v2:
- Add VMSTATE_UINT16_SUB_ARRAY to vmstate.h
- Keep backward compatibility on the GIC VMState by storing vCPUs
state in the virt VMState subsection.
- Use h_apr to store APR value for vCPUs, instead of increasing apr 2D
array. This adds a little complexity to the implementation (a bunch
of `if (gic_is_vcpu(cpu))'), but avoid ugly VMState description for
the apr array.
v3:
- Remove the LR caching mechanism as it is probably not worse it.
- Remove the forced secure access hack and replace it with a proper
check (commit 8, function gic_cpu_ns_access()).
- Split the Implementation patch for easier review.
- Misc modifications following the review from Peter on v2.
- Add GICv2 virt extensions support to the arm virt machine.
- Fix vCPU running prio not being recomputed after a write to H_APR.
- Fix group0 hw interrupts deactivation request not being forwarded to
distributor when the GIC is not secure.
- Implement GICD_ISACTIVERn and GICD_ICACTIVERn because KVM uses them.
v4:
- Patch 2: check GICD_ISACTIVERn and GICD_ICACTIVERn access (exist
only in GICv2) [Peter]
- Patch 2: moved after patch 1 to ensure compilation success across
patches [Peter]
- Patch 2: implement GICD_ICACTIVERn reads on GICv2 [Peter]
- Patch 7: Integrated Peter rational about LRs helpers, added
comments to explain what's going on [Peter]
- Patch 9: gic_clear_active(): check that the given PhysicalID is a
valid IRQ [Peter]
- Patch 10: refactor to move out the virt cases for more clarity [Peter]
- Patch 12: Add a validity check on the given vIRQ [Peter]
- Patch 14: Fix a comment on memory region creation [Peter]
- Patch 14: Fix per-core alias creation, that should target the
virtual interfaces, and not the vCPU interfaces [Peter]
- Patch 16: gic_update_internal(): Move the CPU interface enable test
in gic_irq_signaling_enabled() [Peter]
- Patch 17: Stylistic [Peter]
- Patch 20: Rebase onto master
- Patch 20: Merge the two GIC maintenance IRQ constants into one
[Peter]
- Patch 20: Fix Memory region size for GICv2 virtual interface and
vCPU iface. [Peter]
