* [PATCH] Add 7450 support to oprofile tools
From: Mark A. Greer @ 2006-09-08 22:57 UTC (permalink / raw)
To: oprofile-list; +Cc: linuxppc-dev, vwool
Hi,
I don't normally monitor or contribute to oprofile so I'm not sure
what your patch conventions are. If this email or patch is not in the
correct format please let me know what that format is and I'll resubmit.
Notes:
- This patch applies to oprofile-0.9.1.tar.gz
- Vitaly Wool contributed significantly to this patch.
Thanks,
Mark

This patch adds PowerPC MPC7450 support to the oprofile tools.
In reality, it also adds support for the MPC7445, MPC7447, MPC7447A,
MPC7448, MPC7455, and MPC7457 processors but has only been tested
on a MPC7447A. The 7450 name was chosen because it matches the name
used in the Linux kernel, <file:arch/powerpc/oprofile/op_model_7450.c>.
Note that not all of the performance counters available on those
processors were added to the events file but its a start, at least.

* Re: SystemAce Driver.
From: a sudheer @ 2006-09-09 0:04 UTC (permalink / raw)
To: Ameet Patil; +Cc: linuxppc-embedded
In-Reply-To: <45019041.2070409@gmail.com>
[-- Attachment #1: Type: text/plain, Size: 5489 bytes --]
Hi Ameet,
Today I tried the System ACE driver in interrupt mode.
The driver is connected to the processor through IRQ4 .
So, in xparameter_ml300.h , I have changed the
#define XPAR_OPB_INTC_0_SYSACE_COMPACTFLASH_SYSACE_IRQ_INTR 4
Also, in "xsysace_init", if I have xsa_device.gd = alloc_disk(16); , then
the kernel hangs.
So I have assigned alloc_disk(1), in which case the kernel boots-up fine.
But when I issue 'fdisk / mount ', it goes through - ' XSysAce_SectorRead'
which is being called from "xsysace_do_request".
And at the nd of the function it hangs. I couldn't trace exactly where it
hangs.
Could you please suggest some pointers to debug on this issue?
This is very critical for us and I am held up with this issue for the last 1
week.
Thanks so much for all your help.
Thanks
Sudheer

* 'make ARCH=ppc defconfig' failing for cross-compile
From: Judith Lebzelter @ 2006-09-09 0:05 UTC (permalink / raw)
To: linuxppc-dev; +Cc: paulus
Hello,
I have been doing cross-compiles for ppc and powerpc on my i686 system.
In order to do this I generate the .config file like this:
make ARCH=ppc defconfig
(or make ARCH=powerpc defconfig)
This is the error for ppc:
***
*** Can't find default configuration "arch/ppc/configs/common_defconfig"!
***
make[1]: *** [defconfig] Error 1
make: *** [defconfig] Error 2
If I replace this file 'arch/ppc/configs/common_defconfig' with an old one,
it does create my .config. The allmodconfig, allyesconfig and allnoconfig
work as I expect.
This is also happening for powerpc with a slightly different error where
it seems to get the architecture from my system rather than the
specified target architecture:
drivers/pcmcia/Kconfig:187:warning: leading whitespace ignored
***
*** Can't find default configuration "arch/powerpc/configs/i686_defconfig"!
***
make[1]: *** [defconfig] Error 1
make: *** [defconfig] Error 2
Could you suggest something that would make these cross compile builds
work again?
Thanks,
Judith

Hi Laurent,
I believe that I recall seeing the USB drivers in the "MPC8360E Device
Drivers - Release 1.1 GPL ", accessible from the main 8360 page.
http://www.freescale.com/files/netcomm/software/device_drivers/MPC8360EGPLDRV.zip
One little gotcha... When you unzip this archive, it's a windows
executable, but it doesn't have the '.exe' extension on the file, so
you'll need to add it by hand. I had to "contact my local FAE" just
to figure out that one when the darn thing wouldn't run. Too many
years of using Unix I guess.

