11 years agoUSB: OHCI: fix endless polling behavior
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:

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: fix tiny race exposed by the fastboot patches

usbmon registers the notifier chain, takes the bus lock and then goes to
scan the existing devices for hooking up.

Unfortunately, if usb_mon gets initialized while USB bus discovery is
going on, it's possible that usbmon gets a notifier on one cpu (which runs
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.

This patch is based on the following ideas:

1. Some usb devices (such as usb video class) have endpoints of high
   interval attribute, so reading "periodic" file need more debug buffer
   to accommodate the qh or itd schedule information.  For example, 4KB
   buffer is not enough for a single interrupt qh of 2ms period.

2. print a %p need 16 byte buffer on 64-bits arch, but 8 byte on 32-bits
   arch. Add a extra bonus for 64-bits arch.

This patch (as1134) attempts to improve the way we handle OHCI
controllers with broken Root Hub Status Change interrupt support.  In
these controllers the RHSC interrupt bit essentially never turns off,
making RHSC interrupts useless -- they have to remain permanently

Such controllers should still be allowed to turn off their root hubs
when no devices are attached.  Polling for new connections can
continue while the root hub is suspended.  The patch implements this
feature.  (It won't have much effect unless CONFIG_PM is enabled and

usb-storage: report underflow with no sense data

This patch (as1118) addresses a problem with certain USB mass-storage
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.
