Subject: [PATCH v3 0/5] KVM: arm64: Implement API for vGICv3 live migration
Date: Fri, 04 Sep 2015 15:40:14 +0300 [thread overview]
Message-ID: <cover.1441370053.git.p.fedin@samsung.com> (raw)
This patchset adds necessary userspace API in order to support vGICv3 live
migration. GICv3 registers are accessed using device attribute ioctls,
similar to GICv2.
V2 => V3:
- KVM_DEV_ARM_VGIC_CPUID_MASK enlarged to 20 bits, allowing more than 256
CPUs.
- Bug fix: Correctly set mmio->private, necessary for redistributor access.
- Added accessors for ICC_AP0R and ICC_AP1R registers
- Rebased on new linux-next
v1 => v2:
- Do not use generic register get/set API for CPU interface, use only
device attributes.
- Introduce size specifier for distributor and redistributor register
accesses, do not assume size any more.
- Lots of refactor and reusable code extraction.
- Added forgotten documentation
