2008-02-04[965] Convert brw_draw_upload to managing dri_bos, not gl_buffer_objects.Eric Anholt
This helps us avoid a bunch of mess with gl_client_arrays that we filled with unused data and confused readers.
2008-01-14[965] Force a new vertex upload buffer at new batch time.Eric Anholt
Otherwise, we could choose to upload into the temporary VBO that we just fired off to the hardware. Good for a 60% OA performance improvement.
2008-01-10[965] Improve performance by allocating CURBE buffers a page at a time.Eric Anholt
Since each one is only 64b, and kernel allocations are a page anyway, this lets us reduce buffer allocation by packing many CURBEs into one buffer, for each batchbuffer submitted. Improves openarena performance by around 10%.
2008-01-09[965] Allow more than one draw_prims per batchbuffer.Eric Anholt
The comment about (vbo)_exec_api.c appeared to be stale, as the VBO code seems to only use non-named VBOs (not actual VBOs) or freshly-allocated VBO data. This brings a 2x speedup to openarena, because we can submit nearly-full batchbuffers instead of many 450-byte ones.
2008-01-09[965] Replace the always_update dirty flag with BRW_NEW_BATCH.Eric Anholt
This allows us to avoid re-emitting some state when validate_state happens multiple times per batchbuffer. Even though we flush batch per primitive currently, that may still happen already if the primitive changed (this should probably be fixed as well).
2008-01-09[intel] Rename lost_hardware vtbl entry to new_batch.Eric Anholt
Both drivers have ended up relying on lost_hardware being called after each batch buffer, so update the name. This removes one of the calls on 965 whic h was outside of the batchbuffer handling code and just duplicating what had already happened through batchbuffer handling.
2007-12-15[965] Use shared intel_regions.c.Eric Anholt
This adds (so far) unused PBO functions, and holding the lock while writing to regions (which may be shared static screen regions).
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.
2007-09-27[965] Remove AUB file support.Eric Anholt
This code existed to dump logs of hardware access to be replayed in simulation. Since we have real hardware now, it's not really needed.

we render. Currenly requires that some state be re-examined after every LOCK_HARDWARE().

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