Also it has the jump->arrow lines separated from it by the address/jump target column. - Don't change asm line color when toggling source code view. Requested by Peter Zijlstra.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first column (columns in the near future) are for the per line event overhead(s), that only appear when they are not zero. To clearly separate it, add back a solid vertical line, with just one colour, not influenced by the per line overheads. Then have the addr/offset column, then optionally the dynamic (static in the future) jump->target arrows, if 'j' enables it. Then the instructions.

Further fixes on top of the first iteration: - Sometimes a jump points to an offset with no instructions, make the mark jump targets function handle that, for now just ignoring such jump targets, more investigation is needed to figure out how to cope with that. - Handle jump targets that are outside the function, for now just don't try to draw the connector arrow, right thing seems to be to mark this jump with a -> (right arrow) and handle it like a callq.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As described in the previous patch.

| | * perf session: Skip event correctly for unknown id/machineJiri Olsa2012-04-12

This is not necessary for sample event failing on unknown ID or machine. In such case we know proper size of the event, so we dont need to guess. Also failure statistics are updated correctly so we don't miss any information. Forcing perf_session__process_event to return 0 in case of unknown ID or machine.

| | * perf kvm: Finding struct machine fails for PERF_RECORD_MMAPNikunj A. Dadhania2012-04-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running 'perf kvm --host --guest --guestmount /tmp/guestmount record -a -g -- sleep 2' Was resulting in a segfault. For event type PERF_RECORD_MMAP, event->ip.pid is being used in perf_session__find_machine_for_cpumode, which is not correct. The event->ip.pid field happens to be 0 in this case and results in returning a NULL machine object. Finally, access to self->pid in machine__mmap_name, results in a segfault later. For PERF_RECORD_MMAP type, pass event->mmap.pid. Signed-off-by: Nikunj A.

For example for the 'CPU' PMU we have: aldebaran:~> ll /sys/bus/event_source/devices/cpu/format/* -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/any -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/cmask -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/edge -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/event -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/inv -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/offcore_rsp -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/pc -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/umask those lists of fields contain a specific format: aldebaran:~> cat /sys/bus/event_source/devices/cpu/format/offcore_rsp config1:0-63 So, those who wish to specify raw events can now use the following event format: -e cpu/cmask=1,event=2,umask=3 Most people will not want to specify any events (let alone raw events), they'll just use whatever default event the tools use.
