225 * .dstSubpass = firstSubpass; // First subpass attachment is used in
226 * .srcStageMask = VK_PIPELINE_STAGE_TOP_OF_PIPE_BIT;

232 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT |
233 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
234 * .dependencyFlags = 0;
237 * Similarly, if there is no subpass dependency from the last subpass
238 * that uses an attachment to VK_SUBPASS_EXTERNAL, then an implicit
239 * subpass dependency exists from the last subpass it is used in to
240 * VK_SUBPASS_EXTERNAL. The subpass dependency operates as if defined
241 * with the following parameters:
243 * VkSubpassDependency implicitDependency = {
244 * .srcSubpass = lastSubpass; // Last subpass attachment is used in
245 * .dstSubpass = VK_SUBPASS_EXTERNAL;
246 * .srcStageMask = VK_PIPELINE_STAGE_ALL_COMMANDS_BIT;
247 * .dstStageMask = VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT;
248 * .srcAccessMask = VK_ACCESS_INPUT_ATTACHMENT_READ_BIT |
249 * VK_ACCESS_COLOR_ATTACHMENT_READ_BIT |
250 * VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT |
251 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT |
252 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
253 * .dstAccessMask = 0;
254 * .dependencyFlags = 0;
257 * We could implement this by walking over all of the attachments and
258 * subpasses and checking to see if any of them don't have an external
259 * dependency. Or, we could just be lazy and add a couple extra flushes.
260 * We choose to be lazy.
