From c17c2f892e23a3c70281a4e79bd7c2c226b1a561 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 6 Aug 2010 13:55:10 +1000 Subject: 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 Signed-off-by: Dave Airlie --- drivers/gpu/drm/drm_ioctl.c | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/gpu/drm/drm_ioctl.c') diff --git a/drivers/gpu/drm/drm_ioctl.c b/drivers/gpu/drm/drm_ioctl.c index 7b03b197fc00..47db4df37a69 100644 --- a/drivers/gpu/drm/drm_ioctl.c +++ b/drivers/gpu/drm/drm_ioctl.c @@ -392,6 +392,7 @@ int drm_setversion(struct drm_device *dev, void *data, struct drm_file *file_pri if (sv->drm_di_minor >= 1) { /* * Version 1.1 includes tying of DRM to specific device + * Version 1.4 has proper PCI domain support */ retcode = drm_set_busid(dev, file_priv); if (retcode) -- cgit v1.2.3-55-g7522
