Perf tools
- Factorize the multidimensional sorting between perf report and annotate (will be used by perf trace)
- Implement a perf cmp (profile comparison between two perf.data) (DONE, its called 'perf diff')
- Implement a perf view (GUI)
- Enhance perf trace:
- Handle the cpu field
- Handle the timestamp
- Use the in-perf ip -> symbol resolving
- Use the in-perf pid -> cmdline resolving
- Implement multidimensional sorting by field name
- The feature tests performed only when a file that needs those tests, or at least only when some .c or .h file will be rebuilt
- Packages needed for the build should be checked before we start building object files, such as bison (bpetkov)
- Forward port the page fault tracepoints and use it in 'trace':
- Use the highest precision level available by default, e.g.: cycles:pp
- Use Kconfig to allow selecting features and build minimal version of perf, e.g. one with just 'record' for use in embedded platforms.
- David Ahern prototyped this, dig those patches and update them.
- Make the instruction augmentation in the annotate browser platform specific.
- Right now they are x86 specific but are in the common code.
