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.

2007-12-21[965] Fix and enable separate stencil.Eric Anholt
Note that this does not enable GL_EXT_stencil_two_side, because Mesa's computed _TestTwoSide ends up respecting only STENCIL_TEST_TWO_SIDE_EXT (defaults to GL_FALSE), even if the application uses only GL 2.0 / ATI entrypoints.
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.

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.

projtex_mask is only an 8bit field, and wm.input_size_masks includes other attributes' information, therefore right shift is needed.
