2020-06-05util: Add util functionality for GL4.1 supportNeha Bhende1-0/+108
This patch adds the following tgsi utilities * tgsi_dynamic_indexing: This utility flattens out the dyanamic indexing of constant buffers * tgsi_vpos: This utility writes zeros to position at index 0 in vertex shader. This utility can be used if there is no shader output in vertex shader * util_make_tess_ctrl_passthrough_shader: This adds passthough tessellation control shader. Input of passthrough tess ctrl shader is output of vertex shader and output is input of tessellation eval shader. If program has tessellation eval shader but no tessellation control shader, this utility can be used to create passthrough tessellation control shader.

2020-05-28util: Initialize pipe_shader_state for passthrough and transform shadersNeha Bhende1-5/+5
mesa/st is initializing pipe_shader_state for user define shaders. This patch intialized pipe_shader_state for all passthough and transform shaders. This fixes crashes for several opengl apps. Issue is found in vmware internal testing Fixes: f01c0565bb9 ("draw: free the NIR IR.")

2018-02-07u_blit,u_simple_shaders: add shader to convert from xrbias formatRoland Scheidegger1-0/+47
We need this to handle some oddball dx10 format (DXGI_FORMAT_R10G10B10_XR_BIAS_A2_UNORM). What you can do with this format is very limited, hence we don't want to add it as a gallium format (we could not express the properties of this format as ordinary format properties neither, so like all special formats it would need specific code for handling it in any case). While here, also nuke the array for different shaders for different writemasks, as it was not actually used (always full masks are passed in for generating shaders).

2018-02-07u_simple_shaders: fix mask handling in util_make_fragment_tex_shader_writemaskRoland Scheidegger1-1/+1
The writemask handling was busted, since writing defaults to output meant they got overwritten by the tex sampling anyway. Albeit the affected components were undefined, so maybe with some luck it still would have worked with some drivers - if not could as well kill it... (This would have affected u_blitter but not u_blit since the latter always used xyzw mask.) Reviewed-by: Brian Paul <brianp@vmware.com>

2016-05-11gallium: refactor pipe_shader_state to support multiple IR'sRob Clark1-6/+12
The goal is to allow the pipe driver to request something other than TGSI, but detect whether what is getting is TGSI vs what it requested. The pipe drivers will always have to support TGSI (and convert that into whatever it is that they prefer), but in some cases we should be able to skip the TGSI intermediate step (such as glsl->nir vs glsl->tgsi->nir). I think pipe_compute_state should get similar treatment. Currently, afaict, it has one user and one consumer, which has allowed it to be sloppy wrt. supporting alternative IR's.

2013-12-03gallium/util: implement layered framebuffer clear in u_blitterMarek Olšák1-0/+26
All bound layers (from first_layer to last_layer) should be cleared. This uses a vertex shader which outputs gl_Layer = gl_InstanceID, so each instance goes to a different layer. By rendering a quad and setting the instance count to the number of layers, it will trivially clear all layers. This requires AMD_vertex_shader_layer (or PIPE_CAP_TGSI_VS_LAYER), which only radeonsi supports at the moment. r600 could do this too. Standard DX11 hardware will have to use a geometry shader though, which has higher overhead.

2010-11-28u_blitter: interpolate clear color using a GENERIC varying instead of COLORMarek Olšák1-4/+7
There are also some u_simple_shaders changes. On r300, the TGSI_SEMANTIC_COLOR varying is a fixed-point number clamped to the range [0,1] and limited to 12 bits of precision. Therefore we can't use it for passing through a clear color in order to clear high precision texture formats. This also makes u_blitter use only one vertex shader instead of two.
