* i965: Use blorp for all updownsample blitsJason Ekstrand2016-05-145-178/+10

* i965/blorp: Get rid of the blorp_prog_data_int() helperJason Ekstrand2016-05-144-26/+2
| | | | | | | | | The helper was initially created to allow us to set reasonable defaults as we mutated the brw_blorp_prog_data structure in preparation for NIR. Now that everything is going through brw_blorp_compile_nir_shader() which fully fills out the brw_blorp_prog_data structure, we don't need the helper.

| | | | | | | | NIR gets kind of awkward when you have a 3-component vector with two floats and one int. This led to us accidentally going through float for the sample index. It doesn't hurt anything but it also isn't needed. Reviewed-by: Topi Pohjolainen <[email protected]>

* nir: Add texture opcodes and source types for multisample compressionJason Ekstrand2016-05-142-0/+12
| | | | | | | | | | | Intel hardware does a form of multisample compression that involves an auxilary surface called the MCS. When an MCS is in use, you have to first sample from the MCS with a special opcode and then pass the result of that operation into the next sample instrucion. Normally, we just do this ourselves in the back-end, but we want to expose that functionality to NIR so that we can use MCS values directly in NIR-based blorp.

* i965/fs: Organize prog_data by ksp number rather than SIMD widthJason Ekstrand2016-05-1411-192/+110
| | | | | | | | | | The hardware packets organize kernel pointers and GRF start by slots that don't map directly to dispatch width. This means that all of the state setup code has to re-arrange the data from prog_data into these slots. This logic has been duplicated 4 times in the GL driver and one more time in the Vulkan driver. Let's just put it all in brw_fs.cpp. Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | Now that we have a persample_shading bit in prog_data we can reduce the amount the state setup code needs to be looking at the GL state. In particular, it no longer pulls anything directly out of the gl_fragment_program and no longer depends on NEW_FRAGMENT_PROGRAM. Reviewed-by: Kenneth Graunke <[email protected]>
* i965/fs: Rework the persample shading key/prog_data bitsJason Ekstrand2016-05-147-56/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | This commit reworks and simplifies the way we handle persample shading in the shader key and prog_data. The previous approach had three different key bits that had slightly different and hard-to-decern meanings while the new bits are far more clear. This commit changes it to two easily understood bits that communicate everything we need: 1) key->persample_interp: means that the user has requested persample interpolation through the API. This is equivalent to having SAMPLE_SHADING enabled and having MIN_SAMPLE_SHADING_VALUE set high enough that you actually get multiple per-sample invocations. 2) key->multisample_fbo: means that the shader will be running on an actual multi-sampled framebuffer. This commit also adds a new "persample_dispatch" bit to prog_data which indicates that the shader should be run in persample mode. This way the state setup code doesn't have to look at the fragment program or GL state and can just pull that data out of the prog_data. In theory, this shuffle could mean more recompiles. However, in practice, we were shoving enough state into the key before that we were probably hitting a recompile on every per-sample shader anyway. Reviewed-by: Kenneth Graunke <[email protected]>

* i965: Fix undefined df bits in brw_reg comparisons.Kenneth Graunke2016-05-144-12/+22
| | | | | | | | | | | | | | | | | | Commit 5310bca024f77da40ea6f4c275455f9cb0528f9e added a new "double df" field to the brw_reg struct, adding an extra 4 bytes of data that isn't usually initialized (or may contain irrelevant garbage if the struct is mutated). This means that it's no longer safe to memcmp(). Instead, add a brw_regs_equal() function which ignores the extra df bits unless they matter. To keep the implementation cheap, we wrap the first set of fields in a union/struct so that we can use a single DWord comparison. v2: Drop unnecessary casts (caught by Francisco Jerez).
