would it make sense to sort this list alphabetiacally? At the moment
we can setill easily find each board, but assume that list grows to 50
boards names...

Is this arch/ppc or arch/powerpc? I remember fixing this a while ago in
arch/ppc:
commit 67a35ce785b1d11d09bf528c166ea26d489a4bd6
Author: Stefan Roese <sr@denx.de>
Date: Thu Aug 2 14:15:22 2007 +0200
ppc: Fix problem with recursive NDFC platform_device resource management
This change fixes a problem with a resursive platform_device resource
management of the AMCC 4xx NDFC. Without this fix a "cat /proc/iomem"
leads to an infinite loop of printing the "ndfc-nand.0" resource.

* 2.6.24-rc2-git powerpc - kernel build fails !CONFIG_SMP

Hi,
The 2.6.24-rc2-git1 kernel build fails with randconfig on powerpc,
CC arch/powerpc/mm/tlb_64.o
arch/powerpc/mm/tlb_64.c: In function ‘pgtable_free_now’:
arch/powerpc/mm/tlb_64.c:71: error: ‘pte_free_smp_sync’ undeclared (first use in this function)
arch/powerpc/mm/tlb_64.c:71: error: (Each undeclared identifier is reported only once
arch/powerpc/mm/tlb_64.c:71: error: for each function it appears in.)
make[1]: *** [arch/powerpc/mm/tlb_64.o] Error 1
make: *** [arch/powerpc/mm] Error 2
The function pgtable_free_now is defined within CONFIG_SMP, and its not set in the
config.

Yeah I've seen it, recognise your name from the top of the device tree
definition, and I must say, it's not the most ideal...

Why? Freescale's chip, open standards, just design it right, and tell
the community they should be conforming with it.
The slow community process would have had the Efika come out this
month instead of this time last year if we had waited to fix the
device tree to "the right way to do it".
The device tree, hardware description in general, is down to the
silicon vendor and ODM, and should provide description of the
hardware which allows any driver (not just the ones in the BSP)
to get enough information from the tree where necessary.
I don't see that in the MPC5200 tree and I still don't see it in
the examples of the MPC5121E tree.
I also note the few users of the MPC5121E that there are outside
of Freescale, aren't involved (ahem) in this process unless they
join these mailing lists. You can't discuss anything on here with
that chip, it's locked down by NDA, release date tenuous, feature
state tenuous.. documentation is in draft/preliminary and nobody
else has it.

It is in this case isn't it? The errata states that it only appears
on that particular revision.

It shouldn't be a configuration option at all in my opinion :)
You either fix the bug or you don't, if you have to fix it in a
generic, multi-chip (5200/5200B) API like the PCI stuff, it
should be handled on a if/else basis. There's practically no benefit
to having it as a configuration option and being able to compile
it out, in fact.. it rather makes the whole presence of the fix
more complicated (to support 5200 and 5200B you need to compile
in the fix, and that means 5200B chips are implementing it when
they don't need to - and you need to recompile to fix it).

I disabled the powersaving code by adding powersave=off to the kernel's
command line, but it didn't help. It seems to lockup whenever it tries to
access a filesystem.
Is there a way to debug it without a hardware debugger or can you
recommend a cheap hardware debugger?

* IRQs in i2c-mpc.c
From: Jon Smirl @ 2007-11-10 19:44 UTC (permalink / raw)
To: PowerPC dev list
I'm doing final clean up the i2c open firmware support. What is the
intention of this code? Is it meant for a missing IRQ attribute to
return a zero and not get an IRQ for the device? Does the device
function without an IRQ? If so, it needs a comment explaining things.
Otherwise IRQ of zero should be an error.
i2c->irq = irq_of_parse_and_map(op->node, 0);
if (i2c->irq <= 0) {
result = -ENXIO;
goto fail_irq;
}
if (i2c->irq != 0)
if ((result = request_irq(i2c->irq, mpc_i2c_isr,
IRQF_SHARED, "i2c-mpc", i2c)) < 0) {
printk(KERN_ERR "i2c-mpc - failed to attach interrupt\n");
goto fail_irq;
}

