Re: utrace support on ARM

2011-04-22 Thread Mark Wielaard 

 utrace per se has no machine-dependent code. It requires modern
 support for machine dependencies in generic kernel code,
 i.e. user_regset and tracehook. The ARM kernel has a tiny
 subset of those, but not enough to be useful.
 Long ago I did 98% of the work for implementing user_regset
 and tracehook support for ARM and posted it

This is the patch set Roland refers to
if someone wants to help push arm forward:

Cheers,

Mark

Thanks

I will see if I can interest people in TI and Linaro. I will need a good 
story... ;-)

It is kernel port modernization work that nearly every other platform has
done by now.
