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
AttachmentStoreOp
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.
Note
The AttachmentStoreOp
ATTACHMENT_STORE_OP_STORE
may
force an implementation to assume that the attachment was written and
force an implementation to flush data to memory or to a higher level
cache. The AttachmentStoreOp
ATTACHMENT_STORE_OP_NONE_QCOM
may allow an implementation to assume that the attachment was not
written and allow an implementation to avoid such a flush..
