Hvcs is the server-side driver in some environments. I.e. a hvc console connects through the hypervisor to a hvcs in another partition. > If so, does this mean that I can take hvc_beat.c, modify it to make Freescale > hypervisor calls instead, and presto, I'm done? Yep, pretty much. It's real easy to write a new backend to hvc, I've got a couple for various bringup environments here as well. -Olof _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
