2008-03-16Avoid unnecessary waits for command regulator pause.Thomas Hellstrom
2008-03-16[via] Remove some leftover vars.Thomas Hellstrom
2008-03-16[via] The millionth fixup for the millionth-1 attempt to stabilize the AGPThomas Hellstrom
DMA command submission. It's worth remembering that all new bright ideas on how to make this command reader work properly and according to docs will probably fail :( Bring in some old code.
2008-01-03drm: cleanup DRM_DEBUG() parametersMárton Németh
As DRM_DEBUG macro already prints out the __FUNCTION__ string (see drivers/char/drm/drmP.h), it is not worth doing this again. At some other places the ending "\n" was added. airlied:- I cleaned up a few that this patch missed also
2007-11-22drm: major whitespace/coding style realignment with kernelDave Airlie
2007-11-05drm: remove lots of spurious whitespace.Dave Airlie
Kernel "cleanfile" script run.
2007-07-20Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.Eric Anholt
The data is now in kernel space, copied in/out as appropriate according to the This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal with those failures. This also means that XFree86 4.2.0 support for i810 DRM is lost.
2007-07-20Replace filp in ioctl arguments with drm_file *file_priv.Eric Anholt
As a fallout, replace filp storage with file_priv storage for "unique identifier of a client" all over the DRM. There is a 1:1 mapping, so this should be a noop. This could be a minor performance improvement, as everything on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls went the other direction.
2007-07-20Remove DRM_ERR OS macro.Eric Anholt
This was used to make all ioctl handlers return -errno on linux and errno on *BSD. Instead, just return -errno in shared code, and flip sign on return from shared code to *BSD code.

2005-08-15Port the VIA DRM to FreeBSD. Original patch by Jake, with some cleanup byEric Anholt
me to match other drivers and avoid ifdeffing. The linux via_drv.c will be moved from shared-core to linux-core soon by repocopy. Submitted by: Jake Burkholder <jake@FreeBSD.org> Tested by: unichrome
2005-07-15VIA: Fix sparse warnings (Alexey Dobriyan)Thomas Hellstrom
2005-05-08VIA: Fix for oops when AGP ring-buffer initialization is called and thereThomas Hellstrom
is no AGP memory acquired.
2005-04-18VIA:Thomas Hellstrom
1) Security fix: Stopped possible MMIO access to PCI DMA area for the unichrome Pro. 2) Fixed an odd cpu usage problem by padding small AGP DMA submissions. Bumped patchlevel.
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.
2005-02-01cleanup patch from Adrian Bunk <bunk@stusta.de>Dave Airlie
2005-01-27Fixed multiple devices DMA bug. Fixed PCI path FIRE command detectionThomas Hellstrom
2005-01-07via updates: moved the verifier state struct to dev_priv. Implemented AGPThomas Hellstrom
alignment check.
2005-01-05VIA update:Thomas Hellstrom
Release video futexes when context is destroyed (This was previously done by the X server). Added New Unichrome Pro VIDEO DMA commands to the verifier. Added Quiescent heavyweight lock mode.
2004-12-31VIA DRM: Stability enhancements and cleanups in via_dma.c Added explicitThomas Hellstrom
licence notice in via_dma.c
2004-12-21via DRM: Tightened the security for some functions of theThomas Hellstrom
DRM_IOCTL_VIA_DMA_INIT IOCTL. Bumped patchlevel and driver date. XFree86 bug: 2119
2004-12-19via changes: Fixed typecasting bug in via_dma.c, and possible short-circuitThomas Hellstrom
bug in the cmdbuf_size ioctl. Modified ring-buffer jump code AGAIN, due to new oddities discovered on the Unichrome Pro with faster processors. Bumped patchlevel and driver date.
2004-12-13VIA drm updates:Thomas Hellstrom
1. Improved security check of AGP texture adresses. 2. Hopefully last fix of ring-buffer jump oddities. 3. Added ioctl to check available space and command regulator lag in ring-buffer. This is needed for 3D application responsiveness.
2004-12-06Security and optimization fixes for the via drm:Thomas Hellstrom
1. The command verifier was never initialized in the non-core source tree. 2. Check added that the AGP ring buffer has been initialized before accepting command buffer. 3. Free space check in the AGP buffer is moved to after command verification, which is more optimal in most cases.
2004-12-03Added 3D functionality to the via command verifier. Modified the viaThomas Hellstrom
ring-buffer code somewhat to workaround hardware problems. Bumped via minor version number.
2004-11-27Reworked PCI MMIO command buffer parser, and imported code from the MesaThomas Hellstrom
driver. It can now handle the 3D OpenGL commands from the Mesa unichrome driver. Added vsync frequency detection support. This will be used in the future for XvMC and better frame timing. Bumped minor version number and driver date.
2004-11-03Fixed bug in via_dma.c. The code didn't check that the lock was held by theThomas Hellstrom
caller. Just that it was held.
2004-11-01Reworked the jump-code in via_dma.c. The command regulator now seems toThomas Hellstrom
pause correctly after a jump. Removed the debug message from within the interrupt handler of via_irq.c
2004-10-30Some stabilizing work to the DMA ring-buffer code. Temporarily replaced theThomas Hellstrom
rewind jump with a reinitialization. This makes the code stable on CLE266 and KM400.
2004-10-12Via updates. Fixed unlikely but possible uint32_t overflow in ring-bufferThomas Hellstrom
code. bumped patchlevel.
2004-10-09Lindent the via stuff so I can include it in kernelDave Airlie
2004-10-08Changed unsigned to uint32_t in some ioctl parameters. Introduced firstThomas Hellstrom
rudimentary command verifier for dma buffers. Changed the decoder futex ioctl parameters. Bumped the via major version number.
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
2004-09-12Fix 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.
2004-09-07Added IOCTL for writing 2D DMA command buffers over PCI. Bumped minorThomas Hellstrom
version number.
