Description
General hints about the type of memory that should be allocated by Sysmem based on the expected usage of the images in the buffer collection include:
-
VK_IMAGE_CONSTRAINTS_INFO_CPU_READ_RARELY_FUCHSIA -
VK_IMAGE_CONSTRAINTS_INFO_CPU_READ_OFTEN_FUCHSIA -
VK_IMAGE_CONSTRAINTS_INFO_CPU_WRITE_RARELY_FUCHSIA -
VK_IMAGE_CONSTRAINTS_INFO_CPU_WRITE_OFTEN_FUCHSIA
For protected memory:
-
VK_IMAGE_CONSTRAINTS_INFO_PROTECTED_OPTIONAL_FUCHSIAspecifies that protected memory is optional for the buffer collection.
Note that if all participants in the buffer collection (Vulkan or otherwise) specify that protected memory is optional, Sysmem will not allocate protected memory.
