2005-02-01	cleanup patch from Adrian Bunk <bunk@stusta.de>	Dave Airlie

2005-01-27	Fixed multiple devices DMA bug. Fixed PCI path FIRE command detection	Thomas Hellstrom

2005-01-07	via updates: moved the verifier state struct to dev_priv. Implemented AGP	Thomas Hellstrom
	alignment check.
2005-01-05	VIA 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.
2004-12-31	VIA DRM: Stability enhancements and cleanups in via_dma.c Added explicit	Thomas Hellstrom
	licence notice in via_dma.c
2004-12-21	via DRM: Tightened the security for some functions of the	Thomas Hellstrom
	DRM_IOCTL_VIA_DMA_INIT IOCTL. Bumped patchlevel and driver date. XFree86 bug: 2119
2004-12-19	via changes: Fixed typecasting bug in via_dma.c, and possible short-circuit	Thomas 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.
2004-12-13	VIA 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.
2004-12-06	Security 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.
2004-12-03	Added 3D functionality to the via command verifier. Modified the via	Thomas Hellstrom
	ring-buffer code somewhat to workaround hardware problems. Bumped via minor version number.
2004-11-27	Reworked PCI MMIO command buffer parser, and imported code from the Mesa	Thomas 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.
2004-11-03	Fixed bug in via_dma.c. The code didn't check that the lock was held by the	Thomas Hellstrom
	caller. Just that it was held.
2004-11-01	Reworked the jump-code in via_dma.c. The command regulator now seems to	Thomas Hellstrom
	pause correctly after a jump. Removed the debug message from within the interrupt handler of via_irq.c
2004-10-30	Some stabilizing work to the DMA ring-buffer code. Temporarily replaced the	Thomas Hellstrom
	rewind jump with a reinitialization. This makes the code stable on CLE266 and KM400.
2004-10-12	Via updates. Fixed unlikely but possible uint32_t overflow in ring-buffer	Thomas Hellstrom
	code. bumped patchlevel.
2004-10-09	Lindent the via stuff so I can include it in kernel	Dave Airlie

2004-10-08	Changed unsigned to uint32_t in some ioctl parameters. Introduced first	Thomas Hellstrom
	rudimentary command verifier for dma buffers. Changed the decoder futex ioctl parameters. Bumped the via major version number.
2004-09-30	Lindent of core build. Drivers checked for no binary diffs. A few files	Jon 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.
2004-09-27	First check in for DRM that splits core from personality modules	Jon Smirl

2004-09-12	Fix DRM to compile cleanly with recent kernel changes in PCI IO and	Jon Smirl
	DRM_COPY_FROM_USER. PCI IO changes in 2.6.9-rc1 bk currently.
2004-09-07	Added IOCTL for writing 2D DMA command buffers over PCI. Bumped minor	Thomas Hellstrom
	version number.
2004-08-30	Fix copy_from_user return value ignored warning at via_dma.c:168.	Erdi Chen

2004-08-27	__NO_VERSION__ hasn't been needed since 2.3 days ditch it...	Dave Airlie

2004-08-26	Rearrange things so that via_dma.c will compile with inline via_check_dma	Jon Smirl

2004-08-24	This patch adds three new ioctl's to the VIA Unichrome/Pro DRM driver:	Erdi Chen
	DRM_IOCTL_VIA_DMA_INIT DRM_IOCTL_VIA_CMDBUFFER DRM_IOCTL_VIA_FLUSH The first ioctl sets up an area in AGP memory that will be used as the ring buffer. The second ioctl copies a command buffer from user space memory to the ring buffer. The third ioctl waits for engine idle until it returns. The motivation for this patch is to avoid the wait for engine idle call before each buffer flush in the current DRI driver. With this patch, the DRI driver can continue to flush its buffer as long as there is free space in the ring buffer. This patch adds an additional copy operation on the command buffer. This buffer copying is necessary to support multiple DRI clients rendering simultaneously. Otherwise, more CPU time will be spent in the busy loop waiting for engine idle between DRI context switch. Even in the single client case, the tradeoff is reasonable in comparision to the kernel call to check for free buffer space for the client to render directly to the ring buffer.
