This adds debugfs consumer for xHCI driver. The debugfs entries read all host registers, device/endpoint contexts, command ring, event ring and various endpoint rings. With these entries, users can check the registers and memory spaces used by a host during run time, or save all the information with a simple 'cp -r' for post-mortem programs. The file hierarchy looks like this. [root of debugfs] |__usb |____[e,u,o]hci <---------[root for other HCIs] |____xhci <---------------[root for xHCI] |______0000:00:14.0 <--------------[xHCI host name] |________reg-cap <--------[capability registers] |________reg-op <-------[operational registers] |________reg-runtime <-----------[runtime registers] |________reg-ext-#cap_name <----[extended capability regs] |________command-ring <-------[root for command ring] |__________cycle <------------------[ring cycle] |__________dequeue <--------[ring dequeue pointer] |__________enqueue <--------[ring enqueue pointer] |__________trbs <-------------------[ring trbs] |________event-ring <---------[root for event ring] |__________cycle <------------------[ring cycle] |__________dequeue <--------[ring dequeue pointer] |__________enqueue <--------[ring enqueue pointer] |__________trbs <-------------------[ring trbs] |________devices <------------[root for devices] |__________#slot_id <-----------[root for a device] |____________name <-----------------[device name] |____________slot-context <----------------[slot context] |____________ep-context <-----------[endpoint contexts] |____________ep#ep_index <--------[root for an endpoint] |______________cycle <------------------[ring cycle] |______________dequeue <--------[ring dequeue pointer] |______________enqueue <--------[ring enqueue pointer] |______________trbs <-------------------[ring trbs] Signed-off-by: Lu Baolu <baolu.lu@linux.intel.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
