The arg size is the size of the field in bytes:

  dump_field(str, h->magic_num, sizeof(h->magic_num));

To me, the name length doesn't seem to convey that.

* [patch v4] PS3: Fix printing of os-area magic numbers
From: Geoff Levand @ 2007-12-23 17:41 UTC (permalink / raw)
  To: Paul Mackerras; +Cc: Geert Uytterhoeven, linuxppc-dev@ozlabs.org
In-Reply-To: <473F6A28.5000309@am.sony.com>

Subject: ps3: Fix printing of os-area magic numbers

Fix a bug in the printing of the os-area magic numbers which assumed that
magic numbers were zero terminated strings.  The magic numbers are represented
in memory as integers.  If the os-area sections are not initialized correctly
they could contained random data that would be printed to the display.
Also unify the handling of header and db magic numbers and make both
of type array of u8.

CC: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>

v2: o handle unprintable chars.

v3: o breakout string dump into helper dump_field()
    o unify handling of header and db magic numbers

v4: rename dump_field() args

* [PATCH] i2c: adds support for i2c bus on Frescale CPM1/CPM2 controllers
From: Jochen Friedrich @ 2007-12-23 19:06 UTC (permalink / raw)
  To: Jean Delvare; +Cc: Scott Wood, linux-kernel, i2c, linuxppc-dev

Using the port of 2.4 code from Vitaly Bordug <vitb@kernel.crashing.org>
and the actual algorithm used by the i2c driver of the DBox code on
cvs.tuxboc.org from Tmbinc, Gillem (htoa@gmx.net). Renamed i2c-rpx.c and
i2c-algo-8xx.c to i2c-cpm.c and converted the driver to an
of_platform_driver.

* [PATCH] Do not fail build if mkimage is not available
From: Michael Buesch @ 2007-12-23 19:31 UTC (permalink / raw)
  To: paulus; +Cc: linuxppc-dev

This fixes the boot image wrapper script to not fail the kernel
build if mkimage is not available.
As some distributions don't ship the mkimage program and I am not
interested in uboot images anyway, I don't want to fail the whole kernel
build process because of this unneeded dependency.

Simply drop an error message, but don't fail the build.

This is probably OK for now, but I'm working on getting mkimage merged
into the kernel so it will just get ripped back out later if I'm
successful.

Yeah, cool. I am fine with this. :)

I just don't want to install a tool into my operating system that
I do not need. Shipping it with the kernel is the best option.

* Build breakage on powerpc with 2.6.24-rc6-mm1
From: Balbir Singh @ 2007-12-23 22:41 UTC (permalink / raw)
  To: linuxppc-dev, akpm, gregkh; +Cc: linux-kernel

Hi,

I see the following error with the iseries_veth driver in 2.6.24-rc6-mm1

drivers/net/iseries_veth.c: In function ‘veth_init_connection’:
drivers/net/iseries_veth.c:818: warning: unused variable ‘rc’
drivers/net/iseries_veth.c: In function ‘veth_probe_one’:
drivers/net/iseries_veth.c:1086: error: ‘veth_port_ktypeq’ undeclared
(first use in this function)
drivers/net/iseries_veth.c:1086: error: (Each undeclared identifier is
reported only once
drivers/net/iseries_veth.c:1086: error: for each function it appears
in.)
make[2]: *** [drivers/net/iseries_veth.o] Error 1
make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2

Here's a patch, compile tested to fix the compilation problem


Remove unused variable rc and fix a typo, veth_port_type was called
veth_port_typeq

Is this bus interface really board specific?  I would have thought the
localbus bridge would have been part of the SoC in which case the
compatible string should mention the 823 rather than the dbox.

It's also usual for these localbus things, to have #address-cells of
2, with the chipselect explicitly present as the first cell.

What are these mysterious enx, gtx, etc. devices?  Some comments might
be nice.

compatible strings should be listed with most specific first, most
general last.  That would put "cfi-flash" after the dbox2 specific
string, I believe.

Is this representing an LCD controller, or the display itself.  Either
way I'm surprised there's something here in the SoC that has a
compatible string that's not "fsl,something"

Ok.  We don't have a really good mechanism for that at present - for
any of the input forms.  I was thinking about trying to hook that into
the checking framework - have a special sort of check that doesn't do
anything when invoked as a check, but can be "pre-failed" by the input
parsing code.

Uh, yeah.  That's just me being an old-timer and remembering the days

Hrm.  Not all that fond of those, but we'll see.  I guess
C-function-like syntax does make a certain amount of sense in the
context of the expression syntax we intend to introduce.

