* i965: Massively simplify the intel_upload implementation.Eric Anholt2014-03-261-10/+11
| | | | | | | | | | | | | | | | | | | The implementation kept a page-sized area for uploading data, and uploaded chunks from that to a 64kb-sized streamed buffer. This wasted cache footprint (and extra state tracking to do so) when we want to just write our data into the buffer immediately. Instead, build it around an interface like brw_state_batch() that just gets you a pointer to BO memory to upload your stuff immediately. Improves OpenArena on HSW by 1.62209% +/- 0.355299% (n=61) and on BYT by 1.7916% +/- 0.415743% (n=31). v2: Rebase on Mesa master, drop old prototypes. Re-do performance comparison on a kernel that doesn't punish CPU efficiency improvements. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
* i965: Drop the system-memory temporary allocations for flush explicit.Eric Anholt2014-03-141-1/+6
| | | | | | | While in expected usage patterns nobody will ever hit this path, doubling our bandwidth used seems like a waste, and it cost us extra code too. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
* mesa: allow buffers to be mapped multiple timesMarek Olšák2014-02-251-3/+2
| | | | | | | | | | | | | | | | | | | OpenGL allows a buffer to be mapped only once, but we also map buffers internally, e.g. in the software primitive restart fallback, for PBOs, vbo_get_minmax_index, etc. This has always been a problem, but it will be a bigger problem with persistent buffer mappings, which will prevent all Mesa functions from mapping buffers for internal purposes. This adds a driver interface to core Mesa which supports multiple buffer mappings and allows 2 mappings: one for the GL user and one for Mesa. Note that Gallium supports an unlimited number of buffer and texture mappings, so it's not really an issue for Gallium. v2: fix unmapping in xm_dd.c, remove the GL errors there v3: fix the intel driver (by Fredrik) Reviewed-by: Fredrik Höglund <fredrik@kde.org>

* i965: Try to avoid stalls on the GPU when doing glBufferSubData().Eric Anholt2013-10-231-2/+33
| | | | | | | | | | | | On DOTA2, framerate on dota2-de1.dem in windowed mode on my laptop improves by 7.69854% +/- 0.909163% (n=3). In a microbenchmark hitting this code path (wall time of piglit vbo-subdata-many), runtime decreases from 0.8 to 0.05 seconds. v2: Use out of range start/end instead of separate bool for the active flag (suggestion by Jordan), fix double-upload in the stalling path.

* i965: Pass brw_context to functions rather than intel_context.Kenneth Graunke2013-07-091-6/+6
| | | | | | | | | | | | | | This makes brw_context available in every function that used intel_context. This makes it possible to start migrating fields from intel_context to brw_context. Surprisingly, this actually removes some code, as functions that use OUT_BATCH don't need to declare "intel"; they just use "brw."

* [intel] Merge intel_buffer_objects to shared.Eric Anholt2007-12-151-74/+0
| | | | | 965 gains fixed TTM typing of the buffer object buffers and unused PBO functions, and 915 gains buffer size == 0 fixes from 965.
* [965] Use shared intel_regions.c.Eric Anholt2007-12-151-0/+4
| | | | | This adds (so far) unused PBO functions, and holding the lock while writing to regions (which may be shared static screen regions).
* [965] Convert the driver to dri_bufmgr interface and enable TTM.Eric Anholt2007-12-071-2/+2
| | | | | | | | | | | | | 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.
* Add Intel i965G/Q DRI driver.Eric Anholt2006-08-091-0/+70
