From 4515a5f786024fabf0bef4cf3d28adf5647e6e82 Mon Sep 17 00:00:00 2001 From: Daniel Henrique Barboza Date: Mon, 1 Mar 2021 09:41:33 -0300 Subject: qemu_timer.c: add timer_deadline_ms() helper The pSeries machine is using QEMUTimer internals to return the timeout in seconds for a timer object, in hw/ppc/spapr.c, function spapr_drc_unplug_timeout_remaining_sec(). Create a helper in qemu-timer.c to retrieve the deadline for a QEMUTimer object, in ms, to avoid exposing timer internals to the PPC code.
