[PATCH v2 0/6] target/arm: a few timer fixes while checking FEAT_ECV_POFF

Posted by Alex Bennée 1 month, 2 weeks ago

While I was checking what was needed for FEAT_ECV_POFF I discovered a
few potential correctness issues. We had actually already done the
work for the feature so the final patch is just documentation.

v2
  - added target/arm: gate check on scr_el3 behind ARM_FEATURE_EL3 check
  - ensure gt_recalc_timer has updated hcr_el2

The following still need review:

 target/arm: gate check on scr_el3 behind ARM_FEATURE_EL3 check
