2022-03-18	KVM: arm64: Generalise VM features into a set of flags	Marc Zyngier	1	-1/+2
	We currently deal with a set of booleans for VM features, while they could be better represented as set of flags contained in an unsigned long, similarily to what we are doing on the CPU side.

2020-11-10	KVM: arm64: Make kvm_skip_instr() and co private to HYP	Marc Zyngier	1	-1/+1
	In an effort to remove the vcpu PC manipulations from EL1 on nVHE systems, move kvm_skip_instr() to be HYP-specific. EL1's intent to increment PC post emulation is now signalled via a flag in the vcpu structure. Signed-off-by: Marc Zyngier <maz@kernel.org>
2020-11-10	KVM: arm64: Move kvm_vcpu_trap_il_is32bit into kvm_skip_instr32()	Marc Zyngier	1	-1/+1
	There is no need to feed the result of kvm_vcpu_trap_il_is32bit() to kvm_skip_instr(), as only AArch32 has a variable length ISA, and this helper can equally be called from kvm_skip_instr32(), reducing the complexity at all the call sites.

2020-08-09	Merge tag 'kvmarm-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into kvm-next-5.6	Paolo Bonzini	1	-6/+0
	KVM/arm64 updates for Linux 5.9: - Split the VHE and nVHE hypervisor code bases, build the EL2 code separately, allowing for the VHE code to now be built with instrumentation - Level-based TLB invalidation support - Restructure of the vcpu register storage to accomodate the NV code - Pointer Authentication available for guests on nVHE hosts - Simplification of the system register table parsing - MMU cleanups and fixes - A number of post-32bit cleanups and other fixes
2020-07-30	KVM: arm64: Move S1PTW S2 fault logic out of io_mem_abort()	Will Deacon	1	-6/+0
	To allow for re-injection of stage-2 faults on stage-1 page-table walks due to either a missing or read-only memslot, move the triage logic out of io_mem_abort() and into kvm_handle_guest_abort(), where these aborts can be handled before anything else.

2020-07-10	KVM: arm64: clean up redundant 'kvm_run' parameters	Tianjia Zhang	1	-5/+6
	In the current kvm version, 'kvm_run' has been included in the 'kvm_vcpu' structure. For historical reasons, many kvm-related function parameters retain the 'kvm_run' and 'kvm_vcpu' parameters at the same time. This patch does a unified cleanup of these remaining redundant parameters.

2020-05-16	KVM: arm64: Move virt/kvm/arm to arch/arm64	Marc Zyngier	1	-0/+200
	Now that the 32bit KVM/arm host is a distant memory, let's move the whole of the KVM/arm64 code into the arm64 tree. As they said in the song: Welcome Home (Sanitarium).
