drm: Fix support for PCI domains
(For some reason I thought that went in ages ago ...) This fixes support for PCI domains in what should hopefully be a backward compatible way along with a change to libdrm. When the interface version is set to 1.4, we assume userspace understands domains and the world is at peace. We thus pass proper domain numbers instead of 0 to userspace. The newer libdrm will then try 1.4 first, and fallback to 1.1, along with ignoring domains in the later case (well, except on alpha of course) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
