* gallivm: don't use control flow when doing indirect constant buffer lookupsRoland Scheidegger2015-04-091-2/+4
| | | | | | | | | | | | | | | | | | | | | | | 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]>
* llvmpipe: enable ARB_texture_gatherRoland Scheidegger2015-03-311-2/+3
| | | | | | | | | | | | Just announce support for 4 components. While here also increase the max/min texel offsets (the limit is completely artificial, was chosen because that's what other hardware did, however there's other drivers using larger limits). Over a thousand little piglits skip->pass. v2: update docs/GL3.txt Reviewed-by: Jose Fonseca <[email protected]>
* gallivm: simplify sampler interfaceRoland Scheidegger2015-03-311-26/+7
| | | | | | | | | | | | | | | | | | 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]>
* 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: pass jit_context pointer through to samplingRoland Scheidegger2015-03-273-18/+19
| | | | | | | | | | | | | | 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]>

* llvmpipe: use global llvm context for PIPE_SUBSYSTEM_EMBEDDEDRoland Scheidegger2015-03-211-0/+11
| | | | | | | | | | | | | | | | | There's 2 reasons why we'd want to use the global context: 1) There still seems to be one memory "leak" left when using multiple llvm contexts (it is not a true leak as the memory disappears into some still addressable pool but nevertheless the memory consumption grows). See http://cgit.freedesktop.org/~jrfonseca/llvm-jitstress/ 2) These contexts get kinda big - even when disposing modules etc. after compiling a shader the LLVMContext can easily be over 100kB. So when there's lots of llvm contexts arounds it adds up. The downside is that at least right now this is absolutely not thread safe, so this only works safely in environments where multiple pipe contexts are not used concurrently.

The main objective of this change is to enable Linux developers to use more of C99 throughout Mesa, with confidence that the portions that need to be built with MSVC -- and only those portions --, stay portable.

Unfortunately we still need MSVC 2008 on a few portions of the code (namely llvmpipe and its dependencies). I hope to eventually eliminate this so that we can use C99 everywhere, but there are technical/logistic challenges (specifically, newer Windows SDKs no longer bundle MSVC, instead require a full installation of Visual Studio, and that has hindered adoption of newer MSVC versions on our build processes.) Thankfully we have more directy control over our OpenGL driver, which is why we're now able to migrate to MSVC 2013 for most of the tree.

The idea is that drivers not supporting vertex ids with base vertex offset applied (so, only support d3d10-style vertex ids) will get such a d3d10-style vertex id instead - with the caveat they'll also need to handle the basevertex system value too (this follows what core mesa already does). Additionally, this is also useful for other state trackers (for instance llvmpipe / draw right now implement the d3d10 behavior on purpose, but with different semantics it can just do both). Doesn't do anything yet. And fix up the docs wrt similar values. v2: incorporate feedback from Brian and others, better names, better docs.

* llvmpipe: decrease MAX_SCENES from 2 to 1Roland Scheidegger2014-12-062-1/+13
| | | | | | | | | | | | | | | | | | Multiple scenes per context are meant to be used so a new scene can be built while another one is processed in rasterization. However, quite surprisingly, this does not actually work (and according to git log, possibly never did, though maybe it did at some point further back (5 years+) but was buggy) because we always wait immediately on the rasterizer to finish the scene when contexts (and hence setup/scene) is flushed. This means when we try to get an empty scene later, any old one is already empty again. Thus using multiple scenes is just a waste of memory (not too bad, since the additional scenes are guaranteed to be empty, which means their size ought to be one data block (64kB) plus the size of some structs), without actually really doing anything. (There is also quite some code for the whole concept of multiple scenes which doesn't really do much in practice, but keep it hoping the wait-on-scene-flush can be fixed some day.)

* llvmpipe: fix lp_test_arit denorm handlingRoland Scheidegger2014-11-251-1/+37
| | | | | | | | | | | | | | | | | | llvmpipe disables denorms on purpose (on x86/sse only), because denorms are generally neither required nor desired for graphic apis (and in case of d3d10, they are forbidden). However, this caused some arithmetic tests using denorms to fail on some systems, because the reference did not generate the same results anymore. (It did not fail on all systems - behavior of these math functions is sort of undefined when called with non-standard floating point mode, hence the result differing depending on implementation and in particular the sse capabilities.) So, for the reference, simply flush all (input/output) denorms manually to zero in this case. This fixes https://bugs.freedesktop.org/show_bug.cgi?id=67672.

* gallivm: fix alignment issue for vertex data fetchRoland Scheidegger2014-11-181-1/+2
| | | | | | | | | | | | | | We cannot guarantee that vertex buffers have the necessary alignment for fetching all AoS members at once (for instance 4x32bit XYZW data). We can however guarantee that for textures. This did not cause errors for older llvm versions but it now matters and will cause segfaults if the data happens to not be aligned. Thus we need to set alignment manually. (Note that we can't actually really guarantee data to be even element aligned due to offsets in vertex buffers being bytes and OpenGL allowing this, but it does not matter for x86 as alignment is only required for sse vectors - not sure what happens on other archs, however.)
