This setting is used by the kselftest runner to stop running a test if it takes longer than the assigned value. However, two of the test cases inside rtc set alarms. These alarms are set to the next beginning of the minute, so each of these test cases may take up to, in the worst case, 60 seconds. In order to allow for all test cases in rtc to run, even in the worst case, when using the kselftest runner, the timeout value should be increased to at least 120. Set it to 180, so there's some additional slack. Correct operation can be tested by running the following command right after the start of a minute (low second count), and checking that all test cases run: ./run_kselftest.sh -c rtc Signed-off-by: Nícolas F.

It's not at all obvious why the test re-enters L2 and re-executes VMCALL, but presumably it serves a purpose. The VMX path doesn't skip vmcall(), and the test can't possibly have passed on SVM, so just do what VMX does.

So use the third field of /sys/block/zram/mm_stat to measure memory usage instead.

This case needs a clean zram environment, change this test by using hot_add/hot_remove interface. So even zram device is being used, we still can add zram device and remove them in cleanup. The two interface was introduced since kernel commit 6566d1a32bf7("zram: add dynamic device add/remove functionality") in v4.2-rc1. If kernel supports these two interface, we use hot_add/hot_remove to slove this problem, if not, just check whether zram is being used or built in, then skip it on old kernel.

There, it is completely fine not to have a GCC at all, but some versions of `which' display an error when the command is not found: which: no aarch64-linux-gnu-gcc in ($PATH) Since the error can safely be ignored, throw it to /dev/null.

After some digging, the reason is that the child exits due to SIGBUS, because it overflows the 1024 byte stack we've reserved for it. To fix the issue, increase the stack size to 8192 bytes (this number is somewhat arbitrary, and was arrived at through experimentation -- I kept doubling until the failure no longer occurred). Also, let's make the issue easier to debug. wait_for_pid() returns an ambiguous value: it may return -1 in all of these cases: 1. waitpid() itself returned -1 2. waitpid() returned success, but we found !WIFEXITED(status). 3. The child process exited, but it did so with a -1 exit code. There's no way for the caller to tell the difference. So, at least log which occurred, so the test runner can debug things. While debugging this, I found that we had !WIFEXITED(), because the child exited due to a signal. This seems like a reasonably common case, so also print out whether or not we have WIFSIGNALED(), and the associated WTERMSIG() (if any). This lets us see the SIGBUS I'm fixing clearly when it occurs. Finally, I'm suspicious of allocating the child's stack on our stack. man clone(2) suggests that the correct way to do this is with mmap(), and in particular by setting MAP_STACK. So, switch to doing it that way instead.

If we run perf in a non-root PID namespace with command: # unshare --fork --pid perf record -e cycles -a -- test_program ... in this case, unshare command creates a child PID namespace and launches perf tool in it, but the issue is the proc fs is not mounted for the non-root PID namespace, this leads to the perf tool gathering process info from its parent PID namespace.

This leads to two prominent issues: - Firstly, PID values are mismatched between thread info and samples. The gathered thread info are coming from the proc fs of the root PID namespace, but samples record its PID from the child PID namespace. - The second issue is profiled program 'test_program' returns its forked PID number from the child PID namespace, perf tool wrongly uses this PID number to retrieve the process info via the proc fs of the root PID namespace. To avoid issues, we need to mount proc fs for the child PID namespace with the option '--mount-proc' when use unshare command: # unshare --fork --pid --mount-proc perf record -e cycles -a -- test_program Conversely, when the proc fs of the root PID namespace is used by child namespace, perf tool can detect the multiple PID levels and nsinfo__is_in_root_namespace() returns false, this patch reports error for this case: # unshare --fork --pid perf record -e cycles -a -- test_program Couldn't synthesize bpf events. Perf runs in non-root PID namespace but it tries to gather process info from its parent PID namespace. Please mount the proc file system properly, e.g. add the option '--mount-proc' for unshare command.

For example: [root@f34 rtla]# rtla osnoise top -t failed to enable the tracer osnoise Could not enable osnoiser tracer for tracing Failed to enable the trace instance Segmentation fault (core dumped) This error happens because the exit code of the tools is trying to destroy the trace instance that failed to be created. Make osnoise_destroy_tool() aware of possible NULL osnoise_tool *, and do not attempt to destroy it. This also simplifies the exit code.
