2008-01-10[intel] Add more cliprect modes to cover other meanings for batch emits.Eric Anholt
The previous change gave us only two modes, one which looped over the batch per cliprect (3d drawing) and one that didn't (state updeast). However, we really want 4: - Batch doesn't care about cliprects (state updates) - Batch needs DRAWING_RECTANGLE looping per cliprect (3d drawing) - Batch needs to be executed just once (region fills, copies, etc.) - Batch already includes cliprect handling, and must be flushed by unlock time (copybuffers, clears). All callers should now be fixed to use one of these states for any batchbuffer emits. Thanks to Keith Whitwell for pointing out the failure.

2007-12-14[965] Replace the state cache suballocator with direct dri_bufmgr use.Eric Anholt
The user-space suballocator that was used avoided relocation computations by using the general and surface state base registers and allocating those types of buffers out of pools built on top of single buffer objects. It also avoided calls into the buffer manager for these small state allocations, since only one buffer object was being used. However, the buffer allocation cost appears to be low, and with relocation caching, computing relocations for buffers is essentially free. Additionally, implementing the suballocator required a don't-fence-subdata flag to disable waiting on buffer maps so that writing new data didn't block on rendering using old data, and careful handling when mapping to update old data (which we need to do for unavoidable relocations with FBOs). More importantly, when the suballocator filled, it had no replacement algorithm and just threw out all of the contents and forced them to be recomputed, which is a significant cost. This is the first step, which just changes the buffer type, but doesn't yet improve the hash table to not result in full recompute on overflow. Because the buffers are all allocated out of the general buffer allocator, we can no longer use the general/surface state bases to avoid relocations, and they are set to 0 instead.
2007-12-07[965] Convert the driver to dri_bufmgr interface and enable TTM.Eric Anholt
This is currently believed to work but be a significant performance loss. Performance recovery should be soon to follow. The dri_bo_fake_disable_backing_store() call was added to allow backing store disable like bufmgr_fake.c did, which is a significant performance win (though it's missing the no-fence-subdata part). This commit is a squash merge of the 965-ttm branch, which had some history I wanted to avoid pulling due to noisiness and brokenness at many points for git-bisecting.
