[Qemu-devel] [PATCH v2 0/3] target/arm: SB and PredInv extensions

Posted by Richard Henderson 6 years, 8 months ago

Changes since v2:
  * Rebase on master, cherry-picking one required patch from
    the ARMv8.5-MemTag patch set.
  * Use the same form of TB exit for SB as for ISB.
  * Rename all the bits related to PredInv.
  * Fix registration for PredInv cache flush special regs,
    and spell out why in a comment.
