[PATCH v2 0/3] target/arm: Fix kvm probe of ID_AA64ZFR0

Posted by Richard Henderson 1 year, 9 months ago

Our probing of this SVE register was done within an incorrect
vCPU environment, so that the id register was always RAZ.

Changes for v2:
  * Include the commit text I forgot.
  * Fix svm thinko.
