vulkan: Fix validation warnings on macOS #160

Closed kanerogers closed 6 months ago

kanerogers commented 6 months ago

Background

macOS devices running on MoltenVK have bizarrely low physical limits, especially for image samplers. We work around this by using descriptor indexing features, however, they must be configured correctly in order appease the validation layers:

VUID-VkPipelineLayoutCreateInfo-descriptorType-03016(ERROR / SPEC): msgNum: 1451322977 - Validation Error: [ VUID-VkPipelineLayoutCreateInfo-descriptorType-03016 ] | MessageID = 0x56816e61 | vkCreatePipelineLayout():  max per-stage sampler bindings count (1000) exceeds device maxPerStageDescriptorSamplers limit (16). The Vulkan spec states: The total number of descriptors in descriptor set layouts created without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set with a descriptorType of VK_DESCRIPTOR_TYPE_SAMPLER and VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER accessible to any given shader stage across all elements of pSetLayouts must be less than or equal to VkPhysicalDeviceLimits::maxPerStageDescriptorSamplers (https://vulkan.lunarg.com/doc/view/1.3.280.0/mac/1.3-extensions/vkspec.html#VUID-VkPipelineLayoutCreateInfo-descriptorType-03016)
