151 * dependency exists from VK_SUBPASS_EXTERNAL to the first subpass it is
152 * used in. The subpass dependency operates as if defined with the
153 * following parameters:
154 *
155 * VkSubpassDependency implicitDependency = {
156 * .srcSubpass = VK_SUBPASS_EXTERNAL;
157 * .dstSubpass = firstSubpass; // First subpass attachment is used in
158 * .srcStageMask = VK_PIPELINE_STAGE_TOP_OF_PIPE_BIT;
159 * .dstStageMask = VK_PIPELINE_STAGE_ALL_COMMANDS_BIT;
160 * .srcAccessMask = 0;
161 * .dstAccessMask = VK_ACCESS_INPUT_ATTACHMENT_READ_BIT |
162 * VK_ACCESS_COLOR_ATTACHMENT_READ_BIT |
163 * VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT |
164 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT |
165 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
166 * .dependencyFlags = 0;
167 * };
168 *
169 * Similarly, if there is no subpass dependency from the last subpass
170 * that uses an attachment to VK_SUBPASS_EXTERNAL, then an implicit
171 * subpass dependency exists from the last subpass it is used in to
172 * VK_SUBPASS_EXTERNAL. The subpass dependency operates as if defined
173 * with the following parameters:
174 *
175 * VkSubpassDependency implicitDependency = {
176 * .srcSubpass = lastSubpass; // Last subpass attachment is used in
177 * .dstSubpass = VK_SUBPASS_EXTERNAL;
178 * .srcStageMask = VK_PIPELINE_STAGE_ALL_COMMANDS_BIT;
179 * .dstStageMask = VK_PIPELINE_STAGE_BOTTOM_OF_PIPE_BIT;
180 * .srcAccessMask = VK_ACCESS_INPUT_ATTACHMENT_READ_BIT |
181 * VK_ACCESS_COLOR_ATTACHMENT_READ_BIT |
182 * VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT |
183 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_READ_BIT |
184 * VK_ACCESS_DEPTH_STENCIL_ATTACHMENT_WRITE_BIT;
185 * .dstAccessMask = 0;
186 * .dependencyFlags = 0;
187 * };
188 *
189 * We could implement this by walking over all of the attachments and
190 * subpasses and checking to see if any of them don't have an external
191 * dependency. Or, we could just be lazy and add a couple extra flushes.
192 * We choose to be lazy.
193 *
194 * From the documentation for vkCmdNextSubpass:
195 *
196 * "Moving to the next subpass automatically performs any multisample
197 * resolve operations in the subpass being ended. End-of-subpass
198 * multisample resolves are treated as color attachment writes for the
199 * purposes of synchronization. This applies to resolve operations for
200 * both color and depth/stencil attachments. That is, they are
201 * considered to execute in the
202 * VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT pipeline stage and
203 * their writes are synchronized with
204 * VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT."
205 *
206 * Therefore, the above flags concerning color attachments also apply to
207 * color and depth/stencil resolve attachments.
