[PATCH] UHCI: add missing memory barriers

This patch (as617) adds a couple of memory barriers that Ben H. forgot in
his recent suspend/resume fix.

[PATCH] USB: ehci fixups

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

Rename the EHCI "reset" routine so it better matches what it does (setup);
and move the one-time data structure setup earlier, before doing anything
that implicitly relies on it having been completed already.

[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 split init/reinit logic for resume

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

Moving the PCI-specific parts of the EHCI driver into their own file
created a few issues ... notably on resume paths which (like swsusp)
require re-initializing the controller.  This patch:

 - Splits the EHCI startup code into run-once HCD setup code and
   separate "init the hardware" reinit code.  (That reinit code is
   a superset of the "early usb handoff" code.)

 - Then it makes the PCI init code run both, and the resume code only
   run the reinit code.

 - It also removes needless pci wrappers around EHCI start/stop methods.

 - Removes a byteswap issue that would be seen on big-endian hardware.

The HCD glue still doesn't actually provide a good way to do all this
run-one init stuff in one place though.

[PATCH] USB: EHCI updates mostly whitespace cleanups

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

This cleans up the recent updates to EHCI PCI support:

  - Gets rid of checks for "is this a PCI device", they're no
    longer needed since this is now all PCI-only code.

  - Reduce log spamming:  MWI is only interesting in the atypical
    case that it can actually be used.

  - Whitespace cleanup, as appropriate for a new file with no
    other pending patches.

So other than that minor logging change, no functional updates.

[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.
