[PATCH v2 0/4] MR394: vkd3d-shader: sm1 texture interface.
This defines (and, broadly, implements) the API for mapping sm1 combined samplers to the target environment. This is possibly the simplest bit of API for sm1 support thus far. It does not actually involve any API changes. Rather, each combined sampler is split into two descriptors, one for the sampler and one for the texture, both with the same binding index as the original combined sampler. -- I feel rather positive about this bit of API. it required very little design concern or implementation difficulty on the vkd3d side. On the Wine side, it required quite a lot of change, but I think pretty much all of that change was positive on its own merits, and should probably be applied independently of the sm1/Vulkan work. We've talked about translating wined3d_device_set_sampler_state() and wined3d_device_set_texture() to wined3d_device_set_sampler() and wined3d_device_set_shader_resource_view() for quite some time now, and that was pretty much exactly what was required to make this work—that and choosing the obvious mapping of "same index for both state objects". The most obvious alternative to this design, to me, would be to reroll struct vkd3d_shader_interface_info (or extend it without rerolling), adding a new array for mapping a combined sampler in the *source* environment to two separate descriptors in the *target* environment, i.e. struct vkd3d_shader_resource_binding in reverse. We would probably also want to design a way to map a combined sampler to a combined sampler (a sixth array? Or reuse struct vkd3d_shader_descriptor_binding with a new descriptor type?) I suppose the advantage of such an alternative design would be that it reports "one" descriptor as "one", not "two", but the associated complexity seems far greater, and accordingly I don't really want to give it the time of day. (Note also that this patch set handles combined -> combined mapping without any extra effort). I will of course yield to maintainer preference, though. -- As before, I've prepared proof-of-concept code for Wine. The branches are here: https://gitlab.winehq.org/zfigura/vkd3d/-/commits/himavant5 https://gitlab.winehq.org/zfigura/wine/-/commits/himavant6 The relevant test can be run with: make tests/shader_runner.exe && WINE_D3D_CONFIG=renderer=vulkan wine tests/shader_runner.exe ../vkd3d/tests/hlsl/tex2D.shader_test These branches are rather larger than the previous ones. By way of summary, the vkd3d branch contains these patches, plus about two dozen patches to hook up sm1 tests and to fix various corner cases surrounding semantic translation (much of which should be rewritten with a VSIR-based "lowering" approach in mind). The Wine branch contains: * Wine merge request 4027, * the patches for sm1 constant buffers, * a set of patches to transform individual sampler states into sampler objects (of which [1] is the most interesting), and * a set of patches to transform textures into SRVs (of which [2] is the most interesting). As described above, there is not actually any part of the Wine side that touches the vkd3d-shader interface. [1] https://gitlab.winehq.org/zfigura/wine/-/commit/984e478763c99157a6ec49388fe5... [2] https://gitlab.winehq.org/zfigura/wine/-/commit/722c1bf1f6a7691c9ed431bd4333... ``` What are the roots that clutch, what branches grow Out of this stony rubbish? Son of man, You cannot say, or guess, for you know only A heap of broken images, where the sun beats, And the dead tree gives no shelter, the cricket no relief, And the dry stone no sound of water. ``` -- v2: vkd3d-shader/ir: Translate TEX instructions to SAMPLE. vkd3d-shader: Scan combined sampler declarations. include: Define an API for mapping sm1 samplers to the target environment. https://gitlab.winehq.org/wine/vkd3d/-/merge_requests/394
