Author: rnoland Date: Sat Jan 10 16:42:13 2009 New Revision: 187025 URL: http://svn.freebsd.org/changeset/base/187025 Log: MFC - Sync drm to HEAD Merged /head/sys:r186295,186299-186300,186386,186465 This brings 7 up to date with HEAD. - Use bus_dma to allocate scatter/gather pages for pci GART. This fixes "garbled" screen issues on pci based radeons. - Prevent drm from attaching to secondary devices even if they have the the same pci id. - Attempt at making DRM_DEBUG c99 compliant (needs more work) Approved by: kib Modified: stable/7/sys/ (props changed) stable/7/sys/contrib/pf/ (props changed) stable/7/sys/dev/cxgb/ (props changed) stable/7/sys/dev/drm/drmP.h stable/7/sys/dev/drm/drm_drv.c stable/7/sys/dev/drm/drm_scatter.c stable/7/sys/dev/drm/radeon_irq.c Modified: stable/7/sys/dev/drm/drmP.h ============================================================================== --- stable/7/sys/dev/drm/drmP.h Sat Jan 10 16:24:58 2009 (r187024) +++ stable/7/sys/dev/drm/drmP.h Sat Jan 10 16:42:13 2009 (r187025) @@ -87,6 +87,7 @@ struct drm_file;
