Subject: [PATCH v2 0/5] target/arm: Reduced-IPA space and highmem=off fixes
Date: Sun, 3 Oct 2021 17:46:00 +0100 [thread overview]
Message-ID: <20211003164605.3116450-1-maz@kernel.org> (raw)
Here's another stab at enabling QEMU on systems with pathologically
reduced IPA ranges such as the Apple M1 (original version at [1]).
Eventually, we're able to run a KVM guest with more than just 3GB of
RAM on a system with a 36bit IPA space, and at most 123 vCPUs.
This series does a few things:
- decouple the enabling of the highmem PCIe region from the highmem
attribute
- introduce a new attribute to control the enabling of the highmem
GICv3 redistributors
- correctly cap the PA range with highmem is off
- generalise the highmem behaviour to any PA range
- disable both highmem PCIe and GICv3 RDs when they are outside of the
PA range
This has been tested on an M1-based Mac-mini running Linux v5.15-rc3.
