Hmm, odd.
Can you check how it's aligned without your change? ie. in the original
binary, is it 4 byte aligned?
When you make the change, is the only thing that changes in the binary
the alignedness of dtstruct, or does it cause other things to move
around?
I don't think an unaligned dt blob should have any effect on the kernel,
ie. it should copy it in fine, but I'd have to look at the code.

LTT?

Do you have CONFIG_PREEMPT set? The oops output seems to think so. Also,
seeing the LTT makes me wonder if you have added custom patches to your kernel?
Do you have a simple testcase that could be run to recreate this? If so,
could you provide it somewhere and perhaps your .config?

Actually, it just skips it as the function to use as the reference point.
It should still record the mcount for that function. Now we may have an
issues if all functions in a section start with .L

That said, I still think it makes sense to share this with the idle
routine, we can make some callbacks unsuitable for hot-unplug just fine.

Well, my main objection was that is was a single raw function pointer
without any management layer around it.
We have the exact same mess with the idle routine - and that has bitten
us in the past.

Yes,
You are right. CONFIG_PREEMPT is enabled in the kernel config.
Attached is the config.

Under certain circumstances, the newly loaded flush data will replace
previous flush data rather than the actual data you're trying to displace
-- especially if some of the "crap" is already in the cache, or if there
were some empty cache lines at the start of the process. It's not a true
LRU.
If you read 52K, and then dcbf that same 52K, with interrupts disabled
(they can disturb the PLRU), you should be OK. It doesn't even need to
be dedicated junk, any memory will work.

* need help getting SPI controller working on 405EX
From: Nathan French @ 2009-08-06 16:08 UTC (permalink / raw)
To: linuxppc-dev
Hi, I am trying to add support for the 405EX's SPI controller on a Kilauea board. I've added the below to the device tree (under plb/opb/):
[nfrench@nfrench-laptop linux-2.6-denx]$ diff -C2 arch/powerpc/boot/dts/kilauea.dts spi.dts

+ compatible = "ibm,spi-405ex", "ibm,spi";

+ interrupts = <8 4>;
+ interrupt-parent = <&UIC0>;
+ mode = "cpu";
+ };
RGMII0: emac-rgmii@ef600b00 {
I've also compiled my kernel with the following enabled:
CONFIG_SPI=y
CONFIG_SPI_MASTER=y
CONFIG_SPI_SPIDEV=y
I see this make it into the device tree after boot:
[root@10.2.3.28 /]$ find /proc/device-tree/ | grep spi
/proc/device-tree/plb/opb/spi@ef600600
/proc/device-tree/plb/opb/spi@ef600600/name
/proc/device-tree/plb/opb/spi@ef600600/mode
/proc/device-tree/plb/opb/spi@ef600600/interrupt-parent
/proc/device-tree/plb/opb/spi@ef600600/interrupts
/proc/device-tree/plb/opb/spi@ef600600/reg
/proc/device-tree/plb/opb/spi@ef600600/compatible
/proc/device-tree/plb/opb/spi@ef600600/cell-index
But I don't see any /dev/spidev* devices created or any mention of SPI
at boot time. I'm starting to suspect that I don't have the kernel
configured right, otherwise I would see at least the SPI driver
complaining about something, right?
Thanks,

* MPC8313 performance evaluation
From: Lutz Jaenicke @ 2009-08-06 18:00 UTC (permalink / raw)
To: linuxppc-dev
Hi!
I am currently evaluating the performance of the MPC8313E for firewall
(and VPN) purposes.
The results obtained do not match my expectations so I would be interested
in some discussion.
Test setup:
-----------
A linux 2.6.27 based firewall software is used. The software is the
same among
To be replaced: IXP42x custom made board (266MHz and 533MHz)
* MPC8343 custom made board (400MHz)
* MPC8313E-RDB Rev. C (333/333)
As a software firewall the throughput is determined by looking into
the routing information and IP headers, hence the performance is best
characterized by "frames/s" which is constant over the frame size
(as long as no limit is hit like the 100Mbit/s limit on the IXP42x).
With the MPC8343@400MHz I get a throughput of approx. 24500 frames/s
using the predefined firewall rules.
With the MPC8313 I get a significantly lower value:
MPC8313@250MHz 12500fps
MPC8313@333MHz 14500fps
MPC8313@416MHz 15500fps (333MHz type, overclocked)
Kernel 2.6.27 with SKB recycling from later versions and the
e300c2/c3/c4 TLB errata workaround. Some pure computational benchmark
with small footprint (namely "openssl speed") which should fit into
the cache size indicates the perfect 3/4/5 ratio used.
Some discussion with the the freescale rep. lead to the CSB frequency
of the 8313 (166MHz) being significantly lower than that of the 8343.
Is the CSB the critical point here?
Note: the IXP42x uses an internal bus speed of 133MHz and operates
at frame rates similar to the 8343...
Does anybody else have numbers for a firewall scenario using 8313
and/or other processors of the family?
Best regards,
Lutz
PS: Yes, I know that absolute numbers will be hard to compare with
other scenarios but relative values would be quite interesting as
well.

What DDR frequencies (and width) are you running the 8343 vs 8313 at.
This can have a significant impact on performance.

Check that the result of kmalloc/kzalloc is not NULL before dereferencing it.
The semantic match that finds this problem is as follows:

Hrm... start_kernel is very very early... strange. Can you double check
that the actual kernel image contains the right stuff ? Also, what
distro are you using to test that and how are you booting that kernel ?
You can always add something to prom_init.c to test (though beware you
aren't relocated yet so you need to offset the addresses).
Cheers,
Ben.

BTW. Corruption looks like bi_recs... ie, broken yaboot. This was fixed
recently, yaboot would eventually crap over the kernel for certain sizes
of the kernel image.
0x1010 = BI_FIRST
0x1013 = BI_BOOTLOADER_ID followed by 0x7961626f6f74 which is
"yaboot" :-)
0x1016 = BI_MACHTYPE
etc...

Ben.

Check whether index is within bounds prior to calculating a
possibly-invalid address.

Not unless all your partitions are 1 byte long ;)
The number is the offset into the device. Here is an example partition
table from the warp:
partition@0 {
label = "kernel";
reg = <0x00000000 0x00200000>;
};
partition@200000 {
label = "root";
reg = <0x00200000 0x03E00000>;
};
partition@40000000 {
label = "persistent";
reg = <0x04000000 0x04000000>;
};

but the goal is to use cpu offline to save power, right? So we still have

My original concern about Venki's patch is the C-state limition, but Venki
thought if CPU has the limition, CPU should disable specific C-state, so this
isn't a problem. I had no objection about the infrastructure itself, but just
wonder why we need it.

* [PATCH] powerpc/85xx: Move mpc8536ds.dts to address-cells/size-cells = <2>
From: Kumar Gala @ 2009-08-07 2:08 UTC (permalink / raw)
To: linuxppc-dev
Change the top-level #address-cells and #size-cells to <2> so the
mpc8536ds.dts is easier to deal with both a true 32-bit physical
or 36-bit physical address space.

* [PATCH] powerpc/85xx: Added 36-bit physical device tree for mpc8572ds board
From: Kumar Gala @ 2009-08-07 2:08 UTC (permalink / raw)

Added a device tree that should be similiar to mpc8536ds.dtb except
the physical addresses for all IO are above the 4G boundary.
