Hi Frediano, FYI, this is only force DOM0 to use the normal GICv2 drivers. I.e the title of this patch is wrong. Do you have any plan to support hi-silicon vGIC in Xen? This would allow guest running with more than 8 cores.

Until vGIC support is not implemented and tested, this will prevent guest kernels to use their Hip04 driver, or crash when they don't have any. Signed-off-by: Frediano Ziglio <frediano.ziglio@huawei.com> --- xen/arch/arm/gic-v2.c | 6 ++++++ 1 file changed, 6 insertions(+)
