* meta: Use gl_FragColor to output color values to all the draw buffersAnuj Phogat2014-05-211-11/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _mesa_meta_setup_blit_shader() currently generates a fragment shader which, irrespective of the number of draw buffers, writes the color to only one 'out' variable. Current shader rely on an undefined behavior and possibly works by chance. From OpenGL 4.0 spec, page 256: "If a fragment shader writes to gl_FragColor, DrawBuffers specifies a set of draw buffers into which the single fragment color defined by gl_FragColor is written. If a fragment shader writes to gl_FragData, or a user-defined varying out variable, DrawBuffers specifies a set of draw buffers into which each of the multiple output colors defined by these variables are separately written. If a fragment shader writes to none of gl_FragColor, gl_FragData, nor any user defined varying out variables, the values of the fragment colors following shader execution are undefined, and may differ for each fragment color." OpenGL 4.4 spec, page 463, added an additional line in this section: "If some, but not all user-defined output variables are written, the values of fragment colors corresponding to unwritten variables are similarly undefined." V2: Write color output to gl_FragColor instead of writing to multiple 'out' variables. This'll avoid recompiling the shader every time draw buffers count is updated.

* nv50/ir: fix s32 x s32 -> high s32 multiply logicIlia Mirkin2014-05-212-11/+82
| | | | | | | | | | | | | | | | | Retrieving the high 32 bits of a signed multiply is rather annoying. It appears that the simplest way to do this is to compute the absolute value of the arguments, and perform a u32 x u32 -> u64 operation. If the arguments' signs differ, then negate the result. Since there is no u64 support in the cvt instruction, we have the perform the 2's complement negation "by hand". This logic can come into use by the IMUL_HI instruction (very unlikely to be seen), as well as from constant folding of division by a constant. Fixes dolphin's divisions by 255.

* i965/fs: Assume fragment color clamping is off when precompiling.Kenneth Graunke2014-05-211-2/+0
| | | | | | | | | | | | | | | | | | | | Modern applications frequencly use both UNORM buffers and FLOAT buffers with color clamping disabled. (FLOAT with clamping explicitly enabled and SNORM buffers appear to be less common.) We don't need to emit saturates in the fragment shader in either of the common cases. Mesa sets ctx->Color._ClampFragmentColor to false if all the color buffers are UNORM. Also, for GL_FIXED_ONLY mode (the default in legacy OpenGL), it will be false if any FLOAT buffers are bound. Since the common case is false, that should be our default. Thanks to Roland Scheidegger for pointing out some faulty logic in v1 of this patch (unnecessary code and incorrect explanations). v2: Drop superfluous code and reword commit message.

| | | | | | | | | | | | | | | | | | | | | | | In order to support the (currently unregistered) Chromium-specific EGL extension eglGetSyncValuesCHROMIUM on Intel systems, we need to import the Chromium header that defines it.

| | | | | | | | | | | | | | | | | | Separating the software fallbacks from the rest of the meta path (which is usually hardware accelerated) gives callers better control over their blitting options. For example, i965 might want to try meta blit, hardware blits, then swrast as a last resort. Splitting it makes that possible.

| | | | | | | | | | | 2ea923cf571235dfe573c35c3f0d90f632bd86d8 had the side effect of IR counting now being done after IR optimization instead of before. Some quick analysis shows that there's roughly 1.5 times more IR instructions before optimization than after, hence the effective shader cache size got quite a bit smaller. Could counter this with an increase of the instruction limit but it probably makes more sense to count them after optimizations, so move that code. Reviewed-by: Brian Paul <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | Previously, the memory context situation was a bit of a mess: fs_visitor allocated its own memory context, and freed it in the destructor. However, some data produced by fs_visitor (such as the list of instructions) needs to live beyond when fs_visitor is "done", so the caller can pass it to fs_generator. Everything worked out because brw_wm_fs_emit's fs_visitor variables happen to not go out of scope until the end of the function. But that meant that moving the declaration of, say, the SIMD16 fs_visitor instance, could cause everything to explode. Using a memory context that exists for the duration of the compile is clearer, and should be equivalent. Ultimately, we don't want to use 'c', but this matches the behavior of fs_generator and gen8_fs_generator, so it'll be simple to change later.
