If a task specific event wants user space callchain but does not want
branch stack sampling, enable the LBR call stack facility implicitly.
The LBR call stack facility can help perf to get user space callchain
in case of there is no frame pointer.
Note: this feature only affects how to get user
If a task specific event wants user space callchain but does not want
branch stack sampling, enable the LBR call stack facility implicitly.
The LBR call stack facility can help perf to get user space callchain
in case of there is no frame pointer.
