Subject: [PATCH v2 0/4] arm64: Fix cpuidle/suspend with pseudo-NMI enabled
Date: Tue, 15 Jun 2021 12:12:23 +0100 [thread overview]
Message-ID: <20210615111227.2454465-1-maz@kernel.org> (raw)
This is a follow-up on the series posted at [1], with some added
fixes. The main difference is the covering of system suspend, although
it is untested (the GICv3 boxes I have don't support system
suspend...).
Tested on an Ampere Altra system.
* From v1:
- Moved the wrapping of cpu_suspend() into the body of the function,
now covering system suspend as well
- Added RBs, TBs.
