Try and fix Mobility 128 lockups. Seems to lock when shutting down the X
server from non-standard resolutions, so I've probably messed up the
CCE ioctls somewhat. Default panel resolution seems to be rock solid...
locking fix. Usual caveats apply to using development code.
Includes:
- ctx->Texture.Enabled to ctx->Texture.ReallyEnabled fix
- More useful information in GL_RENDERER string
- More indirect buffer support work
blit buffers can be acquired in batches as needed.
Flush vertex buffers via drmR128FlushVertexBuffer. This ioctl no longer
acquires buffers, it merely flushes and/or discards them.
buffes are handled.
The way buffers are acquired will probably be changed back to what it was
originally, using the DRM_DMA-style ioctl. Texture uploads should grab
as many buffers as needed in a single ioctl.
