2009-01-07USB: announce new devices earlierAlan Stern
This patch (as1166) changes usb_new_device(). Now new devices will be announced in the log _prior_ to being registered; this way the "new device" lines will appear before all the output from driver probing, which seems much more logical. Also, the patch adds a call to usb_stop_pm() to the failure pathway, so that the parent's count of unsuspended children will remain correct if registration fails. In order for this to work properly, the code to increment that count has to be moved forward, before the first point where a failure can occur.

2009-01-07USB: Allow usbmon as a module even if usbcore is builtinPete Zaitcev
usbmon can only be built as a module if usbcore is a module too. Trivial changes to the relevant Kconfig and Makefile (and a few trivial changes elsewhere) allow usbmon to be built as a module even if usbcore is builtin. This is verified to work in all 9 permutations (3 correctly prohibited by Kconfig, 6 build a suitable result).

2009-01-07USB: Introduce usb_queue_reset() to do resets from atomic contextsInaky Perez-Gonzalez
This patch introduces a new call to be able to do a USB reset from an atomic contect. This is quite helpful in USB callbacks to handle errors (when the only thing that can be done is to do a device reset). It is done queuing a work struct that will do the actual reset. The struct is "attached" to an interface so pending requests from an interface are removed when said interface is unbound from the driver. The call flow then becomes: usb_queue_reset_device() __usb_queue_reset_device() [workqueue] usb_reset_device() usb_probe_interface() usb_cancel_queue_reset() [error path] usb_unbind_interface() usb_cancel_queue_reset() usb_driver_release_interface() usb_cancel_queue_reset() Note usb_cancel_queue_reset() needs smarts to try not to unqueue when it is actually being executed. This happens when we run the reset from the workqueue: usb_reset_device() is called and on interface unbind time, usb_cancel_queue_reset() would be called. That would deadlock on cancel_work_sync(). To avoid that, we set (before running usb_reset_device()) usb_intf->reset_running and clear it inmediately after returning. Patch is against 2.6.28-rc2 and depends on http://marc.info/?l=linux-usb&m=122581634925308&w=2 (as submitted by Alan Stern).

2009-01-07USB: add asynchronous autosuspend/autoresume supportAlan Stern

2009-01-07USB: usb-storage: add "quirks=" module parameterAlan Stern
This patch (as1163b) adds a "quirks=" module parameter to usb-storage. This will allow people to make short-term changes to their unusual_devs list without rebuilding the entire driver. Testing will become much easier, and less-sophisticated users will be able to access their buggy devices after a simple config-file change instead of having to wait for a new kernel release. The patch also adds a documentation entry for usb-storage's "delay_use" parameter, which has been around for years but but was never listed among the kernel parameters.

2009-01-07USB: powerpc: Workaround for the PPC440EPX USBH_23 errata [take 3]Vitaly Bordug
A published errata for ppc440epx states, that when running Linux with both EHCI and OHCI modules loaded, the EHCI module experiences a fatal error when a high-speed device is connected to the USB2.0, and functions normally if OHCI module is not loaded. There used to be recommendation to use only hi-speed or full-speed devices with specific conditions, when respective module was unloaded. Later, it was observed that ohci suspend is enough to keep things going, and it was turned into workaround, as explained below. Quote from original descriprion: The 440EPx USB 2.0 Host controller is an EHCI compliant controller. In USB 2.0 Host controllers, each EHCI controller has one or more companion controllers, which may be OHCI or UHCI. An USB 2.0 Host controller will contain one or more ports. For each port, only one of the controllers is connected at any one time. In the 440EPx, there is only one OHCI companion controller, and only one USB 2.0 Host port. All ports on an USB 2.0 controller default to the companion controller. If you load only an ohci driver, it will have control of the ports and any deviceplugged in will operate, although high speed devices will be forced to operate at full speed. When an ehci driver is loaded, it explicitly takes control of the ports. If there is a device connected, and / or every time there is a new device connected, the ehci driver determines if the device is high speed or not. If it is high speed, the driver retains control of the port. If it is not, the driver explicitly gives the companion controller control of the port. The is a software workaround that uses Initial version of the software workaround was posted to linux-usb-devel: http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg54019.html and later available from amcc.com: http://www.amcc.com/Embedded/Downloads/download.html?cat=1&family=15&ins=2 The patch below is generally based on the latter, but reworked to powerpc/of_device USB drivers, and uses a few devicetree inquiries to get rid of (some) hardcoded defines.

