[Qemu-devel] [PATCH v4 0/3] ARM: add query-gic-capabilities SMP command

From: Peter Xu
Subject: [Qemu-devel] [PATCH v4 0/3] ARM: add query-gic-capabilities SMP command
Date: Tue, 8 Mar 2016 15:36:19 +0800

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}]}


Smoke tests on both x86 (emulated) and another moonshot ARM server.

Peter Xu (3):
  arm: qmp: add GICCapability struct
  arm: qmp: add query-gic-capabilities interface
  arm: implement query-gic-capabilities
