perf test: Support the ins_lat check in the X86 specific testThe ins_lat of PERF_SAMPLE_WEIGHT_STRUCT stands for the instructionlatency, which is only available for X86. Add a X86 specific test forthe ins_lat and PERF_SAMPLE_WEIGHT_STRUCT type.The test__x86_sample_parsing() uses the same way as thetest__sample_parsing() to verify a sample type. Since the ins_lat andPERF_SAMPLE_WEIGHT_STRUCT are the only X86 specific sample type for now,the test__x86_sample_parsing() only verify the PERF_SAMPLE_WEIGHT_STRUCTtype.

perf tests: Add breakpoint modify testsAdding to tests that aims on kernel breakpoint modification bugs.First test creates HW breakpoint, tries to change it and checks it wasproperly changed. It aims on kernel issue that prevents HW breakpoint tobe changed via ptrace interface.The first test forks, the child sets itself as ptrace tracee and waitsin signal for parent to trace it, then it calls bp_1 and quits.The parent does following steps: - creates a new breakpoint (id 0) for bp_2 function - changes that breakpoint to bp_1 function - waits for the breakpoint to hit and checks it has proper rip of bp_1 functionThis test aims on an issue in kernel preventing to change disabledbreakpointsSecond test mimics the first one except for few stepsin the parent: - creates a new breakpoint (id 0) for bp_1 function - changes that breakpoint to bogus (-1) address - waits for the breakpoint to hit and checks it has proper rip of bp_1 functionThis test aims on an issue in kernel disabling enabledbreakpoint after unsuccesful change.Committer testing: # uname -a Linux jouet 4.18.0-rc8-00002-g1236568ee3cb #12 SMP Tue Aug 7 14:08:26 -03 2018 x86_64 x86_64 x86_64 GNU/Linux # perf test -v "bp modify" 62: x86 bp modify : --- start --- test child forked, pid 25671 in bp_1 tracee exited prematurely 2 FAILED arch/x86/tests/bp-modify.c:209 modify test 1 failed test child finished with -1 ---- end ---- x86 bp modify: FAILED! #Signed-off-by: Jiri Olsa Tested-by: Arnaldo Carvalho de Melo Cc: Alexander Shishkin Cc: David Ahern Cc: Milind Chabbi Cc: Namhyung Kim Cc: Oleg Nesterov Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/20180827091228.2878-2-jolsa@kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/arch/x86/tests/Build

035827e9 - perf tests: Add Intel CQM test

Mon, 05 Oct 2015 14:40:21 +0000

perf tests: Add Intel CQM testPeter reports that it's possible to trigger a WARN_ON_ONCE() in theIntel CQM code by combining a hardware event and an Intel CQM(software) event into a group. Unfortunately, the perf tools are notable to create this bundle and we need to manually construct a testcase.For posterity, record Peter's proof of concept test case in tools/perfso that it presents a model for how we can perform architecturespecific tests, or "arch tests", in perf in the future.The particular issue triggered in the test case is that when thecounter for the hardware event overflows and triggers a PMI we'll readboth the hardware event and the software event counters.Unfortunately, for CQM that involves performing an IPI to read the CQMevent counters on all sockets, which in NMI context triggers theWARN_ON_ONCE().Reported-by: Peter Zijlstra Signed-off-by: Matt Fleming Cc: Adrian Hunter Cc: Andi Kleen Cc: Fenghua Yu Cc: Jiri Olsa Cc: Kanaka Juvva Cc: Vikas Shivappa Cc: Vince Weaver Link: http://lkml.kernel.org/r/1437490509-15373-1-git-send-email-matt@codeblueprint.co.ukLink: http://lkml.kernel.org/n/tip-3p4ra0u8vzm7m289a1m799kf@git.kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/arch/x86/tests/Build

perf tests: Move x86 tests into arch directoryMove out the x86-specific tests into tools/perf/arch/x86/tests anddefine an 'arch_tests' array, which is the list of tests that only applyto the build architecture.We can also now begin to get rid of some of the #ifdef code that ispresent in the generic perf tests.Signed-off-by: Matt Fleming Cc: Adrian Hunter Cc: Andi Kleen Cc: Fenghua Yu Cc: Jiri Olsa Cc: Kanaka Juvva Cc: Peter Zijlstra Cc: Vikas Shivappa Cc: Vince Weaver Link: http://lkml.kernel.org/n/tip-9s68h4ptg06ah0lgnjz55mqn@git.kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/arch/x86/tests/Build

perf tests: Add arch testsTests that only make sense for some architectures currently live inthe same place as the generic tests. Move out the x86-specific testsinto tools/perf/arch/x86/tests and define an 'arch_tests' array, whichis the list of tests that only apply to the build architecture.The main idea is to encourage developers to add arch tests to buildout perf's test coverage, without dumping everything intools/perf/tests.Signed-off-by: Matt Fleming Cc: Adrian Hunter Cc: Andi Kleen Cc: Fenghua Yu Cc: Jiri Olsa Cc: Kanaka Juvva Cc: Peter Zijlstra Cc: Vikas Shivappa Cc: Vince Weaver Link: http://lkml.kernel.org/n/tip-p4uc1c15ssbj8xj7ku5slpa6@git.kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/arch/x86/tests/Build

5e8c0fb6 - perf build: Add arch x86 objects building

Tue, 30 Dec 2014 13:03:40 +0000

perf build: Add arch x86 objects buildingMove the x86 arch objects building under build framework to be includedin the libperf build object.Adding also arch/$(ARCH)/Build files for the rest of the archs. Thereason for this is that in arch/Build we now do: +libperf-y += $(ARCH)/which would make the build to fail on other architectures, because thebuild framework requires 'Build' file in nested directories and thispatch adds it only for x86.Signed-off-by: Jiri Olsa Tested-by: Sukadev Bhattiprolu Tested-by: Will Deacon Cc: Alexis Berlemont Cc: Borislav Petkov Cc: Corey Ashford Cc: David Ahern Cc: Frederic Weisbecker Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-5enob06z07m7ew6nzzdmp3n2@git.kernel.orgSigned-off-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/arch/x86/tests/Build
