| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SIMD4x2 64bit data is stored in register space like this: r0.0:DF x0 y0 z0 w0 r1.0:DF x1 y1 z1 w1 When we need to write data such as this to memory using 32-bit write messages we need to shuffle it in this fashion: r0.0:DF x0 y0 x1 y1 r0.1:DF z0 w0 z1 w1 and emit two 32-bit write messages, one for r0.0 at base_offset and another one for r0.1 at base_offset+16. We also need to do the inverse operation when we read using 32-bit messages to produce valid SIMD4x2 64bit data from the data read. We can achieve this by aplying the exact same shuffling to the data read, although we need to apply different channel enables since the layout of the data is reversed. This helper implements the data shuffling logic and we will use it in various places where we read and write 64bit data from/to memory. v2 (Curro): - Use the writemask helper and don't assert on the original writemask being XYZW. - Use the Vec4 IR builder to simplify the implementation. v3 (Iago): - Use byte_offset() instead of offset(). v3: - Fix typo (Matt) - Clarify the example and fix indention (Matt).

* i965/vec4/nir: do not emit 64-bit MADIago Toral Quiroga2017-01-031-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RepCtrl=1 does not work with 64-bit operands so we need to use RepCtrl=0. In that situation, the regioning generated for the sources seems to be equivalent to <4,4,1>:DF, so it will only work for components XY, which means that we have to move any other swizzle to a temporary so that we can source from channel X (or Y) in MAD and we also need to split the instruction (we are already scalarizing DF instructions but there is room for improvement and with MAD would be more restricted in that area) Also, it seems that MAD operations like this only write proper output for channels X and Y, so writes to Z and W also need to be done to a temporary using channels X/Y and then move that to channels Z or W of the actual dst. As a result the code we produce for native 64-bit MAD instructions is rather bad, and much worse than just emitting MUL+ADD. For reference, a simple case of a fully scalarized dvec4 MAD operation requires 15 instructions if we use native MAD and 8 instructions if we emit ADD+MUL instead. There are some improvements that we can do to the emission of MAD that might bring the instruction count down in some cases, but it comes at the expense of a more complex implementation so it does not seem worth it, at least initially. This patch makes translation of NIR's 64-bit FMMA instructions produce MUL+ADD instead of MAD. Currently, there is nothing else in the vec4 backend that emits MAD instructions, so this is sufficient and it helps optimization passes see MUL+ADD from the get go.

* i965/vec4: teach register coalescing about 64-bitIago Toral Quiroga2017-01-031-3/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | Specifically, at least for now, we don't want to deal with the fact that channel sizes for fp64 instructions are twice the size, so prevent coalescing from instructions with a different type size. Also, we should check that if we are coalescing a register from another MOV we should be writing the same amount of data in both operations, otherwise we end up wiring more or less than the original instruction. This can happen, for example, when we have split fp64 MOVs with an exec size of 4 that only write one register each and then a MOV with exec size of 8 that reads both. We want to avoid the pass to think that it can coalesce from the first split MOV alone. Ideally we would like the pass to see that it can coalesce from both split MOVs instead, but for now we keep it simple. Finally, the pass doesn't support coalescing of multiple registers but in the case of normal SIMD4x2 double-precision instructions they naturally write two registers (one per vertex) and there is no reason why we should not allow coalescing in this case. Change the restriction to bail if we see instructions that write more than 8 channels, where the channels can be 32-bit or 64-bit. v2: - Make sure that scan_inst and inst write the same amount of data.