No, rest assured, you're not. Try finding any information about the
eval board for the 8360 on freescale.com.

What support does the rest of the system provide for suspend/resume?
Generally the issue is not with getting the processor into sleep mode,
it's how you poke the rest of the system to put the RAM into
self-refresh mode, power down external buses, etc. That stuff tends
to be very platform-specific.

Yes you are right, I was asking about the cpu core not all the

We're hoping to get the Cell toolchain into Fedora Extras some time
soon, so you won't need to do anything special to find and install it.
In the meantime, it shouldn't be a problem -- I think it's normally
built on Fedora anyway.

* asm/*.h files missing for ppc arch.
From: Ming Liu @ 2006-09-09 15:05 UTC (permalink / raw)
To: linuxppc-embedded
Dear all,
Now I am trying to compile a driver module for my linux 2.6.16 kernel in
ML403 with CPU arch Powerpc 405. But when I include linux/module.h, and
then in module.h it includes linux/sched.h, and then in sched.h it includes
asm/param.h and asm/semaphore.h and asm/mmu.h......, the compiling errors
of "no such file or directory" appear. I found that there are NOT such
files in asm/ at all.(the asm/ is linked to asm-ppc/ for PPC405 arch) Where
are they then? I think when compiling modules, we must include
linux/module.h and then these asm/*.h files, right? Any implies are
appreciated. Thanks a lot for your telling.
Regards
Ming

How are you compiling? For 4xx, you still need to specify ARCH=ppc with
the make command. There is some makefile hackery that will then bring
in header files from asm-powerpc as needed.

In fact, I just try to compile the hello example in the book Linux Device
Driver chapter 2. The Makefile is listed as:
#Makefile
ifneq ($(KERNELRELEASE),)
obj-m := hello.o
else
KERNELDIR ?= /home/mingliu/linux-2.6.16
PWD := $(shell pwd)
default:
$(MAKE) -C $(KERNELDIR) M=$(PWD) modules
endif
Also, I have specified ARCH = ppc in my Linux kernel. But it seems that
there is still some problem. Thanks for your suggestion.
Regards
Ming

It's usually easier if you add your module to your copy of the kernel
sources and build it along with all the other modules.

How can I do that? I don't know how can I configure my driver and compile
it as a module. Which option shall I choose to configure my driver as a
module in menuconfig? Sorry that I am new to linux and I am anxious for
your helpful telling...

You need to at least the following steps:
1. Add your module to an appropriate location in the source tree, e.g.
drivers/net/ or drivers/char/, or whereever it fits best depending on
what it does.
2. Edit the Makefile in that directory so your driver gets built, e.g.
by adding a line 'obj-m += your-driver.o'.
The optional but recommended steps are:
3. Add the driver to an appropriate Kconfig file, typically in the same
directory as your driver, and change your Makefile to
use 'obj-$(CONFIG_YOUR_DRIVER) += your-driver.o'.
4. Learn to use 'quilt', or a similar tool, to manage your patch against
the kernel.
5. If you ask questions on the mailing list, make sure everyone has access
to your patch, e.g. by uploading it to a web site.

Sorry that my ip driver is so customed and I don't think anyone will have
interest on that. :-) However maybe later I can integrate other drivers in
the linux tree.

* highmem.h
From: Joseph Jezak @ 2006-09-09 20:43 UTC (permalink / raw)
To: linuxppc-dev
Hi everyone,
I think highmem.h needs to be copied from include/asm-ppc to
include/asm-powerpc. For instance, if you include linux/skbuff.h,
it includes linux/highmem.h. If CONFIG_HIGHMEM is enabled (which is
possible on PPC32), then linux/highmem.h includes asm/highmem.h
which isn't currently included in include/asm-powerpc.
Am I overlooking something here? For what it's worth, I noticed
this while building the sheep module in MOL.

