* broadcom/vc5: Fix discard_if during control flow.Eric Anholt2018-01-031-1/+1
| | | | | | | I want to do the SETMSF.IFA to discard only if execute == 0 and cond, so our dest of the PUSHZ needs to be nonzero if execute or !cond are nonzero. Fixes dEQP-GLES3.functional.shaders.discard.dynamic_loop_dynamic.
* broadcom/vc5: Don't emit component 3/4 F16 TLB writes for float/vec2.Eric Anholt2018-01-031-1/+2
| | | | | Fixes a simulator assertion failure on dEQP-GLES3.functional.fragment_out.array.fixed.r8_highp_float.
* broadcom/vc5: Introduce enums for internal depth/type, with V3D prefixes.Eric Anholt2018-01-031-27/+28

* broadcom/xml: Fix up safe name confusion with prefixing.Eric Anholt2018-01-031-14/+13
| | | | | | | For enums we were doubling the underscore if the value had a numeric first character of its name (which safe_name() adds an underscore to). A little helper function cleans up the other instance of prefixing while also fixing this.

* broadcom/vc5: Emit flat shade flags for varying components > 24.Eric Anholt2018-01-033-7/+20
| | | | | | | | | | This means that with no flatshading we'll emit the single-byte ZERO_ALL_FLAT_SHADE_FLAGS, and otherwise emit a set of FLAT_SHADE_FLAGS to get all the bits we need set. There's a _SET enum in the packet we could use to possibly set entire ranges of the bitfield without using another packet, but this at least fixes the conformance failure.
* broadcom/vc5: Emit proper flatshading code for glShadeModel(GL_FLAT).Eric Anholt2018-01-033-20/+14
| | | | | | | | In updating the simulator, behavior changed slightly so that our old code wasn't getting glxgears's flatshading interpolated right. Emit flat shading code just like we would for a normal flat-shaded varying, by passing a flag in the shader key for glShadeModel(GL_FLAT) state and customizing the color inputs based on that.
* braodcom/vc5: Rely on OVRTMUOUT always being set.Eric Anholt2018-01-031-0/+2
| | | | | | | | | | | | | | It seems that the HW team has decided that it's the only supported mode, and it's the mode I actually meant to be using but forgot. Our table of return_32_bit should have matched the default non-OVRTMUOUT behavior, so this change should be invisible. However, the change revealed that some my return_size checks for swizzling were a bit confused in the shadow case, so I had to move them to draw time once we have both the sampler and the view together. Fixes assertion failures in the updated simulator, where the non-OVRTMUOUT support has been removed.
* broadcom/vc5: Move texture return channel setup into the compiler.Eric Anholt2018-01-033-18/+41
| | | | | | | | The compiler decides how many LDTMUs we're going to emit, and that must match the P1 flags. This brings the return channel counting to a single place (so all that's passed into the compiler is "how many return channels you may request from this texture's format), and was a necessary step for shadow samplers once we stop using OVRTMUOUT=0.
* broadcom/vc5: Add missing setting of the UIF XOR disable flag in textures.Eric Anholt2017-12-191-0/+1
| | | | | Most piglit textures happened to work out by RGBW not changing in that bit, but it did cause failures in RGBA16F fbo-generatemipmap-formats.
* broadcom/vc5: Fix a typo in memcmp for sig unpack checking.Eric Anholt2017-12-141-1/+1
| | | | | | | This shockingly ended up working out, because only the first byte of *sig is used and (sizeof(*sig) != 0) == 1. Fixes a compiler warning. Link: https://bugs.freedesktop.org/show_bug.cgi?id=104183
* broadcom/vc5: Enable NIR txd lowering on all txd instructions.Eric Anholt2017-12-141-0/+1
| | | | | | | | Fixes almost all of piglit's arb_shader_texture_lod grad tests, except for the base -texgrad/texgradcube ones which fail on what appear to be precision problems. Reviewed-by: Ian Romanick <[email protected]>

* broadcom/vc5: Fix BASE_LEVEL handling with txl.Eric Anholt2017-11-221-2/+4
| | | | | | | The HW doesn't add the base level anywhere (the min/max lod clamping is what does base level), so we need to add it manually in this case. Fixes piglit tex-miplevel-selection *Lod 2D.
* broadcom/vc5: Fix up integer texture handling.Eric Anholt2017-11-191-0/+23
| | | | | | | | The original spec I had didn't expose integer textures and suggested that you use unfiltered floats. Now there are proper formats for them. Fixes 16- and 32-bit texwrap integer tests in piglit, and dEQP-GLES3.functional.fbo.completeness.renderable.renderbuffer.color0.rgb10_a2ui.
* broadcom/vc5: Ensure that there is always a TLB write.Eric Anholt2017-11-171-1/+17
| | | | | This should fix some GPU hangs in our (currently always single-threaded) fragment shaders, and definitely fixes assertion failures in simulation.
* broadcom/vc5: Remove unused v3d_compiler.cAndreas Boll2017-11-081-43/+0

