[S390] ETR support. 2007-02-05T20:18:19+00:00 Martin Schwidefsky schwidefsky@de.ibm.com 2007-02-05T20:18:19+00:00 d54853ef8cb17296ac7bce9c77430fb7c80532d0 This patch adds support for clock synchronization to an external time reference (ETR). The external time reference sends an oscillator signal and a synchronization signal every 2^20 microseconds to keep the TOD clocks of all connected servers in sync. For availability two ETR units can be connected to a machine. If the clock deviates for more than the sync-check tolerance all cpus get a machine check that indicates that the clock is out of sync. For the lovely details how to get the clock back in sync see the code below. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
