Subject: [PATCH v4 0/7] KVM: arm64: Implement API for vGICv3 live migration
Date: Mon, 28 Sep 2015 18:27:27 +0300	[thread overview]
Message-ID: <cover.1443451687.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.

v3 => v4:
- Split pure refactoring from anything else
- Documentation brought up to date
- Cleaned up 'mmio' structure usage in vgic_attr_regs_access(),
  use call_range_handler() for 64-bit access handling
- Rebased on new linux-next

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
