* radeonsi: always prefer SWITCH_ON_EOP(0) on CIKMarek Olšák2014-08-094-10/+46
| | | | | | | | | | | | | | The code is rewritten to take known constraints into account, while always using 0 by default. This should improve performance for multi-SE parts in theory. A debug option is also added for easier debugging. (If there are hangs, use the option. If the hangs go away, you have found the problem.)

* u_primconvert: Copy min/max_index from the original primitive.Eric Anholt2014-08-081-4/+2
| | | | | | | | | | | | | | | | | | These values are supposed to be the minimum/maximum index values used to read from the vertex buffers. This code either copies index values out of the old IB (so, same min/max as the original draw call), or generates a new IB (using index values between the start and the start + count of the old array draw info, which just happens to be what min/max_index are set to by st_draw.c). We were incorrectly setting the max_index in the converting-from-glDrawArrays case to the start vertex plus the number of vertices generated in the new IB, which broke QUADS primitive conversion on VC4 (where max_index really has to be correct, or the kernel might reject your draw call due to buffer overflow).

* vc4: Add support for swizzles of 32 bit float vertex attributes.Eric Anholt2014-08-082-20/+73
| | | | | | | | | | | | Some tests start working (useprogram-flushverts, for example) due to getitng the right vertices now. Some that used to pass start failing with memory overflow during binning, which is weird (glsl-fs-texture2drect). And a couple stop rendering correctly (glsl-fs-bug25902). v2: Move the attribute format setup in the key from after search time to before the search. v3: Fix reading of attributes other than position (I forgot to respect attr and stored everything in inputs 0-3, i.e. position).

| | | | | | We could get undefined sources in real programs from the wild, so we'll need to turn off this debug eventually. But for now, using undefined sources is typically me just mistyping something.

* vc4: Switch to actually generating vertex and fragment shader code from TGSI.Eric Anholt2014-08-0812-247/+1243
| | | | | | | | | | | | | | | | | | This introduces an IR (QIR, for QPU IR) to do optimization on. It's a scalar, SSA IR in general. It looks like optimization is pretty easy this way, though I haven't figured out if it's going to be good for our weird register allocation or not (or if I want to reduce to basically QPU instructions first), and I've got some problems with it having some multi-QPU-instruction opcodes (SEQ and CMP, for example) which I probably want to break down. Of course, this commit mostly doesn't work, since many other things are still hardwired, like the VBO data. v2: Rewrite to use a bunch of helpers (qir_OPCODE) for emitting QIR instructions into temporary values, and make qir_inst4 take the 4 args separately instead of an array (all later callers wanted individual args).
* vc4: Start converting the driver to use vertex shaders.Eric Anholt2014-08-083-45/+177
| | | | | | | | Note: This is the cutoff point where I switched from developing primarily on the Pi to developing o the simulator. As a result, from this point on the code is untested on the Pi (the kernel code I have currently wasn't rendering anything at this commit, though the simulator renders successfully, suggesting kernel bugs).
* vc4: Initial skeleton driver import.Eric Anholt2014-08-0833-0/+4608
| | | | | | | | | | | | | | | | | | | This mostly just takes every draw call and turns it into a sequence of commands that clear the FBO and draw a single shaded triangle to it, regardless of the actual input vertices or shaders. I copied the initial driver skeleton mostly from freedreno, and I've preserved Rob Clark's copyright for those. I also based my initial hardcoded shaders and command lists on Scott Mansell (phire)'s "hackdriver" project, though the bit patterns of the shaders emitted end up being different. v2: Rebase on gallium megadrivers changes. v3: Rebase on PIPE_SHADER_CAP_MAX_CONSTS change. v4: Rely on simpenrose actually being installed when building for simulation. v5: Add more header duplicate-include guards. v6: Apply Emil's review (protection against vc4 sim and ilo at the same time, and dropping the dricommon drm bits) and fix a copyright header (thanks, Roland)

* draw: don't use clipvertex output if user plane clipping is disabledRoland Scheidegger2014-08-091-2/+2
| | | | | | | | | | The non-llvm path made sure that both clip and pre_clip_pos point to the data output by position, not clipvertex, if user based clipping is disabled. However, the llvm path did not, which apparently led to failures if gl_ClipVertex was written but user plane clipping not enabled (bug 80183). Why I have no idea really, but just make it match the non-llvm behavior... Reviewed-by: Brian Paul <[email protected]>
* gallivm: Handle MSAA textures in emit_fetch_texelsDarius Goad2014-08-081-2/+7

* draw: hack around weird primitive id input in gsRoland Scheidegger2014-08-083-5/+21
| | | | | | | | | | | | | | | | | | | | | | The distinction between system values and ordinary inputs is not very obvious in gallium - further fueled by the fact that they use the same semantic names. Still, if there's any value which imho really is a system value, it's the primitive id input into the gs (while earlier (tessleation) stages could read it, it is _always_ generated by the system). For some odd reason though (which I'd classify as a bug but seems too complicated to fix) the glsl compiler in mesa treats this as an ordinary varying, and everything else after that (including the state tracker and other drivers) just go along with that. But input fetching in gs for llvm based draw was definitely limited to the ordinary (2-dimensional) inputs so only worked with other state trackers, the code was also additionally relying on tgsi_scan_shader filling uses_primid correctly which did not happen neither (would set it only for all stages if it was a system value, but only set it for the fragment shader if it was an input value).

* ilo: break down the format tableChia-I Wu2014-08-081-299/+431
| | | | | | | The PRMs no longer have a single table for format capabilities. Multiple tables take up less space, and are easier to maintain. Encode typed write information while at it.
* draw: fix clipvertex trouble if position comes from gsRoland Scheidegger2014-08-061-1/+5
| | | | | | | | | | | | | | | If the vertex shader has no position but the gs has, the clipvertex output was -1 (because it's the same as vs position in this case if there's no explicit clipvertex output). This caused crashes (or assertion failures) in clipping since in the end position (which came from gs) was different from cv (-1) and we then tried to use the bogus cv input. Rather than just test for -1 cv value in clipping, make it explicitly return the position output of the gs instead which seems cleaner (since we really don't want to use the clipvertex value from the vs (it could be a valid value in the (unsupported) case of vs writing clipvertex but still using a gs). This fixes piglit shader_runner clip-distance-out-values.shader_test. Reviewed-by: Zack Rusin <[email protected]>
* draw: don't run pipeline stages when gs has no position outputRoland Scheidegger2014-08-062-1/+5
| | | | | | | | | | | | | | | | The clip stage may crash if there's no position output, for this reason code was added to avoid running the pipeline stages in this case (c7c7186045ec617c53f7899280cbe12e59503e4d). However, this failed to actually work when there was a geometry shader, since unlike the vertex shader it did not initialize the position output to -1, hence the code trying to detect this didn't trigger. So simply initialize the position output to -1 just like the vs does. This fixes piglit glsl-1.50-transform-feedback-type-and-size (segfault->pass). clip-distance-out-values.shader_test goes from segfault to assertion failure, suggesting more fixes are needed, no other piglit changes.
