* intel/fs: use pull constant locations to check for first compile of a shaderJason Ekstrand2017-11-072-2/+7
| | | | | | | | | | Before, we bailing in assign_constant_locations based on the minimum dispatch size. The more direct thing to do is simply to check for whether or not we have constant locations and bail if we do. For nir_setup_uniforms, it's completely safe to do it multiple times because we just copy a value from the NIR shader. Reviewed-by: Iago Toral Quiroga <[email protected]>
* intel/fs: Retype dest to match value in read[First]InvocationJason Ekstrand2017-11-071-4/+2
| | | | | | | | | This is what we really wanted all along. Always retyping to D works because that's what get_nir_src() always gives us, at least for 32-bit types. The SPIR-V variants of these operations accept arbitrary types and we need this if we're going to handle 64 or 16-bit values. Reviewed-by: Iago Toral Quiroga <[email protected]>
* intel/fs: Uniformize the index in readInvocationJason Ekstrand2017-11-071-1/+1
| | | | | | | | The index is any value provided by the shader and this can be called in non-uniform control flow so we can't just take component 0. Found by inspection. Reviewed-by: Iago Toral Quiroga <[email protected]>

* i965/fs/nir: Minor refactor of store_outputJason Ekstrand2017-11-071-4/+3
| | | | | | | | | | | Stop retyping the output of shuffle_64bit_data_for_32bit_write. It's always BRW_REGISTER_TYPE_D which is perfectly fine for writing out. Also, when we change get_nir_src to return something with a 64-bit type for 64-bit values, the retyping will not be at all what we want. Also, retyping the output based on src.type before we whack it back to 32 bits is a problem because the output is always 32 bits. Reviewed-by: Iago Toral Quiroga <[email protected]>
* i965/fs: Return a fs_reg from shuffle_64bit_data_for_32bit_writeJason Ekstrand2017-11-072-29/+12
| | | | | | | | | All callers of this function allocate a fs_reg expressly to pass into it. It's much easier if we just let the helper allocate the register. While we're here, we switch it to doing the MOVs with an integer type so that we don't accidentally canonicalize floats on half of a double. Reviewed-by: Iago Toral Quiroga <[email protected]>
* i965/fs/nir: Simplify 64-bit store_outputJason Ekstrand2017-11-071-19/+6
| | | | | | | | | The swizzles weren't doing any good because swiz is just XYZW. Also, we were emitting an extra set of MOVs because shuffle_64bit_data_for_32bit already does a MOV for us. Finally, the temporary was only ever used inside the inner loop so there's no need for it to actually be an array. Reviewed-by: Iago Toral Quiroga <[email protected]>
* intel/fs: Use the original destination region for int MUL loweringJason Ekstrand2017-11-071-7/+9
| | | | | | | | | Some hardware (CHV, BXT) have special restrictions on register regions when doing integer multiplication. We want to respect those when we lower to DxW multiplication. Reviewed-by: Iago Toral Quiroga <[email protected]> Cc: [email protected]

| | | | | | | | | The same workaround we need for 64-bit values on little core also takes care of the Ivy Bridge problem and does so a bit more efficiently so we can drop that code while we're here. Reviewed-by: Iago Toral Quiroga <[email protected]> Cc: [email protected]
* intel/eu: Fix broadcast instruction for 64-bit values on little-coreJason Ekstrand2017-11-071-2/+24
| | | | | | | | We're not using broadcast for any 32-bit types right now since we mostly use it for emit_uniformize on 32-bit buffer indices. However, SPIR-V subgroups are going to need it for 64-bit so let's make it work. Reviewed-by: Iago Toral Quiroga <[email protected]>

* intel/compiler: Add some restrictions to MOV_INDIRECT and BROADCASTJason Ekstrand2017-11-073-0/+20

