Alan Stern [Thu, 9 Oct 2008 19:40:23 +0000]
USB: OHCI: fix endless polling behavior

This patch (as1149) fixes an obscure problem in OHCI polling.  In the
current code, if the RHSC interrupt status flag turns on at a time
when RHSC interrupts are disabled, it will remain on forever:

The interrupt handler is the only place where RHSC status
gets turned back off;

The interrupt handler won't turn RHSC status off because it
doesn't turn off status flags if the corresponding interrupt
isn't enabled;

RHSC interrupts will never get enabled because
ohci_root_hub_state_changes() doesn't reenable RHSC if RHSC
status is on!

As a result we will continue polling indefinitely instead of reverting
to interrupt-driven operation, and the root hub will not autosuspend.
This particular sequence of events is not at all unusual; in fact
plugging a USB device into an OHCI controller will usually cause it to
occur.

Of course, this is a bug.  The proper thing to do is to turn off RHSC
status just before reading the actual port status values.  That way
either a port status change will be detected (if it occurs before the
status read) or it will turn RHSC back on.  Possibly both, but that
won't hurt anything.

We can still check for systems in which RHSC is totally broken, by
re-reading RHSC after clearing it and before reading the port
statuses.  (This re-read has to be done anyway, to post the earlier
write.)  If RHSC is on but no port-change statuses are set, then we
know that RHSC is broken and we can avoid re-enabling it.

Julien Brunel [Wed, 24 Sep 2008 16:00:36 +0000]
USB: isp1760: Use an IS_ERR test rather than a NULL test

In case of error, the function isp1760_register returns an ERR
pointer, but never returns a NULL pointer. So after a call to this
function, a NULL test should be replaced by an IS_ERR test. Moreover,
we have noticed that:
(1) the result of isp1760_register is assigned through the function
pci_set_drvdata without an error test,
(2) if the call to isp1760_register fails, the current function
(isp1761_pci_probe) returns 0, and if it succeeds, it returns -ENOMEM,
which seems odd.

Thus, we suggest to move the test before the call to pci_set_drvdata
to correct (1), and to turn it into a non IS_ERR test to correct (2).

The semantic match that finds this problem is as follows:

11 years agoUSB: improve ehci_watchdog's side effect in CPU power management
Yi Yang [Thu, 25 Sep 2008 09:25:44 +0000]
USB: improve ehci_watchdog's side effect in CPU power management

ehci_watchdog will wake up CPU very frequently so that CPU
stays at C3 very short, average residence time is about 50
ms on Aspire One, but we expect it should be about 1 second
or more, so this kind of periodic timer is very bad for power
saving.

We can't remove this timer because of some bad USB controller
chipset, but at least we should reduce its side effect to as
possible as low.

This patch can make CPU stay at C3 longer, average residence time
is about twice as long as original.

Please consider to apply it, thanks

Alan Stern [Thu, 25 Sep 2008 20:59:57 +0000]
USB: UHCI: improve scheduling of interrupt URBs

This patch (as1140) adds a little intelligence to the interrupt-URB
scheduler in uhci-hcd.  Right now the scheduler is stupid; every URB
having the same period is assigned to the same slot.  Thus a large
group of period-N URBs can fill their slot and cause -ENOSPC errors
even when all the lower-period slots are empty.

With the patch, if an URB doesn't fit in its assigned slot then the
scheduler will try using lower-period slots.  This will provide
greater flexibility.  As an example, the driver will be able to handle
more than just three or four mice, which the current driver cannot.

usbmon registers the notifier chain, takes the bus lock and then goes to

Unfortunately, if usb_mon gets initialized while USB bus discovery is

without USB locks), and the scan is going on and also finds the new bus,
resulting in a double sysfs registration, which then produces a WARNING.

USB: change hub initialization sleeps to delayed_work

This patch (as1137) changes the hub_activate() routine, replacing the
power-power-up and debounce delays with delayed_work calls.  The idea
is that on systems where the USB stack is compiled into the kernel
rather than built as modules, these delays will no longer block the
boot thread.  At least 100 ms is saved for each root hub, which can
add up to a significant savings in total boot time.

Arjan van de Ven was very pleased to see that this shaved 700 ms off
his computer's boot time.  Since his total boot time is on the order
of two seconds, the improvement is considerable.

devices.  These devices sometimes return less data than asked for and
then provide no sense data to explain the problem.  Currently
usb-storage leaves it up to the SCSI layer to decide how this should
be handled, and the SCSI layer interprets the lack of sense data to
mean that nothing went wrong.  But if we got less data than required
then something definitely _did_ go wrong, and we should say so.

The patch tells the SCSI layer to retry the command when this sort of
thing happens.  Retrying may not solve the underlying problem, but
it's better than believing that data was transferred when it wasn't.

usb: add Freescale QE/CPM USB peripheral controller driver

Some of Freescale SoC chips have a QE or CPM co-processor which
supports full speed USB.  The driver adds device mode support
of both QE and CPM USB controller to Linux USB gadget.  The
driver is tested with MPC8360 and MPC8272, and should work with

USB: drivers/usb/misc: Use an IS_ERR test rather than a NULL test

In case of error, the function backlight_device_register returns an
ERR pointer, but never returns a NULL pointer. So a NULL test that may
come after a call to this function should be strengthened by an IS_ERR
test.

Add a new mechanism to the composite gadget framework, letting

as a refcounted wrapper for the software pullup control.

A key example of why to use this mechanism involves functions that
require a userspace daemon.  Those functions shuld use this new
mechanism to prevent the gadget from enumerating until those daemons

USB: Let some USB host controllers get IRQ flags from resource

[This version fixes a thinko in the r8a66597 driver]

This patch let a few discrete USB host controllers drivers (isp116x-hcd,
r8a66597-hcd and sl811-hcd) obtain IRQ flags from their IORESOURCE_IRQ
resource if configured as such, much like it's been done for the smc91x
driver.

It spares people writing support for specific boards the burden to
configure the interrupt controller independantly, and keeps all IRQ
related information in a single resource.

HCD that are integrally part of a SoC have been left aside, as there
is probably no "wiring" options...

Tested on an Xscale PXA-255 based platform with isp116x-hcd.
