* i965: Lift some restrictions on dma_buf EGLImagesChad Versace2015-04-133-22/+7
| | | | | | | | | | | | | | | | | | | | | Allow glEGLImageTargetRenderbufferStorageOES and glEGLImageTargetTexture2DOES for dma_buf EGLImages if the image is a single RGBA8 unorm plane. This is safe, despite fast color clears, because i965 disables allocation of auxiliary buffers for EGLImages. Chrome OS needs this, because its compositor uses dma_buf EGLImages for its scanout buffers. Testing: - Tested on Ivybridge Chromebook Pixel with WebGL Aquarium and YouTube. - No Piglit regressions on Broadwell with `piglit run -p gbm tests/quick.py`, with my Piglit patches that update the EGL_EXT_image_dma_buf_import tests.

* i965: Disable aux buffers for EGLImage-backed miptreesChad Versace2015-04-132-5/+19
| | | | | | | | | | | | | | | | | | | | EGL does not yet have extensions to manage the flushing and invalidating of driver-internal aux buffers. So we must disable aux buffers of dma_buf-backed EGLImages in order to safely render into them. This patch is obviously needed for renderbufers. It's also needed for textures because the user can attach the texture to a framebuffer and because the driver sometimes renders to textures for internal reasons.

* i965: Add field intel_mipmap_tree::disable_aux_buffersChad Versace2015-04-132-2/+29
| | | | | | | | | | | | | | | | | | | | | | The new field disables allocation of auxiliary buffers, such as the HiZ buffer and MCS buffer. This is useful for sharing the miptree bo with an external client that doesn't understand auxiliary buffers. We need this field to safely render to a buffer that was imported with EGL_EXT_image_dma_buf_import, because EGL does not yet have extensions to manage flushing and invalidating auxiliary buffers. Nothing yet enables this field. That's left to follow-up patches.

* i965: Refactor brw_is_hiz_depth_format()Chad Versace2015-04-135-25/+30
| | | | | | | | | | | | | | | | | | | | | Every caller of this function uses it to determine if the current miptree needs a hiz buffer to be allocated. Strangely, the function doesn't take a miptree argument. So, this function effectively decides if and when a miptree's hiz buffer gets allocated without inspecting the miptree itself. Luckily, the driver behaves correctly despite the brw_is_hiz_depth_format's quirk. I will soon make some changes to the miptree that will require inspecting the miptree to determine if it needs a hiz buffer. So this patch renames brw_is_hiz_depth_format -> intel_miptree_wants_hiz_buffer and gives it a miptree parameter. This patch shouldn't change any behavior.

* i965: Create NIR during LinkShader() and ProgramStringNotify().Kenneth Graunke2015-04-117-176/+250
| | | | | | | | | | | | | | | | | | | | | | | Previously, we translated into NIR and did all the optimizations and lowering as part of running fs_visitor. This meant that we did all of that work twice for fragment shaders - once for SIMD8, and again for SIMD16. We also had to redo it every time we hit a state based recompile. We now generate NIR once at link time. ARB programs don't have linking, so we instead generate it at ProgramStringNotify time. Mesa's fixed function vertex program handling doesn't bother to inform the driver about new programs at all (which is rather mean), so we generate NIR at the last minute, if it hasn't happened already. shader-db runs ~9.4% faster on my i7-5600U, with a release build. v2: Check NirOptions != NULL in ProgramStringNotify().

| | | | | | | | | | | | | | Storing this here is pretty sketchy - I don't know if any driver other than i965 will want to use it. But this will make it a lot easier to generate NIR code at link time. We'll probably rework it anyway. (Ian suggested making nir_assign_var_locations_scalar_direct_first simply modify the nir_shader's fields, rather than passing pointers to them. If this stays long term, we should do that. But Jason and I suspect we'll be reworking this area again in the near future.)

| | | | | | | | | | | | | | | | | | | We've started using NirOptions != NULL to mean "we're using NIR for this stage." However, when INTEL_USE_NIR=1, we set it for a bunch of stages that still use the vec4 backend, and thus definitely aren't using NIR. For example, if INTEL_USE_NIR=1 we disable the GLSL IR cubemap normalization pass, even for vertex shaders and geometry shaders. This is wrong, but breaks a very uncommon case. When I started deleting GLSL IR for stages where we claimed to be using NIR, this bug quickly became apparent. For now, only set it for fragment shaders, and vertex shaders if brw->scalar_vs is set.

