Subject: qemu: Implement GIC
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=608c95c76cee49fe98b913d1b7beb1d728b7ca99;p=people%2Fliuw%2Flibxenctrl-split%2Flibvirt.git

qemu: Implement GIC

The only version that's supported in QEMU is version 2, currently.
Fortunately, it is enabled by aarch64 automatically, so there's
nothing for us that needs to be put onto command line.
