Indeed, but that's not the point. A defconfig file should be the result
of running one of the various configuration targets; yours are
hand-patched. If you run the defconfig target, it will copy the config
file and run oldconfig, thus resulting in a different configuration file
(because options may now be gone and hence disabled) than what was in
the defconfig, and thus people may come to the wrong conclusion that if
a driver is enabled in a defconfig file, it will be built.

Found it!
Sorry, It was my error.
I have few #ifdef-s to determine HZ value depend on selected board,
but in some (for example itimer.c and timer.c) files <linux/config.h> is
NOT included
before <asm/param.h> is included sowhere in the dark....
So some code was compiled with default value

[-- Attachment #1: Type: text/plain, Size: 1771 bytes --]
I have 2.4.25 kernel from denx.de and latest uClibc running on mpc8248.
I'm trying to change HZ value, but still have strange results with
simple test
Recompiling whole uClibc does not change the results.
What could be wrong?

See the U-Boot source code. U-Boot itself is just such a bare-silicon
application program (a pretty complex one, though). Also see the
examples/ directory which contains code for several simple standalone
applications within the U-Boot context.
Note that you will have to understand how the linker works, and know
exactly what you are doing.

Wolfgang Denk

I will say you if I find anything

* [PATCH] powerpc: Experimental support for new G5 Macs
From: Benjamin Herrenschmidt @ 2005-12-13 7:17 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc64-dev, linuxppc-dev list
This adds some very basic support for the new machines, including the
Quad G5 (tested), and other new dual core based machines and iMac G5
iSight (untested). This is still experimental ! If you have more than
2Gb of RAM, you MUST boot with mem=2G to limit it as the iommu/DART code
for the new bridge chip is not there yet (hopefully tomorrow). There is
no thermal control yet, there is no proper handing of MSIs, etc.. but it
boots, I have all 4 cores up on my machine.

* [PATCH] nvidiafb: Fixes for new G5
From: Benjamin Herrenschmidt @ 2005-12-13 7:12 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc64-dev, linuxppc-dev list
This patch is not for inclusion in anything but powerpc git tree and
only temporarily as it's being dealt with separately for upstream merge
and is already in -mm. It fixes an issue in nvidiafb for the the G5s.

* [PATCH] PCI: Export pci_cfg_space_size
From: Benjamin Herrenschmidt @ 2005-12-13 7:09 UTC (permalink / raw)
To: Greg KH, Paul Mackerras; +Cc: linuxppc64-dev, linux-pci, linuxppc-dev list
The powerpc PCI code sets up the PCI tree without doing config space
accesses in most cases, from the firmware tree. However, it still wants
to call pci_cfg_space_size() under some conditions, thus it needs to
be made non-static (though I don't see a point to export it to modules).
Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Greg: I don't remember if I already sent you that patch or not, if not,
then heh, here it is :) The powerpc patch that requires this one will be
going next to the powerpc git tree and -mm, with a 2.6.16 target. Let me
know if there is any objection.
Paul: You need that for the new G5 support patch that I'm sending next.

* [PATCH] powerpc: Remove device_node addrs/n_addr
From: Benjamin Herrenschmidt @ 2005-12-13 7:01 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc64-dev, linuxppc-dev list
The pre-parsed addrs/n_addrs fields in struct device_node are finally
gone. Remove the dodgy heuristics that did that parsing at boot and
remove the fields themselves since we now have a good replacement with
the new OF parsing code. This patch also fixes a bunch of drivers to use
the new code instead, so that at least pmac32, pseries, iseries and g5
defconfigs build.

Hi All,
I am having custom board which is similar to MPC8260ADS board. I want to
port linux on this board. I am having TRACE32 debugger.
When i put breakpoint on load_up_mmu, it won't stop at this point. It
shows running in the status bar and when i give break, it goes to panic
symbol and it hangs there. I cannot proceed further. Then i have to reload
the cmm file again.
Can any one tell me what and where is the problem.
I am using Linux-2.4.25 from denx and my boards memory map is
SDRAM 128MB(0x00000000) and Flash 1MB(starts from 0x30000000).
Thanks in advance.
best regards

thanks a lot.Would you give me more inf,please?
There were a test.c.
When we use "ppc_6xx-gcc -o test test.c",we can get a "test" which can running in Linux.
How can we get a "test" which can running in bareboard and be debuged using the BDI2000?

you can modify serial.c:

{
my_uart_init();
....
....
}
add my_uart_init(), it init OR and BR where your board uart use,
and fill rs_table with IRQ and IOBASE.

No, CONFIG_BROKEN=y in a defconfig file is a bug.
Either the defconfig doesn't use BROKEN code in which case it's simply
wrong, or it's a wrong workaround (as in the CONFIG_MTD_SHARP case) for
a wrong BROKEN dependency.
And it's a dangerous workaround:
Consider e.g. that "both marked as obsolete and BROKEN" are the best
candidates for "remove obsolete code" cleanups - and there goes your
driver to /dev/null ...

I'm not sure about 2.6.12-rc1, but you can try GIT tree/patches at
http://kernel.ebshome.net.
Hint: you can assume that in addition to emac_3-2.6-28.diff, there are
also emac_3-2.6-NN.diff (NN < 28) on my website which were made for
earlier kernel versions :).
Alternatively, you can backport all relevant stuff from current 2.6 or
you can pay someone to do this for you.

* ibm emac driver update
From: Simon Haynes @ 2005-12-12 17:26 UTC (permalink / raw)
To: linuxppc-embedded
I am running a Ebony board with linux-2.6.12-rc1 and I amd having intermittent
network problems. Having searched the archives it would seem that the driver
for the IBM EMAC is buggy ?
I have tried to patch my kernel with
http://kernel.ebsname.net/emac/4xx_napi_emac.diff
I believe this is almost a total driver re-write. Is this correct ?
After having a couple of problems applying the patch, Kconfig and
ibm_emac_core.c. I fixed up the original code and applied the patch.
On compilation the build fails with missing references to kzalloc,
which I guess I could easily fix with kmalloc and memset.
However there is also an undefined field, dcr_base, in the ocp_func_mal_data
structure. This structure appears to be defined in include/asm/ibm_ocp.h and
this file does not appear to be changed by the patch. I guess this patch is
for a later kernel.
Can anyone point me in the direction of a suitable patch for this kernel ?
Many Thanks
Simon.
