* vc4: Set the other WADDR in the qpu instruction helpers.Eric Anholt2014-08-241-1/+5
| | | | | Now you don't need to qpu_inst() your instruction with a NOP to get the other waddr set.
* vc4: Merge qpu_a_NOP() and qpu_m_NOP to a single qpu_NOP() helper.Eric Anholt2014-08-243-57/+45
| | | | | | Now that qpu_inst() ignores the WADDR from the other half of the instruction, we can set both the ADD and MUL WADDRs in the NOP helper. Thanks to that, we also no longer need to qpu_inst(NOP, NOP).
* vc4: Ignore WADDRs from the other half of the instruction when merging.Eric Anholt2014-08-241-1/+2
| | | | | | This allows setting the opposite-side WADDR to NOP (a non-zero value) in qpu_* helpers, so that we don't need to qpu_inst() merge them with NOPs all the time just to get the waddr set.
* vc4: Fix LT/GE set-0-or-1 compares.Eric Anholt2014-08-241-1/+1
| | | | | We were using the integer sub, which worked for the common case of EQ and NE. Fixes fs-lessThan-ivec2-ivec2 and other tests.
* vc4: Fix save/restore of the VS/FS in the blitter.Eric Anholt2014-08-231-2/+2
| | | | | | When I made the shader cache take the .fs member and moved the binding point to .bind_fs, I failed to update these. Fixes crashes in copyteximage-related tests.
* vc4: Clear padding of ioctl arguments.Eric Anholt2014-08-231-0/+1
| | | | Fixes valgrind complaints from valgrind being unaware of our ioctls.
* vc4: Add support for fragment discards.Eric Anholt2014-08-224-0/+43
| | | | | | Fixes piglit glsl-fs-discard-01 and -03, and allows a lot of mesa demos to start running. glsl-fs-discard-02 has a problem where the first tile is not getting stored on the first render.
* vc4: Make some helpers for setting condition codes in instructions.Eric Anholt2014-08-223-15/+27
|
* vc4: Avoid using undefined values when there's no color write.Eric Anholt2014-08-221-8/+27
| | | | | | The simulator assertion fails when you read-before-write a temporary value, and there's no point in doing the packing if there was no color written.
* vc4: Emit the scoreboard wait just when it's needed.Eric Anholt2014-08-221-2/+25
| | | | | | | This should improve performance on real hardware by allowing more shader instances to run in parallel. It also fixes assertion failures in tests that don't emit a fragment color, since otherwise we didn't have enough instructions to fit our signals in.
* vc4: Fix FLR for integer values less than 0.Eric Anholt2014-08-221-1/+7
| | | | | | | If we didn't truncate at all, then we don't need to fix for truncation happening in the wrong direction. Fixes piglit builtin-functions/*-floor-*
* vc4: Fix totally broken assertions about inter-instruction reg conflicts.Eric Anholt2014-08-221-3/+18
| | | | | | | | | The spec citation talked about A and B, and I proceeded to pay no attention to whether the waddrs were for A or B. As a result, this pair of instructions would claim to conflict: mov ra4, ra4 ; nop nop, r0, r0 mov.ns ra4, rb4 ; nop nop, r0, r0
* vc4: Add support for all the texture and FBO formats we can.Eric Anholt2014-08-227-72/+203
| | | | | | | Now that tiling is in place, we can expose the other formats. Depth is still broken (need to make changes in the shader), but if you don't expose it things crash all over. SNORM is dropped, but we could re-add it later with some shader fixes to handle converting between [0,1] and [-1,1].
* vc4: Add support for texture tiling.Eric Anholt2014-08-2210-53/+626
| | | | | | This still treats everything as RGBA8888 for the most part, same as before. This is a prerequisite for handling other texture formats, since only RGBA8888 has a raster-layout mode.
* vc4: Fix a typo in the validation for miplevels.Eric Anholt2014-08-221-1/+1
| | | | | | It meant that LUMALPHA was being marked as *many* miplevels, and unsurprisingly wouldn't validate. On the other hand, some miplevel counts wouldn't get the small mips validated at all.
* vc4: Convert to using an enum for texture data typesEric Anholt2014-08-222-20/+43
|
* vc4: Stop complaining about unknown texture channel types.Eric Anholt2014-08-221-10/+0
| | | | | It doesn't matter to this code -- the sampler always returns 8-bit unorm rgba.
* vc4: Include stdio/stdlib in headers so I don't have to include it per file.Eric Anholt2014-08-2215-21/+4
| | | | | There are a few tools I want to have always available, and fprintf() and abort() are among them.
* vc4: Plumb the texture index from TGSI through to the sampler uniforms.Eric Anholt2014-08-191-15/+11
| | | | | This commit and the last one fix ARB_fragment_program/sparse-samplers and 6 other tests.
* vc4: Avoid a null-deref if a sampler index isn't used.Eric Anholt2014-08-191-2/+5
| | | | Part of fixing ARB_fragment_program/sparse-samplers

