New version of the patch with additional functionality.
New version of the patch. This one is using the functionality just recenctly
commited to DRM and since the command verifier now is implemented. This patch
should be fully OK to apply. In addition to the DRM command buffer
functionality, it fixes
1. A locking bug that caused the driver not to keep up with drawable changes.
2. Blitter problems caused by the blitter losing context when the command
buffer is executed through AGP.
3. AGP textures are reenabled.
4. Check for texture memory allocation failure.
The driver avoids filling the ring-buffer by checking the command regulator
lag. Presently this is allowed to be only 50kB. This is tuneable, but larger
values seem to make applications unresponsive while at the same time providing
little performance gain.
With Miniglx, the driver will use the PCI path until someone finds time to
patch the Miniglx server to initialize the AGP ring-buffer.
