[PATCH V1 4/7] KVM: GICv2: Extract the common code from DT

This patch extracts the common code from the DT probe function. With this patch the DT function only fills out the following info in *vgic. - maint_irq (mapped) - GICH resource - GICV resource Note that vgic->vctrl_base io-remapping is now moved to vgic_v2_probe(). Signed-off-by: Wei Huang

[PATCH V1 6/7] KVM: GICv3: Extract the common code from DT

In preparation for ACPI probing, this patch extracts the DT-neutral code into vgic_v3_probe(). DT function nows fills out the following info in *vgic: - maint_irq (mapped) - GICv resources Signed-off-by: Wei Huang --- virt/kvm/arm/vgic-v3.c | 75

[PATCH V1 7/7] KVM: GICv3: Add ACPI probing function

[PATCH V1 1/7] KVM: GIC: Move GIC DT probing code to GICv2 and GICv3 files

This patch moves GIC DT probing code from vgic.c to GICv2 & GICv3 sub-files. The probing will start from GICv2. If the probing fails, KVM will try to probe GICv3 then. Signed-off-by: Wei Huang --- include/kvm/arm_vgic.h | 6 ++ virt/kvm/arm/vgic-v2.c | 17 ++---

[PATCH V1 2/7] KVM: GIC: Add extra fields to store GICH and GICV resource info

This patch adds new fields in the struct vgic_params to store the resource info (base and size) of GICH & GICV interfaces. These new fields will be used by the DT and ACPI probing code later. Signed-off-by: Wei Huang --- include/kvm/arm_vgic.h | 8 +++-

[PATCH V1 0/7] Enable ACPI support for ARM KVM GIC

This patch set enables ACPI support for KVM GIC. Note that the patches are in fact the V3 of previously submitted patches (search "Enable ACPI support for KVM ARM"). But because Fu Wei includes the arch_timer part in his series [1] and I have substantially re-written the GIC code in this revision,

ARM PCI/MSI KVM passthrough with GICv2M

Hi Alex, I tried to sketch a proposal for guaranteeing the IRQ integrity when doing ARM PCI/MSI passthrough with ARM GICv2M msi-controller. This is based on extended VFIO group viability control, as detailed below. As opposed to ARM GICv3 ITS, this MSI controller does *not* support IRQ

[PATCH] arm64: KVM: Add 48bit PA support for EL2 translations

From: Tirumalesh Chalamarla Systems where RAM is at higher address and MultiNode systems whith higher address RAM, 39 bit max PA for EL2 translations is not sufficient. This patch sets max possible PA(48bit) for EL2 translations. Signed-off-by: Tirumalesh
