<p class=MsoNormal>Hi<o:p></o:p></p>
<p class=MsoNormal>In the latest arm kernel, I find that smp_twd.c has
implemented local timer for cortex a9 MPcore. In the spec, there is global
timer that shared by all MPcore. I did not find any implements in the arm
kernel. What is the strategy of using these two kinds of timer? I find that
some SOCs have additional timer which is not the local timer or global timer in
MPcore. Then what is the strategy of using this kind of timer with local timer
and global timer in the kernel? Thanks.<o:p></o:p></p>
