The free OSR Learning Library has more than 50 articles on a wide variety of topics about writing and debugging device drivers and Minifilters. From introductory level to advanced. All the articles have been recently reviewed and updated, and are written using the clear and definitive style you've come to expect from OSR over the years.

I have below inherited code that creates syncScope/AutoSerialization (w.r.t workItem).
I have below questions as to what Fx does with below settings
1. Is the WorkItem serialized against anything in driver (those callbacks which have AutomaticSerialization = TRUE (and ExecutionLevelPassive)); ? Not sure
2. Is the workItem serialized against itself ? YES?
//queue WDF_IO_QUEUE_CONFIG_INIT(&queueConfig, WdfIoQueueDispatchManual); queueConfig.PowerManaged = WdfFalse; WDF_OBJECT_ATTRIBUTES attributes; attributes.ParentObject = Device; attributes.ExecutionLevel = WdfExecutionLevelPassive; attributes.SynchronizationScope = WdfSynchronizationScopeQueue; WDFQUEUE ParentObjectWdfQueue = NULL; NTSTATUS status = WdfIoQueueCreate(Device, &queueConfig, &attributes, &ParentObjectWdfQueue); --Workitem WDF_WORKITEM_CONFIG_INIT(&workitemConfig, func); NT_ASSERT(workitemConfig.AutomaticSerialization == TRUE); // Set the parent object to be device WDF_OBJECT_ATTRIBUTES_INIT_CONTEXT_TYPE(&attributes, WORKITEM_CONTEXT); attributes.ParentObject = ParentObjectWdfQueue; //parent is queue, parent of queue is device NTSTATUS status = WdfWorkItemCreate(&workitemConfig, &attributes, t);
