* vc4: Fix compiler warnings in fail_instr path of QIR validate passRhys Kidd2016-05-311-10/+10
| | | | | | | Introduced in 8e2d0843c02daf5280184f179ae8ed440ac90d7f. Signed-off-by: Rhys Kidd <[email protected]> Reviewed-by: Eric Anholt <[email protected]>
* vc4: Fix doxygen warnings12.0-branchpointRhys Kidd2016-05-302-6/+6
| | | | | | | | Now that vc4 automated code documentation can be generated with doxygen, fix the warnings issued by Doxygen 1.8.11. Signed-off-by: Rhys Kidd <[email protected]> Reviewed-by: Emil Velikov <[email protected]>
* gallium: push offset down to driverStanimir Varbanov2016-05-301-0/+7
| | | | | | | | | | | | | Push offset down to drivers when importing dmabuf. This is needed to more fully support EGL_EXT_image_dma_buf_import when a non-zero offset is specified. Tesing has been done for freedreno, and compile tested following gallium drivers: nouveau,svga,virgl,r600,r300,radeonsi,swrast,i915,ilo Signed-off-by: Stanimir Varbanov <[email protected]> Reviewed-by: Emil Velikov <[email protected]>
* gallium: Add a pipe cap for whether primitive restart works for patches.Kenneth Graunke2016-05-231-0/+1
| | | | | | | | | | | | | | | Some hardware supports primitive restart on patch primitives, and other hardware does not. Modern GL and ES include a query for this feature; adding a capability bit will allow us to answer it. As far as I know, AMD hardware does not support this feature, while NVIDIA and Intel hardware does. However, most Gallium drivers do not appear to support tessellation shaders yet. So, I've enabled it for nvc0 and disabled it everywhere else.

* vc4: Size transfer temporary mappings appropriately for full maps of 3D.Eric Anholt2016-05-181-2/+2
| | | | | | | | | We don't really support reading/writing of 3D textures since the hardware doesn't do 3D, but we do need to make sure that a pipe_transfer for them has enough space to store the image. This was previously not a problem because the state tracker only mapped a slice at a time until fb9fe352ea41c7e3633ba2c483c59b73c529845b. Fixes glean glsl1 tests, which all have setup of a 3D texture at the start.
* vc4: Add support for vertex color clamping in the rasterizer.Eric Anholt2016-05-173-1/+6
| | | | | This gets us precompile of vertex shaders at the state tracker level as well.
* vc4: Move tgsi_to_nir to precompile time.Eric Anholt2016-05-171-12/+15
| | | | | Now we have an immutable nir shader in our shader's CSO that we can clone and lower/optimize.
* vc4: Mark the driver as supporting fragment color clamping in rast.Eric Anholt2016-05-171-1/+1
| | | | | | | We always clamp fragment colors, since they're always 8-bit unorm, so there's no need to have us compile separate shaders based on GL_ARB_color_buffer_float. This gives us precompilation of fragment programs to the vc4_shader_state_create() level.
* vc4: Enable sharing shaders across contexts.Eric Anholt2016-05-172-2/+3
| | | | | | This allows the same pipe_shader_state to be referenced from multiple contexts. Since our pipe_shader_state is treated as immutable (other than the variant number) within the driver, this is no problem.
* vc4: Switch to using nir_load_front_face.Eric Anholt2016-05-172-9/+18
| | | | | | | | This will be generated by glsl_to_nir, and it turns out that this is a more code-efficient path than the floating point math, anyway. No change on shader-db, but drops an instruction in piglit's glsl-fs-frontfacing.
* vc4: Drop the dead export_linkage array.Eric Anholt2016-05-171-5/+0
| | | | This came from deriving from freedreno.
* vc4: Fix a -Wformat-security warning.Eric Anholt2016-05-171-1/+1
| | | | | This is apparently enabled as an error in Android builds, and the compiler can't tell that the return value is safe.
* gallium: Add a pipe cap for arb_cull_distanceTobias Klausmann2016-05-141-0/+1

* vc4: Add support for loading immediate values in QIR.Eric Anholt2016-05-064-0/+32
| | | | | | | This will be used for resetting the uniform stream in the presence of branching, but may also be useful as an optimization to reduce how many uniforms we have to copy out per draw call (in exchange for increasing icache pressure).
* vc4: Make vc4_qpu_validate() produce more verbose failures.Eric Anholt2016-05-061-35/+71
| | | | | | Seeing the expansion of a QPU_GET_FIELD in an assert isn't very informative, and it's hard find what's going wrong without getting a dump of the instruction that failed.
* vc4: Add a small QIR validate pass.Eric Anholt2016-05-064-0/+127
| | | | | This has caught a couple of bugs during loop development so far, and I should probably have written it long ago.
* vc4: Fix the src count on exp2/log2.Eric Anholt2016-05-061-2/+2
| | | | Found by the upcoming QIR validate pass.
* vc4: Reuse QPU disasm's cond flags in QIR.Eric Anholt2016-05-063-27/+46
| | | | In the process, this made me flatten out the "%s%s%s%s" fprintf arguments.
* vc4: When emitting an instruction to an existing temp, mark it non-SSA.Eric Anholt2016-05-061-0/+2
| | | | Prevents a bug in the later control-flow support series.
* vc4: Make sure that we don't overwrite the signal for PROG_END.Eric Anholt2016-05-061-0/+8
| | | | | | | | We should have already emitted a NOP due to the last instruction being a TLB or VPM write. However, if you disable dead code elimination then you might get dead code at the end, and that dead code might have the signal bits set to something non-default, at which point you die in assertion failure.

