Subject: [PATCH v4 00/23] target-arm: Implement ARMv8.5-MemTag, user mode
Date: Thu, 28 Jan 2021 12:41:18 -1000 [thread overview]
Message-ID: <20210128224141.638790-1-richard.henderson@linaro.org> (raw)
The kernel abi was finally merged into 5.10.
Changes for v4:
* Revamp "Add support for TARGET_TAGGED_ADDRESSES". There are now two
sets of functions in include/exec/, one for tagged and one for
untagged addresses. The former takes a CPUState, and does not
assume current_cpu is a thing. So much for the generic bits...
However, use of current_cpu remains, pushed down to lock_user.
Changing everything that touches that, or get/put_user, is daunting.
* Fix tbi0 vs tbi1 for linux-user.
This had a number of cascading effects.
* Adjust when async errors are noticed.
Changes for v3:
* Split out type changes to separate patches.
* Add doc comments; tweak alloc so that the !PAGE_VALID case is clear.
* Do not overlap PAGE_TARGET_2 with PAGE_RESERVED.
* Use syndrome.h, arm_deliver_fault.
