This patch (as1099) fixes a performance regression in ehci-hcd. The fundamental problem is that queue headers get removed from the schedule too quickly, since the code checks for a counter advancing rather than making an actual time-based check. The latency involved in removing the queue header and then relinking it can severely degrade certain kinds of workloads. The patch replaces a simple counter with a timestamp derived from the controller's uframe value. In addition, the delay for unlinking an idle queue header is increased from 5 ms to 10 ms; since some controllers (nVidia) have a latency of up to 1 ms for unlinking, this reduces the relative impact from 20% to 10%. Finally, a logical error left over from the IAA watchdog-timer conversion is corrected. Now the driver will always either unlink an idle queue header or set up a timer to unlink it later. The old code would sometimes fail to do either.

This patch (as1098) changes the way ehci-hcd schedules its periodic Iso transfers. That the current scheduling code is wrong is clear on the face of it: Sometimes it returns -EL2NSYNC (meaning that an URB couldn't be scheduled because it was submitted too late), but it does this even when the URB_ISO_ASAP flag is set (meaning the URB should be scheduled as soon as possible). The new code properly implements as-soon-as-possible scheduling, assigning the next unexpired slot as the URB's starting point. It also is more careful about checking for Iso URB completion: It doesn't bother to check for activity during frames that are already over, and it allows for the possibility that some of the URB's packets may have raced the hardware when they were submitted and so never got used (the packet status is set to -EXDEV). This fixes problems several people have experienced with USB video applications.

This patch (as1097) fixes a bug in the remote-wakeup handling in ehci-hcd. The driver currently does not keep track of whether the change-suspend feature is enabled for each port; the feature is automatically reset the first time it is read. But recent changes to the hub driver require that the feature be read at least twice in order to work properly. A bit-vector is added for storing the change-suspend feature values.

This patch (as1096) fixes an annoying problem: When a full-speed or low-speed device is plugged into an EHCI controller, it fails to enumerate at high speed and then is handed over to the companion controller. But usbcore logs a misleading and unwanted error message when the high-speed enumeration fails. The patch adds a new HCD method, port_handed_over, which asks whether a port has been handed over to a companion controller. If it has, the error message is suppressed.

This patch (as1095) cleans up the HCD glue and several of the EHCI bus-glue files. The ehci->is_tdi_rh_tt flag is redundant, since it means the same thing as the hcd->has_tt flag, so it is removed and the other flag used in its place. Some of the bus-glue files didn't get the relinquish_port method added to their hc_driver structures. Although that routine currently doesn't do anything for controllers with an integrated TT, in the future it might. So the patch adds it where it is missing. Lastly, some of the bus-glue files have erroneous entries for their hc_driver's suspend and resume methods. These method pointers are specific to PCI and shouldn't be used otherwise. (The patch also includes an invisible whitespace fix.) Signed-off-by: NAlan Stern <stern@rowland.harvard.edu> Acked-by: NDavid Brownell <dbrownell@users.sourceforge.net>

This patch (as1094) changes the output of the "descriptors" binary attribute. Now it will contain the device descriptor followed by all the configuration descriptors, not just the descriptor for the current config. Userspace libraries want to have access to the kernel's cached descriptor information, so they can learn about device characteristics without having to wake up suspended devices. So far the only user of this attribute is the new libusb-1.0 library; thus changing its contents shouldn't cause any problems. This should be considered for 2.6.26, if for no other reason than to minimize the range of releases in which the attribute contains only the current config descriptor. Also, it doesn't hurt that the patch removes the device locking -- which was formerly needed in order to know for certain which config was indeed current.

There is a potential deadlock when the usb_generic driver is unbound from a device. The problem is that generic_disconnect() is called with the device lock held, and it removes a bunch of device attributes from sysfs. If a user task happens to be running an attribute method at the time, the removal will block until the method returns. But at least one of the attribute methods (the store routine for power/level) needs to acquire the device lock! This patch (as1093) eliminates the deadlock by moving the calls to create and remove the sysfs attributes from the usb_generic driver into usb_new_device() and usb_disconnect(), where they can be invoked without holding the device lock. Besides, the other sysfs attributes are created when the device is registered and removed when the device is unregistered. So it seems only fitting for the extra attributes to be created and removed at the same time.

