Re: [Xen-ia64-devel] [PATCH] xencomm_privcmd_sched_op

Tristan Gingold wrote:

  I have modified the build rule and some files, but some hypercall
seem to be unimplemented. like xencomm_mini_hypercall_hvm_op,
xencomm_mini_hypercall_xen_version.

Do you want me to implement them ?


 Yes, I hope to....

 I've attached the log of compiling PV-on-HVM driver, and
my modification for compiling them.

Thanks,
