* 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

* 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)

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

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.

* [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.

Hey, we have code to boot the Freeserv with chrp/Of, need to clean it up and
merge it though. Would this be a good thing to submit for mainline inclusion,
it is a couple of lines at most, altough there is some reuse of the interrupt

* MPC8270 with preemptible kernel stucks in early console write
From: claus @ 2005-10-20 13:52 UTC (permalink / raw)
To: linuxppc-embedded
Hi there,
I'm porting the 2.6.13.2 kernel to a custom board with a MPC8270.
If I compile the kernel preemptible then it gets stuck at the following
line in the cpm_uart_console_write function:
while ((bdp->cbd_sc & BD_SC_READY) != 0)
;
The early_console output works fine in the beginning of the boot but then
it gets stuck after the line "checking if image is initramfs...it isn't
(no cpio magic); looks like an initrd" is printed. The problem doesn't
seem to have anything to do with the initramfs detection though.
I can see with the debugger that the descriptors are OK and the buffers
are filled with correct data but it seems that the SCC is not sending the
characters and the main core is stuck waiting for a descriptor to be
ready for use.
Everything works fine if the kernel is not configured preemptible.
Has anyone else had similar behavior?
Any ideas?

* How to make mudules on linux-ppc2.6.12
From: JohnsonCheng @ 2005-10-20 10:56 UTC (permalink / raw)
To: linux-ppc-embedded
[-- Attachment #1: Type: text/plain, Size: 755 bytes --]
Dear All,
I just write a "hello world" module code, but I can't compile it for
ppc2.6.12.
My Makefile is list as following:
obj-m := test.o
all:
make ARCH=ppc CROSS_COMPILE=powerpc-linux- -C /root/linux-2.6.12.3
SUBDIR=. modules
When I run make, no error message output, but I find no test.ko modules. The
output message is list as following:
make ARCH=ppc CROSS_COMPILE=powerpc-linux- -C /root/linux-2.6.1
2.3 SUBDIR=. modules
make[1]: Entering directory `/root/linux-2.6.12.3'
CHK include/linux/version.h
make[2]: `arch/ppc/kernel/asm-offsets.s' is up to date.
Building modules, stage 2.
MODPOST
make[1]: Leaving directory `/root/linux-2.6.12.3'
Do anyone can give me some help ?
Thanks,
Johnson Cheng

Is there any driver for security-engine on mpc8248?
If yes, what can it do? where can I found it?

OK. I can't find an up to date one any more. From the processor
manuals there are overlapping numbers (unless that was just
an oversight during editing).

Yeah, some people have tried probing peripherals to discover
the type of processor, but that was quickly proven to not work.
Thanks.

I don't understand in what way Marcelo wants to use it, but
from my understanding and a quick look of the Freescale product
summary pages it's the opposite of what you're indicating.
I believe the PARTNUM identifies the family not the part.
You can't tell an 885 from an 870 (IMMR contains 0x09xx).
Similarly you can't tell an 860EN from an 860T (IMMR
contains 0x00xx or 0x05xx).
But you can tell an 860 from an 880 which are in different
families. Note that it's not always obvious which parts
are in the same family.

Also just because a feature isn't supposed to be present
doesn't mean it's not.
We bought 860EN (4 SCCs) parts but Motorola accidentily
shipped us 860DE (2 SCCs) parts. We installed, tested and
shipped a few of these parts using all 4 SCCs without
problem. It wasn't until another unrelated problem occurred
that we noticed that we had used a tray of the wrong part.

* [PATCH] (modified) Merge types.h
From: Becky Bruce @ 2005-10-19 23:45 UTC (permalink / raw)
To: linuxppc64-dev, linuxppc-dev
powerpc: Merge types.h
This patch merges types.h into include/asm-powerpc. The only real change is
the removal of the include of linux/config.h from the 32-bit version - it
doesn't appear to be necessary.
This patch has been built on several different 32 and 64-bit platforms,
and booted on mpc8540_ads.
This patch supersedes the previous patch [PATCH] Merge types.h

Gack! While I doubt that should break anything, I can't promise 100%
that it won't. I'll resubmit with that wrapped up in a nice shiny

Thanks for the catch - I wouldn't want irate users picketing my house :)

