You could add show_state to check_hung_task
It worked for me while solving some (application) task hangups.

Will have a look at that too, thanks.
Meanwhile i have tried to turn on various LOCK debug and
that results in an unbootable kernel.
Somewhere the dev. tree. gets mangled and it happens when
DEBUG_LOCK_ALLOC is set.
Don't know why and I must move on.
Someone else might want to try if DEBUG_LOCK_ALLOC works
on embedded ppc boards, especially 83xx.

* [PATCH V2 0/3][RFC] Add Support for Virtual Processor Home Node (VPHN)
From: Jesse Larrew @ 2010-11-09 23:24 UTC (permalink / raw)
To: linuxppc-dev; +Cc: markn, pmac, tbreeds, lkessler, Jesse Larrew, mjwolf
From: Jesse Larrew <jlarrew@linux.vnet.ibm.com>
The SPLPAR option allows the platform to dispatch virtual processors on
physical processors that, due to the variable nature of work loads, are
temporarily free, thus improving the utilization of computing resources.
However, SPLPAR implies inconsistent mapping of virtual to physical
processors, thus defeating resource allocation software that attempts to
optimize performance on platforms that implement the NUMA option.
To bridge the gap between these two options, the VPHN option maintains a
substantially consistent mapping of a given virtual processor to a physical
processor or set of processors within a given associativity domain. When
allocating computing resources, the kernel can take advantage of this
statistically consistent mapping to improve processing performance.
VPHN mappings are substantially consistent but not static. For any given
dispatch cycle, a best effort is made by the hypervisor to dispatch the
virtual processor on a physical processor within a targeted associativity
domain (the virtual processor's home node). However, if processing capacity
within the home node is not available, some other physical processor is
assigned to meet the processing capacity entitlement. From time to time,
to optimize the total platform performance, it may be necessary for the
platform to change the home node of a given virtual processor.
The Virtual Processor Home Node feature addresses this by adding the
H_HOME_NODE_ASSOCIATIVITY hcall to retrieve the current associativity
domain information directly from the hypervisor for a given virtual
processor's home node. It also exposes a set of associativity change
counters in the Virtual Processor Area (VPA) of each processor to indicate
when associativity changes occur.
This patch set sets a timer during boot that will periodically poll the
associativity change counters. When a change in associativity is detected,
it retrieves the new associativity domain information via the
H_HOME_NODE_ASSOCIATIVITY hcall and updates the NUMA node maps and sysfs
entries accordingly. The polling mechanism is also tied into the
ibm,suspend-me rtas call to stop/restart polling before/after a suspend,
hibernate, migrate, or checkpoint restart operation.
This patch set applies to v2.6.36 and includes the following:
[PATCH 1/3] powerpc: Add VPHN firmware feature
[PATCH 2/3] powerpc: Poll VPA for topology changes and update NUMA maps
[PATCH 3/3] powerpc: Disable VPHN polling during a suspend operation
Changes since V1:
* topology.h: Removed unrelated comments added in V1.
* numa.c: Renamed init_topology_update() to start_topology_update() and
removed the __init attribute.
* topology.h: Fixed the inlined definitions of start_topology_update()
and stop_topology_update().
* rtas.c: Removed the "generic" pre_suspend_work() and
post_suspend_work() functions. Proper notifier chains will be added
in a future patch.

associativity is detected, it retrieves the new associativity domain
information via the H_HOME_NODE_ASSOCIATIVITY hcall and updates the
NUMA node maps and sysfs entries accordingly. Note that since the
ibm,associativity device tree property does not exist on configurations
with both NUMA and SPLPAR enabled, no device tree updates are necessary.

I never got round to replying to you about my comments did I. This looks
good, in particular you're right about the error path in
__rtas_suspend_last_cpu(), I was getting muddled trying to read the code
while mentally adding the diff.

* [PATCH] ppc44x:PHY fixup for USB on canyonlands board
From: Rupjyoti Sarmah @ 2010-11-10 11:37 UTC (permalink / raw)
To: linuxppc-dev, linux-kernel; +Cc: rsarmah
This fix is a reset for USB PHY that requires some amount of time for power to be stable on Canyonlands.

