I can't really work it out. It seems to be the kmem_cache_cache which has
a problem, but there have already been lots of caches created and even
this samw cache_node already used right beforehand with no problem.
Unless a CPU or node comes up or something right at this point or the
caller is scheduled onto a different CPU... oopses seem to all
have CPU#1, wheras boot CPU is probably #0 (these CPUs are node 0
and memory is only on node 1 and 2 where there are no CPUs if I read
correctly).
I still can't see the reason for the failure, but can you try this
patch please and show dmesg?

* [PATCH 2.6.31] ehca: Tolerate dynamic memory operations and huge pages
From: Hannes Hering @ 2009-06-09 13:59 UTC (permalink / raw)
To: rdreier; +Cc: alexs, linux-kernel, ewg, linuxppc-dev, raisch, ossrosch
This patch implements toleration of dynamic memory operations and 16 GB
gigantic pages. On module load the driver walks through available system
memory, checks for available memory ranges and then registers the kernel
internal memory region accordingly. The translation of address ranges is
implemented via a 3-level busmap.
Signed-off-by: Hannes Hering <hering2@de.ibm.com>
---
This patch is built and tested against infiniband.git. Please apply for 2.6.31.
Regards
Hannes

Hi
sorry for late responce. my e-mail reading speed is very slow ;-)
First, Could you please read past thread?
I think many topic of this mail are already discussed.

No.
Now, we talk about off-node allocation vs unnecessary file cache dropping.
IOW, off-node allocation vs disk access.
Then, the worth doesn't only depend on off-node distance, but also depend on
workload IO tendency and IO speed.
Fujitsu has 64 core ia64 HPC box, zone-reclaim sometimes made performance
degression although its box.
So, I don't think this problem is small vs large machine issue.
nor i7 issue.
high-speed P2P CPU integrated memory controller expose old issue.

hmmm..
I don't hope ignore AMD, I think it's common characterastic of P2P and
integrated memory controller machine.
Also, I don't hope detect CPU family or similar, because we need update
such code evey when Intel makes new cpu.
Can we detect P2P interconnect machine? I'm not sure.

hmhm.
I think the key-point of option 1 and 2 are proper hardware detecting way.
option 3 and 4 are more prefere idea to me. I like workload adapted heuristic.
but you already pointed out its hard, because page-allocator don't know
allocation purpose ;)

arch/ia64/include/asm/topology.h has
/*
* Distance above which we begin to use zone reclaim
*/
#define RECLAIM_DISTANCE 15
I don't think distance==15 is machine independent proper definition.
but there is long lived definition ;)

I was sort-of planning on coming up with an x86_64 arch specific function
for setting zone_reclaim_mode, but didn't like the direction things
were going.
Something to the effect of...

And then letting each arch define an arch_zone_reclaim_mode(). If other
values are needed in the determination, we would add parameters to
reflect this.
For ia64, add
static inline ia64_zone_reclaim_mode(int distance)
{
if (distance > 15)
return 1;
}
#define arch_zone_reclaim_mode(_d) ia64_zone_reclaim_mode(_d)
Then, inside x86_64_zone_reclaim_mode(), I could make it something like

In the end, I didn't think this fight was worth fighting given how ugly
this felt. Upon second thought, I am beginning to think it is not that
bad, but I also don't think it is that good either.

* [PATCH] mpc83xx/usb.c: fix usb mux setup for mpc834x
From: Peter Korsgaard @ 2009-06-09 11:43 UTC (permalink / raw)
To: galak, linuxppc-dev
usb0 and usb1 mux settings in the sicrl register were swapped (twice!)
in mpc834x_usb_cfg(), leading to various strange issues with fsl-ehci
and full speed devices.
The USB port config on mpc834x is done using 2 muxes: Port 0 is always
used for MPH port 0, and port 1 can either be used for MPH port 1 or DR
(unless DR uses TMDI phy or OTG, then it uses both ports) - See 8349 RM
figure 1-4..
mpc8349_usb_cfg() had this inverted for the DR, and it also had the bit
positions of the usb0 / usb1 mux settings swapped. It would basically
work if you specified port1 instead of port0 for the MPH controller (and
happened to use ULPI phys), which is what all the 834x dts have done,
even though that configuration is physically invalid.
Instead fix mpc8349_usb_cfg() and adjust the dts files to match reality.

To be honest, I'm more leaning towards a NACK than an ACK on this one. I
don't support enough NUMA machines to feel strongly enough about it but
unconditionally setting zone_reclaim_mode to 0 on x86-64 just because i7's
might be there seems ill-advised to me and will have other consequences for
existing more traditional x86-64 NUMA machines.

