* 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
* gallium: Add and handle PIPE_CAP_CONDITIONAL_RENDER_INVERTEDTobias Klausmann2014-08-191-0/+1

* 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.
* gallium/vc4: PIPE_CAP_VIDEO_MEMORY return the amount of system ramEmil Velikov2014-08-151-3/+9

* 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: Add support for the FLR opcode.Eric Anholt2014-08-121-0/+18

* 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).
* vc4: Clarify some values implicitly chosen for binning config.Eric Anholt2014-08-111-1/+4
| | | | These #defines are 0, but it should help make math above make more sense.
* vc4: Improve simulator memory allocation.Eric Anholt2014-08-111-4/+20
| | | | This should reduce a bunch of spurious failures in sim.
* vc4: Handle stride==0 in VBO validationEric Anholt2014-08-111-7/+9
|
* vc4: Stash some debug code for looking at what BOs are at what hindex.Eric Anholt2014-08-112-0/+5
| | | | When you're debugging validation, it's nice to know what the BOs are for.
* vc4: Use GEM under simulation even for non-winsys BOs.Eric Anholt2014-08-112-14/+9
| | | | | | | In addition to reducing sim-specific code, it also avoids our local handle allocation conflicting with the host GEM's handle numbering, which was causing vc4_gem_hindex() to not distinguish between winsys BOs and the same-numbered non-winsys bo.
* vc4: Don't forget to unmap the GEM BO when freeing.Eric Anholt2014-08-111-0/+3
| | | | Otherwise it'll stick around forever.
* vc4: Add validation of raster-format textures.Eric Anholt2014-08-112-17/+96
| | | | | | ... and reject everything else, for now. v2: Rebase on v2 of the rendering config validation change.
* vc4: Drop VC4_PACKET_PRIMITIVE_LIST_FORMAT.Eric Anholt2014-08-112-4/+4
| | | | | | It's not relevant to our command streams any more. v2: Fix indentation and a typo in the comment.
* vc4: Add validation that vertex indices don't overflow VBO bounds.Eric Anholt2014-08-112-18/+71

* vc4: Fix the shader record size for extended strides.Eric Anholt2014-08-111-0/+1
| | | | | It turns out they aren't packed when attributes are missing, according to both docs and simulation.
