From 222dc6582e7afad0cd397452a0c4bcea23efeb04 Mon Sep 17 00:00:00 2001 From: Robert Noland Date: Thu, 5 Mar 2009 00:44:56 -0600 Subject: FreeBSD: We only want drm to ever attach to the primary pci device. Intel 855 chips present the same pci id for both heads. This prevents us from attaching to the dummy second head. All other chips that I am aware of either only present a single pci id, or different ids for each head so that we only match on the correct head. --- bsd-core/drmP.h | 1 + bsd-core/drm_drv.c | 4 ++++ 2 files changed, 5 insertions(+) (limited to 'bsd-core') diff --git a/bsd-core/drmP.h b/bsd-core/drmP.h index 79998e84..a8227c29 100644 --- a/bsd-core/drmP.h +++ b/bsd-core/drmP.h @@ -83,6 +83,7 @@ struct drm_file; #include #include #include +#include #include #include diff --git a/bsd-core/drm_drv.c b/bsd-core/drm_drv.c index d4d50e6a..85e86d36 100644 --- a/bsd-core/drm_drv.c +++ b/bsd-core/drm_drv.c @@ -173,6 +173,10 @@ int drm_probe(device_t dev, drm_pci_id_list_t *idlist) device = pci_get_device(dev); #endif + if (pci_get_class(dev) != PCIC_DISPLAY + || pci_get_subclass(dev) != PCIS_DISPLAY_VGA) + return ENXIO; + id_entry = drm_find_description(vendor, device, idlist); if (id_entry != NULL) { device_set_desc(dev, id_entry->name); -- cgit v1.2.3
