Subject: [PATCH v2 00/17] KVM: arm64: Add NV GICv3 support
Date: Sun, 12 Jan 2025 17:08:28 +0000 [thread overview]
Message-ID: <20250112170845.1181891-1-maz@kernel.org> (raw)
Here's a respin of the NV support for GICv3. The integration branch
containing this (and the rest of the NV stack) is still at [2].
* From v1 [1]:
- Fix the default value for the MI INTID to PPI9, instead of
something fairly random...
- Fail KVM initialisation if asking for NV on HW without a virtual
GICv3.
