The for_each_shell_test macro iterated over all shell tests in the directory using readdir, which does not guarantee any ordering, causing problems on certain fs. However, the order in which they are visited determines the id of the test, in case one wants to run a single test. This patch replaces readdir with scandir using alphabetical sorting. This guarantees that, given the same set of tests, all machines will see the tests in the same order, and, thus, that test ids are consistent. Signed-off-by:

When run as normal user with default sysctl kernel.kptr_restrict=0 and kernel.perf_event_paranoid=2, perf probe fails with: $ ./perf probe move_page_tables Relocated base symbol is not found! The warning message is not much informative. The reason perf fails is because /proc/kallsyms is restricted by perf_event_paranoid=2 for normal user and thus perf fails to read relocated address of the base symbol. Tweaking kptr_restrict and perf_event_paranoid can change the behavior of perf probe. Also, running as root or privileged user works too. Add these details in the warning message. Plus, kmap->ref_reloc_sym might not be always set even if host_machine is initialized. Above is the example of the same. Remove that comment. Reported-by:

The option "opts->full_auxtrace" is checked at the earlier place, if it is false the function will directly bail out. So remove the redundant checking for "opts->full_auxtrace". Suggested-by:

For per-cpu mmap, it should enable timestamp tracing for Arm SPE; this is helpful for samples correlation. To automatically enable the timestamp, a helper arm_spe_set_timestamp() is introduced for setting "ts_enable" format bit. Signed-off-by:

Leo Yan authored
The dummy event is mainly used for mmap, the TIME sample is only needed for per-cpu case so that the perf tool can rely on the correct timing for parsing symbols. And the CPU sample is useless for mmap. The BRANCH_STACK sample bit will be always reset for the dummy event in the function evsel__config(), so don't need to repeatedly reset it for Arm SPE specific. So this patch only enables TIME sample for per-cpu mmap. Signed-off-by:

Now it's hard code to set sample flags for CPU, TIME and TID for SPE event, which is pointless. The CPU is useful for sampling only for per-mmap case, it is used to indicate the AUX trace is associated to which CPU. The TIME sample is not needed for AUX event, since the time for AUX event is not really used and this time is a different thing from the timestamp in Arm SPE trace, the timestamp tracing which is controlled by Arm SPE's config bit. The TID sample is not useful for AUX event. This patch corrects the sample flags for SPE event, it only set CPU sample bit for per-cpu mmap case. Signed-off-by:
