AFAIK we agreed on patches 1-4: the tickless run you did for me (rodolfo-14-tickless-1hz) had all four applied. If 1 and 2 alone are enough, could you put numbers for that in the commit message too? And for the UAPI, an RFC first please. :-) Ciao, Rodolfo -- GNU/Linux Solutions e-mail: giometti@enneenne.com Linux Device Driver giometti@linux.it Embedded Systems phone: +39 349 2432127 UNIX programming
