* main/extensions: Add early extension override structuresJordan Justen2014-06-163-0/+59
| | | | | | | | | | | | | | | | | | | | | | | During the early one_time_init phase of context creation, we initialize two global gl_extensions structures. We read the MESA_EXTENSION_OVERRIDE environment variable, and store positive and negative overrides in two structures: * struct gl_extensions _mesa_extension_override_enables * struct gl_extensions _mesa_extension_override_disables These are filled before the driver initializes extensions and constants, therefore the driver can make adjustments based on the desired overrides. This can be useful during development of a new extension where the extension is only partially ready. The driver can't actually advertise support for the extension, but if it sees that the override is set for the extension, then it can expose more supported parts of the extension, such as upgrading context constants.

* i965/vec4: Use the sampler for pull constant loads on Broadwell.Kenneth Graunke2014-06-151-8/+8
| | | | | | | | | | | | | | | | | | | | | We've used the LD sampler message for pull constant loads on earlier hardware for some time, and also were already using it for the FS on Broadwell. This patch makes us use it for Broadwell VS/GS as well. I believe that when I wrote this code in 2012, we still used the data port in some cases, and I somehow neglected to convert it while rebasing. Improves performance in GLBenchmark 2.7 Egypt by 416.978% +/- 2.25821% (n = 17). Many other applications should benefit similarly: this speeds up uniform array access in the VS, which is commonly used for skinning shaders, among other things.

* i965/vec4: Fix dead code elimination for VGRFs of size > 1.Kenneth Graunke2014-06-151-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | When faced with code such as: mov vgrf31.0:UD, 960D mov vgrf31.1:UD, vgrf30.xxxx:UD The dead code eliminator didn't consider reg_offsets, so it decided that the second instruction was writing was writing to the same register as the first one, and eliminated the first one. But they're actually different registers. This fixes INTEL_DEBUG=shader_time for vertex shaders. In the above code, vgrf31.0 represents the offset into the shader_time buffer where the data should be written, and vgrf31.1 represents the actual time data. With a completely undefined offset, results were...unexpected. I think this is probably one of the few cases (maybe only case) where we generate multiple MOVs to a large VGRF. Normally, we just use them as texturing results; the other SEND-from-GRF uses a size 1 VGRF.

* Remove _mesa_is_type_integer and _mesa_is_enum_format_or_type_integerNeil Roberts2014-06-132-36/+0
| | | | | | | | | | | | | | | | | | | | | | | The comment for _mesa_is_type_integer is confusing because it says that it returns whether the type is an “integer (non-normalized)” format. I don't think it makes sense to say whether a type is normalized or not because it depends on what format it is used with. For example, GL_RGBA+GL_UNSIGNED_BYTE is normalized but GL_RGBA_INTEGER+GL_UNSIGNED_BYTE isn't. If the normalized comment is just a mistake then it still doesn't make much sense because it is missing the packed-pixel types such as GL_UNSIGNED_INT_5_6_5. If those were added then it effectively just returns type != GL_FLOAT. That function was only used in _mesa_is_enum_format_or_type_integer. This function effectively checks whether the format is non-normalized or the type is an integer. I can't think of any situation where that check would make sense. As far as I can tell neither of these functions have ever been used anywhere so we should just remove them to avoid confusion. These functions were added in 9ad8f431b2a47060bf05517246ab0fa8d249c800.

* i965: Set the fast clear color value for texture surfacesNeil Roberts2014-06-122-2/+6
| | | | | | | | | | | | | | When a multisampled texture is used for sampling the fast clear color value needs to be programmed into the surface state. This was being left as all zeroes so if the surface was cleared to a value other than black then it wouldn't work properly. This doesn't matter for single-sample textures because in that case the MCS buffer is resolved before it is used as a texture source. https://bugs.freedesktop.org/show_bug.cgi?id=79729 Reviewed-by: Chris Forbes <[email protected]> Reviewed-by: Ian Romanick <[email protected]> Cc: "10.1 10.2" <[email protected]>

* i965: Fix Haswell discard regressions since Gen4-5 line AA fix.Kenneth Graunke2014-06-121-2/+7
| | | | | | | | | | | | | | | | In commit dc2d3a7f5c217a7cee92380fbf503924a9591bea, Iago accidentally moved fire_fb_write() above the brw_pop_insn_state(), which caused the SEND to lose its predication and change from WE_normal to WE_all. Haswell uses predicated SENDs for discards, so this broke Piglit's tests for discards. We want the Gen4-5 MOV to be uncompressed, unpredicated, and unmasked, but the actual FB write itself should respect those. So, pop state first, and force it again around the single MOV.

The only real difference was that brw_math used brw_null_reg() for src1.
