| | | | | | | | | | | | | Everything should be in place to unify code generation between Gen4-7 and Gen8+. We should be able to drop the Gen8 generators at this point. However, leave them hooked up for a brief moment, for testing and comparison purposes. Set GEN8=1 to use the old Gen8+ code generator paths.

| | | | | | | | | | | | | This improves performance in Trine 2 at 1280x720 (windowed) on "Very High" settings by 30% (in the interactive menu) to 45% (in the forest by the giant frog) on Haswell GT3e. It also now generates the same assembly on Gen7 as it does on Gen8, which always used the sampler for both types.

* i965/eu: Set src0 file to IMM on Gen8+ flow control instructions.Kenneth Graunke2014-08-121-9/+36
| | | | | | | | | | | | | | | According to the documentation, we need to set the source 0 register type to IMM for flow control instructinos that have both JIP and UIP. Out of paranoia, just make all flow control instructions use IMM; there's no benefit to using ARF anyway, and it could trouble that's difficult to diagnose. See commit 9584959123b0453cf5313722357e3abb9f736aa7, which did the analogous change in the gen8_generator code.

* i965/eu: Emulate F32TO16 and F16TO32 on Broadwell.Kenneth Graunke2014-08-121-2/+50
| | | | | | | | | | | | | | | | | When we combine the Gen4-7 and Gen8+ generators, we'll need to handle half float packing/unpacking functions somehow. The Gen8+ generator code today just emulates the behavior of the Gen7 F32TO16/F16TO32 instructions, including the align16 mode bugs. Rather than messing with fs_generator/vec4_generator, I decided to just emulate the instructions at the brw_eu_emit.c layer. v2: Change gen >= 7 asserts to gen == 7 (suggested by Chris Forbes). Fix regressions on Haswell in VS tests due to type assertions.

| | | | | | | | | | | | | | g0.5 has nothing of value to contribute to m0.5. In both the VS and GS payload, g0.5 contains the scratch space pointer - which is definitely not of any use. The GS payload also contains FFTID, but the URB write message header doesn't want FFTID. The only reason I used OR was because Eric originally requested it. On Broadwell, I used MOV, and that's worked out fine. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Chris Forbes <[email protected]> Reviewed-by: Matt Turner <[email protected]>
* i965/fs: Don't set flag_subreg_nr = 1 on predicated FB write setup.Kenneth Graunke2014-08-121-0/+1
| | | | | | | | | | | | | | | On Haswell, we implement "discard" via predicated SEND messages, using f0.1 instead of f0.0. To accomplish this, we set inst->flag_subreg to 1 on the FS_OPCODE_FB_WRITE. Most instructions using fs_inst::flag_subreg expand to a single assembly instruction. However, FS_OPCODE_FB_WRITE can generate several MOVs for setting up header information. We don't want to set flag_subreg on those, so override the default state back to 0.

* mesa/meta: Support decompressing floating-point formatsNeil Roberts2014-08-122-33/+78
| | | | | | | | | | | | | Previously the Meta implementation of glGetTexImage would fall back to _mesa_get_teximage if the texturing is not using an unsigned normalised format. However in order to support the half-float formats of BPTC textures we can make it render to a floating-point renderbuffer instead. This patch makes decompression_state have two FBOs, one for the GL_RGBA format and one for GL_RGBA32F. If a floating-point texture is encountered it will try setting up a floating-point FBO. It will now also check the status of the FBO and fall back to _mesa_get_teximage if the FBO is not complete. Reviewed-by: Ian Romanick <[email protected]>

| | | | | | | | | Once we add BPTC texture support we will need to generate mipmaps for compressed floating point textures too. Most of the code seems to already be there but it just needs a few extra lines to get it to use GL_FLOAT instead of GL_UNSIGNED_BYTE as the type for the temporary buffers.

* mesa: Add texstore functions for BPTC-compressed texturesNeil Roberts2014-08-123-0/+709
| | | | | | | | | | | | | | | | | | | | | | This adds compressors for all four of the BPTC compressed-texture formats. The compressor is written from scratch and takes a very simple approach. It always uses a single mode of the BPTC format (4 for unorm and 3 for half-floats) and picks the two endpoints by dividing the texels into those which have more or less than the average luminance of the block and then calculating an average color of the texels within each division. It's probably not really sensible to try to use BPTC compression at runtime because for example with the Nvidia offline compression tool it can take in the order of an hour to compress a full-screen image. With that in mind I don't think it's worth having a proper compressor in Mesa and this approach gives reasonable results for a usage that is basically a corner case. v2: Always use the custom compressor, even for the unorm formats. Fix the quantization step for the half-float format compressor. Fixed a typo which was breaking the right-hand edge of half-float textures with a width that isn't a multiple of four.

* mesa/format_info: Add support for the BPTC layoutNeil Roberts2014-08-121-0/+3
| | | | | | | | | | | | | | | | | | Adds the ‘bptc’ layout to get_channel_bits. The channel bits for BPTC depend on the mode but as it only has to be an approximation this sets it to 8 for the two UNORM formats and 16 for the two half-float formats. These represent the minimum number of bits of variation that can be generated by the interpolation of the two formats. This doesn't quite match what we do for S3TC which only returns 4 even though it can similarly generate 8 bits from the interpolation. However it does match what we return for ETC2. For reference, NVidia seems to return 8 bits for the UNORM formats and 32 bits for the half-float formats. v2: Change the number of bits to 8/8/8/8 for the UNORM formats and 16/16/16 for the half-float formats.
