Functions | |
| void | usb_init_controller () |
| Initializes one controller, called by usb_init for every controller. eax -> PCIDEV structure for the device. More... | |
| void | get_phys_addr () |
| Helper function, calculates physical address including offset in page. More... | |
| void | usb_subscribe_control () |
| Put the given control/bulk pipe in the wait list; called when the pipe structure is changed and a possible hardware cache needs to be synchronized. When it will be known that the cache is updated, usb_subscription_done procedure will be called. More... | |
| void | usb_subscribe_periodic () |
| Same as usb_subscribe_control, but for interrupt/isochronous pipe. More... | |
| void | usb_subscription_done () |
| Called after synchronization of hardware cache with software changes. Continues process of device enumeration based on when it was delayed due to call to usb_subscribe_control. More... | |
| void | usb_test_pending_port () |
| This function is called when a new device has either passed or failed first stages of configuration, so the next device can enter configuration process. More... | |
| void | usb_disconnect_stage2 () |
| This procedure is regularly called from controller-specific ProcessDeferred, it checks whether there are disconnected events and if so, process them. More... | |
| void | usb_device_disconnected () |
| Initial stage of disconnect processing: called when device is disconnected. More... | |
| void | usb_process_wait_lists () |
| Called from controller-specific ProcessDeferred, processes wait-pipe-done notifications, returns whether there are more items in wait queues. in: esi -> usb_controller out: eax = bitmask of pipe types with non-empty wait queue. More... | |
| void | usb_process_one_wait_list () |
| Helper procedure for usb_process_wait_lists; does the same for one wait queue. in: esi -> usb_controller, edx=0 for *Async, edx=4 for *Periodic list out: CF = issue new request. More... | |
| void | usb_find_ehci_companion () |
| Called from USB1 controller-specific initialization. Finds EHCI companion controller for given USB1 controller. in: bl = PCI device:function for USB1 controller, bh = PCI bus out: eax -> usb_controller for EHCI companion. More... | |
| void | usb_get_tt () |
| Find Transaction Translator hub and port for the given device. in: edx = parent hub for the device, ecx = port for the device out: edx = TT hub for the device, ecx = TT port for the device. More... | |
