Before using kcore we need to check that modules are in memory at the same addresses that they were when data was recorded. This is done because, while we could remap symbols to different addresses, the object code linkages would still be different which would provide an erroneous view of the object code. Signed-off-by:

Currently, execution of 'perf trace' reports the following cryptic message to the user: $ perf trace Couldn't read the raw_syscalls tracepoints information! Typically this happens because the user does not have permissions to read the debugfs filesystem. Also handle the case when the kernel was not compiled with debugfs support or when it isn't mounted. Now, the tool prints detailed error messages: $ perf trace Error: Unable to find debugfs Hint: Was your kernel was compiled with debugfs support? Hint: Is the debugfs filesystem mounted? Hint: Try 'sudo mount -t debugfs nodev /sys/kernel/debug' $ perf trace Error: No permissions to read /sys/kernel/debug//tracing/events/raw_syscalls Hint: Try 'sudo mount -o remount,mode=755 /sys/kernel/debug/' Signed-off-by:

The perf_evlist__mmap_read used 'union perf_event' as a placeholder for event crossing the mmap boundary. This is ok for sample shorter than ~PATH_MAX. However we could grow up to the maximum sample size which is 16 bits max. I hit this overflow issue when using 'perf top -G dwarf' which produces sample with the size around 8192 bytes. We could configure any valid sample size here using: '-G dwarf,size'. Using array with sample max size instead for the event placeholder. Also adding another safe check for the dynamic size of the user stack. TODO: The 'struct perf_mmap' is quite big now, maybe we could use some lazy allocation for event_copy size. Signed-off-by:

Patch adds more subtle handling of -C and -N parameters in parse_{cpu,node}_setup_list() functions when there isn't enough NUMA nodes or CPUs present. Instead of assertion and terminating benchmark, partial test is skipped with error message and perf will continue to the next one.

For live sessions we can just access /proc to map an fd to its path, on a best effort way, i.e. sometimes the fd will have gone away when we try to do the mapping, as it is done in a lazy way, only when a reference to such fd is made then the path will be looked up in /proc. This is disabled when processing perf.data files, where we will have to have a way to get getname events, be it via an on-the-fly 'perf probe' event or after a vfs_getname tracepoint is added to the kernel. A first step will be to synthesize such event for the use cases where the threads in the monitored workload exist already.
