Structure specifying a subpass description.
Description

Each element of the pInputAttachments array corresponds to an input attachment index in a fragment shader, i.e. if a shader declares an image variable decorated with a InputAttachmentIndex value of X, then it uses the attachment provided in pInputAttachments[X]. Input attachments must also be bound to the pipeline in a descriptor set. If the attachment member of any element of pInputAttachments is ATTACHMENT_UNUSED, the application must not read from the corresponding input attachment index. Fragment shaders can use subpass input variables to access the contents of an input attachment at the fragment's (x, y, layer) framebuffer coordinates.

Each element of the pColorAttachments array corresponds to an output location in the shader, i.e. if the shader declares an output variable decorated with a Location value of X, then it uses the attachment provided in pColorAttachments[X]. If the attachment member of any element of pColorAttachments is ATTACHMENT_UNUSED, writes to the corresponding location by a fragment are discarded.

If pResolveAttachments is not NULL, each of its elements corresponds to a color attachment (the element in pColorAttachments at the same index), and a multisample resolve operation is defined for each attachment. At the end of each subpass, multisample resolve operations read the subpass's color attachments, and resolve the samples for each pixel to the same pixel location in the corresponding resolve attachments, unless the resolve attachment index is ATTACHMENT_UNUSED.

Similarly, if VkSubpassDescriptionDepthStencilResolveKHR::pDepthStencilResolveAttachment is not NULL and does not have the value ATTACHMENT_UNUSED, it corresponds to the depth/stencil attachment in pDepthStencilAttachment, and multisample resolve operations for depth and stencil are defined by VkSubpassDescriptionDepthStencilResolveKHR::depthResolveMode and VkSubpassDescriptionDepthStencilResolveKHR::stencilResolveMode, respectively. At the end of each subpass, multisample resolve operations read the subpass's depth/stencil attachment, and resolve the samples for each pixel to the same pixel location in the corresponding resolve attachment. If VkSubpassDescriptionDepthStencilResolveKHR::depthResolveMode is RESOLVE_MODE_NONE_KHR, then the depth component of the resolve attachment is not written to and its contents are preserved. Similarly, if VkSubpassDescriptionDepthStencilResolveKHR::stencilResolveMode is RESOLVE_MODE_NONE_KHR, then the stencil component of the resolve attachment is not written to and its contents are preserved. VkSubpassDescriptionDepthStencilResolveKHR::depthResolveMode is ignored if the VkFormat of the pDepthStencilResolveAttachment does not have a depth component. Similarly, VkSubpassDescriptionDepthStencilResolveKHR::stencilResolveMode is ignored if the VkFormat of the pDepthStencilResolveAttachment does not have a stencil component.

If the image subresource range referenced by the depth/stencil attachment is created with IMAGE_CREATE_SAMPLE_LOCATIONS_COMPATIBLE_DEPTH_BIT_EXT, then the multisample resolve operation uses the sample locations state specified in the sampleLocationsInfo member of the element of the VkRenderPassSampleLocationsBeginInfoEXT::pPostSubpassSampleLocations for the subpass.

If pDepthStencilAttachment is NULL, or if its attachment index is ATTACHMENT_UNUSED, it indicates that no depth/stencil attachment will be used in the subpass.

The contents of an attachment within the render area become undefined at the start of a subpass S if all of the following conditions are true:
- The attachment is used as a color, depth/stencil, or resolve attachment in any subpass in the render pass.
- There is a subpass S₁ that uses or preserves the attachment, and a subpass dependency from S₁ to S.
- The attachment is not used or preserved in subpass S.
Once the contents of an attachment become undefined in subpass S, they remain undefined for subpasses in subpass dependency chains starting with subpass S until they are written again. However, they remain valid for subpasses in other subpass dependency chains starting with subpass S₁ if those subpasses use or preserve the attachment.

Valid Usage
- pipelineBindPoint must be PIPELINE_BIND_POINT_GRAPHICS
- colorAttachmentCount must be less than or equal to VkPhysicalDeviceLimits::maxColorAttachments
- If the first use of an attachment in this render pass is as an input attachment, and the attachment is not also used as a color or depth/stencil attachment in the same subpass, then loadOp must not be ATTACHMENT_LOAD_OP_CLEAR
- If pResolveAttachments is not NULL, for each resolve attachment that is not ATTACHMENT_UNUSED, the corresponding color attachment must not be ATTACHMENT_UNUSED
- If pResolveAttachments is not NULL, for each resolve attachment that is not ATTACHMENT_UNUSED, the corresponding color attachment must not have a sample count of SAMPLE_COUNT_1_BIT
- If pResolveAttachments is not NULL, each resolve attachment that is not ATTACHMENT_UNUSED must have a sample count of SAMPLE_COUNT_1_BIT
- If pResolveAttachments is not NULL, each resolve attachment that is not ATTACHMENT_UNUSED must have the same VkFormat as its corresponding color attachment
- All attachments in pColorAttachments that are not ATTACHMENT_UNUSED must have the same sample count
- All attachments in pInputAttachments that are not ATTACHMENT_UNUSED must have formats whose features contain at least one of FORMAT_FEATURE_COLOR_ATTACHMENT_BIT or FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT.
- All attachments in pColorAttachments that are not ATTACHMENT_UNUSED must have formats whose features contain FORMAT_FEATURE_COLOR_ATTACHMENT_BIT
- All attachments in pResolveAttachments that are not ATTACHMENT_UNUSED must have formats whose features contain FORMAT_FEATURE_COLOR_ATTACHMENT_BIT
- If pDepthStencilAttachment is not NULL and the attachment is not ATTACHMENT_UNUSED then it must have a format whose features contain FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT
- If the VK_AMD_mixed_attachment_samples extension is enabled, and all attachments in pColorAttachments that are not ATTACHMENT_UNUSED must have a sample count that is smaller than or equal to the sample count of pDepthStencilAttachment if it is not ATTACHMENT_UNUSED
- If neither the VK_AMD_mixed_attachment_samples nor the VK_NV_framebuffer_mixed_samples extensions are enabled, and if pDepthStencilAttachment is not ATTACHMENT_UNUSED and any attachments in pColorAttachments are not ATTACHMENT_UNUSED, they must have the same sample count
- The attachment member of each element of pPreserveAttachments must not be ATTACHMENT_UNUSED
- Each element of pPreserveAttachments must not also be an element of any other member of the subpass description
- If any attachment is used by more than one VkAttachmentReference member, then each use must use the same layout
- If flags includes SUBPASS_DESCRIPTION_PER_VIEW_POSITION_X_ONLY_BIT_NVX, it must also include SUBPASS_DESCRIPTION_PER_VIEW_ATTRIBUTES_BIT_NVX.
Valid Usage (Implicit)
- flags must be a valid combination of VkSubpassDescriptionFlagBits values
- pipelineBindPoint must be a valid VkPipelineBindPoint value
- If inputAttachmentCount is not 0, pInputAttachments must be a valid pointer to an array of inputAttachmentCount valid VkAttachmentReference structures
- If colorAttachmentCount is not 0, pColorAttachments must be a valid pointer to an array of colorAttachmentCount valid VkAttachmentReference structures
- If colorAttachmentCount is not 0, and pResolveAttachments is not NULL, pResolveAttachments must be a valid pointer to an array of colorAttachmentCount valid VkAttachmentReference structures
- If pDepthStencilAttachment is not NULL, pDepthStencilAttachment must be a valid pointer to a valid VkAttachmentReference structure
- If preserveAttachmentCount is not 0, pPreserveAttachments must be a valid pointer to an array of preserveAttachmentCount uint32_t values
