* llvmpipe: Don't advertise S8_UNORM (with feeble attempt at supporting it).José Fonseca2013-01-292-36/+46
| | | | | | | | | | | | | | S8_UNORM was inadvertedly supported together with Z16_UNORM. I tried to update the code to accomodate stencil-only -- it seemed a simple thing to do -- but "fbo-stencil clear GL_STENCIL_INDEX8" still fails, and it's not worth debugging. Therefore although this change tries to update for S8_UNORM, it also disables it completely. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>
* llvmpipe: Fix deferred depth writes for Z16_UNORM.José Fonseca2013-01-291-1/+6
| | | | | | | | | | This special path hadn't been exercised by my earlier testing, and mask values weren't being properly truncated to match the values. This change fixes that. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>

* gallivm,draw,llvmpipe: mass rename of unit->texture_unit/sampler_unitRoland Scheidegger2013-01-281-16/+16
| | | | | | | | | | | Make it obvious what "unit" this is (no change in functionality). draw still uses "unit" in places where it changes the shader by adding texture sampling itself - it seems like this can't work with shaders using dx10-style sample opcodes (can't mix gl-style and dx10-style sample instructions in a shader).

* gallivm: split sampler and texture stateRoland Scheidegger2013-01-289-84/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Split the sampler interface to use separate sampler and texture (sampler_view) state. This is needed to support dx10-style sampling instructions. This is not quite complete since both draw/llvmpipe don't really track textures/samplers independently yet, as well as the gallivm code not quite using the right sampler or texture index respectively (but it should work for the sampling codes used by opengl). We are however losing some optimizations in the process, apply_max_lod will no longer work, and we potentially could end up with more (unnecessary) recompiles (if switching textures with/without mipmaps only so it shouldn't be too bad). v2: don't use different callback structs for sampler/sampler view functions (which just complicates things), fix up sampling code to actually use the right texture or sampler index, and similar for llvmpipe/draw actually distinguish between samplers and sampler views. v3: fix more of PIPE_MAX_SAMPLER / PIPE_MAX_SHADER_SAMPLER_VIEWS mismatches (both in draw and llvmpipe), based on feedback from José get rid of unneeded static sampler derived state.(which also fixes the only 2 piglit regressions due to a forgotten assignment), fix comments based on Brian's feedback. v4: remove some accidental unrelated whitespace changes Reviewed-by: José Fonseca <[email protected]> Reviewed-by: Brian Paul <[email protected]>
* llvmpipe: turn on integer texture supportRoland Scheidegger2013-01-181-6/+16
| | | | | | | | | | Now that things mostly seem to work enable those formats. Some formats cause crashes (notably RGB8 variants) so switch these off (these crashes are not specific to INT/UINT variants but the state tracker doesn't use them for UNORM etc. formats so it went unnoticed so far).

* llvmpipe: more fixes for integer color buffersRoland Scheidegger2013-01-181-3/+39
| | | | | | | | | | | | Cast back the fake floats to ints, and make sure we don't try to do scaling in format conversion (which only makes sense with normalized values). Also need to disable blending and alpha test (as per spec) for such buffers. This makes fbo-blending from the piglit ext_texture_integer tests work for most formats (some crash, and the luminance and intensity variants have the GB or GBA channels respectively wrong).

* llvmpipe: fix using wrong format with MRT in blend codeRoland Scheidegger2013-01-184-11/+26
| | | | | | | | | | | | | We were passing in the rt index however this was always 0 for non-independent blend case. (The format was only actually used to decide if the color mask covered all channels so this went unnoticed and was discovered by accident.) Additionally, there was a second problem because we do fixups in the key based on color buffer format we cannot use non-independent blend anyway as the fixed up values would never get used. So always turn non-independent blending into independent. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: José Fonseca <[email protected]>

* llvmpipe: fix clearing integer color buffersRoland Scheidegger2013-01-105-31/+87
| | | | | | | | | | | | | We get int/uint clear color value in this case, and util_pack_color can't handle these formats at all (even if it could, float input color isn't what we want). Pass through the color union appropriately and handle the packing ourselves (as I couldn't think of a good generic util solution). This gets piglit fbo_integer_precision_clear and fbo_integer_readpixels_sint_uint from the ext_texture_integer test group from segfault to pass (which only leaves fbo-blending from that group not working). v2: fix up comments

* llvmpipe: Drop PIPE_QUERY_TIME_ELAPSED support.José Fonseca2012-12-203-13/+1
| | | | | | | | | | | | | | | | | It was slightly wrong: we were computing the longest duration of the query among all the rasterizer tasks. Regardless, for tile-based implementations such as llvmpipe, time differences will never be very useful, because rendering before/during/after the query is all interleaved. And this is expected, see ARB_timer_query spec, issue 10. In particular, piglit ext_timer_query-time-elapsed still fails, because it makes assumptions that don't hold true in in tiled architectures. Not sure how to fix that though. Reviewed-by: Dave Airlie <[email protected]> Reviewed-by: Marek Olšák <[email protected]> Reviewed-by: Brian Paul <[email protected]>

* draw/llvmpipe: fix transform feedback position + enable other extensionsDave Airlie2012-12-141-1/+1
| | | | | | | | | | | | | | | | This builds on the previous draw/softpipe patch. So llvmpipe does streamout calls after clip/viewport stages, but we have the pre-clip position stored for later use, so when we are doing transform feedback, and its the position vertex grab the vertex from the stored pre clip position. The perfect fix is too probably add a codegen transform feedback stage in between shader and clip stages, but this is good enough for now.

* llvmpipe: support pipe_resource-based constant buffersBrian Paul2012-12-117-34/+48
| | | | | | | | | | | | | | | | Before this we only supported user-based constant buffers. First, we basically plumb pipe_constant_buffer objects through llvmpipe rather than pipe_resource objects. Second, update llvmpipe_set_constant_buffer() and try_update_scene_state() so they understand both resource- and user-based constant buffers. The problem with user constant buffers is the potential for use-after-free, as seen in some WebGL tests. The next patch will flip the switch for resource-based const buffers.
