Yes, 'kbdrate' is used here.

Try ebtables (http://ebtables.sourceforge.net/). You'll need to add
eth0 to a bridge first, though.

* [U-Boot-Users] Boot Count Limit
From: Jeff Angielski @ 2004-01-27 17:07 UTC (permalink / raw)
To: u-boot
Has anybody written the small application that resets the bootcount as
per the following description:
"It is the responsibility of some application code (typically a Linux
application) to reset the variable bootcount, thus allowing for more
boot cycles."
From the u-boot documentation site:
http://www.denx.de/twiki/bin/view/DULG/UBootBootCountLimit
If so, can you send it my way or tell me where to get it? I am trying
to not recreate the wheel yet again.... :)
Thanks,

* RE: List noise.
From: Brown, Len @ 2004-01-27 17:00 UTC (permalink / raw)

Sure, I'm open to moving the list off sourceforge if there is clearly a
better choice. Two other problems we've seen on sf are
1. latency is sometimes huge
2. archives sometimes unavailable, and not indexed by google.
In the mean-time, here are the mailman spam filters I've got on SF, a
couple I've added in the last 30-minutes. It doesn't look like it can
search for a _missing_ field -- only positive matches. I'm sure open to
suggestions for further improvement.
Thanks,

* [PATCH][2.6] PCI Scan all functions
From: Jake Moilanen @ 2004-01-27 16:55 UTC (permalink / raw)
To: Andrew Morton; +Cc: lkml
[-- Attachment #1: Type: text/plain, Size: 459 bytes --]
There are some arch, like PPC64, that need to be able to scan all the
PCI functions. The problem comes in on a logically partitioned system
where function 0 on a PCI-PCI bridge is assigned to one partition and
say function 2 is assiged to another partition. On the second
partition, it would appear that function 0 does not exist, but function
2 does. If all the functions are not scanned, everything under function
2 would not be detected.
Thanks,
Jake

* [PATCH] fix menuconfig choice item help display
From: Bjorn Helgaas @ 2004-01-27 16:55 UTC (permalink / raw)
To: kai, sam; +Cc: linux-kernel, kbuild-devel
This patch against 2.6.2-rc2 fixes menuconfig so it can display
help text for individual choice group config entries.
Previously it would only display the help text attached to the
"choice" item. There was no way to display the help attached to
individual config entries inside the choice group. Typically,
the "choice" item has no help text, and all the useful help is
attached to the individual entries, so this was a bit of a
problem.

* gdb problems
From: Christopher R. Johnson @ 2004-01-27 16:48 UTC (permalink / raw)
To: linuxppc-dev
Maybe not the right list for this, if you have a suggestion for
somewhere better let me know...
My new tool chain build is working well, except that debugging with
gdb/gdbserver is somewhat broken. I figured out that I needed thread_db
and have that built in now and delivered to the target platform.
Problem #1: When I start host side gdb, I get the message:
warning: unable to find dynamic linker breakpoint function
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code
I don't need to debug initializers, so I set a breakpoint at main and
continue. Two error messages appear:
Error while mapping shared library sections:
/lib/ld.so.1: No such file or directory
Error while mapping shared library symbols:
/lib/ld.so.1: No such file or directory
The program starts and breakpoint don't work.
Problem #2: (Maybe related?) on the target side gdbserver, after
starting things with "c" on the host side, this message appears:
gdb: error initializing thread_db library.
gdb: error initializing thread_db library.
Yes, twice.
Why is the host side looking in /lib for target libraries? Can I
control that? How?
Why is gdbserver on the target having trouble? I see I have correctly
delivered the thread_db library in /lib on the target, so what gives?
Any help or guidance would be greatly appreciated. I build my toolchain
with crosstools.

Global uninitialized variables should be located in BSS section of ELF.
Then somebody should initialize BSS at the start of a program. In user
space this is done by crt.* small objects written in assembler and
built-in to each application by gcc.
In kernel space this should be done by kernel itself. And I guess, this
is done. So, I don't see any reasons to initialize global variables and
thus to make kernel data segment bigger...

True, I added the check three times to emphasise the three different

This makes sense. Did you want to update the patch for those proposed
changes (You're more familiar with the code than I - I'm reluctant to
play too much with code unless I understand what it is doing)? I'd be
willing to test an updated patch.

I'm really not familiar with the complexities behind DMA
programming, especially when it comes to simplex devices so I'm
probably not in much of a position to finish up handling of simplex
devices.

I don't believe that it is possible to port BlueZ to the Windows
platform, but I also don't wanna keep you from trying it. Personally I
think it is easier to start from scratch and then offer the same
interfaces as BlueZ does for Linux.

It's a problem as hotplug runs from the kernel directly, with no stdin

No, udev contains "namedev" and "libsysfs". They are all built into one
udev binary.

Build udev with DEBUG=true and USE_LOG=true and show us what the debug
logs say when you run udev.

Only if those "compiler and other preprocessing tools" are normally
distributed with the O/S the executable runs on. If you create your own
compiler, and it's not "normally distributed", then you can't publish
source code in that language under the GPL without making the compiler

I'm surprised the sense messages don't show that it's a write to a write
protected disc (xx/27/zz, where xx == 0x07 or 0x05). However, it's even
more annoying to _not_ be able to write to a media because the kernel
thinks it knows better. In your fsck case you sort of get what you ask

If udev is built with klibc it will just assume that sysfs is mounted at
/sys.
Is there any reason you are not mounting sysfs at /sys? That's the
current convention.

Visually yes, they hurt to the sight ;-)
But unless somebody uses -std or -ansi, by default GCC
ignores trigraphs.

Ok thanks for the confimration. I will try to reproduce this with the
SuSE 8.2 compiler and track it down.

* GPL license and linux kernel modifications
From: "Bansh" @ 2004-01-27 16:25 UTC (permalink / raw)
To: linux-kernel
Hello!
I've got a question, which I can't resolve myself about linux kernel binary code. The problem is GPL license which tells us that:
----------- cut COPYING -----------
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
----------- cut COPYING -----------
It gives the possibility to not distribute compiler and other preprocessing tools.
It looks like one can make a preprocessor or even one's own compiler (with one's syntax) which will be used for kernel building. But it's not required to distribute this compiler. So I can distribute linux kernel source code modified this way but no one will be able to build it. Is it ok?
Such compiler/preprocessor can be really very tricky and can hide the modifications very much, thus allowing to hide proprietary know-how.

* MPC8xx SCC for sync. HDLC on 2.4 kernel
From: Jos Beck @ 2004-01-27 16:23 UTC (permalink / raw)
To: linuxppc-embedded
I am trying to build a synchronous HDLC driver for the SCC of the MPC850/860
under linux kernel 2.4.22
I have got one working on a 2.2.5 kernel and one buggy, async only, for the 2.4
kernels.
What would be the best approach: porting the 2.2.5 driver to the 2.4.x kernel or
digging into the driver (ehdlc.c by Rodolfo Giometti based on Dan Malek's
enet.c) to make it work for sync HDLC at high speeds?
Or an alternative?
Best regards,
Jos Beck
