GTPin configuration options for limiting the profiling scope to specific hardware components, like Execution Units and HW threads

With GTPin, you can narrow profiling to a subset of the HW (slice, dual-sub-slice, sub-slice, specific Execution Unit (EU), or specific HW thread ID (TID)). It is done by using the configuration parameter: --hw_profile_scope. The values provided to this parameter are HEX bit masks.

Usage:

--hw_profile_scope [Slice:bitmask][,DualSubSlice:bitmask][,SubSlice:bitmask][,EU:bitmask][,TID:bitmask]

Note:

• Using an asterisk (*) instead of a bitmask will return all available elements.
• The HW scope elements can be provided in any order.
• Only the HW scope elements to be profiled should be provided.
• At least one element must be provided.

Usage example:

--hw_profile_scope Slice:1,DualSubSlice:2,EU:8,TID:3
The example profiles only slice 0, dual sub slice 1, EU 3, HW thread 0+1, and any sub slice.

--hw_profile_scope TID:6
The example profiles all slices, all dual sub slices, all sub slices, all EUs, and all HW thread IDs 1+2.
