Subject: [PATCH v2 0/9] KVM: arm64: Initial host support for the Apple M1
Date: Sat, 3 Apr 2021 12:29:22 +0100 [thread overview]
Message-ID: <20210403112931.1043452-1-maz@kernel.org> (raw)
This is a new version of the series initially posted at [1], reworking
the vGIC and timer code to cope with the M1 braindead^Wamusing nature.
Not much has changed, except for the missing irq_ack callback when
taking a timer interrupt, which would leave a screaming interrupt.
Tested with multiple concurrent VMs running from an initramfs.
* From v1 [1]:
- Rebased on Hector's v4 posting[0]
- Dropped a couple of patches that have been merged in the above series
- Fixed irq_ack callback on the timer path
