* gallium: add cap for driver specified max combined shader resources.Dave Airlie2017-11-011-0/+1
| | | | | | | | Some hw (evergreen) has a limit on how many combined (images/buffers/mrts) a fragment shader can access. Reviewed-by: Ilia Mirkin <[email protected]> Signed-off-by: Dave Airlie <[email protected]>
* broadcom/vc5: Force blending to treat alpha as 1 for formats without alpha.Eric Anholt2017-10-303-7/+27
| | | | | | | Fixes fbo-blending-formats on RGB8 and 565. We will still need to demote blending to shader code in the MRT case to fix it in general, but that can be added when we start doing 32F blending (which also needs to be done in the shader).
* broadcom/vc5: Do BGRA vs RGBA swapping for the BLEND_CONSTANT_COLOR.Eric Anholt2017-10-304-11/+30
| | | | Fixes many of the fbo-blending-formats tests.
* broadcom/vc5: Pack clear colors according to the TLB internal format/type.Eric Anholt2017-10-302-10/+49
| | | | | | | | | | The previous packing I did got us all the R*16F and R*32F formats, where the pipe format basically matched the TLB's format, but since the clear color will just be memcpyed to the TLB, we should be looking at its format for deciding how to pack. Fixes RGB565, RGB5_A1 and RGBA10 fbo-clear-formats tests and improves 4444.
* broadcom/vc5: Don't do r/b channel swapping on 565.Eric Anholt2017-10-301-1/+7
| | | | The HW's format actually matches the gallium format.
* broadcom/vc5: Use the proper gallium format for our RGB10_A2.Eric Anholt2017-10-301-1/+1
| | | | This keeps us from needing our own reswizzling of the B vs R fields.
* broadcom/vc5: Drop duplicated setup of clip_window_height_in_pixels.Eric Anholt2017-10-301-1/+0
|
* broadcom/vc5: Don't forget to actually turn on stencil testing.Eric Anholt2017-10-301-0/+3
| | | | | I had the rest of stencil state set up, but forgot to actually enable it in the higher level configuration bits packet.
* broadcom/vc5: Set up MSAA texture type according to the internal format.Eric Anholt2017-10-302-2/+39
| | | | | It gets most of EXT_framebuffer_multisample-formats passing, but doesn't really work for texture views.
* broadcom/vc5: Use the sampler view's format, not the resource's.Eric Anholt2017-10-303-8/+1
| | | | | This should help with texture views, though I just noticed this while reading the code.
* broadcom/vc5: Emit raw loads for MSAA buffers.Eric Anholt2017-10-301-0/+58
| | | | | Similar to stores, but we also need to emit dummy stores in between each load, to flush out the previous queued load.
* broadcom/vc5: Use raw stores for MSAA buffers.Eric Anholt2017-10-301-15/+97
| | | | | | | | | | | We were storing the resolved pixels in all cases, but nr_samples > 0 means we should be keeping the per-sample values. We will probably want to change the job structure at some point, as we'll want to recognize full-buffer resolves and do the resolved store in the same job as the original rendering, meaning we'll need to track both the MSAA and single-sample resources in the job. However, this will be enough to build the rest of the MSAA support.
* broadcom/vc5: Add lowering for txf_ms to a txf on a 2x2-scaled texture.Eric Anholt2017-10-301-2/+0
| | | | | | | | | The HW has no native sampler support for multisample textures, but since we only need to support txf_ms and the layout is UIF, we just need to scale up the texcoords and then add in the sample. This drops the old TEXTURE_MSAA_ADDR special uniform, since we're treating MSAA textures as textures, rather than basically texbos like VC4 had to.
* broadcom/vc5: Lay out MSAA textures/renderbuffers as UIF scaled by 4.Eric Anholt2017-10-302-14/+37
| | | | | | We just need to multiply width/height by 2 each, and always set them up as UIF tiling, since that's how the TLB will store them in raw (per-sample) mode.
