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.

2004-09-12	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.

2004-08-24	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.
