Subject: [PATCH] MIPS: Octeon: add option to ignore PT_NOTE section
Some early Octeon bootloaders cannot process PT_NOTE program
headers as reported in numerous sections of the web, here is
an example http://www.spinics.net/lists/mips/msg37799.html
Loading usually fails with such an error ...
Error allocating memory for elf image!
The work around usually is to strip the .notes section by using
such a command $mips-gnu-strip -R .notes vmlinux -o fixed-vmlinux
It is expected that the vmlinux image got after compilation be
bootable. Add a Kconfig option to ignore the PT_NOTE section.
Do we really want this to be in the kernel? In my opinion, this is a
which distributions should be aware of, but not necessarily take
place here in
the kernel Makefiles.
You are right in one way. But as an OS vendor company we will definitely
include this patch in our distribution. This incident has been reported
many a times and its a pain to see the image not boot up, throw up an
error, with the user having to search the work around on the web. What
we are trying to do is save all that trouble. If it can be fixed why not
I don't care one way or another. We too (perhaps one and the same...)
provide kernels to our SDK customers with the patch applied.
An alternative approach would be to put the $(CROSS_COMPILE)strip
command into the arch/mips/Makefile.
I doubt that's any good, strip also removes debug symbols along with the
notes section and I am not aware of a specific command to strip just the
PT_NOTE section. Just these lines of code seem to get the job done
NOTES :text :note
+ NOTES :text
strip can be told to only strip a particular section, e.g:
$(TARGET_CROSS)strip -R .notes
like David, I prefer this option rather than modifying the linker script.
