[PATCH v2 0/4] Add BHRB Facility Support

Posted by Glenn Miles 7 months, 2 weeks ago

This is a series of patches for adding support for the Branch History
Rolling Buffer (BHRB) facility.  This was added to the Power ISA
starting with version 2.07.  Changes were subsequently made in version
3.1 to limit BHRB recording to instructions run in problem state only
and to add a control bit to disable recording (MMCRA[BHRBRD]).

Glenn Miles (4):
  target/ppc: Add new hflags to support BHRB
  target/ppc: Add recording of taken branches to BHRB
  target/ppc: Add clrbhrb and mfbhrbe instructions
  target/ppc: Add migration support for BHRB
