It is also known as HPC1, which is the discovery III based freesscale
reference design, as the HPC2 is the tundra based one.

* [PATCH] powerpc: Make sure we have an RTC before trying to adjust it
From: Kumar Gala @ 2005-10-20 16:43 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev, linuxppc64-dev
Its valid for ppc_md.set_rtc_time to be NULL. We need to check
that its non-NULL before trying to update the RTC.

* [PATCH] powerpc: some prom.c cleanups
From: Kumar Gala @ 2005-10-20 16:44 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev, linuxppc64-dev
On !CONFIG_PPC_MULTIPLATFORM _machine is defined as 0. This is ok, but
we can't assign a value to _machine then.
We may not have CONFIG_PCI available, so only build in support for
find_parent_pci_resource(), request_OF_resource(), release_OF_resource()
if PCI is enabled. This is probably not the long term fix but works out
for now.
Make reg_property64 contain 64-bit elements on a 32-bit machine.
Mark the deprecated prom.c functions as __deprecated.

* v2.6.13.4 : Bad page state at prep_new_page when booting with quik
From: Marc Zyngier @ 2005-10-20 17:53 UTC (permalink / raw)
To: linuxppc-dev
[-- Attachment #1: Type: text/plain, Size: 1262 bytes --]
List,
I finally managed to bring back to life an old Apus 3000/200 (PowerMac
6400 clone, 603e@200, no L2 cache, 144MB RAM). Kernel is vanilla
2.6.13.4, userland is Debian Sarge.
The strange thing is : while the machine boots perfectly with BootX,
it fills the console with messages like this when booted from quik :
Bad page state at prep_new_page (in process 'S70nviboot', page c04301e0)
flags:0x00000000 mapping:00000000 mapcount:1 count:1
Backtrace:
Call trace:

[c0004780] handle_page_fault+0xc/0x80
Trying to fix it up, but a reboot is needed
And no, rebooting doesn't help...
The system more or less manages to painfuly boot, still screaming on
the console. But the result is far from being usable.
Again, the very same kernel works perfectly when booted from BootX,
but I'd rather have the machine to stay headless, with serial console
hanging off the terminal server...
Does anyone have a clue, or at least a direction from where to start?
Thanks,
M.

* PowerPC/Linux device driver question
From: Madhu Saravana Sibi Govindan @ 2005-10-20 19:56 UTC (permalink / raw)
To: linuxppc-dev
Hello all,
I'm trying to write a device driver in linux on a PowerPC processor.
The device has been allocated a range of addresses in the physical
address space of the processor (IBM 440GP) - from 0x100000000 -
0x13fffffff. (FYI, the 440GP is a 32 bit processor using 36 physical
addresses, the processor's MMU appends the extra 4 bits to get a
36-bit physical address).
I'm not sure how to request this range of physical memory from the
kernel. I thought I could use ioremap to map this range into the
virtual space, but ioremap takes only an unsigned long as an argument,
which is only 32 bits on 440GP. I don't think I can represent the range of =
my
device with 32 bits.
Could someone tell me how to solve the problem? I want this range of
physical addresses to be associated with my device driver and how do I
do that?
Thanks in advance,
G.Sibi

Use the ppc-specific ioremap64() call.

I believe you've seen this before, but the link is still in the same
place... http://penguinppc.org/otherhw/#chrp
As I recall, though, the CHRP specification mandates such obsolete
features as an ADB controller, so claiming "CHRP compliance" may not be
all that special these days. :)

Dear Andy,
Thanks your reply. But I am sorry that it doesn't work on my box.
My kernel had been configured and compiled, and I also modify my Makefile as
following:
Obj-m := test.o
All:
$(MAKE) ARCH=ppc CROSS_COMPILE=powerpc-linux- -C /root/linux-2.6.12.3
SUBDIRS=$(PWD) modules
The output message is the same as before, no error message and no test.ko
module.
Thanks,

Dear All,
I just write a "hello world" module code, but I can't compile it for

When I run make, no error message output, but I find no test.ko modules. The

Do anyone can give me some help ?

Is this board available to anyone. I dont believe Freescale plans on

Well, it definitely looks like something is wrong :) Not sure what's up
at this point. Could be cache coherency not properly enabled on PSX
memory controller by Open Firmware maybe ...
It would be useful if you could dump the memory controller registers
between an OF boot and a BootX boot.
Look at this bit in pmac_setup.c:
sysctrl_regs = (volatile u32 *) ioremap(0xf8000000, 0x1000);
ohare_init();
The first line maps those registers, the second line enables the L2
cache on PSX memory controller. (The name "ohare_init() is actually a
bit bogus here, since that has nothing to do with ohare, but we do it in
ohare based machines only... go figure, that's pre-historical code,
certainly predates my involvement here :).
I'd suggest dumping to 8 or so first words of sysctrl_regs and checking
what difference is there.
Then, there is another blob that enables cache coherency on the PCI side
of Bandit/PSX in pmac_pci.c in init_bandit(). But this code seems to be
called for you ...
It could be something else tho ... like some problem with quik...
Ben.

