* i965/nir: Make INTEL_DEBUG=ann work with NIR.Kenneth Graunke2015-04-112-1/+8
| | | | | | | | | Now that we store a copy of the NIR shader, and don't immediately free it, we can use it in annotations as well. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* i965: Create NIR during LinkShader() and ProgramStringNotify().Kenneth Graunke2015-04-119-176/+257
| | | | | | | | | | | | | | | | | | | | | | | Previously, we translated into NIR and did all the optimizations and lowering as part of running fs_visitor. This meant that we did all of that work twice for fragment shaders - once for SIMD8, and again for SIMD16. We also had to redo it every time we hit a state based recompile. We now generate NIR once at link time. ARB programs don't have linking, so we instead generate it at ProgramStringNotify time. Mesa's fixed function vertex program handling doesn't bother to inform the driver about new programs at all (which is rather mean), so we generate NIR at the last minute, if it hasn't happened already. shader-db runs ~9.4% faster on my i7-5600U, with a release build. v2: Check NirOptions != NULL in ProgramStringNotify(). Don't bother using _mesa_program_enum_to_shader_stage as we already know it. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
* nir: Store num_direct_uniforms in the nir_shader.Kenneth Graunke2015-04-112-2/+6
| | | | | | | | | | | | | | Storing this here is pretty sketchy - I don't know if any driver other than i965 will want to use it. But this will make it a lot easier to generate NIR code at link time. We'll probably rework it anyway. (Ian suggested making nir_assign_var_locations_scalar_direct_first simply modify the nir_shader's fields, rather than passing pointers to them. If this stays long term, we should do that. But Jason and I suspect we'll be reworking this area again in the near future.)

* freedreno/ir3/sched: avoid getting stuck on addr conflictsRob Clark2015-04-111-32/+42
| | | | | | | | | | | | | | | | | | When we get in a scenario where we cannot schedule any more instructions due to address register conflict, clone the instruction that writes the address register, and switch the remaining unscheduled users for the current address register over to the new clone. This is simpler and more robust than the previous attempt (which tried and sometimes failed to ensure all other dependencies of users of the address register were scheduled first).. hint it would try to schedule instructions that were not actually needed for any output value. We probably need to do the same with predicate register, although so far it isn't so heavily used so we aren't running into problems with it (yet). Signed-off-by: Rob Clark <[email protected]>

* freedreno/ir3/cp: support to swap mad src'sRob Clark2015-04-114-9/+43
| | | | | | | | | | | | | | | | For a normal MAD (ie. not MADSH), if first source is gpr and second source is const, we can swap the first two sources to avoid needing a mov instruction. This gives back the biggest advantage TGSI f/e had over NIR f/e for common shaders, since TGSI f/e had this logic in the f/e. Note that doing this in copy-prop step has the advantage that it will also work for cases like: MOV TEMP[b], CONST[x] MAD TEMP[d], TEMP[a], TEMP[b], TEMP[c] Signed-off-by: Rob Clark <[email protected]>

| | | | | | | | | | | | I guess I was looking too much at how lower_system_values worked when writing lower_idiv.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Since the rest of NIR really would rather have these as variables rather than registers, create a nir_variable per array. But rather than completely re-arrange ttn to be variable based rather than register based, keep the registers. In the cases where there is a matching var for the reg, ttn_emit_instruction will append the appropriate intrinsic to get things back from the shadow reg into the variable. NOTE: this doesn't quite handle TEMP[ADDR[]] when the DCL doesn't give an array id. But those just kinda suck, and should really go away. AFAICT we don't get those from glsl. Might be an issue for some other state tracker. v2: rework to use load_var/store_var with deref chains v3: create new "burner" reg for temporarily holding the (potentially writemask'd) dest after each instruction; add load_var to initialize temporary dest in case not all components are overwritten v4: review comments: asserts and use ttn_src_for_indirect() in ttn_array_deref() so we can drop later patch converting to use vec1 for addr reg (since ttn_src_for_indirect() handles the imov to vec1 from tgsi addr component that we want) v5: rebase: new requirements about parent mem ctx for derefs Signed-off-by: Rob Clark <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

* i965: Don't set NirOptions for stages that will use the vec4 backend.cros-mesa-10.6-vanillachadv/cros-mesa-10.6-vanillachadv/cros-gerrit-262788-baseKenneth Graunke2015-04-101-9/+6
| | | | | | | | | | | | | | | | | | | We've started using NirOptions != NULL to mean "we're using NIR for this stage." However, when INTEL_USE_NIR=1, we set it for a bunch of stages that still use the vec4 backend, and thus definitely aren't using NIR. For example, if INTEL_USE_NIR=1 we disable the GLSL IR cubemap normalization pass, even for vertex shaders and geometry shaders. This is wrong, but breaks a very uncommon case. When I started deleting GLSL IR for stages where we claimed to be using NIR, this bug quickly became apparent. For now, only set it for fragment shaders, and vertex shaders if brw->scalar_vs is set.

* gallivm: don't use control flow when doing indirect constant buffer lookupsRoland Scheidegger2015-04-093-69/+58
| | | | | | | | | | | | | | | | | | | | | | | llvm goes crazy when doing that, using way more memory and time, though there's probably more to it - this points to a very much similar issue as fixed in 8a9f5ecdb116d0449d63f7b94efbfa8b205d826f. In any case I've seen a quite plain looking vertex shader with just ~50 simple tgsi instructions (but with a dozen or so such indirect constant buffer lookups) go from a terribly high ~440ms compile time (consuming 25MB of memory in the process) down to a still awful ~230ms and 13MB with this fix (with llvm 3.3), so there's still obvious improvements possible (but I have no clue why it's so slow...). The resulting shader is most likely also faster (certainly seemed so though I don't have any hard numbers as it may have been influenced by compile times) since generally fetching constants outside the buffer range is most likely an app error (that is we expect all indices to be valid). It is possible this fixes some mysterious vertex shader slowdowns we've seen ever since we are conforming to newer apis at least partially (the main draw loop also has similar looking conditionals which we probably could do without - if not for the fetch at least for the additional elts condition.) v2: use static vars for the fake bufs, minor code cleanups Reviewed-by: Jose Fonseca <[email protected]>
