* Revert "USB: don't explicitly reenable root-hub status interrupts"Linus Torvalds2008-07-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | 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. The problem appears to be an interrupt flood triggered by the commit that gets reverted, and Andrey confirmed that the revert makes things work for him again.

* USB: don't explicitly reenable root-hub status interruptsAlan Stern2008-04-241-1/+0
| | | | | | | | | | | | | | | | | 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: host-controller resumes leave root hub suspendedAlan Stern2008-04-241-42/+1
| | | | | | | | | | | | | | | | | | | | | | | 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 Stern2008-04-241-3/+2
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | This patch (as1063) fixes a bug in the way ohci-hcd resumes its controllers. It leaves the Master Interrupt Enable bit turned off. If the root hub is resumed immediately this won't matter. But if the root hub is suspended (say because no devices are plugged in), it won't ever wake up by itself.

* USB: OHCI handles more ZFMicro quirksMike Nuss2007-10-121-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ZF Micro OHCI controller exhibits unexpected behavior that seems to be related to high load. Under certain conditions, the controller will complete a TD, remove it from the endpoint's queue, and fail to add it to the donelist. This causes the endpoint to appear to stop responding. Worse, if the device is removed while in that state, OHCI will hang while waiting for the orphaned TD to complete. The situation is not recoverable without rebooting. This fix enhances the scope of the existing OHCI_QUIRK_ZFMICRO flag: 1. A watchdog routine periodically scans the OHCI structures to check for orphaned TDs. In these cases the TD is taken back from the controller and completed normally. 2. If a device is removed while the endpoint is hung but before the watchdog catches the situation, any outstanding TDs are taken back from the controller in the 'sanitize' phase. The ohci-hcd driver used to print "INTR_SF lossage" in this situation; this changes it to the universally accurate "ED unlink timeout". Other instances of this message presumably have different root causes. Both this Compaq quirk and a NEC quirk are now properly compiled out for non-PCI builds of this driver.

* USB: Fix NEC OHCI chip silicon bugMichael Hanselmann2007-07-121-0/+16
| | | | | | | | | | | | | | This patch fixes a silicon bug in some NEC OHCI chips. The bug appears at random times and is very, very difficult to reproduce. Without the following patch, Linux would shut the chip and its associated devices down. In Apple PowerBooks this leads to an unusable keyboard and mouse (SSH still working).

* USB: EHCI, OHCI: handover changesAlan Stern2007-07-121-1/+40
| | | | | | | | | | | | | | | | | | | This patch (as887) changes the way ehci-hcd and ohci-hcd handle a loss of VBUS power during suspend. In order for the USB-persist facility to work correctly, it is necessary for low- and full-speed devices attached to a high-speed port to be handed back to the companion controller during resume processing. This entails three changes: adding code to ehci-hcd to perform the handover, removing code from ohci-hcd to turn off ports during root-hub reinit, and adding code to ohci-hcd to turn on ports during PCI controller resume. (Other bus glue resume methods for platforms supporting high-speed controllers would need a similar change, if any existed.)

* ohci: Rework bus glue integration to allow several at onceSylvain Munaut2007-02-071-20/+0
| | | | | | | | | | | | | | | | | The previous model had the module_init & module_exit function in the bus glue .c files themselves. That's a problem if several glues need to be selected at once and the driver is built has module. This case is quite common in embedded system where you want to handle both the integrated ohci controller and some extra controller on PCI.

* USB: Properly unregister reboot notifier in case of failure in ehci hcdAleksey Gorelov2006-09-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | If some problem occurs during ehci startup, for instance, request_irq fails, echi hcd driver tries it best to cleanup, but fails to unregister reboot notifier, which in turn leads to crash on reboot/poweroff. The following patch resolves this problem by not using reboot notifiers anymore, but instead making ehci/ohci driver get its own shutdown method. For PCI, it is done through pci glue, for everything else through platform driver glue. One downside: sa1111 does not use platform driver stuff, and does not have its own shutdown hook, so no 'shutdown' is called for it now. I'm not sure if it is really necessary on that platform, though.

* USB: OHCI avoids root hub timer pollingDavid Brownell2006-09-271-1/+4
| | | | | | | | | | | | | | This teaches OHCI to use the root hub status change (RHSC) IRQ, bypassing root hub timers most of the time and switching over to the "new" root hub polling scheme. It's complicated by the fact that implementations of OHCI trigger and ack that IRQ differently (the spec is vague there). Avoiding root hub timers helps mechanisms like "dynamic tick" leave the CPU in lowpower modes for longer intervals.

* [PATCH] USB: ohci uses driver model wakeup flagsDavid Brownell2006-03-201-2/+13
| | | | | | | | | | | | | | | | | | | This makes OHCI use the driver model wakeup control bits for its root hub (e.g. disable on amd756, because of chip erratum) and for the controller itself. It no longer uses the hcd glue bits with those roles, and depends on the previous patch making the root hub available earlier. Note that on most platforms (boot code properly setting the RWC bit) this gives a partial workaround for the way PCI isn't currently flagging devices that support PME# signals. (Because of odd PCI init sequencing on PPC.) That's because many OHCI controllers support "legacy PCI PM" ... without involving any PCI PM capability. USB wakeup from STR, if it works on your system, may still involve tweaking things by hand in /proc/acpi/wakeup.

* [PATCH] USB: Fix USB suspend/resume crasher (#2)Benjamin Herrenschmidt2005-11-291-2/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch closes the IRQ race and makes various other OHCI & EHCI code path safer vs. suspend/resume. I've been able to (finally !) successfully suspend and resume various Mac models, with or without USB mouse plugged, or plugging while asleep, or unplugging while asleep etc... all without a crash. Alan, please verify the UHCI bit I did, I only verified that it builds. It's very simple so I wouldn't expect any issue there. If you aren't confident, then just drop the hunks that change uhci-hcd.c I also made the patch a little bit more "safer" by making sure the store to the interrupt register that disables interrupts is not posted before I set the flag and drop the spinlock. Without this patch, you cannot reliably sleep/wakeup any recent Mac, and I suspect PCs have some more sneaky issues too (they don't frankly crash with machine checks because x86 tend to silently swallow PCI errors but that won't last afaik, at least PCI Express will blow up in those situations, but the USB code may still misbehave).

| | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it.

It renames the hub_suspend and hub_resume methods in struct usb_hcd to bus_suspend and bus_resume. These are more descriptive names, since the methods really do suspend or resume an entire USB bus, and less likely to be confused with the hub_suspend and hub_resume routines in hub.c. It also takes David's advice about removing the layer of bus glue, where those methods are called. And it implements a related change that David made to the other HCDs but forgot to put into dummy_hcd.
