Name of Document Author/Supplier: Author: Garrett D'Amore 1.3 Date of This Document: 13 November, 2009 4. Technical Description EOF of pcmciad and pem kernel driver With the removal of pcmem and pcram, investigation shows that the pcmciad daemon only performs functions which are trivially replaceable. Specifically, devfsadm already handles the functionality for pcata disks, and the autopush of ldterm and ttcompat on pcser can be handled by adding a single line to /etc/iu.ap. In theory pcmciad could support other kinds of pcmcia devices via shared object interface, but this interface was Consolidation Private, and was never used. Furthermore, it looks extraordinarily unlikely that it will be used in the future -- such functionality is also available via devfsadm plugins should a need for such functionality with pcmcia cards ever be found in the future. Finally, the "pem" pseudo driver existed solely to provide PCMCIA event notifications to the pcmciad daemon. None of this functionality was ever "user accessible" or documented (other than the fact that it "existed"). Therefore we propose to simply remove it without notice. This case records this intent. 6.
