by chenxiang 13 Mar '24

13 Mar '24

From: caijian <caijian11(a)h-partners.com> Backport the code of enabling 'writable' ID registers from mainline to openEuler 6.6. It is the fundation of live migration between different platforms. Jing Zhang (5): KVM: arm64: Allow userspace to get the writable masks for feature ID registers KVM: arm64: Document KVM_ARM_GET_REG_WRITABLE_MASKS KVM: arm64: Use guest ID register values for the sake of emulation KVM: arm64: Allow userspace to change ID_AA64MMFR{0-2}_EL1 KVM: arm64: Allow userspace to change ID_AA64PFR0_EL1 Oliver Upton (6): KVM: arm64: Advertise selected DebugVer in DBGDIDR.Version KVM: arm64: Reject attempts to set invalid debug arch version KVM: arm64: Bump up the default KVM sanitised debug version to v8p8 KVM: arm64: Allow userspace to change ID_AA64ISAR{0-2}_EL1 KVM: arm64: Allow userspace to change ID_AA64ZFR0_EL1 KVM: arm64: Document vCPU feature selection UAPIs Documentation/virt/kvm/api.rst | 52 +++++ Documentation/virt/kvm/arm/index.rst | 1 + Documentation/virt/kvm/arm/vcpu-features.rst | 48 +++++ arch/arm64/include/asm/kvm_host.h | 2 + arch/arm64/include/uapi/asm/kvm.h | 32 +++ arch/arm64/kvm/arm.c | 10 + arch/arm64/kvm/sys_regs.c | 194 ++++++++++++++++--- include/uapi/linux/kvm.h | 2 + 8 files changed, 309 insertions(+), 32 deletions(-) create mode 100644 Documentation/virt/kvm/arm/vcpu-features.rst -- 2.30.0
