212 * used in. The subpass dependency operates as if defined with the

215 * VkSubpassDependency implicitDependency = {
216 * .srcSubpass = VK_SUBPASS_EXTERNAL;
217 * .dstSubpass = firstSubpass; // First subpass attachment is used in
218 * .srcStageMask = VK_PIPELINE_STAGE_TOP_OF_PIPE_BIT;
219 * .dstStageMask = VK_PIPELINE_STAGE_ALL_COMMANDS_BIT;
220 * .srcAccessMask = 0;
221 * .dstAccessMask = VK_ACCESS_INPUT_ATTACHMENT_READ_BIT |
222 * VK_ACCESS_COLOR_ATTACHMENT_READ_BIT |
223 * VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT |
224 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT |
225 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
226 * .dependencyFlags = 0;
229 * Similarly, if there is no subpass dependency from the last subpass
230 * that uses an attachment to VK_SUBPASS_EXTERNAL, then an implicit
231 * subpass dependency exists from the last subpass it is used in to
232 * VK_SUBPASS_EXTERNAL. The subpass dependency operates as if defined
233 * with the following parameters:
235 * VkSubpassDependency implicitDependency = {
236 * .srcSubpass = lastSubpass; // Last subpass attachment is used in
237 * .dstSubpass = VK_SUBPASS_EXTERNAL;
238 * .srcStageMask = VK_PIPELINE_STAGE_ALL_COMMANDS_BIT;
239 * .dstStageMask = VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT;
240 * .srcAccessMask = VK_ACCESS_INPUT_ATTACHMENT_READ_BIT |
241 * VK_ACCESS_COLOR_ATTACHMENT_READ_BIT |
242 * VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT |
243 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT |
244 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
245 * .dstAccessMask = 0;
246 * .dependencyFlags = 0;
249 * We could implement this by walking over all of the attachments and
250 * subpasses and checking to see if any of them don't have an external
251 * dependency. Or, we could just be lazy and add a couple extra flushes.
252 * We choose to be lazy.
