[PATCH] target/arm: Two fixes for secure ptw |
Date: |
Wed, 2 Nov 2022 16:47:06 +1100 |
Reversed the sense of non-secure in get_phys_addr_lpae,
and failed to initialize attrs.secure for ARMMMUIdx_Phys_S.
Fixes: 48da29e4 ("target/arm: Add ptw_idx to S1Translate")
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1293