* broadcom/vc5: Do 16-bit unpacking of integer texture returns properly.Eric Anholt2017-11-071-8/+29
| | | | | We were doing f16 unpacks, which trashed "1" values. Fixes many piglit texwrap GL_EXT_texture_integer cases.
* broadcom/vc5: Fix scheduling for a non-SFU R4 write after a dead R4 write.Eric Anholt2017-11-072-5/+33
| | | | | | | The v3d_qpu_writes_r*() were only checking for fixed-function accumulator writes, not normal ALU writes to those regs. Fixes fs-discard-exit-2 on simulation (but not HW).
* broadcom/vc5: Add occlusion query support.Eric Anholt2017-11-071-0/+4
| | | | Fixes all of piglit's OQ tests.
* broadcom/vc5: Fix mipmap filtering enums.Eric Anholt2017-11-071-2/+24
| | | | | | | | The ordering of the values was even less obvious than I thought, with both the mip filter and the min filter being in different bits depending on whether the mip filter is none. Fixes piglit fs-textureLod-miplevels.shader_test
* broadcom/vc5: Fix missing enum decode for indexed primitives.Eric Anholt2017-11-071-2/+1

* broadcom/vc5: Drop padding bits from the bottom of the TSDA address.Eric Anholt2017-11-071-1/+1
| | | | Fixes misaligned-looking addresses in decode.
* broadcom/genxml: Fix decoding of groups with small fields.Kenneth Graunke2017-11-071-2/+4
| | | | | | | | | | | | | | | | | Groups containing fields smaller than a byte probably not being decoded correctly. For example: <group count="32" start="32" size="4"> <field name="Vertex Element Enables" start="0" end="3" type="uint"/> </group> gen_field_iterator_next would properly walk over each element of the array, incrementing group_iter. However, the code to print the actual values only considered iter->field->start/end, which are 0 and 3 in the above example. So it would always fetch bits 3:0 of the current byte, printing the same value over and over. Cc: Eric Anholt <[email protected]>
* broadcom/vc5: Add some comments about the texture/output format ordering.Eric Anholt2017-10-301-7/+15
| | | | | | | | The output formats are consistent with their channels appearing from low to high in their name. Textures are interpreted the same way, but their names may have the channels swapped around. I'm retaining the texture names so that we are consistent with the documentation, but I want to leave a warning for others.
* broadcom/vc5: Stop lowering negates to subs.Eric Anholt2017-10-301-1/+8
| | | | | | | | In the case of fneg(0.0), we were getting back 0.0 instead of -0.0. We were also needing an immediate 0 value for ineg, when there's an opcode to do the job properly. Fixes fs-floatBitsToInt-neg.shader_test.
* broadcom/vc5: Add lowering for txf_ms to a txf on a 2x2-scaled texture.Eric Anholt2017-10-305-2/+96
| | | | | | | | | 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: Keep output height pad out of the store TLB general address.Eric Anholt2017-10-301-1/+1
| | | | The equivalent load already had the pad separated out.

| | | | Improves CLIF dumping output.
* broadcom/xml: Fix address packing for address with >= 8 alignment bits.Eric Anholt2017-10-301-2/+5
| | | | | | | We were handing the intra-byte padding fine, but with a 24-bit address (bottom 8 bits implied 0) we would end up off by 8 bytes in our shift, impacting vc5's load/store general packets (all other packets we have had <8 bits of padding).
* broadcom/clif: Print out the contents of the generic tile list.Eric Anholt2017-10-301-0/+19
| | | | This is the real meat of the RCL, so let's get it printed again.
* broadcom/clif: Move the CL printing part of CL dumps to a helper.Eric Anholt2017-10-301-28/+32
| | | | This will let me reuse the printing for processing branches to other CLs.
* broadcom/vc5: Lower unpack_*_4x8 to normal math.Eric Anholt2017-10-301-0/+3
| | | | | | We only have 2x16 unpacking in our ALUs. To enable this, we also need lower_fdiv for its new instructions, which had been handled at a higher level previously.
* broadcom/vc5: Add PIPE_TEX_WRAP_CLAMP support for linear-filtered textures.Eric Anholt2017-10-302-2/+10
| | | | | | 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/xml: Throw an #error in XML-based codegen for a >1bit boolEric Anholt2017-10-301-0/+3
| | | | | I've debugged two nasty errors now due to copy-and-pasting a bool type when writing a uint field. Make sure I don't do that again.
* broadcom/vc4: Fix bool marking on Rasterizer Oversample Mode.Eric Anholt2017-10-301-1/+1

* broadcom/vc5: Use SETMSF to handle discards.Eric Anholt2017-10-202-25/+12
| | | | | | | | A bit of spec text suggested that (like vc4) condition codes should be used for discards, and the simulator was fine with it, but the 7268 disagrees and you have to use SETMSF instead or the color comes through.
