* draw: try to prevent overflows on index buffersZack Rusin2013-05-141-2/+2
| | | | | | | | | | | | Pass in the size of the index buffer, when available, and use it to handle out of bounds conditions. The behavior in the case of an overflow needs to be the same as with other overflows in the vertex processing pipeline meaning that a vertex should still be generated but all attributes in it set to zero.

* draw: don't crash on vertex buffer overflowZack Rusin2013-05-141-2/+2
| | | | | | | | | | | | | | We would crash when stride was bigger than the size of the buffer. The correct behavior is to just fetch zero's in this case. Unfortunatly with user_buffer's there's no way to validate the size because currently we're just not getting it. Adjust the draw interface to pass the size along the mapped buffer, which works perfectly for buffer backed vertex_buffers and, in future, it will allow us to plumb user_buffer sizes through the same interface.

* i915: Use Y tiling for texturesStéphane Marchesin2013-05-081-2/+7
| | | | | | | | | | | This basically reverts commit 2acc7193743199701f8f6d1877a59ece0ec4fa5b. With the previous change, we're not batchbuffer limited any longer. So we actually start seeing a performance difference between X and Y tiling. X tiling is funny because it is faster for screen-aligned quads but slower in games. So let's use Y tiling which is 10% faster overall.
* i915g: Optimize batchbuffer sizesStéphane Marchesin2013-05-081-3/+5
| | | | | | | Now that we don't throttle at every batchbuffer, we can shrink the size of batchbuffers to achieve early flushing. This gives a significant speed boost in a lot of games (on the order of 20%).

| | | | | | | | | | | | | | | | It should be unsigned, not enum pipe_flush_flags. Fixed a build error: src/gallium/state_trackers/egl/android/native_android.cpp:426:29: error: invalid conversion from 'int' to 'pipe_flush_flags' [-fpermissive] v2: replace all occurrences of enum pipe_flush_flags by unsigned Signed-off-by: Chia-I Wu <[email protected]> Reviewed-by: Marek Olšák <[email protected]> [olv: document the parameter now that the type is unsigned]
* st/mesa: optionally apply texture swizzle to border color v2Christoph Bumiller2013-04-181-0/+1
| | | | | | | | | | | | This is the only sane solution for nv50 and nvc0 (really, trust me), but since on other hardware the border colour is tightly coupled with texture state they'd have to undo the swizzle, so I've added a cap. The dependency of update_sampler on the texture updates was introduced to avoid doing the apply_depthmode to the swizzle twice. v2: Moved swizzling helper to u_format.c, extended the CAP to provide more accurate information.
* i915g: Release old fragment shader sampler views with current pipeStuart Abercrombie2013-04-171-3/+8

* gallium: add TGSI_SEMANTIC_TEXCOORD,PCOORD v3Christoph Bumiller2013-03-201-0/+2
| | | | | | | | | | | | | | | This makes it possible to identify gl_TexCoord and gl_PointCoord for drivers where sprite coordinate replacement is restricted. The new PIPE_CAP_TGSI_TEXCOORD decides whether these varyings should be hidden behind the GENERIC semantic or not. With this patch only nvc0 and nv30 will request that they be used. v2: introduce a CAP so other drivers don't have to bother with the new semantic v3: adapt to introduction gl_varying_slot enum
* tgsi: use separate structure for indirect address v2Christian König2013-03-191-4/+4
| | | | | | | | | | | | | | To further improve the optimization of source and destination indirect addressing we need the ability to store a reference to the declaration of the addressed operands. Since most of the fields in tgsi_src_register doesn't apply for an indirect addressing operand replace it with a separate tgsi_ind_register structure and so make room for extra information. v2: rename Declaration to ArrayID, put the ArrayID into () instead of [] Signed-off-by: Christian König <[email protected]>

Radeon will use it for buffer eviction heuristics in the kernel (e.g. for queries like how many frames have passed since a buffer was used).

* gallium: add start_slot parameter to set_vertex_buffersMarek Olšák2012-10-312-7/+7
| | | | | | | | | | | | | | | | | | | | | This allows updating only a subrange of buffer bindings. set_vertex_buffers(pipe, start_slot, count, NULL) unbinds buffers in that range. Binding NULL resources unbinds buffers too (both buffer and user_buffer must be NULL). The meta ops are adapted to only save, change, and restore the single slot they use. The cso_context can save and restore only one vertex buffer slot. The clients can query which one it is using cso_get_aux_vertex_buffer_slot. It's currently set to 0. (the Draw module breaks if it's set to non-zero) It should decrease the CPU overhead when using a lot of meta ops, but the drivers must be able to treat each vertex buffer slot as a separate state (only r600g does so at the moment). I can imagine this also being useful for optimizing some OpenGL use cases. Reviewed-by: Brian Paul <[email protected]>

If transfer_map fails, the pointer to the transfer object remains unchanged (i.e. doesn't have to be NULL). Acked-by: Brian Paul <[email protected]>

* gallium: remove PIPE_MAX_VERTEX/GEOMETRY_SAMPLERS #defineBrian Paul2012-08-163-10/+10
| | | | | | | | | | | | PIPE_MAX_SAMPLERS, PIPE_MAX_VERTEX_SAMPLERS and PIPE_MAX_GEOMETRY_SAMPLERS were all defined to the same value (16). In various places we're creating arrays such as sampler_views[PIPE_SHADER_TYPES][PIPE_MAX_SAMPLERS] so we were assuming the same number of max samplers for all shader stages anyway. Of course, drivers are still free to advertise different numbers of max samplers for different shaders.
