Hi
Here are some minor improvements to Intel PT related stuff.
First 3 patches are minor fixes:
perf auxtrace: Fix 'instructions' period of zero
perf report: Fix sample type validation for synthesized callchains
perf intel-pt: Fix potential loop forever
Next 4 are minor improvements:
perf intel-pt: Make logging slightly more efficient
perf script: Allow time to be displayed in nanoseconds
perf tools: Warn when AUX data has been lost
perf tools: Add more documentation to export-to-postgresql.py script
Next 7 add support for branch stacks:
perf auxtrace: Add option to synthesize branch stacks on samples
perf report: Adjust sample type validation for synthesized branch stacks
perf report: Also do default setup for synthesized branch stacks
perf report: Skip events with null branch stacks
perf inject: Set branch stack feature flag when synthesizing branch stacks
perf intel-pt: Move branch filter logic
perf intel-pt: Support generating branch stack
Next 6 allow for arbitrary-sized call stacks:
perf report: Make max_stack value allow for synthesized callchains
perf hists: Allow for max_stack greater than PERF_MAX_STACK_DEPTH
perf callchain: Allow for max_stack greater than PERF_MAX_STACK_DEPTH
perf script: Add a setting for maximum stack depth
perf scripting python: Allow for max_stack greater than
PERF_MAX_STACK_DEPTH
perf script: Make scripting_max_stack value allow for synthesized
callchains
Final 5 let Intel PT be used with autofdo:
perf tools: Add perf_evlist__id2evsel_strict()
perf tools: Add perf_evlist__del()
perf inject: Remove more aux-related stuff when processing instruction
traces
perf inject: Add --strip option to strip out non-synthesized events
perf intel-pt: Add mispred-all config option to aid use with autofdo
