Hi All, I am seeking info about the following property that is in power.conf files on x86 and Sparc systems.
# This entry keeps removable media from being powered down unless the # console framebuffer and monitor are powered down # (See removable-media(9P)) # device-dependency-property removable-media /dev/fb I have never seen "device-dependency-property" used with anything other than "removable-media" and /dev/fb. It looks like it was originally designed just for removable-media with a dependency on /dev/fb. Could someone explain the implementation of this? The device driver can either set removable-media=1 or during a ddi_prop_create() pass in "removable-media". Then is it the power management framework that checks to see that when /dev/fb is powered down, then the removable-media can be powered down? How is HAL involved in this or /dev/fb? Is the driver property "removable-media" only used for power management and that device? I am trying to figure out if this device-dependency-property, which was implemented about a decade ago, is still being used and needed. Thanks for any help, Margot _______________________________________________ pm-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/pm-discuss
