2014-01-31i965: Ignore 'centroid' interpolation qualifier in case of persample shadingAnuj Phogat2-2/+3
This patch handles the use of 'centroid' qualifier with 'in' variables in a fragment shader when persample shading is enabled. Per sample shading for the whole fragment shader can be enabled by: glEnable(GL_SAMPLE_SHADING) or using {gl_SamplePosition, gl_SampleID} builtin variables in fragment shader. Explaining it below in more detail. /* Enable sample shading using OpenGL API */ glEnable(GL_SAMPLE_SHADING); glMinSampleShading(1.0); Example fragment shader: in vec4 a; centroid in vec4 b; main() { ... } Variable 'a' will be interpolated at sample location. But, what interpolation should we use for variable 'b' ? ARB_sample_shading recommends interpolation at sample position for all the variables. GLSL 400 (and earlier) spec says that: "When an interpolation qualifier is used, it overrides settings established through the OpenGL API." But, this text got deleted in later versions of GLSL. NVIDIA's and AMD's proprietary linux drivers (at OpenGL 4.3) interpolates at sample position. This convinces me to use the similar approach on intel hardware.

2014-01-31i965: Use sample barycentric coordinates with per sample shadingAnuj Phogat4-6/+29
Current implementation of arb_sample_shading doesn't set 'Barycentric Interpolation Mode' correctly. We use pixel barycentric coordinates for per sample shading. Instead we should select perspective sample or non-perspective sample barycentric coordinates. It also enables using sample barycentric coordinates in case of a fragment shader variable declared with 'sample' qualifier. e.g. sample in vec4 pos; A piglit test to verify the implementation has been posted on piglit mailing list for review. V2: Do not interpolate all the 'in' variables at sample position if fragment shader uses 'sample' qualifier with one of them. For example we have a fragment shader: #version 330 #extension ARB_gpu_shader5: require sample in vec4 a; in vec4 b; main() { ... } Only 'a' should be sampled at sample location, not 'b'.

2014-01-31i965/gen6/blorp: Emit more flushes to workaround hangsChad Versace2-15/+5
This is a squash of three related cherry-picks from master. [PATCH 1/3] i965/gen6/blorp: Set need_workaround_flush immediately after primitive This patch makes the workaround code in gen6 blorp follow the pattern established in the regular draw path. It shouldn't result in any behavioral change. On gen6, there are two places where we emit 3D_CMD_PRIM: brw_emit_prim() and gen6_blorp_emit_primitive(). brw_emit_prim() sets need_workaround_flush immediately after emitting the primitive, but blorp does not. Blorp sets need_workaround_flush at the bottom of brw_blorp_exec(). This patch moves the need_workaround_flush from brw_blorp_exec() to gen6_blorp_emit_primitive(). There is no need to set need_workaround_flush in gen7_blorp_emit_primitive() because the workaround applies only to gen6.

The art of emitting workaround flushes on Sandybridge is mysterious and not fully understood. Ken and I believe that intel_emit_post_sync_nonzero_flush() may be required when switching from regular drawing to blorp. This is an extra safety measure to prevent undiscovered difficult-to-diagnose gpu hangs. I verified that on ChromeOS, pre-patch, need_workaround_flush was not set at the top of blorp, as Paul expected.

2014-01-27draw: fix incorrect vertex size computation in LLVM drawing codeBrian Paul2-11/+30
We were calling draw_total_vs_outputs() too early. The call to draw_pt_emit_prepare() could result in the vertex size changing. So call draw_total_vs_outputs() after draw_pt_emit_prepare(). This fix would seem to be needed for the non-LLVM code as well, but it's not obvious. Instead, I added an assertion there to try to catch this problem if it were to occur there.

2014-01-25glsl: Fix chained assignments of vector channels.Kenneth Graunke1-1/+19
Simple shaders such as: void splat(vec2 v, float f) { v[0] = v[1] = f; } failed to compile with the following error: error: value of type vec2 cannot be assigned to variable of type float First, we would process v[1] = f, and transform: LHS: (expression float vector_extract (var_ref v) (constant int (1))) RHS: (var_ref f) into: LHS: (var_ref v) RHS: (expression vec2 vector_insert (var_ref v) (constant int (1)) (var_ref f)) Note that the LHS type is now vec2, not a float. This is surprising, but not the real problem. After emitting assignments, this ultimately becomes: (declare (temporary) vec2 assignment_tmp) (assign (xy) (var_ref assignment_tmp) (expression vec2 vector_insert (var_ref v) (constant int (1)) (var_ref f))) (assign (xy) (var_ref v) (var_ref assignment_tmp)) We would then return (var_ref assignment_tmp) as the rvalue, which has the wrong type---it should be float, but is instead a vec2. To fix this, we simply return (vector_extract (var_ref assignment_temp) <the appropriate channel>) to pull out the desired float value.

2014-01-25mesa: Add COMPRESSED_RGBA_S3TC_DXT1_EXT to COMPRESSED_TEXTURE_FORMATS for GLESIan Romanick1-0/+37
The ES and desktop GL specs diverge here. Yay! In desktop OpenGL, the driver can perform online compression of uncompressed texture data. GL_NUM_COMPRESSED_TEXTURE_FORMATS and GL_COMPRESSED_TEXTURE_FORMATS give the application a list of formats that it could ask the driver to compress with some expectation of quality. The GL_ARB_texture_compression spec calls this "suitable for general-purpose usage." As noted above, this means GL_COMPRESSED_RGBA_S3TC_DXT1_EXT is not included in the list. In OpenGL ES, the driver never performs compression. GL_NUM_COMPRESSED_TEXTURE_FORMATS and GL_COMPRESSED_TEXTURE_FORMATS give the application a list of formats that the driver can receive from the application. It is the *complete* list of formats. The GL_EXT_texture_compression_s3tc spec says: "New State for OpenGL ES 2.0.25 and 3.0.2 Specifications The queries for NUM_COMPRESSED_TEXTURE_FORMATS and COMPRESSED_TEXTURE_FORMATS include COMPRESSED_RGB_S3TC_DXT1_EXT, COMPRESSED_RGBA_S3TC_DXT1_EXT, COMPRESSED_RGBA_S3TC_DXT3_EXT, and COMPRESSED_RGBA_S3TC_DXT5_EXT."

