* gallium: add condition parameter to render_conditionRoland Scheidegger2013-06-184-2/+8
| | | | | | | | | | | | | For conditional rendering this makes it possible to skip rendering if either the predicate is true or false, as supported by d3d10 (in fact previously it was sort of implied skip rendering if predicate is false for occlusion predicate, and true for so_overflow predicate). There's no cap bit for this as presumably all drivers could do it trivially (but this patch does not implement it for the drivers using true hw predicates, nvxx, r600, radeonsi, no change is expected for OpenGL functionality).

* r600g: upsample and downsample MSAA resources for transfersMarek Olšák2013-06-131-79/+141
| | | | | | | | | | | We did downsample (=resolve) MSAA resources to make ReadPixels work with MSAA GLX visuals, which was enough for read-only color-only transfers. This commit makes write color transfers and depth-stencil transfers work in a similar manner. It does downsampling in transfer_map and upsampling in transfer_unmap.

* r600g/sb: fix scheduling of PRED_SET instructionsVadim Girlin2013-05-272-2/+18
| | | | | | | | | | | | | | PRED_SET instructions that update exec mask should be scheduled immediately prior to the "if-then-else" block, because any instruction that is inserted after alu clause with PRED_SET and before conditional block is also conditionally executed by hw (exec mask is already updated at that moment). Propbably it's better to make PRED_SET a part of conditional "if-then-else" block in the IR to handle this more cleanly, but for now this temporary solution should prevent the problem.

* r600g/sb: fix handling of preloaded inputs for compute shadersVadim Girlin2013-05-251-0/+4
| | | | | | | | | | For compute shaders we need to let the backend know that GPRs 0 and 1 are preloaded with some compute-specific input values, otherwise any use of these regs without previous definition is considered as undefined value and usually is simply replaced with 0.

* r600g/sb: relax register allocation for compute shadersVadim Girlin2013-05-242-2/+16
| | | | | | | | | | | | | | We have to assume that all GPRs in compute shader can be indirectly addressed because LLVM backend doesn't provide any indirect array info. That's why for compute shaders GPR array is created that covers all used GPRs (0..r600_bytecode::ngpr-1), but this seriously restricts register allocation in sb. This patch checks for actual use of indirect access in the shader and if it's not used then GPR array is not created, so that regalloc is not unnecessarily restricted.

* r600g: Correctly initialize the shader key, v2Lauri Kasanen2013-05-031-1/+2
| | | | | | | | | | | | | | | | | | | | | Assigning a struct only copies the members - any padding is left as is. Thus this code: struct foo_t foo; foo = bar; leaves the padding of foo intact, ie uninitialized random garbage. This patch fixes constant shader recompiles by initializing the struct to zero. For completeness, memcpy is used to copy the key to the shader struct. NOTE: This is a candidate for the stable branches.
