public final class EXTSubpassMergeFeedback
extends Object

This extension adds a mechanism to provide feedback to an application about whether the subpasses specified on render pass creation are merged by the implementation. Additionally, it provides a control to enable or disable subpass merging in the render pass.

Description

• SUBPASS_MERGE_STATUS_MERGED_EXT specifies the subpass is merged with a previous subpass.
• SUBPASS_MERGE_STATUS_DISALLOWED_EXT specifies the subpass is disallowed to merge with previous subpass. If the render pass does not allow subpass merging, then all subpass statuses are set to this value. If a subpass description does not allow subpass merging, then only that subpass’s status is set to this value.
• SUBPASS_MERGE_STATUS_NOT_MERGED_SIDE_EFFECTS_EXT specifies the subpass is not merged because it contains side effects.
• SUBPASS_MERGE_STATUS_NOT_MERGED_SAMPLES_MISMATCH_EXT specifies the subpass is not merged because sample count is not compatible with previous subpass.
• SUBPASS_MERGE_STATUS_NOT_MERGED_VIEWS_MISMATCH_EXT specifies the subpass is not merged because view masks do not match with previous subpass.
• SUBPASS_MERGE_STATUS_NOT_MERGED_ALIASING_EXT specifies the subpass is not merged because of attachments aliasing between them.
• SUBPASS_MERGE_STATUS_NOT_MERGED_DEPENDENCIES_EXT specifies the subpass is not merged because subpass dependencies do not allow merging.
• SUBPASS_MERGE_STATUS_NOT_MERGED_INCOMPATIBLE_INPUT_ATTACHMENT_EXT specifies the subpass is not merged because input attachment is not a color attachment from previous subpass or the formats are incompatible.
• SUBPASS_MERGE_STATUS_NOT_MERGED_TOO_MANY_ATTACHMENTS_EXT specifies the subpass is not merged because of too many attachments.
• SUBPASS_MERGE_STATUS_NOT_MERGED_INSUFFICIENT_STORAGE_EXT specifies the subpass is not merged because of insufficient memory.
• SUBPASS_MERGE_STATUS_NOT_MERGED_DEPTH_STENCIL_COUNT_EXT specifies the subpass is not merged because of too many depth/stencil attachments.
• SUBPASS_MERGE_STATUS_NOT_MERGED_RESOLVE_ATTACHMENT_REUSE_EXT specifies the subpass is not merged because a resolve attachment is reused as an input attachment in a subsequent subpass.
• SUBPASS_MERGE_STATUS_NOT_MERGED_SINGLE_SUBPASS_EXT specifies the subpass is not merged because the render pass has only one subpass.
• SUBPASS_MERGE_STATUS_NOT_MERGED_UNSPECIFIED_EXT specifies other reasons why subpass is not merged. It is also the recommended default value that should be reported when a subpass is not merged and when no other value is appropriate.
