* freedreno/ir3: convert scheduler back to recursive algoRob Clark2015-12-042-127/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I've played with a few different approaches to tweak instruction priority according to how much they increase/decrease register pressure, etc. But nothing seems to change the fact that compared to original (pre-multiple-block-support) scheduler, in some edge cases we are generating shaders w/ 5-6x higher register usage. The problem is that the priority queue approach completely looses the dependency between instructions, and ends up scheduling all paths at the same time. Original reason for switching was that recursive approach relied on starting from the shader outputs array. But we can achieve more or less the same thing by starting from the depth-sorted list. shader-db results: total instructions in shared programs: 113350 -> 105183 (-7.21%) total dwords in shared programs: 219328 -> 211168 (-3.72%) total full registers used in shared programs: 7911 -> 7383 (-6.67%) total half registers used in shader programs: 109 -> 109 (0.00%) total const registers used in shared programs: 21294 -> 21294 (0.00%) half full const instr dwords helped 0 322 0 711 215 hurt 0 163 0 38 4 The shaders hurt tend to gain a register or two. While there are also a lot of helped shaders that only loose a register or two, the more complex ones tend to loose significanly more registers used. In some more extreme cases, like glsl-fs-convolution-1.shader_test it is more like 7 vs 34 registers! Signed-off-by: Rob Clark <[email protected]>
* freedreno/ir3: don't reuse a0.x across blocksRob Clark2015-12-041-7/+14
| | | | | | | | It causes confusion in sched if we need to split_addr() since otherwise we wouldn't easily know which block the new addr instr will be scheduled in. So just side-step the whole situation. Signed-off-by: Rob Clark <[email protected]>
* freedreno/ir3: rename ir3_block::bdRob Clark2015-12-043-11/+11
| | | | | | | | We'll need to add similar for ir3_instruction, but following the pattern to use 'id' seems confusing. Let's just go w/ generic 'data' as the name. Signed-off-by: Rob Clark <[email protected]>
* freedreno/ir3: assign varying locations laterRob Clark2015-11-264-29/+37
| | | | | | | | | | | | | Rather than assigning inloc up front, when we don't yet know if it will be unused, assign it last thing before the legalize pass. Also, realize when inputs are unused (since for frag shader's we can't rely on them being removed from ir->inputs[]). This doesn't make sense if we don't also dynamically assign the inloc's, since we could end up telling the hw the wrong # of varyings (since we currently assume that the # of varyings and max-inloc are related..)

* freedreno/a3xx: rework vinterp/vpsreplRob Clark2015-11-261-12/+37
| | | | | | | | | | | | Make the interpolation / point-sprite replacement mode setup deal with varying packing. In a later commit, we switch to packing just the varying components that are actually used by the frag shader, so we won't be able to assume everything is vec4's aligned to vec4. Which would highly confuse the previous vinterp/vpsrepl logic. Signed-off-by: Rob Clark <[email protected]>

* freedreno/a4xx: use a factor of 32767 for snorm8 blendingIlia Mirkin2015-11-231-5/+34
| | | | | | | | | | | | It appears that the hardware wants the integer to be scaled the same way that the hardware representation is. snorm16 uses one of the float factors, so this is only relevant for snorm8.

| | | | | | | | | | Same fix as on a3xx - set the second (tiny) layer size bitfield to the smallest level's size so that the hw knows not to minify beyond that. This fixes texelFetch sampler3D piglits. Signed-off-by: Ilia Mirkin <[email protected]> Cc: [email protected]
* freedreno/a4xx: only align slices in non-layer_first texturesIlia Mirkin2015-11-211-2/+4
| | | | | | | | | | | | When layer is the container, slices are tightly packed inside of each layer. We don't need any additional alignment. On a3xx, each slice contains all the layers, so having alignment makes sense. This fixes a whole slew of array-related piglits, including texelFetch and tex-miplevel-selection varieties.

| | | | | | | | | | | | | | | The main issue is that the current logic looked into cso->u.tex, which is the wrong side of the union to look into for texture buffers. While I was at it, it was easy enough to add the logic to handle offsets (first_element). - reduce texture buffer size limit (determined experimentally) - don't look at first/last levels, instead look at first/last element - include the first element offset - set offset alignment to 16 (determined experimentally) Signed-off-by: Ilia Mirkin <[email protected]> Signed-off-by: Rob Clark <[email protected]>

Triggered by a TF vertex shader which did: gl_Position = vec4(0.0, 0.0, 0.0, 0.0); resulting in a binning pass variant with no inputs.
