Subject: [PATCH v2 0/4] Manage vcpu flags from the host
Date: Mon, 13 Jul 2020 22:05:01 +0100 [thread overview]
Message-ID: <20200713210505.2959828-1-ascull@google.com> (raw)
The aim is to keep management of the flags in the host and out of hyp
where possible. I find this makes it easier to understand how the flags
are used as the responsibilities are clearly divided.
The series applies on top of kvmarm/next after VHE and nVHE have been
separated.
From v1 <20200710095754.3641976-1-ascull@google.com>:
- Split FP change into smaller patches
- Addressed Dave's other comments
Andrew Scull (4):
KVM: arm64: Leave KVM_ARM64_DEBUG_DIRTY updates to the host
KVM: arm64: Predicate FPSIMD vcpu flags on feature support
KVM: arm64: Leave vcpu FPSIMD synchronization in host
KVM: arm64: Stop mapping host task thread flags to hyp
