* i965/fs: Refactor sampler message header to duplicate less code.Kenneth Graunke2014-01-221-25/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the code to copy g0 to the message header existed in two places - one for the texture offset case, and one for any other case. By treating texture_offset as a special case of header_present, we can remove this duplication and shorten the code. Future patches which add new header fields also won't have to add additional duplication. This also clarifies a confusing construct. The old code contained: } else if (inst->header_present) { if (brw->gen >= 7) { ...explicit copy from g0 to the message header... } else { /* Set up an implied move from g0 to the MRF. */ } } This looks like it might set up an implied move on Sandybridge, which doesn't support those. However, Sandybridge only uses a message header for texture offsets, so it would never hit this code path. The new code avoids this implicit knowledge by only setting up an implied move on Gen4-5.

* intel: Fix initial MakeCurrent for single-buffer drawablesKristian Høgsberg2014-01-221-6/+4
| | | | | | | | | | | | | | | Commit 05da4a7a5e7d5bd988cb31f94ed8e1f053d9ee39 attempts to eliminate the call to intel_update_renderbuffer() in the case where we already have a drawbuffer for the drawable. Unfortunately this only checks the back left renderbuffer, which breaks in case of single buffer drawables. This means that the initial viewport will not be set in that case. Instead, we now check whether the initial viewport has not been set, in which case we call out to intel_update_renderbuffer(). https://bugs.freedesktop.org/show_bug.cgi?id=73862 Signed-off-by: Kristian Høgsberg <[email protected]>

This patch keeps _mesa_shader_stage_to_program(), since its name is more consistent with other related functions. However, it changes the signature so that it accepts an unsigned integer instead of a gl_shader_stage--this avoids awkward casts when the function is called from C++ code.

* i965: Ignore 'centroid' interpolation qualifier in case of persample shadingAnuj Phogat2014-01-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* i965: Use sample barycentric coordinates with per sample shadingAnuj Phogat2014-01-214-6/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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'.

Cases such as set A ------ ... | mov B, A -- | ... | B | A use B -- | ... | use A ------ would be considered to interfere, even though B is an unmodified copy of A whose live range fit wholly inside that of A. If no writes to A or B occur between the mov B, A and the use of B then we can safely coalesce them. Instead of removing MOV instructions, we make them NOPs and remove them at once after the main pass is finished in order to avoid recomputing live intervals (which are needed to perform the previous step). total instructions in shared programs: 1543768 -> 1513077 (-1.99%) instructions in affected programs: 951563 -> 920872 (-3.23%) GAINED: 46 LOST: 22 Reviewed-by: Jordan Justen <[email protected]>
