* i965/fs: Reimplement emit_single_fb_write() in terms of logical framebuffer ↵Francisco Jerez2015-07-292-187/+21
| | | | | | | | | | | | | writes. The only non-trivial thing it still has to do is figure out where to take the src/dst depth values from and predicate the instruction if discard is in use. The manual SIMD unrolling logic in the dual-source case goes away because this is now handled transparently by the SIMD lowering pass.

* i965/fs: Implement lowering of logical framebuffer writes.Francisco Jerez2015-07-291-1/+136
| | | | | | | | | | | | | | | | | | | | | This does essentially the same thing as fs_visitor::emit_single_fb_write(), with some slight differences: - We don't have to worry about exec_size and use_2nd_half anymore, 16-wide sources have already been lowered to 8-wide thanks to the previous commit and the manual argument unzipping is no longer required. - The src/dst_depth and sample_mask values are now explicit sources of the instruction instead of being taken from the visitor state directly. The same goes for the kill-pixel mask that will be passed to the instruction explicitly as predicate. - Everything is now done in static functions to improve encapsulation.

* i965/fs: Don't attempt to copy the useless half of oMask for SIMD8 FB writes.Francisco Jerez2015-07-291-8/+18
| | | | | | | | | | | | | | | | | | There's no need to initialize the wrong half of oMask in the payload when we're doing an 8-wide framebuffer write because it will be ignored by the hardware anyway. By doing it this way we can let the SIMD lowering pass split the sample_mask source as a regular per-channel source, otherwise we would have to introduce some sort of per-instruction source query or use fs_inst::header_size for the lowering pass to be able to find out whether some source is header-like, and leave the source untouched in that case. As a bonus this achieves the same purpose as the previous code without making use of the SET_OMASK pseudo-instruction, which will be removed in a future commit.

* i965/fs: Fix slight layering violation in emit_single_fb_writes().Francisco Jerez2015-07-291-12/+10
| | | | | | | | | | | | | | | | | In cases where the color0 argument wasn't being provided, emit_single_fb_writes() would take the alpha channel directly from the visitor state instead of taking it from its arguments. This sort of hack didn't fit nicely into the logical send-message approach because all parameters of the instruction have to be visible to the SIMD lowering pass for it to be able to split them into halves at all. Fix it by using LOAD_PAYLOAD in fs_visitor::emit_fb_writes() to provide an actual color0 vector with undefined contents except for the alpha component to match the previous behavior when no color buffers are enabled.

* i965/fs: Make sure that the type sizes are compatible during copy propagation.Francisco Jerez2015-07-291-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | It's surprising that we weren't checking for this already. A future patch will cause code like the following to be emitted: MOV(16) tmp<1>:uw, src MOV(8) dst<1>:ud, tmp<8,8,1>:ud The second MOV comes from the expansion of a LOAD_PAYLOAD header copy, so I don't have control over its types. Copy propagation will happily turn this into: MOV(8) dst<1>:ud, src Which has different semantics. Fix it by preventing propagation in cases where a single channel of the instruction would span several channels of the copy (this requirement could in fact be relaxed if the copy is just a trivial memcpy, but this case is unusual enough that I don't think it matters in practice). I'm deliberately only checking if the type of the instruction is larger than the original, because the converse case seems to be handled correctly already in the code below.

* i965/fs: Implement pass to lower instructions of unsupported SIMD width.Francisco Jerez2015-07-292-0/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This lowering pass implements an algorithm to expand SIMDN instructions into a sequence of SIMDM instructions in cases where the hardware doesn't support the original execution size natively for some particular instruction. The most important use-cases are: - Lowering send message instructions that don't support SIMD16 natively into SIMD8 (several texturing, framebuffer write and typed surface operations). - Lowering messages that don't support SIMD8 natively into SIMD16 (*cough*gen4*cough*). - 64-bit precision operations (e.g. FP64 and 64-bit integer multiplication). - SIMD32. The algorithm works by splitting the sources of the original instruction into chunks of width appropriate for the lowered instructions, and then interleaving the results component-wise into the destination of the original instruction. The pass is controlled by the get_lowered_simd_width() function that currently just returns the original execution size making the whole pass a no-op for the moment until some user is introduced.

* i965/fs: Fix return value of fs_inst::regs_read() for BAD_FILE.Francisco Jerez2015-07-291-0/+1
| | | | | | | | | | | | Typically BAD_FILE sources are used to mark a source as not present what implies that no registers are read. This will become much more frequent with logical send opcodes which have a large number of sources, many of them optionally used and marked as BAD_FILE when they aren't applicable. It will prove to be useful to be able to rely on the value of regs_read() regardless of whether a source is present or not. Reviewed-by: Jason Ekstrand <[email protected]>

* i965/fs: Add stub lowering pass for logical send-message opcodes.Francisco Jerez2015-07-292-1/+29
| | | | | | | | | | | | | | | | This pass will house ad-hoc lowering code for several send message-like virtual opcodes that will represent their logically independent arguments as separate instruction sources rather than as a single payload blob. This pass will basically just take the separate arguments that are supposed to be part of the payload and concatenate them to construct a message in the form required by the hardware. Virtual instructions in separate-source form will eventually allow some simplification of the visitor code and make several transformations easier like lowering SIMD16 instructions to SIMD8 algorithmically in cases where the hardware doesn't support the former natively.

* i965/fs: Factor out source components calculation to a separate method.Francisco Jerez2015-07-292-10/+24
| | | | | | | | | | | | | | | | | | This cleans up fs_inst::regs_read() slightly by disentangling the calculation of "components" from the handling of message payload arguments. This will also simplify the SIMD lowering and logical send message lowering passes, because it will avoid expressions like 'regs_read * REG_SIZE / component_size' which are not only ugly, they may be inaccurate because regs_read rounds up the result to the closest register multiple so they could give incorrect results when the component size is lower than one register (e.g. uniforms). This didn't seem to be a problem right now because all such expressions happen to be dealing with per-channel GRFs only currently, but that's by no means obvious so better be safe than sorry. v2: Split PIXEL_X/Y and LINTERP into separate case blocks.

| | | | | | | | | | | | | | | | | | | | | | | | The register coalesce pass wasn't rewriting the destination and sources of instructions that accessed the second half of a coalesced register previously copied with a 16-wide MOV instruction. E.g.: | ADD (16) vgrf0:f, vgrf0:f, 1.0:f | MOV (16) vgrf1:f, vgrf0:f | MOV (8) vgrf2:f, vgrf0+1:f { sechalf } would get incorrectly register-coalesced into: | ADD (16) vgrf1:f, vgrf1:f, 1.0:f | MOV (8) vgrf2:f, vgrf0+1:f { sechalf } The reason is that the mov[i] pointer was being left equal to NULL for every other register. The fact that we've made it to the rewrite loop implies that the whole register will be coalesced, so it doesn't seem right not to update something that uses it depending on whether mov[i] is NULL or not.
