2010-01-19i965: Allow for variable-sized auxdata in the state cache.Eric Anholt
Everything has been constant-sized until now, but constant buffer handling changes will make us want some additional variable sized array.
2009-12-22intel: Replace IS_IGDNG checks with intel->is_ironlake or needs_ff_sync.Eric Anholt
Saves ~480 bytes of code.
2009-11-17Merge branch 'outputswritten64'Ian Romanick
Add a GLbitfield64 type and several macros to operate on 64-bit fields. The OutputsWritten field of gl_program is changed to use that type. This results in a fair amount of fallout in drivers that use programs. No changes are strictly necessary at this point as all bits used are below the 32-bit boundary. Fairly soon several bits will be added for clip distances written by a vertex shader. This will cause several bits used for varyings to be pushed above the 32-bit boundary. This will affect any drivers that support GLSL. At this point, only the i965 driver has been modified to support this eventuality. I did this as a "squash" merge. There were several places through the outputswritten64 branch where things were broken. I foresee this causing difficulties later for bisecting. The history is still available in the branch.

2009-11-11i965: fix EXT_provoking_vertex supportRoland Scheidegger
This didn't work for quad/quadstrips at all, and for all other primitive types it only worked when they were unclipped. Fix up the former in gs stage (could probably do without these changes and instead set QuadsFollowProvokingVertexConvention to false), and the rest in clip stage.
2009-07-20i965: Don't clip everything if FRONT_AND_BACK culling while culling disabled.Eric Anholt
Fixes everything-black with meta_clear_tris on quake4-mpdemo and doom3-demo. Bug #18844, 22077.

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.
2008-04-18i965: initial attempt at fixing the aperture overflowDave Airlie
Makes state emission into a 2 phase, prepare sets things up and accounts the size of all referenced buffer objects. The emit stage then actually does the batchbuffer touching for emitting the objects. There is an assert in dri_emit_reloc if a reloc occurs for a buffer that hasn't been accounted yet.

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.
2007-12-05Revert "[965] Add missing flagging of new stage programs for updating stage ↵Eric Anholt
state." I had forgotten part of brw_state_cache.c that made this fix not relevant for master (last_addr comparison and flagging based on cache id). This reverts commit a4642f3d18bdaebaba31e5dee72fe5de9d890ffb.
2007-12-05[965] Add missing flagging of new stage programs for updating stage state.Eric Anholt
Otherwise, choosing a new program wouldn't necessarily update the state, and and an old program could be executed, leading to various sorts of pretty pictures or hangs.

2007-01-06i965: Avoid branch instructions while in single program flow mode.Eric Anholt
There is an errata for Broadwater that threads don't have the instruction/loop mask stacks initialized on thread spawn. In single program flow mode, those stacks are not writable, so we can't initialize them. However, they do get read during ELSE and ENDIF instructions. So, instead, replace branch instructions in single program flow mode with predicated jumps (ADD to the ip register), avoiding use of the more complicated branch instructions that may fail. This is also a minor optimization as no ENDIF equivalent is necessary. Signed-off-by: Keith Packard <keithp@neko.keithp.com>
