[Qemu-devel] [PATCH 0/6] target/arm: Complete ARMv8.3-PAuth linux-user

Posted by Richard Henderson 6 years, 9 months ago

(1) Fix a bug I introduced at the last moment in the last
    patch set -- enable pac keys during reset, not before.
(2) Add the HWCAP bits.
(3) Add the new prctl
(4) Add a smoke test so that (1) doesn't happen again.

  linux-user: Initialize aarch64 pac keys
  linux-user: Implement PR_PAC_RESET_KEYS
  tests/tcg/aarch64: Add pauth smoke tests

Applied patches 1-4 to target-arm.next (5 has a minor nit
and 6 depends on 5).
