* [PATCH] Globally s/struct irq_host/struct irq_domain/
From: Jon Loeliger @ 2011-01-12 13:53 UTC (permalink / raw)
To: linuxppc-dev, devicetree-discuss
From: Jon Loeliger <jdl@jdl.com>
Just rename the irq_host structure as irq_domain to lessen the
confusion around the word "host". Updated a few comments and
error messages to use "irq_domain" when refering to the structure.
Suggested by Ben Herrenschmidt on the device-tree mailing list.

* [PATCH 2/2] powerpc: Enable 64kB pages and 1024 threads in pseries config
From: Anton Blanchard @ 2011-01-12 12:14 UTC (permalink / raw)
To: benh; +Cc: linuxppc-dev
In-Reply-To: <20110112231243.71c71291@kryten>
- Enable 64kB pages so it gets some regular testing.
- The largest POWER7 has 1024 threads so bump NR_CPUS it to match.

* [PATCH 9/9] powerpc: machine_check_generic is wrong on 64bit
From: Anton Blanchard @ 2011-01-12 5:52 UTC (permalink / raw)
To: benh, paulus; +Cc: linuxppc-dev
In-Reply-To: <20110112164318.753a435b@kryten>
Decoding machine checks is CPU specific and so machine_check_generic doesn't
do the right thing on 64bit chips. Luckily we never call into this code
because we call ppc_md.machine_check_exception instead if available.
Since we check cur_cpu_spec->machine_check before calling it, we may as
well remove machine_check_generic from 64bit archs.

* [PATCH 7/9] powerpc: Fix corruption when grabbing FWNMI data
From: Anton Blanchard @ 2011-01-12 5:50 UTC (permalink / raw)
To: benh, paulus; +Cc: linuxppc-dev
In-Reply-To: <20110112164318.753a435b@kryten>
The FWNMI code uses a global buffer without any locks to read the RTAS error
information. If two CPUs take a machine check at once then we will corrupt
this buffer.
Since most FWNMI rtas messages are not of the extended type, we can create a
64bit percpu buffer and use it where possible. If we do receive an extended
RTAS log then we fall back to the old behaviour of using the global buffer.

Rework pseries machine check handler:
- If MSR_RI isn't set, we cannot recover even if the machine check was fully
recovered
- Rename nonfatal to recovered
- Handle RTAS_DISP_LIMITED_RECOVERY
- Use BUS_MCEERR_AR instead of BUS_ADRERR
- Don't check all the RTAS error log fields when receiving a synchronous
machine check. Recent versions of the pseries firmware do not fill them
in during a machine check and instead send a follow up error log with
the detailed information. If we see a synchronous machine check, and we
came from userspace then kill the task.

If a machine check comes from userspace we send a SIGBUS to the task and
fail to printk anything.
If we are taking machine checks due to bad hardware we want to know about
it right away. Furthermore if we don't complain loudly then it will look
a lot like a bug in the userspace application, potentially causing a lot
of confusion.

* [PATCH 3/9] powerpc: Never halt RTAS error logging after receiving an unrecoverable machine check
From: Anton Blanchard @ 2011-01-12 5:46 UTC (permalink / raw)
To: benh, paulus; +Cc: linuxppc-dev
In-Reply-To: <20110112164318.753a435b@kryten>
Newer versions of the System p firwmare send a partial RTAS error log in the
machine check handler with a more detailed response appearing sometime later
via check event.
This means at machine check time we do not have enough information to
ascertain exactly what went on. Furthermore, I have found the RTAS error
logs in the machine check handler contain no useful information, so halting on
them makes little sense. If we want to halt it would make more sense to do
it following the error log received sometime later via check event.
In light of this, never halt the error log in the pseries machine
check handler.

In-Reply-To: <20110112164318.753a435b@kryten>
We should never force MSR_RI on. If we take a machine check with MSR_RI off
then we have no chance of recovering safely.

From: Benjamin Herrenschmidt @ 2011-01-12 0:16 UTC (permalink / raw)
To: Linus Torvalds; +Cc: linuxppc-dev list, Andrew Morton, Linux Kernel list
Hi Linus !
Here's the powerpc bunch for this merge window. Small this time, looks
like Kumar was too busy with holidays to send me anything from freescale
this time around.
There's some rework & cleanup of our nvram code, some support for the
POWER7+ processors, various iommu cleanups, etc... in terms of features,
we can note the support for some of IBM System P energy management and
VPHN feature which improves NUMA topology informations under our
hypervisor.

OK thank you for this precision. If you remember what version it was, we can
also diff it against mainline and see if we spot any relevant changes that
we need to take care of.
> Would be great if Scott could give them a spin on 8xx with current 2.4.
Indeed, that would be great. My goal really is that 2.4 users can upgrade
without wondering about any risk of regression. I appreciate a lot your
fixes, they mean some people might see that some issues have suddenly
disappeared. But it's important to stay on the non-reg side as much as
possible.

Wouldn't this patch be a good candidate for the stable kernel series?

I tested these on real 8xx HW but I used an older 2.4 linux as we haven't
moved forward on 2.4 for quite some time.
The affected files were almost identical though. Would be great if
Scott could give them a spin on 8xx with current 2.4.

Thank you very much for taking care of this, that's very much appreciated.
I'll look at this ASAP. Just a quick question in order to be certain, did
you have the opportunity to test all of these changes on real hardware ?

Right so instead of a 1:1 mapping you have a N:1 mapping. We support
both forms, tho it would have been nice if the fsl PCI code had properly
reconfigured the controller based on the DT.

Yes, definitely try different controllers. Also check your voltages just
in case....
Other things you can do is double check the settings of things like max
read request size, max payload size etc... in the PCIe config space of
the device and the bridge.

Ben.
