* radv: Increase the number of dynamic uniform buffers.Bas Nieuwenhuizen2018-03-122-3/+5
| | | | | | | | | | | | | The vulkan API is not ideal as it does not allow us have a shared limit. Feral needs 15+6 for one of their games, and I'm not a fan of overcommitting the limits, so increase the number of dynamic uniform buffers to 16.

* r600: implement callstack workaround for evergreen.Dave Airlie2018-03-121-8/+31
| | | | | | | | | | | | | | | | | | | | This is ported from the sb backend, there are some issues with evergreen stacks on the boundary between entries and ALU_PUSH_BEFORE instructions. Whenever we are going to use a push before, we check the stack usage and if we have to use the workaround, then we switch to a separate push. I noticed this problem dealing with some of the soft fp64 shaders, in nosb mode, they are quite stack happy. This fixes all the glitches and inconsistencies I've seen with them Reviewed-by: Roland Scheidegger <[email protected]> Tested-by: Elie Tournier <[email protected]> Cc: <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tegra K1 and later use a GPU that can be driven by the Nouveau driver. But the GPU is a pure render node and has no display engine, hence the scanout needs to happen on the Tegra display hardware. The GPU and the display engine each have a separate DRM device node exposed by the kernel. To make the setup appear as a single device, this driver instantiates a Nouveau screen with each instance of a Tegra screen and forwards GPU requests to the Nouveau screen. For purposes of scanout it will import buffers created on the GPU into the display driver. Handles that userspace requests are those of the display driver so that they can be used to create framebuffers. This has been tested with some GBM test programs, as well as kmscube and weston. All of those run without modifications, but I'm sure there is a lot that can be improved. Some fixes contributed by Hector Martin <[email protected]>. Changes in v2: - duplicate file descriptor in winsys to avoid potential issues - require nouveau when building the tegra driver - check for nouveau driver name on render node - remove unneeded dependency on libdrm_tegra - remove zombie references to libudev - add missing headers to C_SOURCES variable - drop unneeded tegra/ prefix for includes - open device files with O_CLOEXEC - update copyrights Changes in v3: - properly unwrap resources in ->resource_copy_region() - support vertex buffers passed by user pointer - allocate custom stream and const uploader - silence error message on pre-Tegra124 - support X without explicit PRIME Changes in v4: - ship Meson build files in distribution tarball - drop duplicate driver_tegra dependency Reviewed-by: Emil Velikov <[email protected]> Acked-by: Emil Velikov <[email protected]> Tested-by: Andre Heider <[email protected]> Reviewed-by: Dmitry Osipenko <[email protected]> Reviewed-by: Dylan Baker <[email protected]> Signed-off-by: Thierry Reding <[email protected]>

* i965/vec4: Relax writemask condition in CSEIan Romanick2018-03-081-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the previously seen instruction generates more fields than the new instruction, still allow CSE to happen. This doesn't do much, but it also enables a couple more shaders in the next patch. It helped quite a bit in another change series that I have (at least for now) abandoned. v2: Add some extra comentary about the parameters to instructions_match. Suggested by Ken. No changes on Skylake, Broadwell, Iron Lake or GM45. Ivy Bridge and Haswell had similar results.
