* gallium: add a a new cap for changing the TGSI TG4 instruction encodingDave Airlie2019-10-112-0/+9
| | | | | | | | | | | | | Accessing the TG4 component via immediates in the llvmpipe backend is quite messy (like really messy). Roland suggested we change the instruction encoding, so introduce a cap to allow the component to be selected to be store in the sampler swizzle, which should be otherwise unused. I could probably switch all drivers over, but virgl would need some work that I'd prefer not to rush it.

| | | | | | | | | | | | To enable EXT_demote_to_helper_invocation: This extension adds a "demote" keyword that is similar to "discard" but only suppresses subsequent writes and outputs to the framebuffer, and does not terminate the execution of the invocation. For the remainder of the execution, the invocation is "demoted" to act like a helper invocation. Reviewed-by: Kenneth Graunke <[email protected]>

* gallium: Add ARB_gl_spirv supportCaio Marcelo de Oliveira Filho2019-09-101-0/+2
| | | | | | | | | | | | | | The PIPE_CAP_GL_SPIRV capability enables ARB_gl_spirv and ARB_spirv_extensions, and will make sure the corresponding SPIR-V capabilities and extensions lists are initialized. The additional PIPE_CAP_GL_SPIRV_VARIABLE_POINTERS capability enables the support for Variable Pointers in SPIR-V shaders. This depends on the driver and is not mandatory for ARB_gl_spirv support. v2: Add a PIPE_CAP for Variable Pointers. (Marek) Reviewed-by: Alejandro Piñeiro <[email protected]> [v1]

| | | | | | | | | | For radeonsi, we will prefer the NIR pass as it'll generate better code (some index calculation and a single load vs. a load, then index calculation, then another load) and oftentimes NIR optimization can kick in and make all the access indices constant.

* gallium/vl: use compute preference for all multimedia, not just blitIlia Mirkin2019-08-201-2/+2
| | | | | | | | | | | | The compute paths in vl are a bit AMD-specific. For example, they (on nouveau), try to use a BGRX8 image format, which is not supported. Fixing all this is probably possible, but since the compute paths aren't in any way better, it's difficult to care.

* gallium: get rid of PIPE_CAP_SM3Erik Faye-Lund2019-07-101-2/+0
| | | | | | | | | | | | | | | | | | | | | PIPE_CAP_SM3 has always been an odd one out of all our caps. While most other caps are fine-grained and single-purpose, this cap encode several features in one. And since OpenGL cares more about single features, it'd be nice to get rid of this one. As it turns, this is now relatively simple. We only really care about three features using this cap, and those already got their own caps. So we can remove it, and make sure all current drivers just give the same response to all of them. The only place we *really* care about SM3 is in nine, and there we can instead just re-construct the information based on the finer-grained caps. This avoids DX9 semantics from needlessly leaking into all of the drivers, most of who doesn't care a whole lot about DX9 specifically.

To express this, this patch renames PIPE_CAP_TGSI_FS_FBFETCH to simply PIPE_CAP_FBFETCH, and converts it from a boolean "is FBFETCH supported?" to an integer number of render targets which can be fetched.
