* gallivm: simplify sampler interfaceRoland Scheidegger2015-03-316-271/+218
| | | | | | | | | | | | | | | | | | This has got a bit out of control with more and more parameters added. Worse, whenever something in there changes all callees have to be updated for that, even though they don't really do much with any parameter in there except pass it on to the actual sampling function. Hence simply put almost everything into a struct. Also instead of relying on some arguments being NULL, be explicit and set this in a key (which is just reused for function generation for simplicity). (The code still relies on them being NULL in the end for now.) Technically there is a minimal functional change here for shadow sampling: if shadow sampling is done is now determined explicitly by the texture function (either sample_c or the gl-style tex func inherit this from target) instead of the static texture state. These two should always match, however. Otherwise, it should generate all the same code. Reviewed-by: Jose Fonseca <[email protected]>

| | | | | | | | This cleans up more instructions generated by uniform array indexing multiplies. total instructions in shared programs: 39989 -> 39961 (-0.07%) instructions in affected programs: 896 -> 868 (-3.12%)

| | | | | | | | | | | | This cleans up some pointless operations generated by the in-driver mul24 lowering (commonly generated by making a vec4 index for a matrix in a uniform array). I could fill in other operations, but pretty much anything else ought to be getting handled at the NIR level, I think. total uniforms in shared programs: 13423 -> 13421 (-0.01%) uniforms in affected programs: 346 -> 344 (-0.58%)
* vc4: Don't bother masking out the low 24 bits for integer multipliesEric Anholt2015-03-301-12/+8
| | | | | | | | | | The hardware just uses the low 24 lines, saving us an AND to drop the high bits. total uniforms in shared programs: 13433 -> 13423 (-0.07%) uniforms in affected programs: 356 -> 346 (-2.81%) total instructions in shared programs: 40003 -> 39989 (-0.03%) instructions in affected programs: 910 -> 896 (-1.54%)
* vc4: Make integer multiply use 24 bits for the low parts.Eric Anholt2015-03-301-5/+5
| | | | | The hardware uses the low 24 bits in integer multiplies, so we can have fewer high bits (and so probably drop them more frequently).

| | | | | | | | | | | The division is probably a holdover from the days when the fixed point inline functions generated by headergen were broken.

* freedreno/a3xx: fix 3d texture layoutIlia Mirkin2015-03-282-7/+16
| | | | | | | | | | | | | The SZ2 field contains the layer size of a lower miplevel. It only contains 4 bits, which limits the maximum layer size it can describe. In situations where the next miplevel would be too big, the hardware appears to keep minifying the size until it hits one of that size. Unfortunately the hardware's ideas about sizes can differ from freedreno's which can still lead to issues. Minimize those by stopping to minify as soon as possible.

* llvmpipe: simplify address calculation for 4x4 blocksRoland Scheidegger2015-03-284-76/+35
| | | | | | | | | | | | | | These functions looked quite complicated, even though what they actually did was trivial (ever since we dropped swizzled rendering). Also drop lookup of format block per bytes done for each block, and do it once per scene instead. This improves everybody's favorite "benchmark" by 3% or so, though lp_rast_shade_quads_all() which calls this shows up still quite high for a function which does little more than call the jit function. (This would most likely be much better handled by the jit function itself, the strides are passed through anyway already, though for being able to handle layers it would definitely add some complexity.)

* gallivm: fix texture function name (key) when using txf/ldRoland Scheidegger2015-03-281-2/+5
| | | | | | | | | | When using the texel fetch functions rather than ordinary texturing, the arguments are all int vecs instead of float vecs, not to mention the actual function would look completely different. Hence this must be included in the texture function name (which serves as the key) otherwise things crash badly when a shader accesses the same texture and sampler unit with both txf/ld and ordinary texturing instructions with otherwise matching keys.

* gallivm: use llvm function calls for texturing instead of inliningRoland Scheidegger2015-03-272-26/+438
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are issues with inlining everything, most notably llvm will use much more memory (and be slower) when compiling. Ideally we'd probably use functions for shader functions too but texture sampling usually is responsible for quite some IR (it can easily reach 80% of total IR instructions) so this seems like a good start. This still generates a different function for all different combinations just like before, however it is possible llvm is missing some optimization opportunities - it is believed though such opportunities should be somewhat rare, but at least for now it can still be switched off (at compile time only). It should probably make compiled code also smaller because the same function should be used for different variants in the same module (so for the opaque/partial or linear/elts variants). No piglit change (though it does indeed speed up unrealistic tests like fp-indirections2 by a factor of 30 or so). Has a small negative performance impact in openarena - I suspect this could be fixed by running some IPO passes (despite the private linkage, llvm right now does NO optimization at all wrt anything going past the call, even if there's just one caller - so things like values stored before the call and then always written by the function etc. will not be optimized away, nor will dead arguments (which we mostly shouldn't have) be eliminated, always constant arguments promoted etc.). v2: use proper return values instead of pointer function arguments. llvm supports aggregate return values, which do wonders here eliminating unnecessary stack variables - everything in fact will be returned in registers even without any IPO optimizations. It makes the code simpler too. With this I could not measure a peformance impact in openarena any longer (though since there's still no constant value propagation etc. into the tex functions this does not mean it couldn't have a negative impact elsewhere). v3: fix some minor issues suggested by Jose, and do disassembly (and the profiling) without hacks.

* gallivm: pass jit_context pointer through to samplingRoland Scheidegger2015-03-2711-112/+171
| | | | | | | | | | | | | | The callbacks used for getting the dynamic texture/sampler state were using the jit_context from the generated jit function. This works just fine, however that way it's impossible to generate separate functions for texture sampling, as will be done in the next commit. Hence, pass this pointer through all interfaces so it can be passed to a separate function (technically, it would probably be possible to extract this pointer from the current function instead, but this feels hacky and would probably require some more hacks if we'd use real functions instead of inlining all shader functions at some point). There should be no difference in the generated code for now. Reviewed-by: Jose Fonseca <[email protected]>
