From: Suravee Suthikulpanit <suravee.suthikulpa...@amd.com>
Currently, the AMD IBS PMU initialize pmu.task_ctx_nr to perf_invalid_context
which only allows IBS to be running only in system-wide mode (e.g. perf record
-a).
IBS hardware is available in each core and should be per-context.
This patch modifies the task_ctx_nr to use the perf_hw_context (default)
instead.
