* broadcom/vc5: Add a test for .ifb in ADD ops.Eric Anholt2018-01-121-0/+1
| | | | | I had a .ifb being decoded weird in sampid, so this is to check that .ifb is fine.
* broadcom/vc5: Add the new tesselation opcodes in V3D 4.1.Eric Anholt2018-01-122-1/+5
|
* broadcom/vc5: Use a physical-reg-only register class for LDVPM.Eric Anholt2018-01-122-8/+21
| | | | | This is needed for LDVPM on V3D 4.x, but will also be needed for keeping values out of the accumulators across THRSW.
* broadcom/vc5: Use the new LDVPM/STVPM opcodes on V3D 4.1.Eric Anholt2018-01-129-51/+197
| | | | | | | | | | | Now, instead of a magic write register for VPM stores we have an instruction to do them (which means no packing of other ALU ops into it), with the ability to reorder the VPM stores due to the offset being baked into the instruction. VPM loads also gain the ability to be reordered by packing the row into the A argument. They also no longer write to the r3 accumulator, and instead must be stored to a physical register.
* broadcom/vc5: Drop dead VC5_QPU_* defines from qpu_instr.c.Eric Anholt2018-01-121-80/+0
| | | | | I had all the packing code in this file at one point, but these defines now live in qpu_pack.c.
* broadcom/vc5: Add support for QPU pack/unpack/disasm of small immediates.Eric Anholt2018-01-124-1/+94
|
* broadcom/vc5: Drop signal bit #defines.Eric Anholt2018-01-122-8/+0
| | | | Signals are more complicated than that, and tables ended up being better.
* broadcom/vc5: Add support for V3Dv4 signal bits.Eric Anholt2018-01-1212-45/+322
| | | | | | | The WRTMUC replaces the implicit uniform loads in the first two texture instructions. LDVPM disappears in favor of an ALU op. LDVARY, LDTMU, LDTLB, and LDUNIF*RF now write to arbitrary registers, which required passing the devinfo through to a few more functions.
* broadcom/vc5: Fix pack/unpack of vfmul input unpack flags.Eric Anholt2018-01-122-0/+40
|
* broadcom/vc5: Introduce v3dx_macros.h and v3dx_pack.h headers.Eric Anholt2018-01-123-1/+88
| | | | | This will be used by vc5 for prefixing functions and including the pack header in v3d-version-dependent code, following the model of anv.
* broadcom/cle: Fix error path of missing a "type" in the XML.Eric Anholt2018-01-121-1/+2
| | | | | | We try to emit a #error and continue so that you can debug the missing type at C compile time, but were missing a couple of definitions in that path (sigh, python).
* broadcom/vc5: Add XML for V3D v4.1 (BCM7278)Eric Anholt2018-01-123-1/+1054

* meson: Use dependencies for nirDylan Baker2018-01-111-2/+2
| | | | | | | | | | | | | | | | | This creates two new internal dependencies, idep_nir_headers and idep_nir. The former encapsulates the generation of nir_opcodes.h and nir_builder_opcodes.h and adding src/compiler/nir as an include path. This ensures that any target that needs nir headers will have the includes and that the generated headers will be generated before the target is build. The second, idep_nir, includes the first and additionally links to libnir. This is intended to make it easier to avoid race conditions in the build when using nir, since the number of consumers for libnir and it's headers are quite high.

* meson: Use consistent styleDylan Baker2018-01-111-4/+1
| | | | | | | | | | | | | | | | | | | | Currently the meosn build has a mix of two styles: arg : [foo, ... bar], and arg : [ foo, ..., bar, ] For consistency let's pick one. I've picked the later style, which I think is more readable, and is more common in the mesa code base. v2: - fix commit message Acked-by: Eric Engestrom <[email protected]> Signed-off-by: Dylan Baker <[email protected]>
* 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: Turn the decimate mode field into an enum in the XML.Eric Anholt2018-01-031-1/+8

* broadcom/vc5: Turn the output image format into an enum.Eric Anholt2018-01-031-51/+55

* broadcom/vc5: Turn the CLE XML's memory format into an enum.Eric Anholt2018-01-031-16/+11

* 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: 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: 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.
