| H A D | lbr.c | diff c301b1d80ed5b806834fe0f739f028f65fb4fb16 Fri Jul 03 07:49:09 CDT 2020 Kan Liang <kan.liang@linux.intel.com> perf/x86/intel/lbr: Add a function pointer for LBR read
The method to read Architectural LBRs is different from previous
model-specific LBR. Perf has to implement a different function.
A function pointer for LBR read is introduced. Perf should initialize
the corresponding function at boot time, and avoid checking lbr_format
at run time.
The current 64-bit LBR read function is set as default.
