* anv: rework queries writes to ensure ordering memory writesLionel Landwerlin2019-05-081-17/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use a mix of MI & PIPE_CONTROL commands to write our queries' data (results & availability). Those commands' memory write order is not guaranteed with regard to their order in the command stream, unless CS stalls are inserted between them. This is problematic for 2 reasons : 1. We copy results from the device using MI commands even though the values are generated from PIPE_CONTROL, meaning we could copy unlanded values into the results and then copy the availability that is inconsistent with the values. 2. We allow the user to poll on the availability values of the query pool from the CPU. If the availability lands in memory before the values then we could return invalid values. This change does 2 things to address this problem : - We use either PIPE_CONTROL or MI commands to write both queries values and availability, so that the ordering of the memory writes guarantees that if availability is visible, results are also visible. - For the occlusion & timestamp queries we apply a CS stall before copying the results on the device, to ensure copying with MI commands see the correct values of previous PIPE_CONTROL writes of availability (required by the Vulkan spec).

* radv: call constant folding before opt algebraicTimothy Arceri2019-05-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The pattern of calling opt algebraic first seems to have originated in i965. The order in OpenGL drivers generally doesn't matter because the GLSL IR optimisations do constant folding before opt algebraic. However in Vulkan drivers calling opt algebraic first can result in missed constant folding opportunities. vkpipeline-db results (VEGA64): Totals from affected shaders: SGPRS: 3160 -> 3176 (0.51 %) VGPRS: 3588 -> 3580 (-0.22 %) Spilled SGPRs: 52 -> 44 (-15.38 %) Spilled VGPRs: 0 -> 0 (0.00 %) Private memory VGPRs: 0 -> 0 (0.00 %) Scratch size: 12 -> 12 (0.00 %) dwords per thread Code Size: 261812 -> 261036 (-0.30 %) bytes LDS: 7 -> 7 (0.00 %) blocks Max Waves: 346 -> 348 (0.58 %) Wait states: 0 -> 0 (0.00 %) Reviewed-by: Samuel Pitoiset <[email protected]> Reviewed-by: Bas Nieuwenhuizen <[email protected]>

* gallivm: fix broken 8-wide s3tc decodingRoland Scheidegger2019-05-071-17/+15
| | | | | | | | | | | | | | | | | | Brian noticed there was an uninitialized var for the 8-wide case and 128 bit blocks, which made it always crash. Likewise, the 64bit block case had another crash bug due to type mismatch. Color decode (used for all s3tc formats) also had a bogus shuffle for this case, leading to decode artifacts. Fix these all up, which makes the code actually work 8-wide. Note that it's still not used - I've verified it works, and the generated assembly does look quite a bit simpler actually (20-30% less instructions for the s3tc decode part with avx2), however in practice it still seems to be sligthly slower for some unknown reason (tested with openarena) on my haswell box, so for now continue to split things into 4-wide vectors before decoding.

* freedreno/ir3: move const_state to ir3_shaderRob Clark2019-05-0710-30/+33
| | | | | | | | | | | | | | | | | | | For a6xx, we construct/emit a single VS const state used for both binning pass and draw pass. So far we were mostly getting lucky that there were not (obvious) mismatches between the const_state (like different lowered immediates) between the binning and draw pass VS ir3_shader_variant. And I guess this situation will come up more as GS and tess is added into the equation. Since really everything about the const state is not specific to the variant, move this. The main exception is lowered immediates, but these are the last to appear in the layout, and it doesn't hurt for each new shader variant to just append any immed's it lowers to the end of the immediate state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are tests in CTS for alpha to coverage without a color attachment that are failing. This happens because we remove the shader color outputs when we don't have a valid color attachment for them, but when alpha to coverage is enabled we still want to preserve the the output at location 0 since we need the alpha component. In that case we will also need to create a null render target for RT 0. v2: - We already create a null rt when we don't have any, so reuse that for this case (Jason) - Simplify the code a bit (Iago) v3: - Take alpha to coverage from the key and don't tie this to depth-only rendering only, we want the same behavior if we have multiple render targets but the one at location 0 is not used. (Jason). - Rewrite commit message (Iago) v4: - Make sure we take into account the array length of the shader outputs, which we were no handling correctly either and make sure we also create null render targets for any invalid array entries too. v5: - Simplify removal of unused outputs by using rt_used[] so we don't have to special case alpha to coverage there too.

* nir/algebraic: Reassociate open-coded flrp(1, b, c)Ian Romanick2019-05-061-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a previous verion of this patch, Jason commented, "Re-associating based on whether or not something has a constant value of 1.0 seems a bit sneaky. I think it's well within the rules but it seems like something that could bite you." That is possibly true. The reassociation will generate different results if fabs(b) >= 2**24 and fabs(c) < 0.5. The delta increases as fabs(c) approaches 0. However, i965 has done this same reassociation indirectly for years. We would previously allow nir_op_flrp on all pre-Gen11 hardware even though Gen4 and Gen5 do not have a LRP instruction. Optimizations in nir_opt_algebraic would convert expressions like a+c(b-a) into flrp(a, b, c). On Gen7+, the hardware performs the same arithmetic as a(1-c)+bc. Gen6 seems to implement LRP as a+c(b-a). On Gen4 and Gen5, we would lower LRP to a sequence of instructions that implement a(1-c)+bc. The lowering happens after all constant folding, so we would litterally generate a 1+(-1) instruction sequence in this scenario: one instruction to load either 1 or -1 in a register, and another instruction to add either -1 or 1 to it. This patch just cuts out the middle man. Do the reassociation that we've always done, but do it explicitly at a time when we can benefit from other optimizations. A few cases that were hurt by "nir: Lower flrp(±1, b, c) and flrp(a, ±1, c) differently" are restored by this patch. This includes a few shaders in ET:QW. I tried a similar thing for open-coded flrp(-1, b, c), and it hurt instructions on 35 shaders for ILK without helping any. The helped / hurt cycles was about even.

| | | | | | | | | | | | | | | | | | | | | | | | | | I tried to be very careful while updating all the various drivers, but I don't have any of that hardware for testing. :( i965 is the only platform that sets always_precise = true, and it is only set true for fragment shaders. Gen4 and Gen5 both set lower_flrp32 only for vertex shaders. For fragment shaders, nir_op_flrp is lowered during code generation as a(1-c)+bc. On all other platforms 64-bit nir_op_flrp and on Gen11 32-bit nir_op_flrp are lowered using the old nir_opt_algebraic method. No changes on any other Intel platforms. v2: Add panfrost changes.

| | | | | | | | | | | | | | | | | This commit does a fairly large cleanup of blend descriptors, although there should not be any functional changes. In particular, we split apart the Midgard and Bifrost blend descriptors, since they are radically different. From there, we can identify that the Midgard descriptor as previously written was really two render targets' descriptors stuck together. From this observation, we split the Midgard descriptor into what a single RT actually needs. This enables us to correctly dump blending configuration for MRT samples on Midgard. It also allows the Midgard and Bifrost blend code to peacefully coexist, with runtime selection rather than a #ifdef. So, as a bonus, this will help the future Bifrost effort, eliminating one major source of compile-time architectural divergence. Signed-off-by: Alyssa Rosenzweig <[email protected]>
