* USB: Let some USB host controllers get IRQ flags from resourceMarc Zyngier2008-10-17
| | | | | | | | | | | | | | | | | | | | | | | [This version fixes a thinko in the r8a66597 driver] This patch let a few discrete USB host controllers drivers (isp116x-hcd, r8a66597-hcd and sl811-hcd) obtain IRQ flags from their IORESOURCE_IRQ resource if configured as such, much like it's been done for the smc91x driver. It spares people writing support for specific boards the burden to configure the interrupt controller independantly, and keeps all IRQ related information in a single resource. HCD that are integrally part of a SoC have been left aside, as there is probably no "wiring" options... Tested on an Xscale PXA-255 based platform with isp116x-hcd.

* Rename WARN() to WARNING() to clear the namespaceArjan van de Ven2008-07-25
| | | | | | | | | | | | | We want to use WARN() as a variant of WARN_ON(), however a few drivers are using WARN() internally. This patch renames these to WARNING() to avoid the namespace clash. A few cases were defining but not using the thing, for those cases I just deleted the definition.

* PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | This patch (as969) continues the ongoing changes to the way HCDs report URB statuses. The programming interface has been simplified by making usbcore responsible for clearing urb->hcpriv and for setting -EREMOTEIO status when an URB with the URB_SHORT_NOT_OK flag ends up as a short transfer. By moving the work out of the HCDs, this removes a fair amount of repeated code.

* USB: make HCDs responsible for managing endpoint queuesAlan Stern2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as954) implements a suggestion of David Brownell's. Now the host controller drivers are responsible for linking and unlinking URBs to/from their endpoint queues. This eliminates the possiblity of strange situations where usbcore thinks an URB is linked but the HCD thinks it isn't. It also means HCDs no longer have to check for URBs being dequeued before they were fully enqueued. In addition to the core changes, this requires changing every host controller driver and the root-hub URB handler. For the most part the required changes are fairly small; drivers have to call usb_hcd_link_urb_to_ep() in their urb_enqueue method, usb_hcd_check_unlink_urb() in their urb_dequeue method, and usb_hcd_unlink_urb_from_ep() before giving URBs back. A few HCDs make matters more complicated by the way they split up the flow of control. In addition some method interfaces get changed. The endpoint argument for urb_enqueue is now redundant so it is removed. The unlink status is required by usb_hcd_check_unlink_urb(), so it has been added to urb_dequeue.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

* USB: Dealias -110 code (more complete)Pete Zaitcev2006-09-27
| | | | | | | | | | | | | | | | | | | The purpose of this patch is to split off the case when a device does not reply on the lower level (which is reported by HC hardware), and a case when the device accepted the request, but does not reply at upper level. This redefinition allows to diagnose issues easier, without asking the user if the -110 happened "immediately". The usbmon splits such cases already thanks to its timestamp, but it's not always available. I adjusted all drivers which I found affected (by searching for "urb"). Out of tree drivers may suffer a little bit, but I do not expect much breakage. At worst they may print a few messages.

It also takes David's advice about removing the layer of bus glue, where those methods are called.

(The basic problem is that CONFIG_HOTPLUG is global, which is wrong since not all busses can hotplug even on hotplug-friendly systems...)

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
