[Xen-devel] [PATCH v4 0/3] Add support for GICv2 on GICv3

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hi all,

This patch series adds support for GICv2 on GICv3. This feature is available
only when the GICv3 hardware is compatible with GICv2.

When it's the case, the same interface is provided in order to use a
virtualize GICv2 (i.e GICC and GICV). This will allow us to re-use the
same vGIC driver.

It has been tested on the ARMv8 Foundation Model with GICv2 and GICv3 as
well as changing the vGIC version emulated for the guest (only on GICv3 host).

A branch with all the patches can be found here:
    git://xenbits.xen.org/people/julieng/xen-unstable.git branch 
gicv2-on-gicv3-v4

For all changes see in each patch.

Sincerely yours,

Julien Grall (3):
  xen/arm: Rename XEN_DOMCTL_CONFIG_GIC_DEFAULT to
    XEN_DOMCTL_CONFIG_GIC_NATIVE
  arm: Allow the user to specify the GIC version
  xen/arm: gic-v3: Add support of vGICv2 when available
