Hello,
Early Cortex-A510 parts have broken dbm. Add them to the list of CPUs with
broken dbm.
The SDEN is available here:
https://developer.arm.com/documentation/SDEN2397239/900
There are three series that would add the Cortex-A510 part macros. I've picked
Anshuman's patch that does this, on the assumption that makes Catalin's life
easier. I haven't spotted that patch on the arm64/for-next/fixes branch, so
I've not included the hash in the prerequisite field of the CC-stable.
That patch may need to go on a stable branch, as the the third series will
likely go via the KVM tree.
Let me know if you want this reposted once that value is known.
This series is based on v5.17-rc1 and can be retrieved from:
https://git.gitlab.arm.com/linux-arm/linux-jm.git a510_errata/dbm/v1
Thanks,
James
