2006-12-19fix comment in r128Dave Airlie
2005-11-28Assert an MIT copyright on sis_drm.h, since one was lacking and I createdEric Anholt
that particular file. Its contents have changed a good bit since the original sis code, and the original sis code didn't care much about attribution since it routinely disclaims Precision Insight/VA Linux from responsibility. Also, adjust formatting around license headers (have a comment open immediately before the "Copyright" line, not as a runon of any previous comments) for automatic processing into FreeBSD, where /*- is used to signal the beginning of license headers for automatic compilation of license lists.
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
2004-08-24Merged drmfntbl-0-0-2Dave Airlie
2003-10-17- Move IRQ functions from drm_dma.h to new drm_irq.h and disentangle themEric Anholt
from __HAVE_DMA. This will be useful for adding vblank sync support to sis and tdfx. Rename dma_service to irq_handler, which is more accurately what it is. - Fix the #if _HAVE_DMA_IRQ in radeon, r128, mga, i810, i830, gamma to have the right number of underscores. This may have been a problem in the case that the server died without doing its DRM_IOCTL_CONTROL to uninit.
2003-07-29IRQ code cleanup suggested by Linus TorvaldsMichel Daenzer
i830 build fix
2003-07-25Compile fixes for recent 2.5/2.6 Linux kernels. I hope this doesn't breakMichel Daenzer
the i830 driver or the BSDs. :)
2003-04-26Ensure driver has been initialized (dev_private != NULL) before installingLeif Delgass
irq handler in DRM(irq_install). Modify all drivers to ensure irq handler is removed before cleanup and cleanup is called at takedown. Remove unused buffer private struct fields in i810, i830. Check for lock on init/cleanup in all drivers except i810/i830. The current DDX for i810 and i830 doesn't hold the lock on kernel init (FIXME?).
2002-12-04further vertical blank interrupt cleanups: remove unused variable,Michel Daenzer
non-ambiguous variable names, don't express subtraction in unnecessarily complicated ways
2002-12-03vertical blank interrupt cleanups: use spinlock instead of semaphore, sendMichel Daenzer
signal directly from interrupt handler instead of using a taskqueue (based on feedback by Linus Torvalds)
2002-11-30vertical blank ioctl can send signal instead of blockingMichel Daenzer
2002-10-30Kernel support for vblank syncing on Rage 128 and Matrox.Eric Anholt
