Thanks Dirk, I was hoping you would reply as I've seen your posts about
rt-preempt on the davinci platform before.
Those links do help explain the background for the cmpxchg macros, and
all of those changes seem to have been integrated into the 2.6.26-rt1
patchset.
I'm still confused about why I was getting that error about
wrong_size_cmpxchg before though. Interestingly enough, if I compile
with CodeSourcery's toolchain, I don't get any linker errors with the
stock rt1 patch, but my ethernet doesn't work. On the other hand with
the Montavista toolchain, I need my hack to compile/link successfully,
but the kernel works fine once I do that.
Can you send us output of arm-...-gcc -v to get an idea what
toolchains you use? Can you try with CodeSourcery's 2007q3-51 ARM
GNU/Linux tool chain
http://www.codesourcery.com/gnu_toolchains/arm/portal/release313
?
This is known to build working kernels (if not using -Os). If you have
your ethernet issue with this, too, I would look for a code issue.
Thanks
Dirk