* i965: Do not render primitives in non-zero streams then TF is disabledIago Toral Quiroga2015-04-061-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Haswell hardware seems to ignore Render Stream Select bits from 3DSTATE_STREAMOUT packet when the SOL stage is disabled even if the PRM says otherwise. Because of this, all primitives are sent down the pipeline for rasterization, which is wrong. If SOL is enabled, Render Stream Select is honored and primitives bound to non-zero streams are discarded after stream output. Since the only purpose of primives sent to non-zero streams is to be recorded by transform feedback, we can simply discard all geometry bound to non-zero streams then transform feedback is disabled to prevent it from ever reaching the rasterization stage. Notice that this patch introduces a small change in the behavior we get when a geometry shader emits more vertices than the maximum declared: before, a vertex that was emitted to a non-zero stream when TF was disabled would still count for the purposes of checking that we don't exceed the maximum number of output vertices declared by the shader. With this change, these vertices are completely ignored and won't increase the output vertex count, making more room for other (hopefully more useful) vertices. Fixes piglit test arb_gpu_shader5-emitstreamvertex_nodraw on Haswell and Broadwell. v2 (Ken): Drop is_haswell check in favor of doing this unconditionally. Broadwell needs the workaround as well, and it doesn't hurt to do it in general. Also tweak comments - the Haswell PRM does actually mention this ("Command Reference: Instructions" page 797).

| | | | | | | | | | | | | | | | | | | | | | | | While working on NIR's memory allocation model, I realized the GLSL IR memory model was broken. During glCompileShader, we allocate everything out of the _mesa_glsl_parse_state context, and reparent it to gl_shader at the end. During glLinkProgram, we allocate everything out of a temporary context, then reparent it to the exec_list containing the linked IR. But during brw_link_shader - the driver's final opportunity to do lowering and optimization - we just allocated everything out of the permanent context given to us by the linker. That memory stayed forever. Notably, passes like brw_fs_channel_expressions cause us to churn the majority of the code, so we really want to free dead IR here.

| | | | | | | | | | | | | | | | | | | | | | | | | This allows SIMD16 mode to work for a lot more programs. Texturing is also more efficient in SIMD16 mode than SIMD8. Several messages don't actually exist in SIMD8 mode, so we did SIMD16 messages and threw away half of the data. Now we compute real data in both halves. Also, the SIMD16 "sample" message doesn't require all three coordinate components to exist (like the SIMD8 one), so we can shorten the message lengths, cutting register usage a bit. I chose to implement the visitor functionality in a separate function, since mixing true SIMD16 with SIMD8 code that uses SIMD16 fallbacks seemed like a mess. The new code bails on a few cases where we'd have to do two SIMD8 messages - we just fall back to SIMD8 for now.

| | | | | | | | | | | | | | | | | | | | | | | Gen5+ systems allow you to specify multiple shader programs - both SIMD8 and SIMD16 - and the hardware will automatically dispatch to the most appropriate one, given the number of subspans to be processed. However, that is not the case on Gen4. Instead, you program a single shader. If you enable multiple dispatch modes (SIMD8 and SIMD16), the shader is supposed to contain a series of jump instructions at the beginning. The hardware will launch the shader at a small offset, hitting one of the jumps. We've always thought that sounds like a pain, and weren't clear how it affected performance - is it worth having multiple shader types? So, we never bothered with SIMD16 until now.