* [PATCH] [POWERPC] Fix CONFIG_SMP=n build error on ppc64
From: Olof Johansson @ 2007-11-10 20:59 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev, Ingo Molnar, linux-kernel, Kamalesh Babulal
[POWERPC] Fix CONFIG_SMP=n build error
The patch "KVM: fix !SMP build error" change the way smp_call_function()
actually uses the passed in function names on non-SMP builds. So
previously it was never caught that the function passed in was never
actually defined.
This causes a build error on ppc64_defconfig + CONFIG_SMP=n:
arch/powerpc/mm/tlb_64.c: In function 'pgtable_free_now':
arch/powerpc/mm/tlb_64.c:71: error: 'pte_free_smp_sync' undeclared (first use in this function)
arch/powerpc/mm/tlb_64.c:71: error: (Each undeclared identifier is reported only once
arch/powerpc/mm/tlb_64.c:71: error: for each function it appears in.)
So we need to define it even if CONFIG_SMP is off. Either that or ifdef
out the smp_call_function() call, but that's ugly.

Hi all,
in mpc8xx_wdt.c in linux2.4 (denx distribution) piscr is 16bit long but in the same file in linux 2.6.19-2 (denx distribution) is read and written with in_be32 and out_be32. It's strange.
Bye.

Looking at the current driver it looks like we could get ride of if
check since the previous code checked the return of platform_get_irq().

The code was a snippet from the larger patch that is converting i2c

I think the lack of an IRQ in the device tree should be an error. If
the IRQ value is zero, than its zero.

irq_of_parse_and_map() returns NO_IRQ when the irq parameter is missing.
This API appears to be broken. In asm-powerpc/irq.h NO_IRQ is defined
as (0). There is no way to tell an error in the attribute from a valid
attribute selecting interrupt zero.
NO_IRQ used to be (-1).
/* This number is used when no interrupt has been assigned */
#ifdef CONFIG_PPC_MERGE
#define NO_IRQ (0)
#else
#define NO_IRQ (-1)

According the UM, the PISCR is indeed a 16 bit register.
The current header files also declare a 16 bit register:
include/asm-ppc/8xx_immap.h: ushort sit_piscr;

We don't support MPC8xx in the 2.6 kernel tree yet. What you see
there, is original kernel.org code - the code in question is commit
ID 398f6858.
I think you are right - this is a bug in the code. Please submit a
patch.

There are ways, sure, which probably involve adding prink's all over the
place to figure it out... could be some DMA issue for example, could be
pretty much anything. Have you tried booting an initrd with no disk

Many processors don't compare the reservation address locally. If
there's any valid reservation held by that processor, a subsequent
stwcx. will always succeed. That would make you scheme dangerous :-)

virq 0 is always illegal so if platform_get_irq() returns 0, it can be
safely treated as an error or the absence of irq, on both powerpc and
x86.

No, it is not broken. Interrupt numbers in arch/powerpc are virtually
mapped and 0 is never a legal value, thus NO_IRQ is 0. This was done in
part because Linus wanted it that way.
The hardware number can perfectly be 0 though, that's a different thing,
and has nothing to do with what you pass to request_irq().

Is the only error return from irq_of_parse_and_map() NO_IRQ? or can we
get standard negative returns? I started tracing out the returns from
irq_of_parse_and_map() but there are a lot of them.

* [RFC/PATCH] powerpc: Add support for 8xx style watchdog
From: Jochen Friedrich @ 2007-11-11 20:10 UTC (permalink / raw)
To: linuxppc-embedded@ozlabs.org
Hi,
this is an attempt to port the 8xx watchdog driver to ARC=powerpc. As the watchdog seems to
be similar on pq1 / pq2 and pq2pro platforms (except from the divider value), one driver
should be enough to support the whole family. Am i correct with this assumption?
Thanks,
Jochen
