[PATCH v3 0/4] target/arm: Add support for FEAT_DIT, Data Independent Timing

Posted by Rebecca Cran 3 years, 3 months ago

Add support for FEAT_DIT. DIT (Data Independent Timing) is a required
feature for ARMv8.4.

Changes from v2 to v3:

o Fixed PSTATE_SS patch:
  - Reverted the singlestep removal.
  - Fixed saving cpsr into spsr.

o Added DIT to the max 32-bit CPU.

Rebecca Cran (4):
  target/arm: Remove PSTATE_SS from cpsr and move it into env->pstate.
  target/arm: Add support for FEAT_DIT, Data Independent Timing
  target/arm: Set ID_AA64PFR0.DIT and ID_PFR0.DIT to 1 for "max" AA64
    CPU
