From 4b214a0c7720bfcfaca936047a359f8859fc8424 Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Tue, 16 Jun 2009 10:30:47 +0200 Subject: [S390] pm: con3270 power management callbacks. Introduce the power management callbacks to the 3270 driver. On suspend the current 3270 view is deactivated and for non-console 3270 device the release callback is done. This disconnects the current tty / fullscreen application from the 3270 device. On resume the current view is reactivated, on the tty you get a fresh login. If the system panics before the 3270 device has been resumed, the ccw device for the 3270 console is reactivated with ccw_device_force_console.
