• c9a50cc93   [PATCH] USB: hcd uses EXTRA_CFLAGS for -DDEBUG ... Browse Code »

  This modifies the HCD builds to automatically "-DDEBUG" if
  CONFIG_USB_DEBUG is selected. It's just a minor source code cleanup,
  guaranteeing consistency.

• 462aae65f   [USB]: Make early handoff a final fixup instead of a header one. ... Browse Code »

  At header fixup time, it is not yet legal to ioremap() PCI
  device registers, yet that is what this quirk code needs to
  do.

  The USB "handoff" code is an early PCI quirk to make sure we own the USB
  controller (as opposed to the BIOS/SMM). But if the controller isn't
  even enabled yet, don't try to access it.

• 478a3bab8   [PATCH] USB: Always do usb-handoff ... Browse Code »

  This revised patch (as586b) makes usb-handoff permanently true and no
  longer a kernel boot parameter. It also removes the piix3_usb quirk code;
  that was nothing more than an early version of the USB handoff code
  (written at a time when Intel's PIIX3 was about the only motherboard with
  USB support). And it adds identifiers for the three PCI USB controller
  classes to pci_ids.h.

• bb200f6ea   [PATCH] UHCI: unify BIOS handoff and driver reset code ... Browse Code »

  This patch (as574) updates the PCI BIOS usb-handoff code for UHCI
  controllers, making it work like the reset routines in uhci-hcd. This
  allows uhci-hcd to drop its own routines in favor of the new ones
  (code-sharing).

  Once the patch is merged we can turn the usb-handoff option on
  permanently, as far as UHCI is concerned. OHCI and EHCI may still have
  some issues.

• f2cb36c1d   [PATCH] update PCI early-handoff handling for OHCI ... Browse Code »

  The PCI "early usb handoff" quirk logic didn't work like "ohci-hcd" ...
  This patch makes it do so by:

  - Resetting the controller after kicking BIOS off, matching the
  normal "chip in hardware reset" startup mode;

  - Reporting any BIOS that borks this simple handoff; it's likely
  got a few other surprises for us too.

  - Ignoring that handoff on HPPA;

  The diagnostic string is mostly shared with EHCI, saving a few bytes.

• 7586269c0   [PATCH] USB: move handoff code ... Browse Code »

  This moves the PCI quirk handling for USB host controllers from the
  PCI directory to the USB directory. Follow-on patches will need to:

  (a) merge these copies with the originals in the HCD reset methods.
  they don't wholly agree, despite doing the very same thing; and

  (b) eventually change it so "usb-handoff" is the default, to help
  get more robust USB/BIOS/input/... interactions.
