I.e. don't drop al->filtered entries, create the hist_entries and use its ->filtered bitmap, that is kept with the same semantics for its bitmap, leaving the filtering to be done at the hist_entry level, i.e. in the UIs. This will allow zooming in/out the filters. Signed-off-by:

Instead of bailing out as soon as we find a filter that applies, go on checking all of them so that we can zoom in/out filters. We also need to make sure we only update al->filtered after thread__find_addr_map(), because there is where al->filtered gets initialized to zero. This will increase the cost of processing when all we don't need this toggling, but will provide flexibility for the TUI and GTK+ interfaces, that will incur in creating the hist_entries just once.

By turning the addr_location->filtered member from a boolean to a u8 bitmap, reusing (and extending) the hist_filter enum for that. This patch doesn't change the logic at all, as it keeps the meaning of al->filtered !0 to mean that the entry _was_ filtered, so no change in how this value is interpreted needs to be done at this point. This will be soon used in upcoming patches. Signed-off-by:

When trying to capture perf data on a system running spejbb2013, perf hung for about 15 minutes. This is because it took that long to gather about 10,000 thread maps and process them. I don't think a user wants to wait that long. Instead, recognize that thread maps are roughly equivalent to pid maps and just quickly copy those instead. To do this, I synthesize 'fork' events, this eventually calls thread__fork() and copies the maps over. The overhead goes from 15 minutes down to about a few seconds. -- V2: based on Jiri's comments, moved malloc up a level and made sure the memory was freed Signed-off-by: -

When some of group member has 0 overhead, it printed previous percentage instead of 0.00%. It's because passing integer 0 as a percent rather than double 0.0 so the remaining bits came from garbage.

Currently if a process creates a bunch of threads using pthread_create and then perf is run in system_wide mode, the mmaps for those threads are not captured with a synthesized mmap event. The reason is those threads are not visible when walking the /proc/ directory looking for /proc/<pid>/maps files. Instead they are discovered using the /proc/<pid>/tasks file (which the synthesized comm event uses). This causes problems when a program is trying to map a data address to a tid. Because the tid has no maps, the event is dropped. Changing the program to look up using the pid instead of the tid, finds the correct maps but creates ugly hacks in the program to carry the correct tid around. Fix this by moving the walking of the /proc/<pid>/tasks up a level (out of the comm function) based on Arnaldo's suggestion. Tweaked things a bit to special case the 'full' bit and 'guest' check.

Introduce futexes to perf-bench and add a program that stresses and measures the kernel's implementation of the hash table. This is a multi-threaded program that simply measures the amount of failed futex wait calls - we only want to deal with the hashing overhead, so a negative return of futex_wait_setup() is enough to do the trick.