2014-01-25i965: Ensure that all necessary state is re-emitted if we run out of aperture.Paul Berry3-0/+21
Prior to this patch, if we ran out of aperture space during brw_try_draw_prims(), we would rewind the batch buffer pointer (potentially throwing some state that may have been emitted by brw_upload_state()), flush the batch, and then try again. However, we wouldn't reset the dirty bits to the state they had before the call to brw_upload_state(). As a result, when we tried again, there was a danger that we wouldn't re-emit all the necessary state. (Note: prior to the introduction of hardware contexts, this wasn't a problem because flushing the batch forced all state to be re-emitted). This patch fixes the problem by leaving the dirty bits set at the end of brw_upload_state(); we only clear them after we have determined that we don't need to rewind the batch buffer.

2014-01-09i965: fold offset into coord for textureOffset(gsampler2DRect)Chris Forbes1-1/+1
The hardware is broken with nonzero texel offsets and unnormalized coordinates; instead of doing correct offsetting, we get garbage. This just extends the existing workaround for ir_txf and ir_tg4+gsampler2DRect to also consider ir_tex+gsampler2DRect. Fixes broken rendering in 'tesseract' when 'mesa_texrectoffset_bug' is not enabled; also fixes the new piglit test 'tests/spec/glsl-1.30/execution/fs-textureOffset-Rect'. Has been broken ~forever; suggesting including this in only 10.0 because the lowering pass doesn't exist in 9.2 or earlier so would require quite a different patch.

2014-01-02glsl: Fix inconsistent assumptions about ir_loop::counter.Paul Berry3-2/+9
The compiler back-ends (i965's fs_visitor and brw_visitor, ir_to_mesa_visitor, and glsl_to_tgsi_visitor) assume that when ir_loop::counter is non-null, it points to a fresh ir_variable that should be used as the loop counter (as opposed to an ir_variable that exists elsewhere in the instruction stream). However, previous to this patch: (1) loop_control_visitor did not create a new variable for ir_loop::counter; instead it re-used the existing ir_variable. This caused the loop counter to be double-incremented (once explicitly by the body of the loop, and once implicitly by ir_loop::increment). (2) ir_clone did not clone ir_loop::counter properly, resulting in the cloned ir_loop pointing to the source ir_loop's counter. (3) ir_hierarchical_visitor did not visit ir_loop::counter, resulting in the ir_variable being missed by reparenting. Additionally, most optimization passes (e.g. loop unrolling) assume that the variable mentioned by ir_loop::counter is not accessed in the body of the loop (an assumption which (1) violates). The combination of these factors caused a perfect storm in which the code worked properly nearly all of the time: for loops that got unrolled, (1) would introduce a double-increment, but loop unrolling would fail to notice it (since it assumes that ir_loop::counter is not accessed in the body of the loop), so it would unroll the loop the correct number of times. For loops that didn't get unrolled, (1) would introduce a double-increment, but then later when the IR was cloned for linking, (2) would prevent the loop counter from being cloned properly, so it would look to further analysis stages like an independent variable (and hence the double-increment would stop occurring). At the end of linking, (3) would prevent the loop counter from being reparented, so it would still belong to the shader object rather than the linked program object. Provided that the client program didn't delete the shader object, the memory would never get reclaimed, and so the shader would function properly. However, for loops that didn't get unrolled, if the client program did delete the shader object, and the memory belonging to the loop counter got re-used, this could cause a use-after-free bug, leading to a crash. This patch fixes loop_control_visitor, ir_clone, and ir_hierarchical_visitor to treat ir_loop::counter the same way the back-ends treat it: as a freshly allocated ir_variable that needs to be visited and cloned independently of other ir_variables.

2014-01-02glsl: Teach ir_variable_refcount about ir_loop::counter variables.Paul Berry2-0/+22
If an ir_loop has a non-null "counter" field, the variable referred to by this field is implicitly read and written by the loop. We need to account for this in ir_variable_refcount, otherwise there is a danger we will try to dead-code-eliminate the loop counter variable. Note: at the moment the dead code elimination bug doesn't occur due to a bug in ir_hierarchical_visitor: it doesn't visit the "counter" field, so dead code elimination doesn't treat it as a candidate for elimination. But the patch to follow will fix that bug, so we need to fix ir_variable_refcount first in order to avoid breaking dead code elimination.

Emitting flushes before depth and hiz resolves at the top of blorp's state emission fixes the hang. Marchesin and I found the fix experimentally, as opposed to adhering to a documented hardware workaround. A more minimal fix likely exists, but this gets the job done.

2014-01-02glcpp: error on multiple #else/#elif directivesErik Faye-Lund6-1/+51
The preprocessor currently accepts multiple else/elif-groups per if-section. The GLSL-preprocessor is defined by the C++ specification, which defines the following parse-rule: if-section: if-group elif-groups(opt) else-group(opt) endif-line This clearly only allows a single else-group, that has to come after any elif-groups. So let's modify the code to follow the specification. Add test to prevent regressions.
