perf tools: Rename perf_event_ops to perf_tool

2011-11-28T12:39:28Z

To better reflect that it became the base class for all tools, that must be in each tool struct and where common stuff will be put.

perf annotate: Use build-ids to find the right DSO

2010-05-20T15:15:33Z

We were still using the pathname found on the MMAP event, that could not be the one we used when recording, so use the build-id cache for that, only falling back to use the pathname in the MMAP event if no build-ids are available. With this we now also are able to do secure, seamless offline annotation. Example: [root@doppio linux-2.6-tip]# perf report -g none -v 2> /dev/null | head -10 8.12% Xorg /usr/lib64/libpixman-1.so.0.14.0 0x0000000000026d02 B [.] pixman_rasterize_edges 4.68% firefox /usr/lib64/xulrunner-1.9.1/libxul.so 0x00000000005dbdba B [.] 0x000000005dbdba 3.70% swapper /lib/modules/2.6.34-rc6/build/vmlinux 0xffffffff81022cea !

perf build-id: Move the routine to find DSOs with hits to the lib

2010-02-04T08:33:26Z

Because 'perf record' will have to find the build-ids in after we stop recording, so as to reduce even more the impact in the workload while we do the measurement.
