* 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:
|
|
*
|
|
* VkSubpassDependency implicitDependency = {
|
|
* .srcSubpass = VK_SUBPASS_EXTERNAL;
|
|
* .dstSubpass = firstSubpass; // First subpass attachment is used in

* .srcStageMask = VK_PIPELINE_STAGE_TOP_OF_PIPE_BIT;

|
|
* VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
|
|
* .dependencyFlags = 0;
|
|
* };
|
|
*
|
|
* Similarly, if there is no subpass dependency from the last subpass
|
|
* that uses an attachment to VK_SUBPASS_EXTERNAL, then an implicit
|
|
* subpass dependency exists from the last subpass it is used in to
|
|
* VK_SUBPASS_EXTERNAL. The subpass dependency operates as if defined
|
|
* with the following parameters:
|
|
*
|
|
* VkSubpassDependency implicitDependency = {
|
|
* .srcSubpass = lastSubpass; // Last subpass attachment is used in
|
|
* .dstSubpass = VK_SUBPASS_EXTERNAL;
|
|
* .srcStageMask = VK_PIPELINE_STAGE_ALL_COMMANDS_BIT;
|
|
* .dstStageMask = VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT;
|
|
* .srcAccessMask = VK_ACCESS_INPUT_ATTACHMENT_READ_BIT |
|
|
* VK_ACCESS_COLOR_ATTACHMENT_READ_BIT |
|
|
* VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT |
|
|
* VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT |
|
|
* VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
|
|
* .dstAccessMask = 0;
|
|
* .dependencyFlags = 0;
|
|
* };
|
|
*
|
|
* We could implement this by walking over all of the attachments and
|
|
* subpasses and checking to see if any of them don't have an external
|
|
* dependency. Or, we could just be lazy and add a couple extra flushes.
|
|
* We choose to be lazy.
|
|
*
|
|
* From the documentation for vkCmdNextSubpass:
|
|
*
|
|
* "Moving to the next subpass automatically performs any multisample
|
|
* resolve operations in the subpass being ended. End-of-subpass
|
|
* multisample resolves are treated as color attachment writes for the
|
|
* purposes of synchronization. This applies to resolve operations for
|
|
* both color and depth/stencil attachments. That is, they are
|
|
* considered to execute in the
|
|
* VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT pipeline stage and
|
|
* their writes are synchronized with
|
|
* VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT."
|
|
*
|
|
* Therefore, the above flags concerning color attachments also apply to
|
|
* color and depth/stencil resolve attachments.
