The current scripting only keeps track of the git SHA-1 of the current HEAD. This can cause confusion in cases where testing ran in a git tree where changes had not yet been checked in. This commit therefore also records the output of "git diff HEAD" to provide the information needed to reconstruct the source tree that was tested. Signed-off-by: NPaul E.

The kvm-test-1-run.sh currently counts "sleep 1" commands to detect hangs. This can fail spectacularly on busy systems, where "sleep 1" might take far longer than one second to complete.

The reaction of kvm-recheck.sh is obscure at best, and easy to miss completely. This commit therefore prints "BUG: Build failed" in the summary at the end of a run. This commit also adds the line of dashes in cases where performance info is not available, and also avoids printing nonsense diagnostics in cases where some of the normal test output is not available. In addition, this commit saves off the .config file even when the build fails. Signed-off-by: NPaul E. McKenney <paulmck@linux.vnet.ibm.com>

Currently, the scripts hard-code arch/x86/boot/bzImage, which does not work well for other architectures. This commit therefore provides a identify_boot_image function that selects the correct bzImage location relative to the top of the Linux source tree. This commit also adds a --bootimage argument that allows selecting some other file, for example, "vmlinux". This change requires that the definition of the QEMU variable be computed earlier in order to identify where to look for the boot image when it comes time to copy it to the results directory.

In a normal torture-test run, the script inherits its environment variables, but this does not work when producing a script that is to run later. Therefore, definitions and exports are prepended to a dryrun script but not to a script that is run immediately. This commit reconciles this by placing definitions and exports at the beginning of the script in both cases. Signed-off-by: NPaul E.

The torture tests need to set specific values for their respective Kconfig options (e.g., CONFIG_LOCK_TORTURE_TEST), and must therefore filter any conflicting definitions from the Kconfig fragment file. Unfortunately, the code in kvm-build.sh was looking only for CONFIG_RCU_TORTURE_TEST. This commit therefore handles the general case of CONFIG_[A-Z]*_TORTURE_TEST. Signed-off-by: NPaul E.

arch/x86/tests/regs_load.S is missing the linker note about the stack requirements, therefore making the linker fall back to an executable stack. As this object gets linked against the final perf binary, it'll needlessly end up with an executable stack. Fix this by adding the appropriate linker note. Also add a global linker flag to prevent future regressions, as suggested by Jiri. This way perf won't get an executable stack even if we fail to add the .GNU-stack linker note to future assembler files. Though, doing so might create regressions the other way around, when (statically) linking against libraries needing an executable stack. But, apparently, regressing in that direction is wanted as it is an indicator of poor code quality -- or just missing linker notes.

Modules installed outside of the kernel's build system should go into "%s/lib/modules/%s/extra", but at present, perf will only look at them when they are in "%s/lib/modules/%s/kernel". Lets encourage good citizenship by relaxing this requirement to "%s/lib/modules/%s". This way open source modules that are out-of-tree have no incentive to start populating a directory reserved for in-kernel modules and I can stop hex-editing my system's perf binary when profiling OSS out-of-tree modules. Feedback from Namhyung Kim correctly revealed that the hex-edits that I had been doing meant that perf was also traversing the build and source symlinks in %s/lib/modules/%s. That is undesireable, so we explicitly exclude them from traversal with a minor tweak to the traversal routine.

Commit 12e55569 "tools lib traceevent: Use helper trace-seq in print functions like kernel does" added a extra trace_seq helper to process string arguments like the kernel does it. But the difference between the kernel and the userspace library is that the kernel's trace_seq structure has a static allocated buffer. The userspace one has a dynamically allocated one. It requires a trace_seq_destroy(), otherwise it produces a nasty memory leak.

This patch proposes to replace this error message by "Perf session creation failed" I believe this issue has been brought to lkml: https://lkml.org/lkml/2014/2/24/458 although this patch only tackles a (small) part of the issue. Additionnaly, this patch improves error reporting in tools/perf/util/data.c open_file_write. Currently, if the call to open fails, the user is unaware of it.
