Alan Stern [Mon, 20 Nov 2006 16:14:30 +0000 (11:14 -0500)]
USB hub: simplify remote-wakeup handling

This patch (as817) simplifies the remote-wakeup processing in the hub
driver.  Now instead of using a specialized code path, it relies on
the standard USB resume routines.  The hub_port_resume() function does
an initial get_port_status() to see whether the port has already
resumed itself (as it does when a remote-wakeup request is sent).
This will slow down handling of other resume events slightly, but not
enough to matter.

The patch also changes the hub_port_status() routine, making it return
an error if a short reply is received.

OHCI: make autostop conditional on CONFIG_PM

Unlike UHCI, OHCI does not exert any DMA load on the system when no

an autostop other than the power savings, so we shouldn't compile the
necessary code unless CONFIG_PM is enabled.

This patch (as820) makes the root-hub suspend and resume routines
conditional on CONFIG_PM.  It also prevents autostop from activating

Alan Stern [Thu, 9 Nov 2006 19:42:16 +0000 (14:42 -0500)]
EHCI: Fix root-hub and port suspend/resume problems

This patch (as738b) fixes numerous problems in the controller/root-hub
suspend/resume/remote-wakeup support in ehci-hcd:

The bus_resume() routine should wake up only the ports that
were suspended by bus_suspend().  Ports that were already
suspended should remain that way.

The interrupt mask is used to detect loss of power in the
bus_resume() routine (if the mask is 0 then power was lost).
However bus_suspend() always sets the mask to 0.  Instead the
mask should retain its normal value, with port-change-detect
interrupts disabled if remote wakeup is turned off.

The interrupt mask should be reset to its correct value at the
end of bus_resume() regardless of whether power was lost.

bus_resume() reinitializes the operational registers if power
was lost.  However those registers are not in the aux power
well, hence they can lose their values whenever the controller
is put into D3.  They should always be reinitialized.

When a port-change interrupt occurs and the root hub is
suspended, the interrupt handler should request a root-hub
resume instead of starting up the controller all by itself.

There's no need for the interrupt handler to request a
root-hub resume every time a suspended port sends a
remote-wakeup request.

The pci_resume() method doesn't need to check for connected
ports when deciding whether or not to reset the controller.
It can make that decision based on whether Vaux power was
maintained.

Even when the controller does not need to be reset,
pci_resume() must undo the effect of pci_suspend() by
re-enabling the interrupt mask.

If power was lost, pci_resume() must not call ehci_run().
At this point the root hub is still supposed to be suspended,
not running.  It's enough to rewrite the command register and
set the configured_flag.

Allright. As Greg KH suggested I split this big patch into smaller ones to

split it on a 'patch per file' basis. All those patches clean redundant 'if' before
usb_unlink/free/kill_urb():

if (urb)
usb_free_urb(urb); /* unlink / free / kill */

I decided not to touch bigger 'if's like

if (urb) {
usb_kill_urb(urb);
usb_free_urb(urb);
urb = NULL;
}

as that would be probably too intrusive. One of patches also fixes

USB: makes usb_endpoint_* functions inline.

We have no benefits of having the usb_endpoint_* functions as functions,
but making them inline saves text and data segment sizes:

text    data     bss     dec     hex filename
14893634 3108770 1108840 19111244 1239d4c vmlinux.func
14893185 3108566 1108840 19110591 1239abf vmlinux.inline

CONFIG_MODULES, CONFIG_CC_OPTIMIZE_FOR_SIZE, CONFIG_REGPARM options set.
USB support is fully enabled (while most of the other drivers are not),
and that kernel has most of the USB code ported to use the endpoint
functions.

That happens because a call to those functions are expensive (in terms
of bytes), while the function's size is smaller or have the same 'size' of
the call.

USB core: don't match interface descriptors for vendor-specific devices

This patch (as804) makes USB driver matching ignore the interface
class, subclass, and protocol if the device class is Vendor Specific.
Drivers can override this policy by specifying a Vendor ID as part
of the match; then vendor-specific matches are allowed.

Linus Walleij has reported a problem this patch fixes.  When a
particular mass-storage device is switched from mass-storage mode to
Media Transfer Protocol, the interface class remains set to mass-storage
and usb-storage binds to it erroneously, even though the device class
changes to Vendor-Specific.

This may cause a problem for some drivers until their match records can
be updated to include Vendor IDs.  But if it does, then those records
were broken to begin with.

17 years agousb hub: fix root hub code so it takes more than 15 devices per root hub
inaky@linux.intel.com [Thu, 12 Oct 2006 03:05:59 +0000 (20:05 -0700)]
usb hub: fix root hub code so it takes more than 15 devices per root hub

Wireless USB Host Controllers accept a large number of devices per
host, which shows up as a large number of ports in its root hub.

When the number of ports in a hub device goes over 16, the activation
of the hub fails with the cryptic message in klogd.

hub 2-0:1.0: activate --> -22

Following this further, it was seen that:

hub_probe()
  hub_configure()
    generates pipe number

    pseudo allocates buffer 'maxp' bytes in size using usb_maxpacket()

      The endpoint descriptor for a root hub interrupt endpoint is
      declared in
      drivers/usb/core/hcd.c:hs_rh_config_descriptor and declares it
      to be size two (supporting 15 devices max).

    hub_activate()
      usb_hcd_submit_urb()
        rh_urb_enqueue()
          urb->pipe is neither int nor ctl, so it errors out
            rh_queue_status()
              Returns -EINVAL because the buffer length is smaller
              than the minimum needed to report all the hub port
              bits as in accordance with USB2.0[11.12.3]. There has
              to be trunc((PORTS + 1 + 7) / 8) bytes of space at
              least.

Alan Stern confirmed that the reason for reading maxpktsize and not
the right amount is because some hubs are known to return more data
and thus cause overflow.

So this patch simply changes the code to make the interrupt endpoint's
max packet size be at least the minimum required by USB_MAXCHILDREN
(instead of a fixed magic number) and add documentation for that. This
way we are always ahead of the limit.
