v5 changes:
- patch 2: moved to target-arm/monitor.c (from target-arm/machine.c)
[Peter]
- patch 3: splitted into three patches: [all from Peter's comments]
- patch 3 (new): leverage kvm_arm_create_scratch_host_vcpu(), tiny
enhancement of old one to suite our need
- patch 4: introduce kvm_support_device() in kvm-all.c
- patch 5: do the implementation.
v4 changes:
- all: rename query-gic-capability to query-gic-capabilities [Andrea]
- patch 3: rename helper function to kvm_support_device, make it
inline and lighter. [Drew]
v3 changes:
- patch 2: remove func declaration, add qmp header [Drew]
- patch 3: being able to detect KVM GIC capabilities even without
kvm enabled [Andrea]: this is a little bit hacky, need some more
review on this.
v2 changes:
- result layout change: use array and dict for the capability bits
rather than a single array of strings [Andrea/Markus]
- spelling out what GIC is in doc [Eric]
This patch is to add ARM-specific command "query-gic-capability".
The new command can report which kind of GIC device the host/QEMU
support. The returned result is in the form of array.
Sample command and output:
{"execute": "query-gic-capability"}
{"return": [{"emulated": false, "version": 3, "kernel": false},
{"emulated": true, "version": 2, "kernel": true}]}
Testing:
Smoke tests on both x86 (emulated) and another moonshot ARM server.
