The current port name "portX" is ambiguous. Before adding more port
messages rename ports to "-portX"
This is an ABI change, but the suspicion is that it will go unnoticed as
the port power control implementation has been broken since its
introduction. If however, someone was relying on the old
ClearPortFeature(PORT_POWER) on a usb3 port places the port in either a
DSPORT.Powered-off-detect / DSPORT.Powered-off-reset loop, or the
DSPORT.Powered-off state. There is no way to ensure that RX
terminations will persist in this state, so it is possible a device will
degrade to its usb2 connect
Once usb-acpi has set the port's connect type the usb_device's
->removable attribute can be set in the standard location
set_usb_port_removable().
This also changes behavior in the case where the firmware says that the
port connect type is unknown. In that case just use the default setting
determ
Assume that the peer of a superspeed port is the port with the same id
on the shared_hcd root hub. This identification scheme is required of
external hubs by the USB3 spec [1]. However, for root hubs, tier mismatch
may be in effect [2]. Tier mismatch can only be enumerated via platform
firmware.
The usb topology after this change will have symlinks between usb3 ports
and their usb2 peers, for example:
usb2/2-1/2-1:1.0/2-1-port1/peer => ../../../../usb3/3-1/3-1:1.0/3-1-port1
usb2/2-1/2-1:1.0/2-1-port2/peer => ../../../../usb3/3-1/3-1:1.0/3-1-port2
usb2/2-1/2-1:1.0/2-1-port3/peer => ../../.
ACPI identifies peer ports by setting their 'group_token' and
'group_position' _PLD data to the same value. If a platform has tier
mismatch [1] , ACPI can override the default (USB3 defined) peer port
association for internal hubs. External hubs follow the default peer
association scheme.
Locati
Given that root hub port peers are already established, external hub peer
ports can be determined by traversing the device topology:
1/ ascend to the parent hub and find the upstream port_dev
2/ walk ->peer to find the peer port
3/ descend to the peer hub via ->child
4/ find the port with the m
A hub indicates whether it supports per-port power control via the
wHubCharacteristics field in its descriptor. If it is not supported
a hub will still emulate ClearPortPower(PORT_POWER) requests by
stopping the link state machine. However, since this does not save
power do not bother suspending.
Per Alan's request this is the first half of the series that addresses
the following disconnect scenarios when attempting to use port
power-off. These 8 patches address scenario 1. Scenarios 2 and 3 are
addressed in part2 of this series (to be re-posted once part1 is
accepted).

This patch adds a debug print in the transfer dequeue case where a

It also adds the transfer ID to some debug prints and prints error codes

This set of patches fixes some issues with the URB dequeue process in
the HWA. In particular, problems that occur when unplugging the HWA
dongle while transferring data to a device. The last patch in the set
is just code cleanup to hopefully make this case a little less error
prone.

This patch takes a reference to the wa_xfer object in wa_urb_dequeue to
prevent the urb giveback code from completing the xfer and freeing it
while wa_urb_dequeue is executing. It also checks for done at the start
to avoid a double completion scenario. Adding the check for done in
urb_dequeue
This patch adds error checking to the abort request callback to forcibly
clean up the dequeued transfers if the abort request failed. The
wa_complete_remaining_xfer_segs was modified so that it could be used in
this situation as well. This fixes a stranded URB/PNP hang when the HWA
is unplugg
This patch adds ref counting to sections of code that operate on struct
wa_xfer objects that were missing it. Specifically, error handling
cases need to be protected from freeing the xfer while it is still in
use elsewhere. This fixes a kernel panic that can occur when pulling
the HWA dongle whil
This patch adds a convenience function for the commonly performed task
of marking a transfer segment as done. It combines the 3 steps of
setting the segment status, incrementing the segs_done field of the
transfer and checking if the completed segment results in the transfer
also being done.