Thanks for your kindly suggestion. I have found out the problem.
Just do some modification as following:

Dear Andy,
Thanks your reply. But I am sorry that it doesn't work on my box.
My kernel had been configured and compiled, and I also modify my Makefile as
following:
Obj-m := test.o
All:
$(MAKE) ARCH=ppc CROSS_COMPILE=powerpc-linux- -C /root/linux-2.6.12.3

The output message is the same as before, no error message and no test.ko

* status of kexec for ppc on 2.6.10, any gotchas?
From: Christopher Friesen @ 2005-10-21 5:03 UTC (permalink / raw)
To: Linux Kernel Mailing List, linuxppc-dev
I've been asked to look at kexec for ppc on 2.6.10. The syscall appears
to be present, but there seem to be additional patches for 2.6.10-mm at:
http://www.xmission.com/~ebiederm/files/kexec/
Are these patches needed?
I haven't been able to find any current official documentation, although
I found some old stuff from 2.5 and a writeup at:
http://www-128.ibm.com/developerworks/linux/library/l-kexec.html?ca=dgr-lnxw04RebootFast
Is there any official HOWTO on this? Any issues I should look at in
particular?
Thanks for any pointers,
Chris

And 32<->64 bits compatibility layer for 32bits apps is not needed,
so maybe they run a bit faster. Well, at this point IMHO 32-on-64
support may be dropped without regrets. Spending time for an useless
thing is - uhm - useless.

* Three-Speed Ethernet support on MPC8560 (CPM2 TSEC)
From: Nathael PAJANI @ 2005-10-21 8:05 UTC (permalink / raw)
To: linuxppc-embedded
Hi all!
I'm working on a port of linux (2.6.13-2) on an Actis-computer board,
based on the Freescale MPC8560 Processor.
I solved the problems I had with the init process, and I actually have
the console (SCC1) and one ethernet controler (FCC3) running.
I will now go on with the Three-Speed Ethernet Controler, and there
actually seem to be no support for it, but maybe I did not look at the
right place?
I got another question, about the FCC driver: it uses a "big" structure
"fcc_enet_t" wich seems to be aimed at stats. This is initialised, but I
did not find where this is used. Is it?
Thanks.

Hello!
Due to the fact that the in-kernel FPU emulation looks=20
broken on MPC8xx i want to build a complete soft-float
userspace.
While i was successful in compiling a glibc with -mcpu=3D860
and soft-float (and without memset.S) there's still floating
point in there. Does anybody have some pointers what else
needs to be removed?
TIA and best regards,

* kgdb support in Linux 2.6 for 8xx
From: Chris @ 2005-10-21 10:36 UTC (permalink / raw)
To: linuxppc-embedded
Hi,
It would be nice to be able to do some kernel debugging on my TQM823L
board running 2.6 (2.6.13.1, to be exact). I have two questions
1. Has anyone got kgdboe working in this configuration? If so, could you
give me a pointer to a patch?
2. kgdb over serial is lacking the getDebugChar and putDebugChar
functions that used to be in 8xx_io/uart.c. Has anyone done any work on
merging them into 2.6?
[OK, that's actually three questions. One just crept in]
Thanks in advance,
Chris

* Re: status of kexec for ppc on 2.6.10, any gotchas?
From: R Sharada @ 2005-10-21 11:02 UTC (permalink / raw)
To: Christopher Friesen; +Cc: linuxppc-dev, Linux Kernel Mailing List
In-Reply-To: <435876B8.9000706@nortel.com>
Kexec support involves kernel level support per architecture and
a user space kexec-tools.
Generic kexec kernel support for ppc (ppc32/GameCube) was added
sometime back by Albert Herranz, and I think they got included in 2.6.10-mm1
as per:
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.10/2.6.10-mm1/broken-out/
Albert's code was also posted on this site:
http://www.gc-linux.org/down/isobel/kexec/
ppc64 kexec kernel support was added recently (2.6.12-rc4-mm1)
Eric's site can be used for downloading the kexec-tools.
You may want to cross post kexec discussion mails to fastboot@osdl.org,
as that is the primary list where all kexec discussions happen.
Hope this helps
Thanks and Regards,
Sharada

Not exactly. I have implemented support for KGDB on cpm_uart driven
boards (most of 8xx use it), but it is only tested on 827x family.
Anyway, 8xx should work with minimal changes.

There is a kgdb community project - http://kgdb.sf.net. The attached
patch is for this one (it has been submitted but not in the CVS so far).

This add support for KGDB using cpm_uart driver.
Should work on all the boards utilizing it, tested on 8272ADS.
