2 # of failed: 0 # of unresolved: 0 # of untested: 0 # of unsupported: 0 # of xfailed: 0 # of undefined(test bug): 0 Link: https://lore.kernel.org/r/20230509203659.1173917-1-zhengyejian1@huawei.com Signed-off-by: Zheng Yejian <zhengyejian1@huawei.com> Acked-by: Steven Rostedt (Google) <rostedt@goodmis.org> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org> |

selftests/ftrace: traceonoff_triggers: strip off names
The func_traceonoff_triggers.tc sometimes goes to fail
on my board, Kunpeng-920.
[root@localhost]# ./ftracetest ./test.d/ftrace/func_traceonoff_triggers.tc -l fail.log
=== Ftrace unit tests ===
[1] ftrace - test for function traceon/off triggers [FAIL]
[2] (instance) ftrace - test for function traceon/off triggers [UNSUPPORTED]
I look up the log, and it shows that the md5sum is different between csum1 and csum2.
++ cnt=611
++ sleep .1
+++ cnt_trace
+++ grep -v '^#' trace
+++ wc -l
++ cnt2=611
++ '[' 611 -ne 611 ']'
+++ cat tracing_on
++ on=0
++ '[' 0 '!=' 0 ']'
+++ md5sum trace
++ csum1='76896aa74362fff66a6a5f3cf8a8a500 trace'
++ sleep .1
+++ md5sum trace
++ csum2='ee8625a21c058818fc26e45c1ed3f6de trace'
++ '[' '76896aa74362fff66a6a5f3cf8a8a500 trace' '!=' 'ee8625a21c058818fc26e45c1ed3f6de trace' ']'
++ fail 'Tracing file is still changing'
++ echo Tracing file is still changing
Tracing file is still changing
++ exit_fail
++ exit 1
So I directly dump the trace file before md5sum, the diff shows that:
[root@localhost]# diff trace_1.log trace_2.log -y --suppress-common-lines
dockerd-12285 [036] d.... 18385.510290: sched_stat | <...>-12285 [036] d.... 18385.510290: sched_stat

And we can see that <...> filed be filled with names.
We can strip off the names there to fix that.
After strip off the names:

VFIO fixes for v6.19-rc4
- Restrict ROM access to dword to resolve a regression introduced
with qword access seen on some Intel NICs. Update VGA region
access to the same given lack of precedent for 64-bit users.
(Kevin Tian)
- Fix missing .get_region_info_caps callback in the xe-vfio-pci
variant driver due to integration through the DRM tree.
(Michal Wajdeczko)
- Add aligned 64-bit access macros to tools/include/linux/types.h,
allowing removal of uapi/linux/type.h includes from various
vfio selftest, resolving redefinition warnings for integration
with KVM selftests. (David Matlack)
- Fix error path memory leak in pds-vfio-pci variant driver.
(Zilin Guan)
- Fix error path use-after-free in xe-vfio-pci variant driver.
