2016-03-31softpipe: add support for explicit early depth testingDave Airlie1-2/+2
ARB_shader_image_load_store adds support for explicit early depth testing. However we need to make sure we don't overwrite values using the shader written values in this case. This fixes early depth testing in softpipe to conform with those requirements. Reviewed-by: Brian Paul <brianp@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2015-12-11softpipe: implement some support for multiple viewportsEdward O'Callaghan1-2/+3
Mostly related to making sure the rasterizer can correctly pick out the correct scissor box for the current viewport. Signed-off-by: Edward O'Callaghan <eocallaghan@alterapraxis.com> Reviewed-by: Roland Scheidegger <sroland@vmware.com>
2014-06-11softpipe: add layered rendering support.Dave Airlie1-1/+1
This adds support for GL 3.2 layered rendering to softpipe. Reviewed-by: Roland Scheidegger <sroland@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2014-06-11softpipe: add layering to the surface tile cache.Dave Airlie1-1/+1
This adds the layer info to the tile cache. This changes clear_flags to be dynamically allocated as MAX_LAYERS seems like a too big step. Reviewed-by: Roland Scheidegger <sroland@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2014-06-11softpipe: add depth clamping support. (v2)Dave Airlie1-5/+29
This passes the piglit depth clamp tests. this is required for GL 3.2. v2: move min/max up one level, could go further, thanks to Roland for suggestion. v1: Reviewed-by: Brian Paul <brianp@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2013-07-12tgsi: rename the TGSI fragment kill opcodesBrian Paul1-1/+1
TGSI_OPCODE_KIL and KILP had confusing names. The former was conditional kill (if any src component < 0). The later was unconditional kill. At one time KILP was supposed to work with NV-style condition codes/predicates but we never had that in TGSI. This patch renames both opcodes: TGSI_OPCODE_KIL -> KILL_IF (kill if src.xyzw < 0) TGSI_OPCODE_KILP -> KILL (unconditional kill) Note: I didn't just transpose the opcode names to help ensure that I didn't miss updating any code anywhere. I believe I've updated all the relevant code and comments but I'm not 100% sure that some drivers had this right in the first place. For example, the radeon driver might have llvm.AMDGPU.kill and llvm.AMDGPU.kilp mixed up. Driver authors should review their code. Reviewed-by: Jose Fonseca <jfonseca@vmware.com>

2012-01-03softpipe: remove the 32bits limitation on depth(-stencil) formatsMorgan Armand1-1/+43
This patch remove the 32bits limitation. As a side effect, it bring the support for the GL_ARB_depth_buffer_float extension. No regression have been found on piglit, and all tests for GL_ARB_depth_buffer_float pass successfully. Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-03-23softpipe: add special cases for all Z compare modes for 16-bit Z bufferBrian Paul1-173/+48
We had fast paths for PIPE_FUNC_LESS and LEQUAL before. To satisfy OpenGL invariance rules, all depth compare modes should produce the same fragment Z values. Fixes progs/demos/singlebuffer.c

2010-02-18softpipe: fix depth testing problemsBrian Paul1-36/+53
The optimized Z-test functions assumed that the array of incoming quads are adjacent, but that's not always true. The fragment shader can cull intermediate quads, for example. Now these Z-test functions can cope with non-adjacent quads. A little bit of performance is probably lost, but it's probably not worth worring about. This fixes broken glBitmap() Z testing, among other things. (cherry picked from commit d437d905e6924ebc05ec9efe87e1e2c48d75bc13)

2009-07-27softpipe: fastpath for interpolated z16 less depthtestingKeith Whitwell1-4/+139
Because this is interpolated (ie. early) depth, we can build in an assumption about the quads emitted by triangle setup, ie that they are actually linear spans. Interpolate z over those spans in z16 format to save on math & conversion.

2009-07-24softpipe: expand quad pipeline to process >1 quad at a timeKeith Whitwell1-6/+17
This is part one -- we still only pass a single quad down, but the code can now cope with more. The quads must all be from the same tile.
2009-07-22softpipe: remove backwards dependency from tilecache to softpipeKeith Whitwell1-1/+1
The tile cache is a utility, it shouldn't know anything about the entity which is making use of it (ie softpipe). Remove softpipe parameter to all the tilecache function calls, and also remove the need to keep a softpipe pointer in the sampler structs.
