[PATCH 0/3] target/arm: Split mtedesc from vector desc

Posted by Richard Henderson 9 months, 3 weeks ago

This aims to solve an assertion failure in simd_desc() that
is triggered by overflowing the 22-bit simd data field, when
SVE vectors are configured to be long and MTE is enabled.

Gustavo, can you please run this through your test case?
I looked back through the irc log and only see the
memory-tagging-extension.rst test case for PR_SET_TAGGED_ADDR_CTRL,
not one that tests MTE+SVE together.
