usb-ehci: add queue data struct
Add EHCIQueue struct, move the fields needed to track the queue stateinto that struct. Pass the new struct instead of ehci state down tofunctions which handle the queue state. Lot of variable references havechanged due to that without an actual functional change....
usb-ehci: trace mmio and usbsts
This patch starts adding trace support to ehci. It tracesupdates of the status register (USBSTS), mmio access andcontroller reset.
It also adds functions to set and clear status register bitsand puts them in use everywhere....
usb-ehci: trace state machine changes
Add functions to get and set the current state of the state machine,add tracepoints there to trace state transitions. Add support fortraceing the queue heads and transfer descriptors as we look at them.
Drop a few DPRINTFs and all DPRINTF_ST lines, they are obsolete now....
usb-ehci: trace port state
Trace usb port operations (attach, detach, reset),drop a few obsolete DPRINTF's.
usb-ehci: improve mmio tracing
Add a separate tracepoint to log how register values change in responseto a mmio write. Especially useful for registers which have read-onlyor clear-on-write bits in them.