Is this just for canyonlands? If so, it's probably better off in a
caynonlands specific file, or a function that gets called in the common
platform file if the model matches canyonlands. It seems a bit overkill
to introduce an entire new file and Kconfig option for this.

Normally we don't leave a space in compatible properties.

We already have "ibm,ppc4xx-gpio" as an established compatible field for
4xx GPIO. As far as I know, this is not a different kind of GPIO
controller than what is found on the other boards, so we should stick
with the existing property.

If this fails, but the bcsr search works, what happens? Possibly
nothing, but I wonder if the search for both nodes should be done before
actually touching the hardware.

With this being an arch_initcall, it will get called for every kind of
platform in a multi-board kernel. Another reason to only call it from a
board specific probe function if it really is canyonlands specific.

Right. Time to take canyonlands out of ppc4xx_simple and have its own
board file again. Do the fixups there.

We want to have a file that will have fixup codes for all the ppc44x
specific boards. Within this ppc44x_fixup.c file we would like to place
any fixup code that
might come later for any of the ppc44x based boards. Although I released
it only with Canyonlands code, it would be ppc44x specific file.
Do let me know if that is ok.

Rup

This node should be moved to the EBC section. It would look something like
this then (note the reg property change here):
CPLD: cpld@2,0 {
...
reg = <2 0x0 0x9>;
};

No. You should have a file per board that needs fixup. Take them out of
ppc4xx_simple.c and create a board file.

After much soul searching I've finally got it to work!
For the benefit of anyone else...
- The lowest address of the dma descriptor contains the 'command' bits.
- Set 'Next descriptor valid' with a zero pointer to get the chain to
complete.
- Set the dma descriptor status word to zero (might just need 'done'
clear).
- Set the 'snoop for CSB' bit in the descriptor command (errata).
My big problem was that I'd set the descriptor status to 0xdeadbeef in
order to detect writes :-(
I also used the st_le32() and ld_le32() defines from
arch/powerpc/include/asm/swab.h with explicit iosync() requests
rather than the out_le32() and in_le32() from io.h.
The latter (especially in_le32()) contain unwanted slow instructions.
Getting the correct swab.h included was a problem in itself!

* Can't boot benh/powerpc.git kernel

I got Ben's linux/kernel/git/benh/powerpc.git source and built it
(.config file attached*). It hangs on boot. When I boot it with
loglevel=8, its last words are:
...
Security Framework initialized
SELinux: Disabled at boot.
Dentry cache hash table entries: 262144 (order: 5, 2097152 bytes)
Inode-cache hash table entries: 131072 (order: 4, 1048576 bytes)
Mount-cache hash table entries: 4096
Initializing cgroup subsys ns
Initializing cgroup subsys cpuacct
Initializing cgroup subsys memory
Initializing cgroup subsys devices
Initializing cgroup subsys freezer
irq: irq 2 on host null mapped to virtual irq 16
... and then it hangs.
The whole console log is attached.
Any suggestions?
This is on a Power 5 system -- model = IBM,9111-520.
*I earlier tried booting it with the following options enabled, with the
same result before and after I backed them off.
CONFIG_PREEMPT
CONFIG_DEBUG_PREEMPT
CONFIG_DEBUG_SLAB
CONFIG_DEBUG_PAGEALLOC
CONFIG_DEBUG_MUTEXES
CONFIG_DEBUG_SPINLOCK
CONFIG_DEBUG_SPINLOCK_SLEEP
Thanks.

First, please try with Linus upstream. The "master" branch in my git
tree is quite stale, and my next and merge branch are too at the moment
as I'm still travelling. All our current stuff was merged during the
last merge window so there's nothing "new" for you to pickup in my tree
at the moment :-)
If the problem still occurs, I'll have a look next week.
Cheers,
Ben.

Ben,
I think this is correct, but haven't really looked at all the code.

This implementation breaks an intended use of
fsl_rio_mcheck_exception():=20
1. for e500 it does not check the return value of the rio handler and
crashes the system even after RIO Mchk was serviced. Looks like e500mc
version handles it better but I have no HW to test it.
2. the RIO Mchk is expected to be handled quietly but here it has many
printk's. May be it is better to call the fsl_rio_mcheck_exception()
handler in very beginning and simply exit if it returns 1.
