2005-08-05Rename the driver hooks in the DRM to something a little moreEric Anholt
understandable: preinit -> load postinit -> (removed) presetup -> firstopen postsetup -> (removed) open_helper -> open prerelease -> preclose free_filp_priv -> postclose pretakedown -> lastclose postcleanup -> unload release -> reclaim_buffers_locked version -> (removed) postinit and version were replaced with generic code in the Linux DRM (drivers now set their version numbers and description in the driver structure, like on BSD). postsetup wasn't used at all. Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating. Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)
2005-04-20A fix for a locking bug which is triggered when a client tries to lock withThomas Hellstrom
flag DMA_QUIESCENT (typically the X server), but gets interrupted by a signal. The locking IOCTL should then return an error, but if DMA_QUIESCENT succeeds it returns 0, and the client falsely thinks it has the lock. In addition The client waits for DMA_QUISCENT and possibly DMA_READY without having the lock.
2005-03-28Via updates:Thomas Hellstrom
New PCI command parser. Moved from via_dma.c to via_verifier.c so functions with similar functionality are close to eachother. Moved video related functions to via_video.c, which might be extended in the future, as new video functionality is added. New device-specific generic IRQ IOCTL, similar to the general VBLANK IOCTL, but with support for multiple device IRQ sources and functionality. Support for Unichrome Pro PM800/CN400 video DMA commands in verifier and PCI parser. Support for Unichrome Pro PM800/CN400 HQV IRQs in the new generic IRQ IOCTL. Bumped minor. New version 2.6.0.
2005-01-19Fix a cut & paste problemAlan Hourihane
2005-01-16The patch makes drmAddBufs/drmMapBufs can handle buffers in video memoryDave Airlie
The attached patch adds a new buffer type DRM_FB_BUFFER. It works like AGP memory but uses video memory. From: austinyuan@viatech.com.cn (fd.o bug 1668) Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-01-11Import Thomas' changes upto 2.4.3 to shared. Small tweak to install target.Keith Whitwell
2004-12-16drm_pciids.h should only 'cleaned' when the shared/ directory exists. WhichAlan Hourihane
the Makefile already knows about, but it was cleaning this file anyway.
2004-12-07Fix up linux 2.4 series Makefiles for via_verifier.cThomas Hellstrom
2004-10-31Allow drivers to override reclaim_buffers in an OS-independent way byFelix Kuehling
passing drm_device_t* as first parameter, like in the BSD version.
2004-10-29Switch SPIN_LOCK_UNLOCKED to spin_lock_init()Jon Smirl
2004-10-28fix for 2.4 buildDave Airlie
2004-10-09remove unused dma remnants that were gamma only - these could cause an oopsDave Airlie
on via
2004-10-08Fix refcount bug in stealth modeJon Smirl
2004-10-07Fix drm_exit to allow for DRM(global) being deleted when framebuffer isJon Smirl
loaded.
2004-09-27Flip the 2.4 check so that it looks for 2.6 instead. This will allow buildsJon Smirl
where we can't determine the version through.
2004-09-24Makefile reminder to build in 2.6 when on 2.6Jon 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.
2004-09-23Remove 2.6 code that allow DRM major device number to be shared. We can addJon Smirl
it back later if needed. Checked DRM on both 2.4 and 2.6 to ensure that it builds and runs.
2004-09-23Add new sysfs support filesJon Smirl
2004-09-231) switches from class_sysfs to drm sysfs implementation to allowJon Smirl
customization 2) compiles again on 2.4, but doesn't work
2004-09-22Create permanent maps of framebuffer, aperture and MMIO registers. AddedFelix Kuehling
chipset-type information in driver data field of Savage PCI-IDs. Added missing PCI-ID 0x8d03 (ProSavageDDR on Pentium boards). Don't require AGP.
2004-09-22Remove hotplug reset support from DRM driver. This will be handled by theJon Smirl
VGA driver when it gets written.
2004-09-22Add *.flags to cvsignore.Eric Anholt
2004-09-21Make DRM permanent maps match broken X behavior. X is mapping regions thatJon Smirl
are both smaller and larger than what the hardware supports. If DRM tries to fix these requests X will fail.
2004-09-20Remove size restriction on permanent addmapJon Smirl
2004-09-20Felix's fix for map request smaller than permanent map sizeJon Smirl
2004-09-20remove HAVE_COUNTERSDave Airlie

__set_current_state()
2004-09-17Add the two GPL licensed I2C support files.Jon Smirl
2004-09-17Add linux sysfs i2c support to radeon driver. This patch adds GPL licensedJon Smirl
files to the linux build but not to the BSD directories.
2004-09-16Let's try adding the dyn-minor patch again. This patch will reuse minorJon Smirl
numbers if a card is hotplugged in/out instead of just having them increase.
2004-09-16Fix drm_scatter to properly report it's availabilityJon Smirl
2004-09-15Back dyn-minor patch out for now. fops handling is broken on some cardsJon Smirl
2004-09-15Don't use module_param if it isn't defined in older kernels.Jon Smirl
2004-09-15Dynamic device minor support. Minor device numbers will be reused if theJon Smirl
device is hotplugged in/out of the system
2004-09-12Fix error path in probe() to release resources if there is an error.Jon Smirl
2004-09-12Make the comment match the codeJon Smirl
2004-09-12Fix DRM to compile cleanly with recent kernel changes in PCI IO andJon Smirl
DRM_COPY_FROM_USER. PCI IO changes in 2.6.9-rc1 bk currently.
2004-09-10More general patch to mark resources in use by all DRM drivers. Makes theJon Smirl
code Linux specific.
