Subject[PATCH v12 0/4] set VSESR_EL2 by user space and support NOTIFY_SEI notification
Date
1. Detect whether KVM can set set guest SError syndrome
2. Support to Set VSESR_EL2 and inject SError by user space.
3. Support live migration to keep SError pending state and VSESR_EL2 value.
4. ACPI 6.1 adds support for NOTIFY_SEI as a GHES notification mechanism, so support this
notification in software, KVM or kernel ARCH code call handle_guest_sei() to let ACP driver
to handle this notification.

Change since V11:
Address James's comments, thanks James
1. Align the struct of kvm_vcpu_events to 64 bytes
2. Avoid exposing the stale ESR value in the kvm_arm_vcpu_get_events()
3. Change variables 'injected' name to 'serror_pending' in the kvm_arm_vcpu_set_events()
4. Change to sizeof(events) from sizeof(struct kvm_vcpu_events) in kvm_arch_vcpu_ioctl()
5. Update the patches commit message and document description


Change since V10:
Address James's comments, thanks James
1. Merge the helper function with the user.
2. Move the ISS_MASK into pend_guest_serror() to clear top bits
3. Make kvm_vcpu_events struct align to 4 bytes
4. Add something check in the kvm_arm_vcpu_set_events()
5. Check kvm_arm_vcpu_get/set_events()'s return value.
6. Initialise kvm_vcpu_events to 0 so that padding transferred to user-space doesn't
contain kernel stack.


Dongjiu Geng (4):
arm64: KVM: export the capability to set guest SError syndrome
arm/arm64: KVM: Add KVM_GET/SET_VCPU_EVENTS
ACPI / APEI: Add SEI notification type support for ARMv8
arm64: handle NOTIFY_SEI notification by the APEI driver