2009-01-07USB: change interface to usb_lock_device_for_reset()Alan Stern
This patch (as1161) changes the interface to usb_lock_device_for_reset(). The existing interface is apparently not very clear, judging from the fact that several of its callers don't use it correctly. The new interface always returns 0 for success and it always requires the caller to unlock the device afterward. The new routine will not return immediately if it is called while the driver's probe method is running. Instead it will wait until the probe is over and the device has been unlocked. This shouldn't cause any problems; I don't know of any cases where drivers call usb_lock_device_for_reset() during probe.

2009-01-07USB: EHCI pci-quirks.c: don't wait so long for BIOS handoffSteven Noonan
Instead of waiting a painful 5000ms, quirk_usb_disable_ehci() now does a 1000ms loop to wait for the BIOS to acknowledge the handoff. The five second delay is really quite irritating to have to deal with every boot up, and I very seriously doubt any non-broken bios takes more than a second to do the actual handoff.

2009-01-07async: don't do the initcall stuff post bootArjan van de Ven
while tracking the asynchronous calls during boot using the initcall_debug convention is useful, doing it once the kernel is done is actually bad now that we use asynchronous operations post boot as well... Signed-off-by: Arjan van de Ven <arjan@linux.intel.com>
2009-01-07bootchart: improve output based on Dave Jones' feedbackArjan van de Ven
Dave Jones, in his blog, had some feedback about the bootchart script: Primarily his complaint was that shorter delays weren't visualized. The reason for that was that too small delays will have their labels mixed up in the graph in an unreadable mess. This patch has a fix for this; for one, it makes the output wider, so more will fit. The second part is that smaller delays are now shown with a much smaller font for the label; while this isn't per se readable at a 1:1 zoom, at least you can zoom in with most SVG viewing applications and see what it is you are looking at.

2009-01-07async: make the final inode deletion an asynchronous eventArjan van de Ven

2009-01-07fastboot: Make libata initialization even more asyncArjan van de Ven
As suggested by Linus: Don't do the libata init in 2 separate steps with a global sync inbetween, but do it as one async step, with a local sync before registering the device. This cuts the boottime on my machine with 2 sata controllers down significantly, and it seems to work. Would be nice if the libata folks take a good look at this patch though..

2009-01-07fastboot: make the libata port scan asynchronousArjan van de Ven
This patch makes the libata port scanning asynchronous (per device). There is a synchronization point before doing the actual disk scan so that device ordering is not affected. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com>
2009-01-07fastboot: make scsi probes asynchronousArjan van de Ven
This patch makes part of the scsi probe (which is mostly device spin up and the partition scan) asynchronous. Only the part that runs after getting the device number allocated is asynchronous, ensuring that device numbering remains stable. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com>
2009-01-07async: Asynchronous function calls to speed up kernel bootArjan van de Ven
Right now, most of the kernel boot is strictly synchronous, such that various hardware delays are done sequentially. In order to make the kernel boot faster, this patch introduces infrastructure to allow doing some of the initialization steps asynchronously, which will hide significant portions of the hardware delays in practice. In order to not change device order and other similar observables, this patch does NOT do full parallel initialization. Rather, it operates more in the way an out of order CPU does; the work may be done out of order and asynchronous, but the observable effects (instruction retiring for the CPU) are still done in the original sequence.

2009-01-07hwmon: Check for ACPI resource conflictsJean Delvare
Check for ACPI resource conflicts in hwmon drivers. I've included all Super-I/O and PCI drivers. I've voluntarily left out: * Vendor-specific drivers: if they conflicted on any system, this would pretty much mean that they conflict on all systems, and we would know by now. * Legacy ISA drivers (lm78 and w83781d): they only support chips found on old designs were ACPI either wasn't supported or didn't deal with thermal management. * Drivers accessing the I/O resources indirectly (e.g. through SMBus): the checks are already done where they belong, i.e. in the bus drivers.
