I got a merge conflict on Documentation/powerpc/booting-without-of.txt,
which I tried to fix up. I may or may not have succeeded.
The issue was the interaction of David Gibson's device-tree-aware EMAC
driver which got merged with the net driver update through the networking
tree, and all the other new cases added in the PPC tree.
I think I merged it ok, but you guys should check and send me any fixes.

Well... maybe. Exactly how to sensibly propogate the information up
to userspace depends on the type of device and other factors. In most
cases I'd expect some kind of kernel intermediary between the device
tree and udev, but there might be instances where it would make sense
for udev to directly access /proc/device-tree/aliases via a helper
program.
In any case, if the kernel does provide some sort of name/number for
the device, you can use the aliases for that.

Well, be careful, and take that example with a grain of salt. I made
it up on the spot without checking a lot, so although it gives you the
general idea, I probably haven't followed conventions for the names of
the aliases and so forth.

I believe current standard practice is to bulid dtb aware u-boot
images by pointing at dts files from the kernel tree. u-boot doesn't
have it's own repository of dts files.

I think it should be DEVICE_TREE="kilauea.dts". DEVICE_TREE will
actually be ignored for building the uImage in any case, but this way
it will be correct if we ever do add a cuboot or other dtb-requiring
bootwrapper for Kilauea.
This is, of course, why CONFIG_DEVICE_TREE makes no real sense and
never has: it's a per-image, not a per-configuration variable.

Actually it's ambiguous whether TASK_SIZE or PAGE_OFFSET is correct in
most of these cases (KERNELBASE is certainly wrong, though).
TASK_SIZE is the top of the userspace mapped area, PAGE_OFFSET is the
bottom of the linear mapping. So, strictly speaking there are 3 paths
for the miss handlers: < TASK_SIZE => user mapping, >= PAGE_OFFSET =>
kernel mapping, between the two => immediate fault.
We get away with a two way comparison on 32-bit because, a) they have
the same value and b) none of the pagetables, user or kernel, should
have any entries in the in between region so we'll end up in
do_page_fault in the end, anyway.

You do need to have the 'console=ttyCPM0..." line. The system is
booting, so you are most of the way there. The next step is to find
out *where* it is failing and try to get a backtrace. If you've got a
debugger you can try halting the processor to see where the PC is
stuck. That will tell you if you are stuck on a infinite loop
somewhere, or if the CPM driver is causing an oops. (Look in
System.map for executable code addresses)
Cheers,

* [PATCH 1/2] [V3] Replace NT_PRXFPREG with ELF_CORE_XFPREG_TYPE #define
From: Mark Nelson @ 2007-10-12 2:40 UTC (permalink / raw)
To: Kumar Gala; +Cc: PowerPC dev list, Paul Mackerras, Linux Kernel Mailing List
In-Reply-To: <470ECFF7.9040008@au1.ibm.com>
Replace NT_PRXFPREG with ELF_CORE_XFPREG_TYPE in the coredump code which
allows for more flexibility in the note type for the state of 'extended
floating point' implementations in coredumps. New note types can now be
added with an appropriate #define.
This does #define ELF_CORE_XFPREG_TYPE to be NT_PRXFPREG in all
current users so there's are no change in behaviour.
This will let us use different note types on powerpc for the
Altivec/VMX state that some PowerPC cpus have (G4, PPC970, POWER6) and
for the SPE (signal processing extension) state that some embedded
PowerPC cpus from Freescale have.

Sorry for the patch noise but please disregard this patch - a line is longer than 80 characters and I'd hate to be brought up on that...
V3 will be the perfect version then :)
Thanks and apologies again!
Mark.

Yeah, I think I misinterpreted BenH way back when. This looks ok, and
means serial will be initialized earlier than of_serial, which would
be nice.

One more for you. This is preparation for the libfdt merge.
Add memchr() to the bootwrapper
This patch adds a memchr() implementation to the bootwrapper. libfdt
will need this.

Not the taken branch of them, no. :) But making it past them as fast
as possible when they're not tripping is always good.

Sure. Just looking at a couple of cases:
On range comparisons such as (a < CONST):
* without this patch, you end up with a comparison, then a cr-to-cr op +
mfcr + mask operation + tdnei.
* with the patch, you get a comparison and a conditional branch with
twi out of line.
On multiple comparisons like WARN_ON( a || b), it seems that there's an
added li to make the tdnei always hit for the first case. There it uses
a regular conditional branch, so no real difference in generated code
besides that.
Code examples. This was with a ppc64_defconfig, so CONFIG_POWER4_ONLY
wasn't enabled. It uses mfocrf when it is, which is alot cheaper. Still,
the rest of the code sequence is the same:
void irq_free_virt(unsigned int virq, unsigned int count)
{
unsigned long flags;
unsigned int i;
WARN_ON (virq < NUM_ISA_INTERRUPTS);
WARN_ON (count == 0 || (virq + count) > irq_virq_count);
spin_lock_irqsave(&irq_big_lock, flags);
Without the patch:

* [PATCH 1/2] [V2] Replace NT_PRXFPREG with ELF_CORE_XFPREG_TYPE #define
From: Mark Nelson @ 2007-10-12 2:15 UTC (permalink / raw)
To: Kumar Gala; +Cc: PowerPC dev list, Paul Mackerras, Linux Kernel Mailing List
In-Reply-To: <470ECFF7.9040008@au1.ibm.com>
Replace NT_PRXFPREG with ELF_CORE_XFPREG_TYPE in the coredump code which
allows for more flexibility in the note type for the state of 'extended
floating point' implementations in coredumps. New note types can now be
added with an appropriate #define.
This does #define ELF_CORE_XFPREG_TYPE to be NT_PRXFPREG in all
current users so there's are no change in behaviour.
This will let us use different note types on powerpc for the
Altivec/VMX state that some PowerPC cpus have (G4, PPC970, POWER6) and
for the SPE (signal processing extension) state that some embedded
PowerPC cpus from Freescale have.

Ooops... Right you are - very good pickup :) Fixed in a new version (will send promptly).
Thanks!

It might be more instructions but it takes fewer cycles, I would
expect. Do you have the actual instruction sequences to compare?

Yeah true. I figured it was nice to have it spelled out in the code that
the routine is only valid for certain values of r - but I'm not fussed.

Paulus mentioned on IRC that he preferred it that way. I'll leave it up

Just seems a little unnecessary given that the function in question is
static, that's all...

Hi,
I am facing kernel hang when ATM Tx command is issued. I am using SUSE
