2009-05-06i965: Split WM constant buffer update from other WM surfaces.Eric Anholt
This can avoid re-uploading constant data when it isn't necessary, and is a step towards not updating other surfaces just because constants change. It also brings the upload of the constant buffer next to the creation. This brings openarena performance up another 4%, to 91% of the Mesa 7.4 branch.
2009-05-06i965: Disentangle VS constant surface state from WM surface state.Eric Anholt
Also, only create VS surface state if there's a VS constant buffer to be uploaded, and set the contents of the buffer at the same time as creation.
2009-04-22i965: checkpoint commit: use two state caches instead of oneBrian Paul
The new, second cache will only be used for surface-related items. Since we can create many surfaces the original, single cache could get filled quickly. When we cleared it, we had to regenerate shaders, etc. With two caches, we can avoid doing that.

2008-10-28i965: Fix check_aperture calls to cover everything needed for the prim at once.Eric Anholt
Previously, since my check_aperture API change, we would check each piece of state against the batchbuffer individually, but not all the state against the batchbuffer at once. In addition to not being terribly useful in assuring success, it probably also increased CPU load by calling check_aperture many times per primitive.
2008-10-28intel: Don't keep intel->pClipRects, and instead just calculate it when needed.Eric Anholt
This avoids issues with dereferencing stale cliprects around intel_draw_buffer time. Additionally, take advantage of cliprects staying constant for FBOs and DRI2, and emit cliprects in the batchbuffer instead of having to flush batch each time they change.
2008-09-28Remove TNL-to-VP tracking from i965Ian Romanick
The i965 driver previously had it's own set of code to convert fixed-function TNL state to a vertex program. Core Mesa has code to do this, so there is no reason to duplicate that effort in the driver. In fact, this duplication leads to bugs when other aspects of the Mesa infrastructure change.

2008-08-08intel-gem: Update to new check_aperture API for classic mode.Eric Anholt
To do this, I had to clean up some of 965 state upload stuff. We may end up over-emitting state in the aperture overflow case, but that should be rare, and I'd rather have the simplification of state management.

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.
2008-01-09[965] Remove drawing rect upload, which is handled (better) by the kernel.Eric Anholt
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.

This driver comes from Tungsten Graphics, with a few further modifications by Intel.