* intel/fs: Use a pair of 1-wide MOVs instead of SEL for any/allJason Ekstrand2017-11-071-9/+33
| | | | | | | | | | | For some reason, the any/all predicates don't work properly with SIMD32. In particular, it appears that a SEL with a QtrCtrl of 2H doesn't read the correct subset of the flag register and you end up getting garbage in the second half. Work around this by using a pair of 1-wide MOVs and scattering the result. This fixes the any/all instructions for SIMD32. Reviewed-by: Matt Turner <[email protected]> Cc: [email protected]
* intel/fs: Use an explicit D type for vote any/all/eq intrinsicsJason Ekstrand2017-11-071-0/+6
| | | | | | | | | | | | | The any/all intrinsics return a boolean value so D or UD is the correct type. Unfortunately, get_nir_dest has the annoying behavior of returnning a float type by default. This causes format conversion which gives us -1.0f or 0.0f in the register. If the consumer of the result does an integer comparison to zero, it will give you the right boolean value but if we do something more clever based on the 0/~0 assumption for booleans, this will give the wrong value.

* intel/fs: Don't stomp f0.1 in SIMD16 ballotJason Ekstrand2017-11-071-2/+9
| | | | | | | | | In fragment shaders f0.1 is used for discards so doing ballot after a discard can potentially cause the discard to not happen. However, we don't support SIMD32 fragment shaders yet so this isn't a problem. Reviewed-by: Iago Toral Quiroga <[email protected]> Cc: [email protected]
* intel/fs: Use ANY/ALL32 predicates in SIMD32Jason Ekstrand2017-11-071-12/+30
| | | | | | | | | | | | We have ANY/ALL32 predicates and, for the most part, they work just fine. (See the next commit for more details.) Also, due to the way that flag registers are handled in hardware, instruction splitting is able to split the CMP correctly. Specifically, that hardware looks at the execution group and knows to shift it's flag usage up correctly so a 2H instruction will write to f0.1 instead of f0.0.

* intel/fs: Be more explicit about our placement of [un]zipJason Ekstrand2017-11-071-3/+17
| | | | | | | | | | | | | Before, we were careful to place the zip after the last of the split instructions but did unzip on-demand. This changes things so that the unzips go before all of the split instructions and the unzip comes explicitly after all the split instructions. As a side-effect of this change, we now emit the split instruction from highest SIMD group to lowest instead of low to high. We could have kept the old behavior, but it shouldn't matter and this made the code easier. Reviewed-by: Iago Toral Quiroga <[email protected]> Cc: [email protected]
* intel/fs: Pass builders instead of blocks into emit_[un]zipJason Ekstrand2017-11-071-26/+35

* intel/fs: Use a pure vertical stride for large register stridesJason Ekstrand2017-11-071-3/+13
| | | | | | | | | | | | | | Register strides higher than 4 are uncommon but they can happen. For instance, if you have a 64-bit extract_u8 operation, we turn that into UB -> UQ MOV with a source stride of 8. Our previous calculation would try to generate a stride of <32;8,8>:ub which is invalid because the maximum horizontal stride is 4. To solve this problem, we instead use a stride of <8;1,0>. As noted in the comment, this does not work as a destination but that's ok as very few things actually generate that stride.

* broadcom/vc5: Fix height padding of small UIF slices.Eric Anholt2017-11-071-1/+5
| | | | | | | | The HW doesn't pad the slice's height to make a full 4x4 group of UIF blocks. We just need to pad to columns, and the start of the next column appears in the bottom of the previous column's last block. Fixes piglit fs-textureOffset-2D.

* broadcom/genxml: Fix decoding of groups with small fields.Kenneth Graunke2017-11-071-2/+4
| | | | | | | | | | | | | | | | | Groups containing fields smaller than a byte probably not being decoded correctly. For example: <group count="32" start="32" size="4"> <field name="Vertex Element Enables" start="0" end="3" type="uint"/> </group> gen_field_iterator_next would properly walk over each element of the array, incrementing group_iter. However, the code to print the actual values only considered iter->field->start/end, which are 0 and 3 in the above example. So it would always fetch bits 3:0 of the current byte, printing the same value over and over. Cc: Eric Anholt <[email protected]>
