[PATCH 0/3] target/arm: Fix bugs in recent PMU changes

Posted by Peter Maydell 1 year, 7 months ago

This patchset fixes some bugs in the recent changes I made
to the Arm PMU emualtion as part of implementing FEAT_PMUv3p5.

The important patch here is the first one, which fixes a crash
when in icount mode if the guest touched MDCR_EL3, MDCR_EL2,
PMCNTENSET_EL0 or PMCNTENCLR_EL0. The other two are more minor,
things which I noticed while I was looking at the code.

thanks

  target/arm: Mark registers which call pmu_op_start() as ARM_CP_IO
  target/arm: Make writes to MDCR_EL3 use PMU start/finish calls
  target/arm: Update SDCR_VALID_MASK to include SCCD
