org.lwjgl.vulkan.EXTSubpassMergeFeedback

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.

• SUBPASS_MERGE_STATUS_NOT_MERGED_SIDE_EFFECTS_EXT specifies that the subpass is not merged because it contains side effects.
• SUBPASS_MERGE_STATUS_NOT_MERGED_SAMPLES_MISMATCH_EXT specifies that the subpass is not merged because sample count is not compatible with the previous subpass.

• SUBPASS_MERGE_STATUS_NOT_MERGED_TOO_MANY_ATTACHMENTS_EXT specifies that the subpass is not merged because of too many attachments.
• SUBPASS_MERGE_STATUS_NOT_MERGED_INSUFFICIENT_STORAGE_EXT specifies that the subpass is not merged because of insufficient memory.
• SUBPASS_MERGE_STATUS_NOT_MERGED_DEPTH_STENCIL_COUNT_EXT specifies that the subpass is not merged because of too many depth/stencil attachments.
• SUBPASS_MERGE_STATUS_NOT_MERGED_RESOLVE_ATTACHMENT_REUSE_EXT specifies that 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 that the subpass is not merged because the render pass has only one subpass.
• SUBPASS_MERGE_STATUS_NOT_MERGED_UNSPECIFIED_EXT specifies that the subpass is not merged for unspecified reasons. Implementations should return this value when no other VkSubpassMergeStatusEXT value is appropriate.
