* USB: usbfs: export the URB_NO_INTERRUPT flag to userspaceAlan Stern2008-04-25
| | | | | | | | | | | | | | | | | | | | This patch (as1079) cleans up the way URB_* flags are exported in usbfs. The URB_NO_INTERRUPT flag is now exported (this is the only behavioral change). USBDEVFS_URB_* macros are added for URB_NO_FSBR, URB_ZERO_PACKET, and URB_NO_INTERRUPT, making explicit the fact that the kernel accepts them. The flag matching takes into account that the URB_* values may change as the kernel evolves, whereas the USBDEVFS_URB_* values must remain fixed since they are a user API.

* USB: fix compile problems in ehci-hcdAlan Stern2008-04-25
| | | | | | | | | | | | | | | This patch (as1072) fixes some recently-introduced compile problems that show up in ehci-hcd when CONFIG_PM is turned off. PORT_WAKE_BITS needs to be defined always. ehci_port_power() is called during initialization by all the EHCI variants other than the PCI version, in which it is "defined but not used". So add a call to it. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: ehci: qh_completions cleanup and bugfixDavid Brownell2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Simplify processing of completed qtds, and correct handling of short reads, by removing two state variables: - "qtd_status" wasn't needed. The current URB's status is either OK (-EINPROGRESS) or some fault status. Once a fault appears, the queue halts and any later QTDs are immediately removed, so no temporary status is needed. (Or for typical short reads, it's not treated as a fault, so no queue halt is needed.) - "do_status" was erroneous. Because of how the queue is set up, short control reads can (and should!) be treated like full size reads, and cleaned up the usual way. The status stage will be executed transparently, and usbcore handles the choice of whether to report this status as unexected. The "do_status" problem caused a rather perplexing timing-dependent problem with usbtest case 10. Sometimes it would make the controller skip a dozen transactions while (wrongly) trying to clean up after a short transfer. Fortunately, removing a dcache contention issue made this become trivial to reproduce (on one test rig), so enough clues finally presented themselves ... I think this has been around for a very long time, but was worsened by recent urb->status changes.

* USB: cdc-acm: signedness fixDavid Brownell2008-04-25
| | | | | | | | | | | | | | | | | | | Fix bogus assignment of "unsigned char *" to "char *": preserve unsignedness. These values are used directly as descriptor lengths when iterating through the buffer, so this *could* cause oddness that potentially includes oopsing. (IMO not likely, except as part of a malicious device...) Fix the bogus warning in CDC ACM which highlighted this problem (by showing a negative descriptor type). It uses the undesirable legacy err() for something that's not even an error; switch to use dev_dbg, and show descriptor types in hex notation to match the convention for such codes.

* USB: don't explicitly reenable root-hub status interruptsAlan Stern2008-04-25
| | | | | | | | | | | | | | | | | This patch (as1069b) 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.

* USB: OHCI: turn off RD when remote wakeup is disabledAlan Stern2008-04-25
| | | | | | | | | | | | | This patch (as1068b) disables the RD interrupt flag when an OHCI root hub is suspended with remote wakeup disabled. Although the spec clearly states that this flag permits the controller to issue an interrupt when a resume request from downstream is detected and not when a local status change occurs, some controllers mistakenly use it for both types of event.

* USB: HCDs use the do_remote_wakeup flagAlan Stern2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | When a USB device is suspended, whether or not it is enabled for remote wakeup depends on the device_may_wakeup() setting. The setting is then saved in the do_remote_wakeup flag. Later on, however, the device_may_wakeup() value can change because of user activity. So when testing whether a suspended device is or should be enabled for remote wakeup, we should always test do_remote_wakeup instead of device_may_wakeup(). This patch (as1076) makes that change for root hubs in several places. The patch also adjusts uhci-hcd so that when an autostopped controller is suspended, the remote wakeup setting agrees with the value recorded in the root hub's do_remote_wakeup flag. And the patch adjusts ehci-hcd so that wakeup events on selectively suspended ports (i.e., the bus itself isn't suspended) don't turn on the PME# wakeup signal.

* USB: ehci shutdown refactoredSarah Sharp2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch refactors some shutdown code so it can be shared between ehci_stop() and ehci_shutdown(). This also fixes a couple potential bugs: - ehci_shutdown() was not locking ehci->lock before halting the HC. - ehci_shutdown() didn't disable the watchdog and IAA timers. - ehci_stop() was resetting the host controller when it may have been running, which the EHCI spec says "may result in undefined behavior". ehci_stop() was calling port_power() to turn off the ports, which waited 20ms after applying the port change. The msleep was for the case where the HC might take 20ms to turn the ports on; since we're shutting them off, we can avoid the msleep and just use ehci_turn_off_ports(). ehci_stop() doesn't need to clear the intr_enable register or revert ownership of the companion controllers to the BIOS, because the host controller reset should have done that. There might be a buggy host controller that doesn't follow the reset rules, but for now we assume it's redundant code and remove it. [ A subsequent patch will cancel the timers later ... this version carries forward existing bugs where timers could get re-armed after they're canceled. ] Signed-off-by: Sarah Sharp <sarah.a.sharp@intel.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

| | | | | | | | | | | | | | | | This patch (as1075) changes dummy-hcd to dynamically allocate its platform_device structures, using the core platform_device_alloc() interface. This is what it should have done all along, because the dynamically-allocated structures have a release method in the driver core and are therefore immune to being released after the module has been unloaded.

* USB: rework sysfs removal of interface filesAlan Stern2008-04-25
| | | | | | | | | | | | | | | | | | Removing an interface's sysfs files before unregistering the interface doesn't work properly, because usb_unbind_interface() will reinstall altsetting 0 and thereby create new sysfs files. This patch (as1074) removes the files after the unregistration is finished. It's not quite as clean, but at least it works. Also, there's no need to check if an interface has been registered before removing its sysfs files. If it hasn't been registered then the files won't have been created, so usb_remove_sysfs_intf_files() will simply do nothing.

* USB: OHCI: host-controller resumes leave root hub suspendedAlan Stern2008-04-25
| | | | | | | | | | | | | | | | | | | | | | | Drivers in the ohci-hcd family should perform certain tasks whenever their controller device is resumed. These include checking for loss of power during suspend, turning on port power, and enabling interrupt requests. Until now these jobs have been carried out when the root hub is resumed, not when the controller is. Many drivers work around the resulting awkwardness by automatically resuming their root hub whenever the controller is resumed. But this is wasteful and unnecessary. To simplify the situation, this patch (as1066) adds a new core routine, ohci_finish_controller_resume(), which can be used by all the OHCI-variant drivers. They can call the new routine instead of resuming their root hubs. And ohci-pci.c can call it instead of using its own special-purpose handler.

* USB: clarify usage of hcd->suspend/resume methodsAlan Stern2008-04-25
| | | | | | | | | | | | | | | The .suspend and .resume method pointers in struct usb_hcd have not been fully understood by host-controller driver writers. They are meant for use with PCI controllers; other platform-specific drivers generally should not refer to them. To try and clarify matters, this patch (as1065) renames those methods to .pci_suspend and .pci_resume. It eliminates corresponding dead code and bogus references in the ohci-ssb and u132-hcd drivers.
