* r600/shader: Initialize max_driver_temp_used correctly for the first timeGert Wollny2018-01-151-0/+1
| | | | | | | | | | | | Without this initialization the temp registers used in tgsi_declaration may used random indices, and this may result in failing translation from TGSI with an error message "GPR limit exceeded", because the random index is greater then the allowed limit implying that the shader uses more temporary registers then available.

* freedreno/ir3: "soft" depth scheduling for SFU instructionsRob Clark2018-01-141-9/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | First try with a "soft" depth, to try to schedule sfu instructions further from their consumers, but fall back to hard depth (which might result in stalling) if nothing else is avail to schedule. Previously the consumer of a sfu instruction could end up scheduled immediately after (since "hard" depth from sfu to consumer would be 0). This works because legalize pass would insert a (ss) sync bit, but it is sub-optimal since it would cause a stall. Instead prioritize other instructions for 4 cycles if they would no cause a nop to be inserted. This minimizes the stalling. There is a slight penalty in general to overall # of instructions in shader (since we could end up needing nop's later due to scheduling the "deeper" sfu consumer later), but ends up being a wash on register pressure. Overall this seems to be worth a 10+% gain in fps. Increasing the "soft" depth of sfu consumer beyond 4 helps a bit in some cases, but 4 seems to be a good trade-off between getting 99% of the gain and not increasing instruction count of shaders too much. It's possible a similar approach could help for tex/mem instructions, but the (sy) sync bit seems to trigger a switch to a different thread- group to hide memory latency (possibly with some limits depending on number of registers used?).

* freedreno/a5xx: work around SWAP vs TILE_MODE constraintRob Clark2018-01-141-0/+20
| | | | | | | | If the blit isn't changing format, but is changing tiling, just lie and call things ARGB (since the exact component order doesn't matter for a tiling blit). Signed-off-by: Rob Clark <[email protected]>
* freedreno/a5xx: texture tilingRob Clark2018-01-1416-25/+339
| | | | | | | | | | | | | | | | | | | | | | | | | | Overall a nice 5-10% gain for most games. And more for things like glmark2 texture benchmark. There are some rough edges. In particular, the hardware seems to only support tiling or component swap. (Ie. from hw PoV, ARGB/ABGR/RGBA/ BGRA are all the same format but with different component swap.) For tiled formats, only ARGB is possible. This isn't a big problem for *sampling* since we also have swizzle state there (and since util_format_compose_swizzles() already takes into account the component order, we didn't use COLOR_SWAP for sampling). But it is a problem if you try to render to a tiled BGRA (for example) surface. The next patch introduces a workaround for blitter, so we can generate tiled textures in ABGR/RGBA/BGRA, but that doesn't help the render- target case. To handle that, I think we'd need to keep track that the tiled format is different from the linear format, which seems like it would get extra fun with sampler views/etc. So for now, disabled by default, enable with FD_MESA_DEBUG=ttile. In practice it works fine for all the games I've tried, but makes piglit grumpy. Signed-off-by: Rob Clark <[email protected]>

* util: use faster zlib's CRC32 implementaionGrazvydas Ignotas2018-01-141-0/+13
| | | | | | | | | | | | | | | | | | | | zlib provides a faster slice-by-4 CRC32 implementation than the traditional single byte lookup one used by mesa. As most supported platforms now link zlib unconditionally, we can easily use it.

* broadcom/vc5: Fix up channel swizzling for textures on 4.x.Eric Anholt2018-01-121-2/+5
| | | | | | | | I had 3.x putting swizzling in the texture state only for 16-bit texture returns, and in the shader for 32-bit. This may be due to having mixed up the return channel setup on 3.x back before I had moved it into the compiler. On 4.x, the non-border-color texwrap tests are passing nicely with both 16 and 32-bit returns with swizzling in the texture state.

* broadcom/vc5: Use THRSW to enable multi-threaded shaders.Eric Anholt2018-01-129-81/+311
| | | | | This is a major performance boost on all of V3D, but is required on V3D 4.x where shaders are always either 2- or 4-threaded.
* broadcom/vc5: Properly schedule the thread-end THRSW.Eric Anholt2018-01-122-39/+137
| | | | | | | | | | This fills in the delay slots of thread end as much as we can (other than being cautious about potential TLBZ writes). In the process, I moved the thread end THRSW instruction creation to the scheduler. Once we start emitting THRSWs in the shader, we need to schedule the thread-end one differently from other THRSWs, so having it in there makes that easy.
* broadcom/vc5: Implement GFXH-1684 workaround.Eric Anholt2018-01-124-0/+20
| | | | Apparently the VPM writes need to be flushed out before we end the shader.
* broadcom/vc5: Port drawing commands to V3D 4.x.Eric Anholt2018-01-129-20/+93
| | | | | This required extending the CL submit ioctl, because the tile alloc/state buffer setup has moved from the BCL to register writes.

* broadcom/vc5: Use a physical-reg-only register class for LDVPM.Eric Anholt2018-01-122-8/+21
| | | | | This is needed for LDVPM on V3D 4.x, but will also be needed for keeping values out of the accumulators across THRSW.
* broadcom/vc5: Use the new LDVPM/STVPM opcodes on V3D 4.1.Eric Anholt2018-01-129-51/+197
| | | | | | | | | | | Now, instead of a magic write register for VPM stores we have an instruction to do them (which means no packing of other ALU ops into it), with the ability to reorder the VPM stores due to the offset being baked into the instruction. VPM loads also gain the ability to be reordered by packing the row into the A argument. They also no longer write to the r3 accumulator, and instead must be stored to a physical register.

* broadcom/vc5: Port the simulator to support V3D 4.1Eric Anholt2018-01-129-125/+216
| | | | | | | This required moving the register accesses to a separate v3dx file, since the register definitions for each V3D version collide. It seems that initializing the v3d_hw from a file dictating 3.3 (v3d_simulator_wrapper.cpp) is safe, though.
* broadcom/vc5: Drop signal bit #defines.Eric Anholt2018-01-122-8/+0
| | | | Signals are more complicated than that, and tables ended up being better.
