The spec doesn't mention any limits on * nestedness of label regions. This implementation assumes that there * aren't any. * * The spec, however, doesn't explain the lifetime of a label submitted by * an `*InsertDebugUtilsLabel` call. The LunarG whitepaper [1] (pp 12-15) * provides a more detailed explanation along with some examples. According * to those, such label remains active until the next `*DebugUtilsLabel` * call. This means that there can be no more than one such label at a * time. * * ``labels`` contains all active labels at this point in order of * submission ``region_begin`` denotes whether the most recent label opens * a new region If ``labels`` is empty ``region_begin`` must be true. * * Anytime we modify labels, we first check for ``region_begin``. If it's * false, it means that the most recent label was submitted by * `*InsertDebugUtilsLabel` and we need to remove it before doing anything * else. * * See the discussion here: * https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/10318#note_1061317 * * [1] https://www.lunarg.com/wp-content/uploads/2018/05/Vulkan-Debug-Utils_05_18_v1.pdf */ struct util_dynarray labels; bool region_begin; struct vk_render_pass *render_pass; uint32_t subpass_idx; struct vk_framebuffer *framebuffer; VkRect2D render_area; /** * True if we are currently inside a CmdPipelineBarrier() is inserted by * the runtime's vk_render_pass.c */ bool runtime_rp_barrier; /* This uses the same trick as STACK_ARRAY */ struct vk_attachment_state *attachments; struct vk_attachment_state _attachments[8]; VkRenderPassSampleLocationsBeginInfoEXT *pass_sample_locations; /** * Bitmask of shader stages bound via a vk_pipeline since the last call to * vkBindShadersEXT(). * * Used by the common vk_pipeline implementation */ VkShaderStageFlags pipeline_shader_stages; }; VK_DEFINE_HANDLE_CASTS(vk_command_buffer, base, VkCommandBuffer, VK_OBJECT_TYPE_COMMAND_BUFFER) VkResult MUST_CHECK vk_command_buffer_init(struct vk_command_pool *pool, struct vk_command_buffer *command_buffer, const struct vk_command_buffer_ops *ops, VkCommandBufferLevel level); void vk_command_buffer_reset_render_pass(struct vk_command_buffer *cmd_buffer); void vk_command_buffer_reset(struct vk_command_buffer *command_buffer); void vk_command_buffer_recycle(struct vk_command_buffer *command_buffer); void vk_command_buffer_begin(struct vk_command_buffer *command_buffer, const VkCommandBufferBeginInfo *pBeginInfo); VkResult vk_command_buffer_end(struct vk_command_buffer *command_buffer); void vk_command_buffer_finish(struct vk_command_buffer *command_buffer); static inline VkResult __vk_command_buffer_set_error(struct vk_command_buffer *command_buffer, VkResult error, const char *file, int line) { assert(error != VK_SUCCESS); error = __vk_errorf(command_buffer, error, file, line, NULL); if (command_buffer->record_result == VK_SUCCESS) command_buffer->record_result = error; return error; } #define vk_command_buffer_set_error(command_buffer, error) \ __vk_command_buffer_set_error(command_buffer, error, __FILE__, __LINE__) static inline VkResult vk_command_buffer_get_record_result(struct vk_command_buffer *command_buffer) { return command_buffer->record_result; } #define vk_command_buffer_has_error(command_buffer) \ unlikely((command_buffer)->record_result != VK_SUCCESS) #ifdef __cplusplus } #endif #endif /* VK_COMMAND_BUFFER_H */