In any case, doing PAGE_KERNEL_NOCACHE for DMA memory is incorrect on
many architectures. So at this stage, there's no much option but ifdef I
suspect for now until this is fixed properly.
It does make sense to want to have some memory like that shared between
user space and DMA, though I don't know what the right approach that
works on all archs is at this stage. Worth asking the Alsa guys, I think
they have similar issues :-)
But doing double buffering might do the trick fine for now.
Cheers,
Ben.

Since i2c probing is hit and miss at best; Most MPCxxxx SPI busses get
the i2c bus topology out of the device tree file
(arch/powerpc/boot/dts/<board-name>.dts) and do not support probing.
If the i2c device you need is missing, then add a node to the .dts
file for the missing device (there are lots of examples of this in the
dts directory).

Hi all,
The sensors can't be detected on the built-in I2C interface on the Freescale's MPC processors on linux-2.6.29.
If it is not yet fixed, I think that it is forgotten to set the following values in the class.

I've partially missed that thread. Is the a bugzilla entry or

* [PATCH] powerpc/boot: cuboot: Fix up ethernet3 MAC address on MPC85xx
From: Nate Case @ 2009-06-08 22:17 UTC (permalink / raw)

You don't need this if you always return success.

I'd prefer we move this into __setup_cpu_e500v1/__setup_cpu_e500v2 so
its done for all processors regardless of platform.

Not only I don't think it's going to guarantee RT response (just improve
it), that's a pretty big hammer to work around what is a design bug in
your system in the first place :-)

No. It call the -flow- handler, which is a different thing (yes, the
terminology can be a bit confusing). The flow handler is configured
by the interrupt controller itself and will do whatever necessary
ack'ing, masking, EOI'ing etc... for a given PIC around the call to the
actual driver handler.

They do. You missed it.

Reading the IACK is what get_irq() does on OpenPIC.

Which is done by the flow handler.

You obviously missed both :-)

DMA status indicates that DMA transfer is still active according to
the controller. This one is really a platform/hardware specific issue.

The errata was only for the d-side. The patch is in the mainline

To put this clearer: on '5200 based systems, the driver (more specific:
the function inline_map_copy_to()) *must* know whether the hardware is
connected in 8-bit or 16-bit mode to the Local Plus Bus, as byte writes
(issued by memcpy_toio()) will fail for the latter setup (probably the
same applies for byte and word writes in 32-bit mode).
IMHO, this information should be passed using the device tree. The
"bank-width" seems to be an obvious choice for that.
Best, Albrecht.

The first patch was pushed back on because it didn't solve it for all the
architectures that use mkimage for various builds. I'd like to get back to
that, but haven't had time yet.

what about using the RT-Preempt Patch? i can see that it will convert Linux

i have check the function of do_IRQ: there is no ack called b 4 calling the
handler but actually it does the following:
1. it gets the irq number using :
irq = ppc_md.get_irq();
2. then it calls the handler :
if (irq != NO_IRQ && irq != NO_IRQ_IGNORE) {
generic_handle_irq(irq);
} else if (irq != NO_IRQ_IGNORE)
/* That's not SMP safe ... but who cares ? */
ppc_spurious_interrupts++;
i have checked the function of generic_handle_irq where it is defined
linux/irq.h & it calls the handler
so from the previous code the processor or the pic does not ack but they
call my ISR handler.
i have also read the specs of my OpenPIC & found that:
"the interrupt handler executing on the processor should then acknowledge
the interrupt by explicitly reading the IACK register.The PIC unit
interprets this read as an interrupt acknowledge (IACK) cycle; in response,
the PIC unit returns the vector associated with the
interrupt source to the interrupt handler routine."
"At the end of the interrupt the End Of Interrupt (EOI) register must be
set"
So the processor neither reads this iack register nor the handler set the
EOI register.
how is the interrupts works on my board? i dont know?
my linux version is 2.6.27.

The underlying map_ram-driver uses it once while erasing. The question remains
if this is really needed? And: Does this need to get solved before merging my
patches because changing the binding afterwards is hard? Or can they go
mainline nevertheless?

Hi,
we just tried to find differences for the timing with the oszi:
Here are to screenshots taken from the initial first few data bytes that are
communicated. At least at that time there does not seem to be any timing
issue.
2.6.26 using arch ppc and virtex-devices:
http://img145.imageshack.us/img145/9662/2626virtexdevices.jpg
2.6.29.4 using arch powerpc:
http://img145.imageshack.us/img145/9847/2629devtree.jpg
For explanation:
yellow = chan 1 = MOSI = trigger
green = chan 2 = chipselect not
blue = chan 3 = clock
red = chan 4 = MOSI
Looks like we're gonna have to switch to a logic analyzer
(with spi-mode sdcard analyzing support) as we cannot see any differences
in the short timeframe our oszi does measure, though checking the timing
does not look too promising.
We even configured the Xilinx-SPI core to go down to ~780 kHz just to be
safe,
did not help either.
Regards,
Lorenz
