2008-08-21USB: automatically enable RHSC interruptsAlan Stern
This patch (as1069c) changes the way OHCI root-hub status-change interrupts are enabled. Currently a special HCD method, hub_irq_enable(), is called when the hub driver is finished using a root hub. This approach turns out to be subject to races, resulting in unnecessary polling. The patch does away with the method entirely. Instead, the driver automatically enables the RHSC interrupt when no more status changes are present. This scheme is safe with controllers using level-triggered semantics for their interrupt flags.

2008-08-13USB: quirk PLL power down modeLibin Yang
On some AMD 700 series southbridges, ISO OUT transfers (such as audio playback through speakers) on the USB OHCI controller may be corrupted when an A-Link express power saving feature is active. PLL power down mode in conjunction with link power management feature L1 being enabled is the bad combination ... this patch prevents them from being enabled when ISO transfers are pending.

2008-08-13usb: ISP1760: improve pre-fetch timingEnrico Scholz
ISP1760 requires a delay of 90ns between programming the address and reading the data. Current driver solves this by a mdelay(1) which is very heavy weighted and slow. This patch applies the workaround from the ISP1760 FAQ by using two different banks for PTD and payload data and using a common wait for them. This wait is done by an additional ISP1760 access (whose timing constraints guarantee the 90ns delay). This improves speed when reading from an USB stick from: $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638 real 1m 15.43s user 0m 0.44s sys 0m 39.46s to $ time dd if=/dev/sda of=/dev/zero bs=65536 count=1638 real 0m 18.53s user 0m 0.16s sys 0m 12.97s [bigeasy@linutronix.de: fixed comment formating, moved define into header file, obey 80 char rule] Signed-off-by: Enrico Scholz <enrico.scholz@sigma-chemnitz.de> Signed-off-by: Sebastian Siewior <bigeasy@linutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2008-08-13USB: OHCI: fix system hang caused by earlier patchAlan Stern
This patch (as1114) fixes a problem that was revealed by an earlier patch (as1069b). Some broken controllers seem never to turn off their RHCS interrupt status bit, even when told to do so. As a result they generate an interrupt storm and hang the system. The patch avoids enabling RHSC interrupt requests when the RHCS status bit is already set. This should have no adverse affects on normal controllers, since they won't set the status bit until a root-hub status change actually occurs, in which case we wouldn't enable RHSC interrupt requests anyway -- we would wait until the status change had been processed and cleared.

Various cleanups and fixes to the i2c code in ohci-pnx4008: * Delete empty isp1301_command. The i2c driver command implementation is optional, so there's no point in providing an empty implementation. * Give a name to isp1301_driver. I'm surprised that i2c-core accepted to register this driver at all. I've chosen "isp1301_pnx" as the name, because it's not a generic ISP1301 driver (much like the isp1301_omap driver.) We might want to make the name even more specific (but "isp1301_ohci_pnx4008" doesn't fit.) * The ISP1301 is definitely not a hardware monitoring device. * Fix a memory leak on failure in isp1301_attach. If i2c_attach_client fails, the client is not registered so isp1301_detach is never called and the i2c_client memory is lost. * Use strlcpy instead of strcpy.

2008-07-21USB: ehci-hcd unlink speedupsDavid Brownell
This patch fixes some performance bugs observed with some workloads when unlinking EHCI queue header (QH) descriptors from the async ring (control/bulk schedule). The mechanism intended to defer unlinking an empty QH (so there is no penalty in common cases where it's quickly reused) was not working as intended. Sometimes the unlink was scheduled: - too quickly ... which can be a *strong* negative effect, since that QH becomes unavailable for immediate re-use; - too slowly ... wasting DMA cycles, usually a minor issue except for increased bus contention and power usage; Plus there was an extreme case of "too slowly": a logical error in the IAA watchdog-timer conversion meant that sometimes the unlink never got scheduled. The fix replaces a simple counter with a timestamp derived from the controller's 8 KHz microframe counter, and adjusts the timer usage for some issues associated with HZ being less than 8K. (Based on a patch originally by Alan Stern, and good troubleshooting from Leonid.)

2008-07-21USB: ohci_hcd hang: submit vs. rmmod racePete Zaitcev
If we do rmmod ohci_hcd while an application is doing something, the following may happen: - a control URB completes (in finish_urb) and the ohci's endpoint is set into ED_UNLINK in ed_deschedule - same URB is (re)submitted because of the open/close loop or other such application behaviour - rmmod sets the state to HC_STATE_QUESCING - finish_unlinks happens at next SOF; normally it would set ed into ED_IDLE and immediately call ed_schedule (since URB had extra TDs queued), which sets it into ED_OPER. But the check in ed_schedule makes it fail with -EAGAIN (which is ignored) - from now on we have a dead URB stuck; it cannot even be unlinked because the ed status is not ED_OPER, and thus start_ed_unlink is not invoked. This patch removes the check. In 2.6.25, all callers check for __ACTIVE bit before invoking ed_schedule, which is more appropriate. Alan Stern and David Brownell approved of this (cautiously).

This reverts commit e872154921a6b5256a3c412dd69158ac0b135176. Andrey Borzenkov reports that it resulted in a totally hung machine for him when loading the OHCI driver. Extensive netconsole capture with SysRq output shows that modprobe gets stuck in ohci_hub_status_data() when probing and enabling the OHCI controller, see for example http://lkml.org/lkml/2008/7/5/236 for an analysis.

2008-07-03USB: ohci - record data toggle after unlinkDavid Brownell
This patch fixes a problem with OHCI where canceling bulk or interrupt URBs may lose track of the right data toggle. This seems to be a longstanding bug, possibly dating back to the Linux 2.4 kernel, which stayed hidden because (a) about half the time the data toggle bit was correct; (b) canceling such URBs is unusual; and (c) the few drivers which cancel these URBs either [1] do it only as part of shutting down, or [2] have fault recovery logic, which recovers. For those transfer types, the toggle is normally written back into the ED when each TD is retired. But canceling bypasses the mechanism used to retire TDs ... so on average, half the time the toggle bit will be invalid after cancelation. The fix is simple: the toggle state of any canceled TDs are propagated back to the ED in the finish_unlinks function. (Issue found by leonidv11@gmail.com ...)

This patch fixes a regression in the EHCI driver's TIMER_IO_WATCHDOG behavior. The patch "USB: EHCI: add separate IAA watchdog timer" changed how that timer is handled, so that short timeouts on the remaining timer (unfortunately, overloaded) would never be used. This takes a more direct approach, reorganizing the code slightly to be explicit about only the I/O watchdog role now being overridable. It also replaces a now-obsolete comment describing older timer behavior.
