lavapipe: enable subgroup quad operations
!16301 (merged) enabled lowering subgroup quad operations to subgroup shuffle operations in lavapipe, and I'm not sure why, but spirv_options.caps.subgroup_quad
was already set to true in lvp_shader_compile_to_ir
. All that's left is to flip the bit in VkPhysicalDeviceSubgroupProperties.supportedOperations
and the tests in dEQP-VK.subgroups.quad.*
pass.