... and this cause build failures for most of the mpc8xxx defconfigs.
The reason is that e200 and e500 are both lumped under CONFIG_FSL_BOOKE
in cputable.c, but you have them segregated more here.  I've added a
fix that just does CONFIG_FSL_BOOKE here to match cputable.c.

So if this "seems semi-reasonable", why was the result
gregkh-driver-driver-add-driver_add_kobj-for-looney-iseries_veth-driver
containing "Hopefully no one uses this function in the future and the
iseries_veth driver authors come to their senses so I can remove this
hack..." as part of its comment.  If you expect respect, you need to
treat others the same way ...

If what the driver writers are doing is "looney" (in your opinion), then
please describe a better way of doing what they are trying to do.
Sometimes, if people have to abuse the infrastructure, it is possible that
the infrastructure is lacking?

Do you have a /dev/ttys/0? First serial port is normally /dev/ttyS0.

For the power architecture, no, I do not.  I used to, but my cross-build
box died and I haven't taken the time to set it all up again.  For i386
and x86-64 I do build everything, and as that's 99% of the users, it's
usually fine :)

I did start to try to get a s390 cross-build working, but ran out of
time a week or so ago...

Well, sarcasm doesn't come accross very easily in changelog comments it
seems :)

In thinking about this some more, no, I think you all are abusing the
infrastructure here.  This is the ONLY driver in the entire kernel tree
that thinks it is acceptable to hang kobjects off of the driver
structure.  For some reason, no one else does this either because they
never would think of doing such a thing, or that they are not as unique
as this driver.

So I take back the "semi-resonable" statement above.  Please prove to me
that:
	- it is ok to hang kobjects off of a driver when:
		- no userspace tool will ever be notified that they have
		  been created
		- no known userspace library knows how to find such
		  attributes (libsysfs can't do that last I looked, and
		  it's no longer maintained.)
		- there is no documentation in the Documentation/ABI/
		  explaining this usage.
	- this can not be just a easily expressed in debugfs, or some
	  other representation (netlink for configuration, configfs,
	  some other location in sysfs, a driver-specific filesystem,
	  etc.)
	- that there is a tool out there using this current interface.

I don't like this usage of sysfs as it is very abnormal, and we are
trying very hard to fix up the rough edges here, to:
	- make it easier to program to and not get things incorrect
	  within the kernel
	- present a unified, semi-sane interface that is documented well
	  to userspace so users don't get even madder then they
	  currently are.


thanks,

Hi Olof,

Thanks a lot for replying to the query posted. It works now. Initially I had
created the device file tts/0 instead of ttyS0 and still faced the same
issue. Now I have the ttyS0 created and created tty0 and also modified the
inittab as below,

--------------------------------------------------------------------------
Original Config ( Not Working )
--------------------------------------------------------------------------
::sysinit:/etc/init.d/rcS
#::askfirst:-/bin/sh
::ctrlaltdel:/sbin/reboot
::shutdown:/sbin/swapoff -a
::shutdown:/bin/umount -a -r
::restart:/sbin/init
::respawn:/sbin/getty 38400 tts/0

Created the following devices in /dev through
mknod -m 660 console c 5 1
mknod -m 660 xsa b 254 0
mknod -m 660 xsa1 b 254 1
mknod -m 660 xsa2 b 254 2
mknod -m 660 xsa3 b 254 3
mkdir tts
cd tts
mknod -m 660 0 b 4 64
cd ..
mknod -m 660 null c 1 3

Working Config

::restart:/sbin/init
::respawn:/sbin/getty -L ttyS0 38400 vt100

# ls -al

Now I m able to see the login prompt :) .

I would be very grateful if the following questions could be addressed,

1. Does the inittab format changed for Linux 2.6. The old one was from
mkrootfs (which I think is pretty old). I could see some changes in the
"respawn" line.

2. Is it required to run the tty0 along with ttyS0. Is this is mandatory. I
assumed all these days console and ttyS0 should be sufficient.

3. A very basic question : What is the clear difference between ttyS0 ( UART
Driver ), console and tty0. To my understanding, ttyS0 is the first port
UART 's driver (for 16550/8250) which deals with the hardware as such by
writing and reading the registers. tty0 is virtual console, something to do
with telnet sessions. But I dont clearly understand why console and tty0 are
both required or not. Please correct me if my understanding is wrong.
Merry Christmas.

Thanks and Regards,
Ramkumar