* vc4: Use NIR lowering for sRGB decode.Eric Anholt2016-05-022-40/+3
| | | | | This should get us the same decode code generated, but with a lot less custom code in the driver.
* vc4: Just use NIR lowering for texture projection.Eric Anholt2016-05-021-15/+3
| | | | | This means doing Newton-Raphson on the RCP, but it's probably actually a good thing to be accurate on.
* vc4: Scalarize phi nodes as well.Eric Anholt2016-05-021-0/+1
| | | | | This makes fewer programs with loops assertion fail, replacing them with the rendering failure warning.
* vc4: Add whitespace after each program stage dump.Eric Anholt2016-05-022-0/+3
| | | | | In particular it's been hard to find the point where we switch from dumping pre-optimization QIR and post-optimization QIR.
* vc4: Remove the CSE pass.Eric Anholt2016-05-024-162/+0
| | | | | | It's not doing anything according to shader-db now that we're using NIR. It would have had to be reworked significantly anyway, to handle control flow.
* vc4: Emit only one FRAG_Z or FRAG_W QIR opcode.Eric Anholt2016-05-021-2/+19
| | | | | | We were generating piles of FRAG_W for interpolation, only to CSE them away immediately. Since this is the only thing that CSE is doing for us any more, just avoid making the CSE work necessary.
* vc4: Use the NIR cubemap normalization instead of our own.Eric Anholt2016-05-021-6/+1
| | | | | | | This is one of two uses of the current QIR CSE pass according to shader-db. The NIR pass means that we'll end up doing Newton-Raphson on our RCP, which we weren't doing before, but that's probably actually a good thing.
* vc4: Drop the support for DCE of texture instructions.Eric Anholt2016-05-021-22/+1
| | | | | Now that we're using NIR for our optimization, there's no need for this tricky code.

* vc4: Make sure we recompile when sample_mask changes.Eric Anholt2016-04-221-0/+1
| | | | | | | Part of fixing piglit EXT_framebuffer_multisample/sample-coverage inverted (there is also a bug with RCL tiled blits) Cc: "11.1 11.2" <[email protected]>
* vc4: Fix validation of full res tile offset if used for non-MSAA.Eric Anholt2016-04-223-2/+14
| | | | | | There's no reason we couldn't do non-MSAA full resolution tile buffer load/stores, but we would have claimed buffer overflow was being attempted. Nothing does this currently.
* vc4: Only do MSAA FB operations if the FB is MSAA.Eric Anholt2016-04-221-5/+8
| | | | | I noticed this as a problem with ET:QW traces emitting coverage code when the framebuffer was supposed to be single sampled.
* vc4: Fix tests for format supported with nr_samples == 1.Eric Anholt2016-04-221-3/+4
| | | | | | | | | | This was a bug from the MSAA enabling. Tests for surfaces with nr_samples==1 instead of 0 (generally GL renderbuffers) would incorrectly fail out. Fixes the ARB_framebuffer_sRGB piglit tests other than srgb_conformance. Cc: "11.1 11.2" <[email protected]>
* vc4: Don't try to blit from MSAA surfaces with mismatched width to dst.Eric Anholt2016-04-221-11/+14
| | | | | | | | | I had made the previous blit fix non-MSAA only because I was thinking about how the hardware infers stride from the RENDERING_CONFIG packet. However, I'm also inferring the stride for both MSAA src and dst in vc4_render_cl.c from the width argument in the ioctl. Fixes 15 EXT_framebuffer_multisample piglit tests.
* gallium: add bool return to pipe_context::end_queryNicolai Hähnle2016-04-211-1/+2

* vc4: Fix fbo-generatemipmap-formats for NPOT.Eric Anholt2016-04-181-0/+20
| | | | | | | Single-sampled texture miplevels > 1 are stored in POT-aligned areas, but we only get one value to control the stride of the src and dst for single sampled buffers. A RCL tile blit from level != 1 to level == 0 would therefore load from the wrong stride.
* vc4: Remove unused "immediates" fieldEric Anholt2016-04-181-1/+0
| | | | This was for TGSI, which we no longer have to deal with.
* vc4: Add support for rendering to cube map surfaces.Eric Anholt2016-04-181-1/+2

* vc4: Don't flush on read-only access of buffers read by the CL.Eric Anholt2016-04-183-7/+16
| | | | | | Fixes piglit mixed-immediate-and-vbo, and may significantly improve performance of applications that store a 4-byte IB in the same VBO as vertex data.
* vc4: Sanity check that flushes don't happen between state emit and draw.Eric Anholt2016-04-181-0/+7
| | | | | | Catches the cause of failure in arb_vertex_buffer_object-mixed-immediate-and-vbo, I've had this class of failure before, and it probably won't be the last time.
* vc4: Sanity check strides for imported BOs.Eric Anholt2016-04-181-5/+18
| | | | | | | If we're going to sample from or render to them at some particular size, we'd better make sure that they actually are that size. Causes some tests under simulation to generate appropriate error messages instead of failures.
* vc4: Fix subimage accesses to LT textures.Eric Anholt2016-04-151-4/+4
| | | | | | | | | | | | | This code started out like the T case, iterating over utile offsets, but I had partially switched it to iterating over pixel offsets. I hadn't caught this before because it's unusual to do piecemeal uploads to small textures. Fixes bad text rendering in QT5 apps, which use a 256x16 glyph cache. Also fixes 6 piglit tests related to glTexSubImage() and glGetTexSubImage(). Cc: "11.1 11.2" <[email protected]>