* i965/vec4: implement access to DF source components Z/WIago Toral Quiroga2017-01-031-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The general idea is that with 32-bit swizzles we cannot address DF components Z/W directly, so instead we select the region that starts at the the 16B offset into the register and use X/Y swizzles. The above, however, has the caveat that we can't do that without violating register region restrictions unless we probably do some sort of SIMD splitting. Alternatively, we can accomplish what we need without SIMD splitting by exploiting the gen7 hardware decompression bug for instructions with a vstride=0. For example, an instruction like this: mov(8) r2.x:DF r0.2<0>xyzw:DF Activates the hardware bug and produces this region: Component: x0 y0 z0 w0 x1 y1 z1 w1 Register: r0.2 r0.3 r0.2 r0.3 r1.2 r1.3 r1.2 r1.3 Where r0.2 and r0.3 are r0.z:DF for the first vertex of the SIMD4x2 execution and r1.2 and r1.3 are the same for the second vertex. Using this to our advantage we can select r0.z:DF by doing r0.2<0,2,1>.xyxy and r0.w by doing r0.2<0,2,1>.zwzw without needing to split the instruction. Of course, this only works for gen7, but that is the only hardware platform were we implement align16/fp64 at the moment. v2: Adapted to the fact that we now do this after converting to hardware registers (Iago) Reviewed-by: Matt Turner <[email protected]>
* i965/vec4: translate 64-bit swizzles to 32-bitIago Toral Quiroga2017-01-032-3/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware can only operate with 32-bit swizzles, which is a rather limiting restriction. However, the idea is not to expose this to the optimization passes, which would be a mess to deal with. Instead, we let the bulk of the vec4 backend ignore this fact and we fix the swizzles right at codegen time. At the moment the pass only needs to handle single value swizzles thanks to the scalarization pass that runs before it. Notice that this only works for X/Y swizzles. We will add support for Z/W swizzles in the next patch, since they need a bit more work. v2 (Sam): - Do not expand swizzle of 64-bit immediate values. v3: - Do this after translation to hardware registers instead of doing it right before so we don't need the force_vstride0 flag (Curro). - Squashed patch that included FIXED_GRF in the list of register files that need this translation (Iago). - Remove swizzle assignments for VGRF and UNIFORM files in convert_to_hw_regs(), they will be set by apply_logical_swizzle() (Iago).

* i965/vec4: add a scalarization pass for double-precision instructionsIago Toral Quiroga2017-01-032-0/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hardware only supports 32-bit swizzles, which means that we can only access directly channels XY of a DF making access to channels ZW more difficult, specially considering the various regioning restrictions imposed by the hardware. The combination of both things makes handling ramdom swizzles on DF operands rather difficult, as there are many combinations that can't be represented at all, at least not without some work and some level of instruction splitting depending on the case. Writemasks are 64-bit in general, however XY and ZW writemasks also work in 32-bit, which means these writemasks can't be represented natively, adding to the complexity. For now, we decided to try and simplify things as much as possible to avoid dealing with all this from the get go by adding a scalarization pass that runs after the main optimization loop. By fully scalarizing DF instructions in align16 we avoid most of the complexity introduced by the aforementioned hardware restrictions and we have an easier path to an initial fully functional version for the vector backend in Haswell and IvyBridge. Later, we can improve the implementation so we don't necessarily scalarize everything, iteratively adding more complexity and building on top of a framework that is already working. Curro drafted some ideas for how this could be done here: https://bugs.freedesktop.org/show_bug.cgi?id=92760#c82 v2: - Use a copy constructor for the scalar instructions so we copy all relevant instructions fields from the original instruction. v3: Fix indention in one switch (Matt) Reviewed-by: Matt Turner <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generally, instructions in Align16 mode only ever write to a single register and don't need any form of SIMD splitting, that's why we have never had a SIMD splitting pass in the vec4 backend. However, double-precision instructions typically write 2 registers and in some cases they run into certain hardware bugs and limitations that we need to work around by splitting the instructions so we only write to 1 register at a time. This patch implements a SIMD splitting pass similar to the one in the scalar backend. Because we only use double-precision instructions in Align16 mode in gen7 (gen8+ is fully scalar and gens < 7 do not implement fp64) the pass should be a no-op on any other generation. For now the pass only handles the gen7 restriction where any instruction that writes 2 registers also needs to read 2 registers. This affects double-precision instructions reading uniforms, for example. Later patches will extend the lowering pass adding a few more cases. v2: - Move the simd lowering pass after the main optimization loop and run copy-propagation and dce if it reports progress (Curro) - Compute number of registers written instead of fixing it to 1 (Iago) - Use group from backend_instruction (Iago) - Drop assertion that checked that we only split 8-wide instructions into 4-wide.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our current data flow analysis does not take into account that channels on 64-bit operands are 64-bit. This is a problem when the same register is accessed using both 64-bit and 32-bit channels. This is very common in operations where we need to access 64-bit data in 32-bit chunks, such as the double packing and packing operations. This patch changes the analysis by checking the bits that each source or destination datatype needs. Actually, rather than bits, we use blocks of 32bits, which is the minimum channel size. Because a vgrf can contain a dvec4 (256 bits), we reserve 8 32-bit blocks to map the channels. v2 (Curro): - Simplify code by making the var_from_reg helpers take an extra argument with the register component we want. - Fix a couple of cases where we had to update the code to the new way of representing live variables. v3: - Fix indent in multiline expressions (Matt) - Fix comment's closing tag (Matt) - Use DIV_ROUND_UP(inst->size_written, 16) instead of 2 * regs_written(inst) to avoid rounding issues.