* vc4: Add support for swizzling of texture colors.Eric Anholt2014-08-183-4/+39
| | | | | Fixes swapped colors on the copypix demo and some piglit tests like pbo-teximage-tiling .
* vc4: Fix handling of non-XYZW swizzles in color outputs.Eric Anholt2014-08-181-6/+6
| | | | | | | The SWIZZLE_1 of the winsys destination was dereffing off the end of the array, which surprisingly often worked out (since nobody reads the rendered value anyway, so whatever junk was referenced in the QIR didn't matter), but shader dumping would sometimes segfault.
* vc4: Extract the swizzle handling from vertex fetch.Eric Anholt2014-08-181-27/+32
| | | | | I want to reuse this elsewhere, and NONE debug output hasn't been useful so I don't miss it being as detailed as it was before.
* vc4: Add support for color masking.Eric Anholt2014-08-181-13/+24
| | | | | This gets fbo-colormask-formats working for core formats, which increases my confidence in some of the swizzle and blend handling.
* vc4: Add a helper for QOP_R4_UNPACK_[ABCD].Eric Anholt2014-08-182-8/+11
|
* vc4: Don't forget to set up the offset for render targets.Eric Anholt2014-08-181-0/+2
| | | | | This almost fixes fbo-generatemipmap rendering, except that the 1x1 level isn't getting rendered.
* vc4: Fix multi-level texture setup.Eric Anholt2014-08-182-2/+12
| | | | | | | We weren't accounting for the level 0 offset in the texture setup (so it only worked if it happened to be a single-level texture), and doing so required that we get the level 0 offset page aligned so that the offset bits don't get interpreted as the texture format and such.
* vc4: Fix viewport handling in the uniforms upload.Eric Anholt2014-08-181-4/+2
| | | | | | | | | | | I had the right viewports in vc4_emit.c, but grabbed the wrong values in the uniform setup, so primitives would claim to be in the wrong parts of the screen. (The vc4_emit.c state looks like it just decides how big the clipping guardband is). This gets fbo-viewport closer to working (which still has the problem that the HW is always guard-band clipping), and fixes inverted FBO rendering in general.

* vc4: Add support for blending.Eric Anholt2014-08-155-12/+199
| | | | | | | | Passes blendminmax and blendsquare. glean's more serious blendFunc fails in simulation due to binner memory overflow (I really need to work around that), and fbo-blending-formats fails due to Mesa refusing one of the getter requests, even before it could fail due to the driver not actually supporting different formats yet.
* vc4: Drop incorrect attempt to incorrectly invert the primconvert hw_mask.Eric Anholt2014-08-151-1/+1
| | | | | | | | The hw_mask is the set of primitives you actually support, so this attempt to provide the set of formats that's unsupported was wrong in two ways (it was intended to be '~' not '!'). However, we only call this code when prim isn't one of the actually supported hw_mask bits, so missing out on the memcpy didn't matter anyway.
* vc4: Use cl_f() instead of cl_u32(fui())Eric Anholt2014-08-151-6/+6

* vc4: Consistently use qir_uniform_f().Eric Anholt2014-08-151-7/+6
|
* vc4: Consume the implicit varyings for points and lines.Eric Anholt2014-08-153-12/+33
| | | | | | | | | | We were triggering simulator assertion failures for not consuming these, and presumably we want to actually make use of them some day (for things like point/line antialiasing) Note that this has the qreg index as 0, which is the same index as the first GL varyings read. This doesn't matter currently, since that number isn't used for anything except dumping.
* vc4: Move the deref of the color buffer for simulator into the simulator.Eric Anholt2014-08-153-8/+4
| | | | | | | At some point I'm going to want to move the information necessary for the host buffer upload/download into the BO so that it's independent of the current vc4->framebuffer, but for now this fixes pointless derefs on non-simulator in vc4_context.c since the dump_fbo() removal

* vc4: Drop the dump_fbo() routine.Eric Anholt2014-08-121-50/+0
| | | | | Now that eglkms is working, and some tests are working under PIGLIT_PLATFORM=gbm, I don't think I need this any more.
* vc4: Claim the GL 2.1 minimum for 3D textures.Eric Anholt2014-08-121-1/+2
| | | | | | | We don't actually do them (or even fake them) currently, but it does get us a bunch of unrelated glean glsl1 tests passing, which previously would error out due to glean assuming the minimums on a 3D texture that 2 of the subtests use.
* vc4: Declare what vertex formats we actually support.Eric Anholt2014-08-121-2/+7
| | | | | We will support more than this eventually, but for now this makes u_vbuf format-convert a few things (32-bit snorm and scaled, doubles) for us.
* vc4: Stash some debug code for format support checks.Eric Anholt2014-08-121-0/+9
| | | | | | This can be useful for looking at context init setup and texture format choices, and there's no reason for the silly retval computation we do if you're not going to have this code (mostly from freedreno) around.
* vc4: Texture format support has nothing to do with VBO format support.Eric Anholt2014-08-121-2/+1
| | | | This was inherited from freedreno, but doesn't apply to us.
* vc4: Fix off-by-one in texture maximum levels.Eric Anholt2014-08-121-1/+1
| | | | It's 2048x2048 that's the max, not 1024x1024.

* vc4: Flip which primitives are considered front-facing.Eric Anholt2014-08-111-1/+1
| | | | This mostly fixes glxgears rendering.
* vc4: Don't forget to set the depth clear value in the packet.Eric Anholt2014-08-111-1/+1
| | | | This gets glxgears partially rendering again.
* vc4: Add support for gl_FragCoord.Eric Anholt2014-08-115-4/+76
| | | | | | | This isn't passing all tests (glsl-fs-fragcoord-zw-ortho, for example), but it does get a bunch more tests passing. v2: Rebase on helpers change.
* vc4: Refactor shader input setup again.Eric Anholt2014-08-111-17/+24
| | | | This makes some space for handling special inputs like fragcoords.
* vc4: Clean up the tile alloc buffer size.Eric Anholt2014-08-111-1/+9
| | | | | | | This prevents some simulator assertion failures, but it does mean (since I've dropped the "* 16" padding) that on real hardware you need a kernel that does overflow memory management (currently, "drm/vc4: Add support for binner overflow memory allocation." in my kernel tree).
