xhci: Remove more doorbell-related reads

The unused space in the doorbell is now marked as RsvdZ, not RsvdP, so
we can avoid reading the doorbell before writing it.

Update the doorbell-related defines to produce the entire doorbell value
from a single macro.  Document the doorbell format in a comment.

13 years agousb: Realloc xHCI structures after a hub is verified.
Sarah Sharp [Thu, 23 Dec 2010 19:12:42 +0000 (11:12 -0800)]
usb: Realloc xHCI structures after a hub is verified.

When there's an xHCI host power loss after a suspend from memory, the USB
core attempts to reset and verify the USB devices that are attached to the
system.  The xHCI driver has to reallocate those devices, since the
hardware lost all knowledge of them during the power loss.

When a hub is plugged in, and the host loses power, the xHCI hardware
structures are not updated to say the device is a hub.  This is usually
done in hub_configure() when the USB hub is detected.  That function is
skipped during a reset and verify by the USB core, since the core restores
the old configuration and alternate settings, and the hub driver has no
idea this happened.  This bug makes the xHCI host controller reject the
enumeration of low speed devices under the resumed hub.

Therefore, make the USB core re-setup the internal xHCI hub device
information by calling update_hub_device() when hub_activate() is called
for a hub reset resume.  After a host power loss, all devices under the
roothub get a reset-resume or a disconnect.

13 years agoxhci: Resume bus on any port status change.
Sarah Sharp [Tue, 14 Dec 2010 21:24:55 +0000 (13:24 -0800)]
xhci: Resume bus on any port status change.

The original code that resumed the USB bus on a port status change would
only do so when there was a device connected to the port.  If a device was
just disconnected, the event would be queued for khubd, but khubd wouldn't
run.  That would leave the connect status change (CSC) bit set.

If a USB device was plugged into that same port, the xHCI host controller
would set the current connect status (CCS) bit.  But since the CSC bit was
already set, it would not generate an interrupt for a port status change
event.  That would mean the user could "Safely Remove" a device, have the
bus suspend, disconnect the device, re-plug it in, and then the device
would never be enumerated.

Plugging in a different device on another port would cause the bus to
resume, and khubd would notice the re-connected device.  Running lsusb
would also resume the bus, leading users to report the problem "went away"
when using diagnostic tools.

The solution is to resume the bus when a port status change event is
received, regardless of the port status.

Thank you very much to Maddog for helping me track down this Heisenbug.
