Hello,
I am trying to build a custom kernel 2.6.24 from ubuntu with xen dom0
support.
Does Xen support a tickless system (CONFIG_TICK_ONESHOT=y) and the
realtime features of this kernel (CONFIG_PREEMPT=Y instead of
CONFIG_PREEMP_VOLUNTARY)?
Everytime, I set these options while configuring the kernel, the two
settings are not regarded during kernel compilation.
I also tried to build the kernel 2.6.27 from OpenSuse 11. The behaviour
is similar. If I choose xen-compatible=y in menu entry "Subarchitecure
Type", then the tickless system and CONFIG_PREEMPT options can't be set
any more.
So I wonder if Xen supports these features.
Thanks in advance,
Thomas
