* ac/nir: Only clamp shadow reference on radeonsi.Bas Nieuwenhuizen2017-10-231-0/+1
| | | | | | | | | | | | | | | | | | Vulkan CTS does not expect the value to be clamped (at least for D32), and it makes a differences even though depth is in [0,1], due to strict inequalities. I couldn't find anything in the Vulkan spec about this, but the test seemed to be copied from GL tests and the GL spec only specifies clamping for fixed point formats. Hence I expect radeonsi to run into this at some point as well, but given that they still have a usecase with the Z16->Z32 promotion, I'll leave that for someone else to clean up. This at least fixes radv dEQP-VK.texture.shadow.* on VI. Fixes: 0f9e32519bb 'ac/nir: clamp shadow texture comparison value on VI' Reviewed-by: Dave Airlie <[email protected]>

* ac/nir: Add shader support for multiviews.Bas Nieuwenhuizen2017-08-241-1/+3
| | | | | | | | | It uses an user SGPR to pass the view index to the shaders, except for the fragment shader where we use layer=view (which comes in handy when we want to do the NV ext that allows us to execute pre-FS stages once instead of per view). Reviewed-by: Dave Airlie <[email protected]>

* ac/nir: begin splitting off ac_nir_contextNicolai Hähnle2017-07-311-0/+6
| | | | | | | | | | | | | The eventual goal is to hide all radv-specific details behind ac_nir_context::abi, so that the NIR->LLVM code can be re-used by radeonsi. During development, we live with a partial split, where some of the NIR->LLVM code still relies on linking back to the nir_to_llvm_context (which should ultimately be renamed to reflect that it's radv-specific). The idea is to get rid of these backlinks over time. Reviewed-by: Marek Olšák <[email protected]>

* radv/ac: add support for indirect access of descriptor sets.Dave Airlie2017-04-191-2/+3
| | | | | | | | | | | | | | | | | | | We want to expose more descriptor sets to the applications, but currently we have a 1:1 mapping between shader descriptor sets and 2 user sgprs, limiting us to 4 per stage. This commit check if we don't have enough user sgprs for the number of bound sets for this shader, we can ask for them to be indirected. Two sgprs are then used to point to a buffer or 64-bit pointers to the number of allocated descriptor sets. All shaders point to the same buffer. We can use some user sgprs to inline one or two descriptor sets in future, but until we have a workload that needs this I don't think we should spend too much time on it.

* radv/ac: add initial pre-pass for shader info gatheringDave Airlie2017-04-191-2/+2
| | | | | | | | | | | | There is some radv specific info we need to gather from shaders before we get into converting nir->llvm, so we can make better decisions especially around user sgpr allocation.

* radv: overhaul fragment shader sample positions.Dave Airlie2017-04-041-1/+3
| | | | | | | | | | | | | | | | | | The current code was broken, and I decided to redesign it instead. This puts the sample positions for all samples into the queue constant descriptor buffer after all the spill/ring descriptors. It then uses a single offset register to point how far into the samples the samples for num_samples are. This saves one user sgpr and means we only generate the sample position data in the rare single case where we need it currently. This doesn't fix the failing CTS tests without the followup fix.
