| |
Hello All,
I have a question regarding the wait queues. I have a driver pxausb_core.o which is the core driver which does all USB endpoint handling and hardware interaction. I have one more driver on top of it usb-serial which provides for the user-level interaction(like read, write, ioctl). I have implemented a blocking ioctl, which sends events about the state of USB device(enumerated, suspended, disconnected, etc). For this ioctl, i have declared a wait_queue and initialized (using init_waitqueue_head() func.) in the usb_ctl.c which is part of pxausb_core.o. (it has usb_send.c, usb_recv.c, usb_ctl.c, usb_ep0.c). I am using that wait_queue variable in usb-ser.c.
I just wanted to clarify myself whether the wait queues can be shared between two driver modules.
