Hi Alistair,
I've just rebased some CAPI patches on top of 4.2-rc4 and I'm getting a
new WARN relating to IRQs in EEH, which I believe is related to your
patch 79231448c929 ("powernv/eeh: Update the EEH code to use the opal
irq domain").
This is what I see after injecting a PHB fence on a CAPI ca

Hi, thanks for considering m
Hello,
This patch series reworks endpoint matching and claiming mechanism in
epautoconf. From v2 there are couple of new patches adding 'ep_match'
to usb_gadget_ops and removing chip-specific quirk handling from generic
code of autoconfig.
I'm not sure if this patch set isn't too long, as it has
So far it was necessary for usb functions to set ep->driver_data in
endpoint obtained from autoconfig to non-null value, to indicate that
endpoint is claimed by function (in autoconfig it was checked if endpoint
has set this field to non-null value, and if it has, it was assumed that
it is claimed)
Introduce struct usb_ep_caps which contains information about capabilities
of usb endpoints - supported transfer types and directions. This structure
should be filled by UDC driver for each of its endpoints, and will be
used in epautoconf in new ep matching mechanism which will replace ugly
guessin
Add macros useful while initializing array of endpoint capabilities
structures. These macros makes structure initialization more compact
to decrease number of code lines and increase readability of code.

Introduce endpoint matching mechanism basing on endpoint capabilities
flags. We check if endpoint supports transfer type and direction requested
in ep descriptor. Since we have this new endpoint matching mechanism
there is no need to have old code guessing endpoint capabilities basing
on its name,
The same effect can be achieved by using capabilities flags, so now we can
get rid of handling of hardware specific limitations in generic code.

This patch begs the question: this passes everything? (I was reminded
about syscall_restart while reading the patches. If everything passes,
it looks like powerpc exposes s

That is a very old kernel. If you're using that old kernel be
There are powerpc generic version and x86 local version.
Move the powerpc version to setup-bus.c, and kill x86 local version.
Also kill dummy version in microblaze.

For device resource PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource, so set
IORESOUCE_MEM_64 for 64bit resource during of device resource flags
parsing.
Link: https://bugzilla.kernel.org/show_bug.cgi?id=96261
Link: https://bugzilla.kernel.o
so we can cover !flags and IORESOURCE_DISABLED both.

Hi Daniel,
I see the problem - pnv_eeh_next_error() re-enables the interrupt but it gets
called from a loop if there are more outstanding events to process. The most
obvious solution would be to do this check before enabling interrupts:
if (ret == EEH_NEXT_ERR_NONE && eeh_enabled())

Hi Alistair and Gavin,
The patch from Alistair fixes my issue. Thanks heaps!
Alistair, are you right to post that formally?
