[PATCH] usbcore: allow suspend/resume even if drivers don't support it

2005-12-21T22:46:35+00:00

This patch (as618) changes usbcore to prevent derailing the
suspend/resume sequence when a USB driver doesn't include support for
it.  This is a workaround rather than a true fix; the core needs to be
changed so that URB submissions from suspended drivers can be refused
and outstanding URBs cancelled.

[PATCH] USB: Fix USB suspend/resume crasher (#2)

2005-11-30T05:39:23+00:00

This patch closes the IRQ race and makes various other OHCI & EHCI code
path safer vs. suspend/resume.
I've been able to (finally !) successfully suspend and resume various
Mac models, with or without USB mouse plugged, or plugging while asleep,
or unplugging while asleep etc... all without a crash.

Alan, please verify the UHCI bit I did, I only verified that it builds.
It's very simple so I wouldn't expect any issue there. If you aren't
confident, then just drop the hunks that change uhci-hcd.c

I also made the patch a little bit more "safer" by making sure the store
to the interrupt register that disables interrupts is not posted before
I set the flag and drop the spinlock.

Without this patch, you cannot reliably sleep/wakeup any recent Mac, and
I suspect PCs have some more sneaky issues too (they don't frankly crash
with machine checks because x86 tend to silently swallow PCI errors but
that won't last afaik, at least PCI Express will blow up in those
situations, but the USB code may still misbehave).

[PATCH] USB: ohci, move ppc asic tweaks nearer pci

2005-11-24T07:04:28+00:00

This should fix a suspend/resume issues that appear with OHCI on some
PPC hardware.  The PCI layer should doesn't have the hooks needed for
such ASIC-specific hooks (in this case, software clock gating), so
this moves the code to do that into hcd-pci.c ... where it can be
done after the relevant PCI PM state transition (to/from D3).

[PATCH] USB: EHCI updates

2005-11-24T07:04:28+00:00

This fixes some bugs in EHCI suspend/resume that joined us over the past
few releases (as usbcore, PCI, pmcore, and other components evolved):

  - Removes suspend and resume recursion from the EHCI driver, getting
    rid of the USB_SUSPEND special casing.

  - Updates the wakeup mechanism to work again; there's a newish usbcore
    call it needs to use.

  - Provide simpler tests for "do we need to restart from scratch", to
    address another case where PCI Vaux was lost.  (In this case it was
    restoring a swsusp snapshot, but there could be others.)

Un-exports a symbol that was temporarily exported.

A notable change from previous version is that this doesn't move
the spinlock init, so there's still a resume/reinit path bug.

[PATCH] USB: move CONFIG_USB_DEBUG checks into the Makefile

2005-11-17T19:29:55+00:00

This lets us remove a lot of code in the drivers that were all checking
the same thing.  It also found some bugs in a few of the drivers, which
has been fixed up.
