This is patch as550 from Alan Stern. Apparently someone changed the SCSI core so that it no longer holds the host lock when doing a device or bus reset. usb-storage was updated at the time, but the change was done carelessly. Some of the code depends on that lock being held. This patch reintroduces the host lock where needed and tries to clarify the comments explaining why the lock is necessary. It also moves the code that clears the TIMED_OUT and ABORTING bitflags so that it executes as soon as the timed-out command has completed (and while the host lock is held). Signed-off-by:

This appears to help some folk, please merge. This patch relaxes reset timings. There are some reports that it helps make enumeration work better on some high speed devices. Signed-off-by:

This patch adds the product ID and vendor ID for a Nokia CA-42 USB cable to the list of devices handled by the pl2303 driver. The patch is against 2.6.13. Signed-off-by:

Now that it's in use on other boards, a bug in the original code needs fixing. There is no need for the PXA27x OHCI to set usb power during init, since the hub driver in usbcore handles that. Those platform-specific power control functions are also incorrect, and should therefore be removed. Add a check to clear the OTG pin hold bit until such times OTG is properly implemented.

Some OHCI implementations have differences in the way the NDP register (in roothub_a) reports the number of ports present. This patch allows the platform specific code to optionally supply the number of ports. The driver just reads the value at init (if not supplied) instead of reading it every time its needed (except for an AMD756 bug workaround). It also sets the value correctly for the ARM pxa27x architecture. Signed-Off-By:

Evidently there are some boards which care a lot about this, but as a rule it's been hard to notice. OHCI_INTR_RD wasn't always cleared in the ohci irq handler. On some systems this means certain remote wakeup scenarios could seem to hang (in an interrupt storm, RD never clearing). From: "William Morrow" <William.Morrow@amd.com> Signed-off-by:

Routine cases like handoff-to-companion shouldn't trigger diagnostics. This gets rid of some recently added log spamming. It's routine for hub_port_wait_reset() to return -ENOTCONN to indicate handoff from highspeed hubs to companions, so an error message is incorrect. Signed-off-by:

One change may improve some S1 or S3 resume cases, and the other seems mostly to explain some strange state "lsusb" would show. Two fixes: - On resume, don't think about resuming any unpowered port, or resetting any port with OWNER set to the OHCI/UHCI companion. This will make some S1 and S3 resume scenarios work better. - PORT_CSC was not being cleared correctly in ehci_hub_status_data. This was visible at least through current versions of "lsusb", and might have caused some other hub related strangeness. The fix addresses all three write-to-clear bits, using the same approach that UHCI happens to use: a mask of bits that are cleared in most writes to that port status register. Original patch seems to have been from from William.Morrow@amd.com and this version (from David) finishes the write-to-clear changes. Signed-off-by: -

This patch (as558) removes from the UHCI driver a kernel timer used for checking Full Speed Bandwidth Reclamation (FSBR). The checking can be done during normal root-hub polling; it doesn't need a separate timer. Signed-off-by:

Alan Stern authored
This patch (as549) introduces two small changes in the HCD glue layer. The first simply removes a redundant test. The second allows root-hub polling to continue for a single iteration after a host controller dies; this is needed for the patch that follows. Signed-off-by:

This is a driver for the USB touchpad which can be found on post-February 2005 Apple PowerBooks. This driver is derived from Johannes Berg's appletrackpad driver [1], but it has been improved in some areas: * appletouch is a full kernel driver, no userspace program is necessary * appletouch can be interfaced with the synaptics X11 driver[2], in order to have touchpad acceleration, scrolling, two/three finger tap, etc. This driver has been tested by the readers of the 'debian-powerpc' mailing list for a few weeks now and I believe it is now ready for inclusion into the mainline kernel. Credits go to Johannes Berg for reverse-engineering the touchpad protocol, Frank Arnold for further improvements, and Alex Harper for some additional information about the inner workings of the touchpad sensors.

here is a new and extended version of the sisusbvga (previously: sisusb) driver. The patch is against 2.6.13 and updates the driver to version 0.0.8. Additions include complete VGA/EGA text console support and a build-in display mode infrastructure for userland applications that don't know about the graphics internals. Fixes include some BE/LE issues and a get/put_dev bug in the previous version. Other changes include a change of the module name from "sisusb" to "sisusbvga". The previous one was too generic IMHO. Please note that the patch also affects the Makefile in drivers/video/console as the driver requires the VGA 8x16 font in case the text console part is selected. Heavily tested, as usual. Please apply. One thing though: I already prepared for removal of the "mode" field and the changed "name" field in the usb_class_driver structure. This will perhaps need some refinement depending on whether you/Linus merge the respective core changes before or after 2.6.14. Signed-off-by:

This is the same patch that went into i386 just before 2.6.13 came out. I still can't build 64-bit user apps, so I tested with program (see below) in 32-bit mode on 64-bit kernel: Before: $ fpsig handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10 handler: altstack is at 0x0804b000, ebp = 0x0804bc7c handler: si_signo = 8, si_errno = 0, si_code = 0 [unknown] handler: fpu cwd = 0xb40, fpu swd = 0xbaa0 handler: i387 unmasked precision exception, rounded up After: $ fpsig handler: nr = 8, si = 0x0804bc90, vuc = 0x0804bd10 handler: altstack is at 0x0804b000, ebp = 0x0804bc7c handler: si_signo = 8, si_errno = 0, si_code = 6 [inexact result] handler: fpu cwd = 0xb40, fpu swd = 0xbaa0 handler: i387 unmasked precision exception, rounded up Signed-off-by:

Being the foundation for reliable stack unwinding, this fixes CFI unwind annotations in many low-level x86_64 routines, plus a config option (available to all architectures, and also present in the previously sent patch adding such annotations to i386 code) to enable them separatly rather than only along with adding full debug information.
