Erdi Chen 25e319c1ef This patch adds three new ioctl's to the VIA Unichrome/Pro DRM driver:
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.