* [RFC] inline hypercall implementation for pseries
From: Arnd Bergmann @ 2006-09-09 22:42 UTC (permalink / raw)
To: linuxppc-dev; +Cc: paulus, anton, arnd
This patch goes on top of the latest hcall statistics patch from
Mike Kravetz and changes the implementation of all hcalls to
end up in an inline assembly. This reduces the number of instructions
required on the side of the caller, so that in most cases we
don't need any stack memory at all.
Unfortunately, I don't have any hypervisor machine to try
this out, so I'm hoping someone else can test it and fix the
obvious bugs.
When statistics are enabled, the code is somewhat larger
than before, but for the regular case, it gets smaller,
this is the 'size' output for
arch/powerpc/platforms/pseries/built-in.o:
text data bss dec hex filename
45940 11584 8860 66384 10350 out of line, without stats
47152 16240 8860 72252 11a3c out-of-line, with stats
45492 11488 8860 65840 10130 inline, without stats
47264 16176 8860 72300 11a6c inline, with stats

Seems like defconfig has been removed, because there are so many
sub-platforms for ppc:
$ ls arch/ppc/configs/*defconfig | wc -l
56
Just pick the defonfig for your platform, for my PReP that'd be:
$ make ARCH=ppc CROSS_COMPILE=powerpc-604-linux-gnu- prep_defconfig

* Stupid Telnet Question
From: Martin, Tim @ 2006-09-10 18:07 UTC (permalink / raw)
To: linuxppc-embedded
I'm using ELDK 4.0 on a custom PPC74xx board, and NFS mounting the root
file system. When I use the default NFS directory (e.g.
/opt/eldk_4.0/ppc_74xx) read-write, I can telnet into the board fine
(after modifying /etc/xinetd.d/telnet of course).
But this default directory is overkill for my future needs, so I'd like
to use a smaller root file system (but still NFS mount it). As a start,
I looked at the ramdisk in ppc_74xx/images. I unzipped the ramdisk, and
NFS mounted that as the root file system.
I'd also like to have the root file system mounted read-only. So I
attempted to fix all the obvious problems I ran into with mounting ELDK
ramdisk filesystem read-only. This consisted of:
1) "mount -n" ing everything that needed to be mounted, so /etc/mtab
wasn't updated
2) Creating a tmpfs /tmp ramdisk
3) Symlinking /var to /tmp/var, so I can run syslog
4) Symlinking /dev to /tmp/dev, so I can mknod devices in the /etc/rc.sh
script. For starters, I just copied the contents of ELDK_MAKEDEV into
that script, but I will prune it down as I find device files I don't
need. This way the devices can be read-write.
5) Putting those same devices in the /tmp/dev directory so that I could
solve the "Unable to open initial console" chicken-egg problem of no
device files being present when the root fs is mounted before the rc.sh
script runs.
The above steps work in-so-far as I can boot the board and work from the
serial console. Now I'd like to get telnet working. When I just telnet
locally from the serial console to the board (using the loopback IP
127.0.0.1) the telnet daemon connects, but the login program doesn't
give me a chance to type a username or login. =20
Question: What stupid thing have I done to cause this and how can I fix
it?
-------------------------------------------------
This is what my console session looks like:
# telnet 127.0.0.1
Entering character mode
Escape character is '^]'.

Wolfgang, Aleck,
I think this patch
http://ozlabs.org/pipermail/linuxppc-embedded/2006-August/023912.html
explains the inability to use u-boot for the ml403 (and ml3xx) for the
2.6 kernel.

For security reasons, Telnet is typically set up so
that you can't log in using 'root'. This is because
the data channel isn't encrypted so passwords are
easily compromised. If you don't have any other users
set up, it will give the behaviour that you're seeing.
It's been a while since I've done this, but I think
you need to edit /etc/xinetd.d/telnet to allow root
use. Or add a user. Or install SSH.
cheers,
Ben
