This series is an attempt to avoid stop endpoint command failure
leading to xhci teardown with messages:

xHCI host not responding to stop endpoint command
xHCI host controller not responding, assume dead

Series is based on a discussion with Michal and Xu Rao:

https://lore.kernel.org/linux-usb/D9BA02889D046D23+20260617100957.2888108-1-raoxu@uniontech.com/

A Renesas xHC host with a device behind a disconnected hub failed to
complete a stop endoint command immediately after a endpoint soft
reset and restart. Michal had some plausible theories why stop endpoint
command issued immediately after endpoint restart fails after disconnect.

Many of these cases can be avoided as xhci driver knows the rootport
link state and can avoid futile transfer retry and recovery on link
error or disconnect

I don't have a easy way to reproduce this myself, all testing is
welcome

Thanks
Mathias

Driver already prevents useless transfer retry and endpoint recovery
for devices directly connected to a root port with link errors.

These devices are either disconnecting or will be reset. Link is gone.

Move the flag indicating link error from the xhci device structure to
the root port strucure, allowing all child devices behind hubs to easily
check for root port link errors, avoiding useless transfer retries and
endpoint recovery.

This extends the previous endpoint recovery prevention in
commit b8c3b718087b ("usb: xhci: Don't try to recover an endpoint if port is in error state.")
Only root port link errors can be detected early by xhci driver,
not link errors between external hubs and their children.

Prevent transfer retry and endpoint recovery if the device or its parent
disconnected from the roothub. Just like link error case.

There is a suspicion some xHC controllers may stop processing endpoint
related commands after the last USB device disconnects from the host.

Disconnect often causes transaction errors, xhci driver tries to (soft)
reset and restart the endpoint to recover it.
Hub driver again will cancel all pending URBs once disconnect is detected,
stopping the endpoint right after (soft) reset restarted it.
xHC controller sometimes fail to complete the stop endpoint command,
leading to driver timing out, and tearing down xhci

Prevent extra endpoint (soft) reset after xhci driver is aware of the
parent roothub port disconnect.

Avoid all extra endpoint state changes after the roothub link
is lost due to disconnect or link error, and endpoint is known
to be in a non-running state.

Rapid endpoint state changes involving endpoint reset, restart, and
stopping the endpoint have caused xHC failures to complete stop
endpoint command. xhci driver sees this as a fatal flaw and tears
down xhci.

These endpoint state changes are normally part of recovery from
transaction errors or URB cancel.
In this case recovery is not needed.

Add an endpoint state called EP_DROP_PENDING.
Set ep->ep_state |= EP_DROP_PENDING when an endpoint is found in a
halted or stopped non-running state, and the roothub link is
lost. Prevent endpoint from restarting.

URB cancel doesn't need to stop the endpoint if EP_DROP_PENDONG is set.
URBs can be given back directly.
Endpoint is, and will remain stopped until it's dropped.

Hi Mathias,

I tested this series on the Renesas uPD720201 xHCI controller with the
GenesysLogic hub and RTL8153 device behind it.

The original failure is no longer reproduced. After unplugging the hub,
the xHCI driver no longer tears down the host, and I no longer see:

  xHCI host not responding to stop endpoint command
  xHCI host controller not responding, assume dead

The log also shows the new EP_DROP_PENDING path is used during disconnect,
for example cancelled TDs are invalidated directly instead of queuing a
futile Stop Endpoint command.

The full test log is included below for reference.

Thanks for testing.

Do you think this series is enough for the Renesas uPD720201 controller issue
and we can skip the 'Disable soft retry' patch?

Thanks

Yes, I think this series is sufficient for the uPD720201 issue I
reported, and the "Disable soft retry" patch can be skipped.

I tested the series with soft retry still enabled, and the original
host teardown failure was no longer reproduced.
