Description
Renderpass attachments can be read-only for the duration of a renderpass.
Examples include input attachments and depth attachments where depth tests are enabled but depth writes are not enabled.
In such cases, there can be no contents generated for an attachment within the render area.
This extension adds a new VkAttachmentStoreOp
VK_ATTACHMENT_STORE_OP_NONE_QCOM
which specifies that the contents
within the render area may not be written to memory, but that the prior
contents of the attachment in memory are preserved.
However, if any contents were generated within the render area during
rendering, the contents of the attachment will be undefined inside the
render area.
