Subject: [PATCH v2 0/7] KVM: arm64: More PMU/debug ID register fixes
Date: Mon, 25 Jan 2021 12:26:31 +0000 [thread overview]
Message-ID: <20210125122638.2947058-1-maz@kernel.org> (raw)
This is a respin of a series I posted in the 5.7 time frame, and
completely forgot about it until I noticed again that a few things
where not what I remembered... Given how long it has been, I'm
pretending this is all new work.
Anyway, this covers a few gaps in our ID register handling for PMU and
Debug, plus the upgrade of the PMU support to 8.4 when possible.
I don't plan to take this into 5.11, but this is a likely candidate
for 5.12. Note that this conflicts with fixes that are on their way to
5.11. I'll probably end-up dragging the fixes into 5.12 to solve it.
* From v1 [1]:
- Upgrade AArch32 to PMUv8.4 if possible
- Don't advertise STALL_SLOT when advertising PMU 8.4
- Add an extra patch replacing raw values for the PMU version with
the already existing symbolaic values
