Subject: [PATCH v2 0/3] target/arm: Add support for FEAT_DIT, Data Independent Timing
Date: Thu, 21 Jan 2021 21:45:34 -0700	[thread overview]
Message-ID: <20210122044537.1823-1-rebecca@nuviainc.com> (raw)

As suggested in https://www.mail-archive.com/qemu-devel@nongnu.org/msg767057.html
this second patch contains code to move PSTATE_SS from uncached_cpsr to 
env->pstate.

Being fairly new to both aarch64 and qemu development I hope I'm on the
right track, but I suspect my implementation is incomplete.

Rebecca Cran (3):
  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
