* nir/radv: remove restrictions on opt_if_loop_last_continue()Timothy Arceri2019-04-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I implemented opt_if_loop_last_continue() I had restricted this pass from moving other if-statements inside the branch opposite the continue. At the time it was causing a bunch of spilling in shader-db for i965. However Samuel Pitoiset noticed that making this pass more aggressive significantly improved the performance of Doom on RADV. Below are the statistics he gathered. 28717 shaders in 14931 tests Totals: SGPRS: 1267317 -> 1267549 (0.02 %) VGPRS: 896876 -> 895920 (-0.11 %) Spilled SGPRs: 24701 -> 26367 (6.74 %) Code Size: 48379452 -> 48507880 (0.27 %) bytes Max Waves: 241159 -> 241190 (0.01 %) Totals from affected shaders: SGPRS: 23584 -> 23816 (0.98 %) VGPRS: 25908 -> 24952 (-3.69 %) Spilled SGPRs: 503 -> 2169 (331.21 %) Code Size: 2471392 -> 2599820 (5.20 %) bytes Max Waves: 586 -> 617 (5.29 %) The codesize increases is related to Wolfenstein II it seems largely due to an increase in phis rather than the existing jumps.

| | | | | | | | | | | | | | | | | | | With this patch, tgsi_to_nir will output NIR that is tailored to the given pipe, by reading its capabilities and adjusting the NIR code to those capabilities similarly to how glsl_to_nir works. It also adds an optimization loop that brings the output NIR in line with what glsl_to_nir outputs. This is necessary for the same reason why glsl_to_nir has its own optimization loop: currently not every driver does these optimizations yet. For uses which cannot pass a pipe_screen we also keep a variant called tgsi_to_nir_noscreen which keeps the old behavior.

* nir: Move V3D's "the shader was TGSI, ignore FS output types" flag to NIR.Eric Anholt2019-02-051-0/+3
| | | | | | | | | | | | | | Ken's rework of mesa/st builtins to NIR means that we'll have more NIR shaders with color output types that are mismatched with the render target types. Since this is behavior that GLSL doesn't require, add it as a shader_info option so the driver can know that it needs to ignore the FS output's base type in favor of the actual render target's. This prevents needing additional variants in several mesa/st paths (clear, pbo upload, pbo download), given that the driver already has to handle the variants for any TGSI being passed to it (from u_blitter, for example).

| | | | | | | | | | | | | | | | | | the naming is a bit confusing no matter how you look at it. Within SPIR-V "global" memory is memory accessible from all threads. glsl "global" memory normally refers to shader thread private memory declared at global scope. As we already use "shared" for memory shared across all thrads of a work group the solution where everybody could be happy with is to rename "global" to "private" and use "global" later for memory usually stored within system accessible memory (be it VRAM or system RAM if keeping SVM in mind). glsl "local" memory is memory only accessible within a function, while SPIR-V "local" memory is memory accessible within the same workgroup. v2: rename local to function as well v3: rename vtn_variable_mode_local as well Signed-off-by: Karol Herbst <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
* glsl_type: Add support for explicitly laid out matrices and arraysJason Ekstrand2019-01-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | SPIR-V allows for matrix and array types to be decorated with explicit byte stride decorations and matrix types to be decorated row- or column-major. This commit adds support to glsl_type to encode this information. Because this doesn't work nicely with std430 and std140 alignments, we add asserts to ensure that we don't use any of the std430 or std140 layout functions with explicitly laid out types. In SPIR-V, the layout information for matrices is applied to the parent struct member instead of to the matrix type itself. However, this is gets rather clumsy when you're walking derefs trying to compute offsets because, the moment you hit a matrix, you have to crawl back the deref chain and find the struct. Instead, we take the same path here as we've taken in spirv_to_nir and put the decorations on the matrix type itself. This also subtly adds support for strided vector types. These don't come up in SPIR-V directly but you can get one as the result of taking a column from a row-major matrix or a row from a column-major matrix.

* nir: Embed the shader_info in the nir_shader againJason Ekstrand2017-05-091-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit e1af20f18a86f52a9640faf2d4ff8a71b0a4fa9b changed the shader_info from being embedded into being just a pointer. The idea was that sharing the shader_info between NIR and GLSL would be easier if it were a pointer pointing to the same shader_info struct. This, however, has caused a few problems: 1) There are many things which generate NIR without GLSL. This means we have to support both NIR shaders which come from GLSL and ones that don't and need to have an info elsewhere. 2) The solution to (1) raises all sorts of ownership issues which have to be resolved with ralloc_parent checks. 3) Ever since 00620782c92100d77c660f9783504c6d80fa1d58, we've been using nir_gather_info to fill out the final shader_info. Thanks to cloning and the above ownership issues, the nir_shader::info may not point back to the gl_shader anymore and so we have to do a copy of the shader_info from NIR back to GLSL anyway. All of these issues go away if we just embed the shader_info in the nir_shader. There's a little downside of having to copy it back after calling nir_gather_info but, as explained above, we have to do that anyway.

* nir: Rework conversion opcodesJason Ekstrand2017-03-141-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | 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]>