Uninitialised Apple iSight drivers present with a distinctive USB ID. Once firmware has been uploaded, they disconnect and reconnect with a new ID. At this point they can be driven by the uvcvideo driver. As this is unique to the Apple cameras and not functionality shared by any other UVC devices, it makes sense to provide the firmware loading functionality in a separate driver. This driver will read an isight.fw file extracted from the Apple driver using the tools at http://bersace03.free.fr/ift/ and upload it to the camera. It will also handle the case where the device loses its firmware during hibernation and must have it reloaded.

According to the PCI Express specification, we must wait for at least 1 second after turning power off before taking any action that relies on power having been removed from the slot/adapter. For this, current pciehp wait for 1 second after issuing the power off command in hpc_power_off_slot() function. But waiting for 1 second in hpc_power_off_slot() can make pciehp probing slow-down because pciehp probe code calls hpc_power_off_slot() if the slot is not occupied just in case. We don't need to wait for 1 second at the pciehp probe time because there is no action on that empty slot. So move 1 second wait from hpc_power_off_slot() to the caller of hpc_power_off_slot().

Fix improper long wait for command completion in pciehp probing. As described in PCI Express specification, software notification is not generated if the command that occurs as a result of a write to the Slot Control register that disables software notification of command completed events. Since pciehp driver doesn't take it into account, such command is issued in pciehp probing, and it causes improper long wait for command completion.

Fix the "pciehp probing slow" problem reported from Jan C. Nordholz in http://bugzilla.kernel.org/show_bug.cgi?id=10751. The command completed bit in Slot Status register applies only to commands issued to control the attention indicator, power indicator, power controller, or electromechanical interlock. However, writes to other parts of the Slot Control register would end up writing to the control fields. Hence, any write to Slot Control register is considered as a command. However, if the controller doesn't support any of attention indicator, power indicator, power controller and electromechanical interlock, command completed bit would not set in writing to Slot Control register. In this case, we should not wait for command completed bit set, otherwise all commands would be considered not completed in timeout seconds (1 sec.). The cause of the problem is pciehp driver didn't take this situation into account. This patch changes pciehp to take it into account. This patch also add the check for "No Command Completed Support" bit in Slot Capability register. If it is set, we should not wait for command completed bit set as well. This problem seems to be revealed by the commit c27fb883 that fixed the bug that pciehp did not wait for command completed properly (pciehp just ignored the command completion event).

(1) Clear all events bits in Slot Status register to prevent the pciehp driver from detecting the spurious events that would have been occur before pciehp loading. (2) Add check whether slot initialization had been already done. This is short term fix. We need more structural fixes to install interrupt handler after slot initialization is done.

Some (broken?) platform assign the same slot name to multiple hotplug slots. On such system, slot initialization would fail because of name collision. The shpchp driver already have a "slot_with_bus" module option which adds the bus number into the slot name. This patch adds the message about this module option that will be displayed when slot name collision is detected.

There's a reason why using C99 initialisers even in the supposedly trivial structs is a good idea. Signed-off-by: NCarl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Signed-off-by: NDavid Woodhouse <dwmw2@infradead.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Move the AP7 cpufreq init to late_initcall() so that we don't try to bring up cpufreq until the governor is ready. x86 also uses late_initcall() for this. Signed-off-by: NHaavard Skinnemoen <haavard.skinnemoen@atmel.com>

Based on Roland's patch. This approach was suggested by Austin Clements from the very beginning, and then by Linus. As Austin pointed out, the execing task can be killed by SI_TIMER signal because exec flushes the signal handlers, but doesn't discard the pending signals generated by posix timers. Perhaps not a bug, but people find this surprising.
