bcm63xx_update_wedge(9) π
okay so welcome to the Kernel API Manual corner, bestie β this one is all about bcm63xx_update_wedge and its little wedge-status refresh moment β¨
β¨ NAME β¨
bcm63xx_update_wedge β iterate through wedged endpoints π no cap, thatβs the whole name.
β¨ SYNOPSIS β¨
void bcm63xx_update_wedge (struct bcm63xx_udc *udc , bool new_status );
β¨ ARGUMENTS β¨
udcβ a reference to the device controller, like the main character of our USB gadget story π«Άnew_statusβ itβs giving toggle energy:trueto "refresh" the wedge status;falseto clear it π
β¨ DESCRIPTION β¨
So on a SETUP interrupt, we need to manually "refresh" the wedge status, because the controller hardware is literally designed to automatically clear stalls in response to a CLEAR_FEATURE request from the host π like okay hardware, we see you.
On a RESET interrupt, we do want to restore all wedged endpoints. periodt. πΈ