* [PATCH] ppc32: ppc_sys fixes for 8xx and 82xx (whitespaces fixed)
From: Vitaly Bordug @ 2005-10-19 17:57 UTC (permalink / raw)
To: Andrew Morton; +Cc: linux-kernel, Kumar Gala, linuxppc-embedded list
[-- Attachment #1: Type: text/plain, Size: 726 bytes --]
This patch fixes a numbers of issues regarding to that both 8xx and 82xx
began to use ppc_sys model:
- Platform is now identified by default deviceless SOC, if no
BOARD_CHIP_NAME is specified in the bard-specific header. For the list
of supported names refer to (arch/ppc/syslib/) mpc8xx_sys.c and
mpc82xx_sys.c for 8xx and 82xx respectively.
- Fixed a bug in identification by name - if the name was not found, it
returned -1 instead of default deviceless ppc_spec.
- fixed devices amount in the 8xx platform system descriptions

* PPC 440 / JFFS2 checksum question.
From: Andrew McCarthy @ 2005-10-19 17:36 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 2210 bytes --]
We have some PPC440GX based blade servers that boot
from flash. My boss wants me to add
additional checksums somewhere in the JFFS2 partitions
as an overall check of the JFFS2 filesystem images that
we burn to flash. Once the image is burned, that file
system is never written to again. (That's the theory anyway).
So every time they boot they want to read these checksum
out of the flash and use it to decide if they want to/can boot
with that filesystem or fallback to another one.
Each copy of the kernel has its own JFFS2 partition.
The root file system has its own JFFS2 partition. I don't
understand why they don't just write everything to one
JFFS2 partition. They say it is because they are
worried about power failure while writing to the flash and want
to isolate any write failures.
( I tried to tell them that the journaling already handles
that case quite well - but they are non-believers)
Some questions;
1) Is a filesystem-wide checksum really necessary or
is it kind of silly?
1.1) Doesn't JFFS2 already do some integrity checking after
it finishes writing a file? Are there checksums or anything that
serves the same function? They want to avoid having to
checksum the entire filesystem at boot time (due to quick
boot time requirements) - is there some field or fields, or technique that
can quickly tell me if the filesystem is ok?
2) Is there any place within the bounds of a JFFS2
partition that is safe from being overwritten? before and
after checksums could be placed there.
2.1) Is there any way to create such a place? for example,
by appending the checksums to the end of some filesystem-wide
structure like a super block? Or maybe it can be hidden in
a couple of inodes that are never overwritten.
What I'm looking for regarding this adding extra checksums into the
JFFS2 image is:
3.1) How can it be done?
3.2) Why might it be unnecessary or even inadvisable?
3.3) Why can't it be done?
Once I understand the answers to these questions I can
go back and see what they want to do.
In the meantime, I am dumping and analyzing the JFFS2
filesystems we have and reading the code trying to find the
answers.
thanks for your time.

* [PATCH] powerpc: merge types.h
From: Becky Bruce @ 2005-10-19 16:55 UTC (permalink / raw)
To: linuxppc64-dev, linuxppc-dev
powerpc: Merge types.h
This patch merges types.h into include/asm-powerpc. The only real changes
here are that umode_t has become short instead of int in the 64-bit case,
which appears to match what most other platforms have done. Also, the
32-bit version was #including linux/config.h - I have removed this as it
does not appear necessary.
This patch has been built on several different 32 and 64-bit platforms,
and booted on mpc8540_ads.

Yes, this is exactly the way ML300 is booted (as regards to the code
currently in www.kernel.org's 2.6 tree).
Use 'make zImage' or 'make zImage.initrd' to get zImage.elf or zImage.initrd.elf.

There is U-Boot port for ML300 by Peter Ryser from Xilinx,
but I haven't tried using it (yet). IIRC there is an appnote
on Xilinx web site that describes how to boot the 2.4 kernel
with U-Boot (few modifications need to be done to the kernel).
Best regards,
Andrei

Hi,
Make sure ROOT_DEV is initialized to the correct device, for instance :
In Sandpoint.c (arch\ppc\platforms): =09
#ifdef CONFIG_ROOT_NFS
ROOT_DEV =3D to_kdev_t(0x00FF); /* /dev/nfs pseudo device */
#endif
There is no default value for it, except if you pass it on command line
Fabien

Another interesting bit of docs is MacTech.pdf (google for it) which
documents an early version of the mac-io chip that was used on some CHRP
machines.
In general, there is no complete documentation. I would say that the
linux source code is probably the best you can get in this regard.
Feel free to ask me questions about details
Ben.
