e19fa7ada1 VIA DRM: verifier: Added verbose palette error reporting, and support for 
stipple palettes together with rudimentary checks for texture palette
    sizes.

ae0db704b4 via changes: Fixed typecasting bug in via_dma.c, and possible short-circuit 
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.

eaaf0a5211 Add the 'Auto' pageflipping command to the verifier. I don't think any 
verification is required for the arguments of this packet from a
    security point of view.

aff0a25485 VIA drm updates: 
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.

c4a87c6883 (Stephane Marchesin, me) add hyperz support to radeon drm. Only fast z 
clear and z buffer compression are working correctly, hierarchical-z is
    not.

1fbfd9eb32 Security and optimization fixes for the via drm: 
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.

4f8fa60286 Reworked PCI MMIO command buffer parser, and imported code from the Mesa 
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.

c9202c8965 Commit WIP of BSD conversion to core model. Compiles for r128, radeon, but 
doesn't run yet. Moves the ioctl definitions for these two drivers back
    to the shared code -- they aren't OS-specific.

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.
