| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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]>

* 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.