* broadcom/vc5: Add PIPE_TEX_WRAP_CLAMP support for linear-filtered textures.Eric Anholt2017-10-301-2/+6
| | | | | | I already had the texture's wrapping set up to use different behavior for nearest or linear, so we just needed to saturate the coordinates in linear mode to get the "proper" blend between the edge and border values.
* broadcom/vc5: Disable GL_ARB_transform_feedback3.Eric Anholt2017-10-301-1/+1
| | | | We don't seem to have a way to generally handle gl_SkipComponents.
* broadcom/vc5: Fix gl_FragCoord pixel center setup.Eric Anholt2017-10-301-3/+4
| | | | Fixes glsl-arb-fragment-coord-conventions.
* broadcom/vc5: Always set up 1D textures as raster order.Eric Anholt2017-10-301-0/+5
| | | | | | 1D is the exception to "all V3D textures are tiled", since tiling 1D textures would just waste memory and cache space. This ended up being a problem once we started actually marking 1D textures as 1D instead of 2D.
* broadcom/vc5: Fix GPU hang with no vertex elements used by the VS.Eric Anholt2017-10-301-4/+24
| | | | | | Like VC4, we need to at least have one element set up, but unlike VC4 it seems we don't need to read it to keep the HW happy. Fixes GPU hangs with glsl-no-vertex-attribs.shader_test.
* broadcom/vc5: Fix pasteo that broke vertex texturing.Eric Anholt2017-10-201-1/+1
| | | | | We weren't ever filling in the texture state record, so we'd dereference NULL from the shader.
* broadcom/vc5: Move default attribute value setup to the CSO and fix them.Eric Anholt2017-10-203-29/+23
| | | | | | | | | I was generating some stub values to bring the driver up, but fill them in properly now. We now set 1.0 or 1u as appropriate, and thanks to being in their own BO it fixes piglit failures on the 7268 (where our 4-byte alignment was insufficient). Fixes const-packHalf2x16.shader_test
* broadcom/vc5: Move most of the shader state attribute record to the CSO.Eric Anholt2017-10-204-65/+90
| | | | | This should reduce our draw-time overhead, and puts the code where it should go long term.
* broadcom/vc5: Fix build failure frm nir_shader::stage removal.Eric Anholt2017-10-201-4/+4
| | | | Fixes: 59fb59ad54d3 ("nir: Get rid of nir_shader::stage")
* meson: Add support for the vc5 driver.Eric Anholt2017-10-171-0/+65
| | | | | | | v2: Default vc5 to off, since it requires the simulator currently. Add missing dep on the XML generation from libbroadcom_vc5. Reviewed-by: Dylan Baker <[email protected]> (v1)
* broadcom/vc5: Don't forget to set the RT format for 1555 textures.Eric Anholt2017-10-171-2/+2
| | | | Fixes dEQP-GLES3.functional.fbo.completeness.renderable.texture.color0.rgb5_a1
* broadcom/vc5: Remove the u_resource_vtbl usage.Eric Anholt2017-10-123-25/+18
| | | | Like for vc4, this was just a wasted indirection.
* broadcom/vc5: Fix handling of 5551 textures using the new gallium format.Eric Anholt2017-10-101-2/+2
| | | | | Like vc4, we have the alpha in the low bit. Fixes a bunch of piglit texwrap failures.
* broadcom/vc5: Set the RCL's MSAA mode to match the BCL's MSAA state.Eric Anholt2017-10-101-0/+2
|
* braodcom/vc5: Set up clear color for higher-bpp formats.Eric Anholt2017-10-101-4/+25
| | | | Fixes arb_color_buffer_float-clear
* broadcom/vc5: Set up per-MRT clear colors.Eric Anholt2017-10-103-41/+22
| | | | Fixes fbo-mrt-alphatest.
* broadcom/vc5: Fix blendfactor zero handling.Eric Anholt2017-10-101-0/+1
| | | | | I cut the line out to move it up to the top, when putting "0" in the switch made the compiler complain that that wasn't a valid enum.
