* mesa,i965: use NewDriverState to communicate TFB state changes with the driverMarek Olšák2013-04-248-22/+42
| | | | | | | | | | | | | | | | | | | | | | | _NEW_TRANSFORM_FEEDBACK is not used by core Mesa, so it can be removed. Instead, an new private flag is added to i965 to serve the same purpose. If you're new to this: * When creating a context. you can set private dirty flags in gl_context::DriverFlags, eg.: ctx->DriverFlags.NewStateX = BRW_NEW_STATE_X; * When StateX is changed, core Mesa does: ctx->NewDriverState |= ctx->DriverFlags.NewStateX; * When you have to draw, read and clear ctx->NewDriverState. * Pros: not touching NewState, the driver decides the mapping between GL states and hw state groups, unlimited number of flags in core Mesa (still limited number of flags in the driver though) Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Eric Anholt <[email protected]>

* r600g: initialize CMASK and HTILE with the GPU using streamoutMarek Olšák2013-04-234-7/+80
| | | | | | | | | | | | | This fixes a crash when a resource cannot be mapped to the CPU's address space because it's too big. This puts a global pipe_context in r600_screen, which is guarded by a mutex, so that we can use pipe_context when there isn't one around. Hopefully our multi-context support is solid.

* gallivm: implement switch opcodeRoland Scheidegger2013-04-203-12/+340
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Should be able to handle all things which make this tricky to implement. Fallthroughs, including most notably into/out of default, should be handled correctly but are quite a mess. If we see largely unoptimized switches in the wild should probably think about some "real" switch optimization pass, e.g. things like this: switch case1 someinst brk case2 default case3 someinst brk case4 someinst endswitch are legal, but the pointless case2/case3 statements not only cause condition evaluation but will turn this into a "fake" fallthrough case (because mask and defaultmask are already updated for case2 when default is encountered) requiring executing code twice. If default is at the end though, there's never any code re-execution, and if that's not the case if there's no fallthrough in (not even a fake one) and out of default there's no code re-execution neither. v2: add comments, and use enum for break type instead of magic boolean.

* gallivm: increase nesting limit to 66Roland Scheidegger2013-04-201-2/+4
| | | | | | | | | | | This is still not really correct, since at least for sm 4.0 the nesting limit is 64 per subroutine, and subroutine nesting itself has a limit of 32, so since we have a flat stack we'd need 32*64. But this should probably be better fixed with per-subroutine stacks, since otherwise these structures get really big (like 100kB for the lp_exec_mask). Reviewed-by: Jose Fonseca <[email protected]>
* draw: implement primitive assemblerZack Rusin2013-04-187-4/+386
| | | | | | | | | | | | | | | | | | | | Input assembler needs to be able to decompose adjacency primitives into something that can be understood by the rest of the pipeline. The specs say that the adjacency primitives are *only* visible in the geometry shader, for everything else they need to be decomposed. Which in most of the cases is not an issue, because the geometry shader always decomposes them for us, but without geometry shader we were passing unchanged adjacency primitives to the rest of the pipeline and causing crashes everywhere. This commit introduces a primitive assembler which, if geometry shader is missing and the input primitive is one of the adjacency primitives, decomposes them into something that the rest of the pipeline can understand.
