Subject: [PATCH 0/9] Add static DEXCR support
Date: Wed, 22 Mar 2023 16:46:03 +1100 [thread overview]
Message-ID: <20230322054612.1340573-1-bgray@linux.ibm.com> (raw)
This series is a partial iteration of the RFC [1]. It strips out the dynamic
support and just adds the supporting infrastructure and static DEXCR
configuration. It should therefore not be introducing any new userspace ABI.
I could keep iterating and refactoring, but I figure there's enough
here to get useful feedback on the design.