* broadcom/vc5: Add support for f32 render targets.Eric Anholt2017-10-101-0/+4
| | | | | The TLB write code is getting ugly and needs a refactoring (that will hopefully handle TLBU uniform coalescing as well).
* broadcom/vc5: Fix color masks for non-independent blending.Eric Anholt2017-10-101-8/+16
| | | | This gets fbo-mrt-alphatest working except for the second RT's clear color.
* broadcom/vc5: Make the BCL's number of render targets setup match the RCL.Eric Anholt2017-10-101-1/+2
|
* braodcom/vc5: Fix tile size setup for MRTs.Eric Anholt2017-10-101-2/+2
| | | | | We need to divide the TLB in two for the 2nd color buffer, and again if the 3rd or 4th are present.
* broadcom/vc5: Start hooking up multiple render targets support.Eric Anholt2017-10-101-3/+9
| | | | We now emit as many TLB color writes as there are color buffers.
* broadcom/vc5: Add support for GL_EXT_provoking_vertex.Eric Anholt2017-10-102-1/+4
| | | | | The bit was missing from the spec, but it's there in the simulator. Fixes the piglit clipflat test.
* braodcom/vc5: Find the actual first TF output for our TF spec.Eric Anholt2017-10-101-1/+6
| | | | This doesn't yet support PSIZ, but gets us at least some of TF working.
* broadcom/vc5: Fix translation of transform feedback's output_register field.Eric Anholt2017-10-101-2/+16
| | | | It's a NIR driver_location, not a slot offset.
* broadcom/vc5: Mark our primitives as needing TF processing.Eric Anholt2017-10-101-4/+11
| | | | | The TF enable state appears to stick around until the next TF enable packet is sent, so we only want to request TF when the shader is using it.
* broadcom/vc5: Fix setup of TF dword output count.Eric Anholt2017-10-101-1/+1
| | | | I missed the "- 1" when reading the spec.
* broadcom/vc5: Fix up a comment from vc4 about the predraw texture setup.Eric Anholt2017-10-101-1/+3
|
* broadcom/vc5: Flush the job when mapping a transform feedback buffer.Eric Anholt2017-10-103-0/+32
| | | | | We will want something fancier for reusing a TF output within the same frame, but we at least need this in order for piglit tests to work.
* broadcom/vc5: Fix handling of interp qualifiers on builtin color inputs.Eric Anholt2017-10-102-3/+3
| | | | | The interpolation qualifier, if specified, is supposed to take precedence over glShadeModel().
* broadcom/vc5: Fix CLIF dumping of lists that aren't capped by a HALT.Eric Anholt2017-10-101-2/+2
| | | | | | | The HW will halt when you hit a HALT packet, or when you hit the end address. Tell CLIF if there's an end address is so that it can stop correctly. (There was usually a 0 byte after the CL, so it would stop anyway).
* broadcom/vc5: Fix depth and stencil clear values.Eric Anholt2017-10-103-14/+10
| | | | | I had misread the packet description: We always have a 32f depth, and a separate u8 stencil.
* broadcom/vc5: Add missing Z16 format.Eric Anholt2017-10-101-0/+1
| | | | We can render to and sample from it just fine.
* braodcom/vc5: Fix incorrect early Z writes in discard shaders.Eric Anholt2017-10-101-1/+6
| | | | Fixes glsl-fs-discard-02.
* broadcom/vc5: Add proper support for base_vertex and base_instance.Eric Anholt2017-10-103-20/+24
| | | | | | I had base_vertex hacked into the shader state setup like in vc4, but it's not correct for big offsets. Using the proper packet is easier and hopefully means we can re-emit shader state setup less frequently.
* broadcom/vc5: Use supertiles and generic tile lists.Eric Anholt2017-10-103-73/+130
| | | | | This massively reduces the size of our RCL setup. It also gets us closer to supporting multicore platforms.
