* freedreno/a3xx: fix VS out / FS in linkingRob Clark2013-11-013-7/+47
| | | | | | | | Actually link VS out / FS in based on semantic info, keeping in mind that position/pointsize can also be an input to the FS. This fixes a few fragment shaders which were using gl_Position. Signed-off-by: Rob Clark <[email protected]>

* freedreno/a3xx/compiler: highp frag shaderRob Clark2013-11-014-12/+14
| | | | | | | | | | | | | | Fixes use of full-precision in fragment shader (ie. don't clobber r0.x since that can be used by future bary instructions for varying fetch). And makes use of full-precision the default in fragment shader (but can be overriden via FD_MESA_DEBUG=fraghalf). Seems like half precision is often not enough for texture coordinates. The blob compiler is clever enough to keep texture coords in full precision registers while using half precision for everything else. But we aren't quite that clever yet, so better to default to full precision. Signed-off-by: Rob Clark <[email protected]>

* freedreno/a3xx: fix const/rel/const-rel encodingRob Clark2013-10-244-88/+300
| | | | | | | | | | | | | | | | | | | | | | | | The encoding of constant, relative, and relative-const src registers is a bit more complex than originally thought, which gives an extra bit to encode const reg # at expense of taking a bit from relative offset. In most cases a3xx seems to actually use a scheme whereby it can encode an extra bit for const register. You have three possible encodings in thirteen bits: register: (11 bits for N.c) 00........... rN.c relative: (10 bits for N) 010.......... r<a0.x + N> 011.......... c<a0.x + N> const: (12 bits for N.c) 1............ cN.c Which means we can deal w/ more consts than previously thought.

Note: at this time, it's expected that the 'start' parameter will always be zero.

* freedreno/a3xx: use INDIRECT state load for shadersRob Clark2013-09-143-8/+29
| | | | | | | | | With a debug option to force DIRECT (mainly to make it easier for capturing cmdstream dumps). Using INDIRECT for large shaders at least makes a noticable reduction in CPU load, which helps for CPU limited games. Signed-off-by: Rob Clark <[email protected]>
* freedreno: avoid stalling at ringbuffer wraparoundRob Clark2013-09-142-22/+41
| | | | | | | | | Because of how the tiling works, we can't really flush at arbitrary points very easily. So wraparound is handled by resetting to top of ringbuffer. Previously this would stall until current rendering is complete. Instead cycle through multiple ringbuffers to avoid a stall. Signed-off-by: Rob Clark <[email protected]>
* freedreno: emit markers to scratch registersRob Clark2013-09-144-0/+33
| | | | | | | | | Emit markers by writing to scratch registers in order to "triangulate" gpu lockup position from post-mortem register dump. By comparing register values in post-mortem dump to command-stream, it is possible to narrow down which DRAW_INDX caused the lockup. Signed-off-by: Rob Clark <[email protected]>

* freedreno/a3xx: fix gpu lockup in some piglit testsRob Clark2013-09-141-1/+1
| | | | | | | | | The varying-out config comes from the inputs of the frag shader (so that we aren't exporting unneeded varyinges). The varyings-count should come from the frag shader as well, to avoid a discrepency in configuration and resulting gpu lockup. Signed-off-by: Rob Clark <[email protected]>

* freedreno/a3xx/compiler: handle sync flags betterRob Clark2013-08-291-16/+34
| | | | | | | | We need to set the flag on all the .xyzw components that are written by the instruction, not just on .x. Otherwise a later use of rN.y (for example) will not trigger the appropriate sync bit to be set. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx/compiler: better const handlingRob Clark2013-08-291-90/+121
| | | | | | | | | Seems like most/all instructions have some restrictions about const src registers. In seems like the 2 src (cat2) instructions can take at most one const, and the 3 src (cat3) instructions can take at most one const in the first 2 arguments. And so on. Handle this properly now.

* freedreno/a3xx/compiler: fix SGT/SLT/etcRob Clark2013-08-241-29/+125
| | | | | | | | | | The cmps.f.* instruction doesn't actually seem to give a float 1.0 or 0.0 output. It either needs a cov.u16f16 or add.s + sel.f16. This makes SGT/SLT/etc more similar to CMP, so handle them in trans_cmp(). This fixes a bunch of piglit tests. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx/compiler: bit of re-arrange/cleanupRob Clark2013-08-241-61/+71
| | | | | | | | It seems there are a number of cases where instructions have limitations about taking reading src's from const register file, so make get_unconst() a bit easier to use. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx/compiler: make compiler errors more usefulRob Clark2013-08-242-17/+33
| | | | | | | | | | | | | | We probably should get rid of assert() entirely, but at this stage it is more useful for things to crash where we can catch it in a debugger. With compile_error() we have a single place to set an error flag (to bail out and return an error on the next instruction) so that will be a small change later when enough of the compiler bugs are sorted. But re-arrange/cleanup the error/assert stuff so we at least get a dump of the TGSI that triggered it. So we see some useful output in piglit logs. Signed-off-by: Rob Clark <[email protected]>
* freedreno: fix segfault when no color buffer boundRob Clark2013-08-247-18/+40
| | | | | | | Don't crash when no color buffer bound. Something caught when starting to run piglit, fixes a hanful of piglit tests. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx/compiler: cat4 cannot use const reg as srcRob Clark2013-08-241-10/+27
| | | | | | | | | | | | | Category 4 instructions (rsq, rcp, sqrt, etc) seem to be unable to take a const register as src. In these cases we need to move the src to a temporary gpr first. This is the second case of such a restriction, where the instruction encoding appears to support a const src, but in fact the hw appears to ignore that bit. So split things out into a helper that can be re-used for any instructions which have this limitation. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx/compiler: use max_reg rather than file_countRob Clark2013-08-241-7/+7
| | | | | | | | | | Our current (rather naive) register assignment is based on mapping different register files (INPUT, OUTPUT, TEMP, CONST, etc) based on the max register index of the preceding file. But in some cases, the lowest used register in a file might not be zero. In which case file_count[file] != file_max[file] + 1. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx/compiler: handle saturate on dstRob Clark2013-08-241-0/+49
| | | | | | | | Sometimes things other than color dst need saturating, like if there is a 'clamp(foo, 0.0, 1.0)'. So for saturated dst add the extra instructions to fix up dst. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx/compiler: fix CMPRob Clark2013-08-241-2/+2
| | | | | | | | | | | | | | | | The 1st src to add.s needs (r) flag (repeat), otherwise it will end up: add.s dst.xyzw, tmp.xxxx -1 instead of: add.s dst.xyzw, tmp.xyzw, -1 Also, if we are using a temporary dst to avoid clobbering one of the src registers, we actually need to use that as the dst for the sel instruction.
