Subject: [PATCH 0/5] Random debug/PMU fixes for 5.6
Date: Sun, 16 Feb 2020 18:53:19 +0000 [thread overview]
Message-ID: <20200216185324.32596-1-maz@kernel.org> (raw)
Here's a few cleanups and fixes for 5.6, all around our debug and
PMU ID register emulation:
1) Missing RES1 bit in DBGDIDR
2) Limiting PMU version to v8.1
3) Limiting debug version to ARMv8.0
4) Support for ARMv8.4-PMU
(1) was reported by Peter, (2) had a patch from Andrew Murray on the
list, but it's been a while since he was going to rebase and fix it,
so I did bite the bullet. (3) is needed until we implement the right
thing with NV. (4) was too easy not to be done right away.
Patch #2 is a cleanup that helps the following patches.
Unless someone objects, I'd like to take this into 5.6 (except maybe
for the last patch).
