I wanted to mention, along these lines, that netbsd has a command which can program the disk controller to enter "idle" or "standby" mode after a number of seconds. The command is "atactl". I looked at how this is done. It's using a set of controller commands which apparently aren't supported under FreeBSD. The controller commands are: #define WDCC_IDENTIFY 0xec /* read parameters from controller */ #define SET_FEATURES 0xef /* set features */ #define WDCC_IDLE 0xe3 /* set idle timer & enter idle mode */ #define WDCC_IDLE_IMMED 0xe1 /* enter idle mode */ #define WDCC_SLEEP 0xe6 /* enter sleep mode */ #define WDCC_STANDBY 0xe2 /* set standby timer & enter standby mode */ #define WDCC_STANDBY_IMMED 0xe0 /* enter standby mode */ #define WDCC_CHECK_PWR 0xe5 /* check power mode */ and these are not even *defined* in the FreeBSD files. Is there any chance of getting this supported under FreeBSD? /raj To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
