3/8/2021 · srcSubpass is the subpass index of the first subpass in the dependency, or VK_ SUBPASS _EXTERNAL. dstSubpass is the subpass index of the second subpass in the dependency, or VK_ SUBPASS _EXTERNAL. srcStageMask is a bitmask of VkPipelineStageFlagBits specifying the source stage mask.
No definition for VK_ SUBPASS _EXTERNAL in Vulkan.hpp? Ask Question Asked 3 years, 6 months ago. Active 3 years, 6 months ago. Viewed 141 times 0. The Vulkan.hpp seems to have an equivalent for everything in the C header file except for this. Am I missing something? Are there other discrepancies?, 10/11/2017 · The function SubpassDependency& setSrcSubpass( uint32_t srcSubpass_ ) can receive VK_ SUBPASS _EXTERNAL but this is not defined in vulkan.hpp: https://www.khronos.org/registry/vulkan/specs/1….
srcSubpass – Index of a first (previous) subpass or VK_ SUBPASS _EXTERNAL if we want to indicate dependency between subpass and operations outside of a render pass. dstSubpass – Index of a second (later) subpass (or VK_ SUBPASS _EXTERNAL). srcStageMask – Pipeline stage during which a given attachment was used before (in a src subpass).
If there is no subpass dependency from VK_ SUBPASS _EXTERNAL to the first subpass that uses an attachment, then an implicit subpass dependency exists from VK_ SUBPASS _EXTERNAL to the first subpass it is used in. The subpass dependency operates as if defined with the following parameters:, 3/8/2021 · For any element of pDependencies, if the dstSubpass is not VK_ SUBPASS _EXTERNAL, all stage flags included in the dstStageMask member of that dependency must be a pipeline stage supported by the pipeline identified by the pipelineBindPoint member of the destination subpass.
