This patch set improves upon my LBR v6 patch series posted on LKML several weeks ago. It needs to be applied on top of it. This series improves perf report and perf record when used with taken branch stack sampling. For perf record, and based on users' feedback, it is possible to omit the branch type with the -b option. In that case, the filter is set to the default value of any branch type. The branch-filter option is now used to specify more precise branch types and privilege levels: $ perf record -b foo equivalent to: $ perf record --branch-filter any foo To filter on specific branch types: $ perf record --branch-filter any_call foo For perf report, it is now possible to omit the -b option and yet get branch view mode. Perf report is able to auto-detect if the perf.data file contains samples with branch stack and to switch to the branch mode. It is possible to override this by passing --no-branch-stack. Furthermore, perf report now supports TUI in branch mode. It is possible to naviguate to both the source and destination functions of branches.
