* gallium: add flush_resource context functionMarek Olšák2013-09-201-0/+6
| | | | | | | | | r600g needs explicit flushing before DRI2 buffers are presented on the screen. v2: add (stub) implementations for all drivers, fix frontbuffer flushing v3: fix galahad Signed-off-by: Marek Olšák <[email protected]>

* freedreno: fix glReadPixelsRob Clark2013-09-191-2/+2
| | | | | | | duh, we still need to flush if there are pending draws and it isn't an unsynchronized case. Signed-off-by: Rob Clark <[email protected]>
* freedreno: PIPE_TRANSFER_DISCARD_WHOLE_RESOURCERob Clark2013-09-141-17/+43
| | | | | | | When the old contents do not need to be preserved, it is faster to create a new backing bo rather than stall. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx: fix VFD_INDEX_MAX overflowRob Clark2013-09-141-1/+1
| | | | | | | max_index may be 0xffffffff. The hardware does not need 1 + max_index (although it does not hurt unless max_index wraps around to zero). Signed-off-by: Rob Clark <[email protected]>

* freedreno/a3xx: stencil fixesRob Clark2013-09-149-7/+30
| | | | | | | | For mem->gmem we don't sample depth/stencil as it's native type. So we need to setup the swizzle state for the sampler based on the format used for sampling. Signed-off-by: Rob Clark <[email protected]>
* freedreno/a3xx: alpha-testRob Clark2013-09-147-7/+29
| | | | | | | Needed by some games, like etuxracer and supertuxkart which use alpha test rather than blending, to handle texture transparency. Signed-off-by: Rob Clark <[email protected]>

* 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.

* freedreno/a3xx/compiler: ensure min # of cycles after bary instrRob Clark2013-06-211-2/+13
| | | | | | | | | | The results of a bary.f do not appear to be immediatley available, but there is no explicit sync bit. Instead the compiler must just ensure that there are a minimum number of instructions following the bary before use of the result of the bary. We aren't clever enough for that so just throw in some nop's. Signed-off-by: Rob Clark <[email protected]>

* freedreno: gmem bypassRob Clark2013-06-087-30/+168
| | | | | | | | | | | | | The GPU (at least a3xx, but I think also a2xx) can render directly to memory, bypassing tiling. Although it can't do this if blend, depth, and a few other features of the pipeline are enabled. This direct memory mode can be faster for some sorts of operations, such as simple blits. In particular, this significantly speeds up XA by avoiding to pull the entire dest pixmap into GMEM, render tiles, and write it all back out again. This should also speed up resource copy-region and blit. Signed-off-by: Rob Clark <[email protected]>
* freedreno: add a3xx supportRob Clark2013-06-0835-3/+8955
| | | | | | | | | | | | | | | | | | | | The adreno a3xx GPU is found in newer snapdragon devices, such as the nexus4. The a3xx is GLESv3 and OpenCL capable, although that is not enabled yet in gallium. Compared to a2xx, it introduces an entirely new unified shader ISA, and re-shuffles all or nearly all of the registers. The good news is that (for the most part) the registers are more orthogonal, not combining unrelated state in a single register. And that there is a lot more flexibility, so we don't need to patch and re-emit the shader like we did on a2xx. The shader compiler is currently quite dumb, there would be a lot of room for improvement with an optimizing pass. Despite that, with the a320 in my nexus4 it seems to be ~2-3x faster compared to the a220 in my HP touchpad. Signed-off-by: Rob Clark <[email protected]>
