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.

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:

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.

As noted by matz@suse.de The problem is, that on i386 the syscallN macro is defined like so: long __res; \ __asm__ volatile ("int $0x80" \ : "=a" (__res) \ : "0" (__NR_##name),"b" ((long)(arg1)),"c" ((long)(arg2)), \ "d" ((long)(arg3)),"S" ((long)(arg4)),"D" ((long)(arg5))); \ If one of the arguments (in the _llseek syscall it's the arg4) is a pointer which the syscall is expected to write to (to the memory pointed to by this ptr), then this side-effect is not captured in the asm. If anyone uses this macro to define it's own version of the syscall (sometimes necessary when not using glibc) and it's inlined, then GCC doesn't know that this asm write to "*dest", when called like so for instance: out = 1; llseek (fd, bla, blubb, &out, trara) use (out); Here nobody tells GCC that "out" actually is written to (just a pointer to it is passed to the asm). Hence GCC might (and in the above bug did) copy-propagate "1" into the second use of "out". The easiest solution would be to add a "memory" clobber to the definition of this syscall macro. As this is a syscall, it shouldn't inhibit too many optimizations. Signed-off-by: -
