2011-05-20sanitize <linux/prefetch.h> usageLinus Torvalds
Commit e66eed651fd1 ("list: remove prefetching from regular list iterators") removed the include of prefetch.h from list.h, which uncovered several cases that had apparently relied on that rather obscure header file dependency. So this fixes things up a bit, using grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]') grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]') to guide us in finding files that either need <linux/prefetch.h> inclusion, or have it despite not needing it. There are more of them around (mostly network drivers), but this gets many core ones.

2011-03-13USB 3.0 Hub ChangesJohn Youn
Update the USB core to deal with USB 3.0 hubs. These hubs have a slightly different hub descriptor than USB 2.0 hubs, with a fixed (rather than variable length) size. Change the USB core's hub descriptor to have a union for the last fields that differ. Change the host controller drivers that access those last fields (DeviceRemovable and PortPowerCtrlMask) to use the union. Translate the new version of the hub port status field into the old version that khubd understands. (Note: we need to fix it to translate the roothub's port status once we stop converting it to USB 2.0 hub status internally.) Add new code to handle link state change status. Send out new control messages that are needed for USB 3.0 hubs, like Set Hub Depth. This patch is a modified version of the original patch submitted by John Youn. It's updated to reflect the removal of the "bitmap" #define, and change the hub descriptor accesses of a couple new host controller drivers.

2011-03-13USB: Remove bitmap #define from hcd.hSarah Sharp
Using a #define to redefine a common variable name is a bad thing, especially when the #define is in a header. include/linux/usb/hcd.h redefined bitmap to DeviceRemovable to avoid typing a long field in the hub descriptor. This has unintended side effects for files like drivers/usb/core/devio.c that include that file, since another header included after hcd.h has different variables named bitmap. Remove the bitmap #define and replace instances of it in the host controller code. Cleanup the spaces around function calls and square brackets while we're at it.

In drivers/usb/host/sl811-hcd.c::sl811h_urb_enqueue(), memory is allocated with kzalloc() and assigned to 'ep'. If we leave via the 'fail' label due to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope without having been assigned to anything, so we'll leak the memory we allocated.

2010-05-20USB: straighten out port feature vs. port status usageAlan Stern
This patch (as1349b) clears up the confusion in many USB host controller drivers between port features and port statuses. In mosty cases it's true that the status bit is in the position given by the corresponding feature value, but that's not always true and it's not guaranteed in the USB spec. There's no functional change, just replacing expressions of the form (1 << USB_PORT_FEAT_x) with USB_PORT_STAT_x, which has the same value.

(There is a PORT_LOWSPEED feature, but the spec doesn't mention it except to say that host software should never use it.) The speed indicators are port statuses, not port features.

2008-10-17USB: Let some USB host controllers get IRQ flags from resourceMarc Zyngier
[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.

2008-02-23PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki
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.

2007-10-12USB: make HCDs responsible for managing endpoint queuesAlan Stern
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.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.

2006-09-27USB: Dealias -110 code (more complete)Pete Zaitcev
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.

This moves header files for controller-specific platform data from <linux/usb_XXX.h> to <linux/usb/XXX.h> to start reducing some clutter. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-03-20[PATCH] USB core and HCDs: don't put_device while atomicAlan Stern
This patch (as640) removes several put_device and the corresponding get_device calls from the USB core and HCDs. Some of the puts were done in atomic contexts, and none of them are needed since the core now guarantees that every endpoint will be disabled and every URB completed before a USB device is released.

2006-01-04[PATCH] USB: central handling for host controllers that were reset during ↵Alan Stern
suspend/resume This patch (as515b) adds a routine to usbcore to simplify handling of host controllers that lost power or were reset during suspend/resume. The new core routine marks all the child devices of the root hub as NOTATTACHED and tells khubd to disconnect the device structures as soon as possible.

2006-01-04[PATCH] USB: hcd uses EXTRA_CFLAGS for -DDEBUGDavid Brownell
This modifies the HCD builds to automatically "-DDEBUG" if CONFIG_USB_DEBUG is selected. It's just a minor source code cleanup, guaranteeing consistency. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-04[PATCH] USB: wakeup flag updates (1/3) sl811-hcdDavid Brownell
This makes the SL811 HCD use the driver model wakeup flags for its controller, not the flags in the HCD glue (which will be removed).

2005-10-28[PATCH] USB: Rename hcd->hub_suspend to hcd->bus_suspendAlan Stern
This patch (as580) is perhaps the only result from the long discussion I had with David about his changes to the root-hub suspend/resume code. 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.

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.
