modesetting-101 Conflicts: linux-core/drm_sysfs.c
2008-02-20drm: add support for passing state into the suspend hooks.Dave Airlie
fix i915 driver to use state for hibernate save avoidance. Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-02-15switch naming to new proposed schemeDave Airlie
2008-02-13drm: re-write minor number allocation to use an idr.Dave Airlie
Fixup the minor number allocation scheme to use an idr and move the control nodes up higher.
2008-01-09drm: only call suspend/resume on control nodeDave Airlie
2008-01-04drm: add initial support for a drm control device nodeDave Airlie
2008-01-04drm: move drm_head to drm_minor and fix up usersDave Airlie
2007-11-29drm: enable udev node creationDave Airlie
2007-11-09suspend() and resume() need kernel 2.6.22 or laterPatrice Mandin
2007-10-26update DRM sysfs supportJesse Barnes
Make DRM devices use real Linux devices instead of class devices, which are going away. While we're at it, clean up some of the interfaces to take struct drm_device * or struct device * and use the global drm_class where needed instead of passing it around.
2007-09-20drm_sysfs: update sysfs code from kernelDave Airlie
2007-07-16drm: remove drmP.h internal typedefsDave Airlie
2007-07-02Fix must-check warnings and implement a few error paths.Kristian Høgsberg
2006-12-19remove drm pci from 2.5 daysDave Airlie
2006-10-14remove config.h from build no longer exists kbuild does itDave Airlie
2006-02-18major realigment of DRM CVS with kernel code, makes integration much easierDave Airlie
2005-07-03Simplify the sysfs codeJon Smirl
2005-07-03Add sysfs attribute dri_library_name on Linux. code in share-core/via_drv.cJon Smirl
is ok to be shared, it will be passive on BSD.
2005-02-07change DRIVER_ to CORE_ makes things look nicer, also change it so theDave Airlie
driver name is marked on resource allocations
2004-09-30Lindent of core build. Drivers checked for no binary diffs. A few filesJon Smirl
weren't Lindent's because their comments didn't convert very well. A bunch of other minor clean up with no code implact included.
2004-09-27First check in for DRM that splits core from personality modulesJon Smirl
2004-09-24Create new linux-2.6 build. Move all gpl files into the 2.6 build. If youJon Smirl
edit files for 2.6 be sure and break the link to the 2.4 directory and copy the cvs history.
