* nir: Rework conversion opcodesJason Ekstrand2017-03-143-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | The NIR story on conversion opcodes is a mess. We've had way too many of them, naming is inconsistent, and which ones have explicit sizes was sort-of random. This commit re-organizes things and makes them all consistent: - All non-bool conversion opcodes now have the explicit size in the destination and are named <src_type>2<dst_type><size>. - Integer <-> integer conversion opcodes now only come in i2i and u2u forms (i2u and u2i have been removed) since the only difference between the different integer conversions is whether or not they sign-extend when up-converting. - Boolean conversion opcodes all have the explicit size on the bool and are named <src_type>2<dst_type>. Making things consistent also allows nir_type_conversion_op to be moved to nir_opcodes.c and auto-generated using mako. This will make adding int8, int16, and float16 versions much easier when the time comes. Reviewed-by: Eric Anholt <[email protected]>
* vc4: Fix math with a condition flag set.Eric Anholt2017-03-082-3/+18
| | | | | | | | | | | Math results land in r4, regardless of the condition. To implement them, we just need to ensure that the results are moved out of r4 (as often happens anyway, the values is live across another math instruction), so that we can attach the condition to the MOV. Fixes dEQP-GLES2.functional.shaders.random.all_features.fragment.93 and a couple others, that were assertion failing that their conditions hadn't been handled during the QIR->QPU stage.
* vc4: Fix register pressure cost estimates when a src appears twice.Eric Anholt2017-03-081-3/+13
| | | | | | | | | | This ended up confusing the scheduler for things like fabs (implemented as fmaxabs x, x) or squaring a number, and it would try to avoid scheduling them because it appeared more expensive than other instructions. Fixes failure to register allocate in dEQP-GLES2.functional.uniform_api.random.3 with almost no shader-db effects (+.35% max temps)
* vc4: Report to shader-db how many threads a fragment shader has.Eric Anholt2017-03-081-0/+7
| | | | | Doing instruction count analysis when we emit the thread switches that will save us from tons of stalls is kind of missing the point.
* Revert "vc4: Lazily emit our FS/VS input loads."Eric Anholt2017-03-084-93/+75
| | | | | | This reverts commit 292c24ddac5acc35676424f05291c101fcd47b3e. It broke a lot of GLES2 deqp, and I see at least one problem that will require some serious rework to fix.

* vc4: Lazily emit our FS/VS input loads.Eric Anholt2017-02-244-75/+93
| | | | | | | | | | | | | | | | | | | This reduces register pressure in both types of shaders, by reordering the input loads from the var->data.driver_location order to whatever order they appear first in the NIR shader. These instructions aren't reorderable at our QIR scheduling level because the FS takes two in lockstep to do an interpolation, and the VS takes multiple read instructions in a row to get a whole vec4-level attribute read. shader-db impact: total instructions in shared programs: 76666 -> 76590 (-0.10%) instructions in affected programs: 42945 -> 42869 (-0.18%) total max temps in shared programs: 9395 -> 9208 (-1.99%) max temps in affected programs: 2951 -> 2764 (-6.34%) Some programs get their max temps hurt, depending on the order that the load_input intrinsics appear, because we end up being unable to copy propagate an older VPM read into its only use.
* vc4: Refactor the load_input code out of the intrinsic code.Eric Anholt2017-02-241-25/+42
| | | | It's going gain most of ntq_setup_inputs(), so simplify it first.
* vc4: Track the last block we emitted at the top level.Eric Anholt2017-02-243-5/+10
| | | | | This will be used for delaying our VPM reads (which must be unconditional) until just before they're used.
* vc4: Emit max number of temps in the shader-db output.Eric Anholt2017-02-241-0/+23
| | | | | | | We need to be paying attention to optimization's impact on this -- even if we reduce instruction count, increasing max temps in general is likely to cause us to fail to register allocate on some shaders, which means that those won't run at all.

* vc4: Enable glSampleMask() even when !rasterizer->multisample.Eric Anholt2017-02-101-2/+1
| | | | | | | | gallium's blitter expects that it can set the sample mask even when the rasterizer doesn't have the flag on. Between this and the previous test, 10 new ext_framebuffer_multisample tests start passing.
* vc4: Respect glSampleMask() even when we're not writing color.Eric Anholt2017-02-101-3/+13
| | | | | | gallium's quad-based blitter for copying MSAA depth textures expects to be able to do 4 passes updating a sample at a time using glSampleMask, and there's no color buffer bound when it's doing that.

* vc4: Drop VS inputs to 8.Eric Anholt2017-02-101-4/+1
| | | | | | | In the hardware we only get to declare 8 vertex elements (GLES2's minimum), so we should be exposing that number here. Fixes an assertion failure in piglit texrect-many, at the expense of various GL 2.0-ish minmax tests now complaining that our count is too low.
* vc4: Avoid emitting small immediates for UBO indirect load address guards.Eric Anholt2017-02-105-4/+20
| | | | | | | | | | | | The kernel will reject our shader if we emit one here, and having 4, 8, or 12 as the top end of our UBO clamp rare is enough that it's not worth making the kernel let us. Fixes piglit fs-const-array-of-struct and fs-const-array-of-struct-of-array since recent GLSL linking changes made us get this as an indirect load of a uniform, instead of a tempoary.

| | | | | | | | | | | Nouveau does not currently have logic to implement this as a library function. Even though such a library could be written, there's no big advantage to do it that way for now given that int64 is a very uncommon use-case.

| | | | | | | | | | | | | | | | | | | Make the cap consistent with PIPE_CAP_INT64. Aside from the hypothetical case of using draw for vertex shaders (and actually caring about doubles...), every implementation supports doubles either nowhere or everywhere. Also, st/mesa didn't even check the cap correctly in all supported shader stages. While at it, add a missing LLVM version check for 64-bit integers in radeonsi. This is conservative: judging by the log, LLVM 3.8 might be sufficient, but there are probably bugs that have been fixed since then. v2: fix clover (Marek) Reviewed-by: Marek Olšák <[email protected]>

* vc4: Flip the switch to run the GLSL compiler optimization loop once.Eric Anholt2017-01-281-1/+1

The advantage is that this should significantly reduce time in the compiler.

* vc4: Use NEON to speed up utile loads on Pi2.Eric Anholt2017-01-263-18/+115
| | | | | | | | | | | | | | | | | | | We had a lot of memcpy call overhead because gpu_stride wasn't being inlined. But if you split out the stride==8 and stride==16 cases like this code does while still using memcpy, you'd no longer have glibc's NEON memcpy applied at which point we'd be doing 16 uncached reads instead of 64/(NEON memcpy granularity), for about a 30% performance hit. By hand writing the assembly, we can get a whole cacheline loaded at a time. Unfortunately, NEON intrinsics turned out to be unusable -- they didn't have the vldm instruction available. Note that, for now, the NEON code is only enabled when building for ARMv7 (Pi 2+). We may want to do runtime detection for the Raspbian case, in the future.

* vc4: Rewrite T image handling based on calling the LT handler.Eric Anholt2017-01-051-34/+75
| | | | | | | | | | | | | The T images are composed of effectively swizzled-around blocks of LT (4x4 utile) images, so we can reduce the t_utile_address() calls by 16x by calling into the simpler LT loop. This also adds support for calling down with non-utile-aligned coordinates, which will be part of lifting the utile alignment requirement on our callers and avoiding the RMW on non-utile-aligned stores.

Even if we don't trigger that, when we flush the kernel's BO allocation for the CLs or bin memory may end up throwing an error, at which point our job won't get rendered at all. Just flush early (half of maximum CMA size) so that hopefully we never get to that point.
