From c4c4688f72e638708e5f6b5c259699de82a36fec Mon Sep 17 00:00:00 2001 From: Cliff Wickman Date: Fri, 3 Apr 2009 08:34:32 -0500 Subject: x86: UV BAU messaging timeouts This patch replaces a 'nop' uv_enable_timeouts() in the UV TLB shootdown code. (somehow, long ago that function got eviscerated) If any cpu in the destination node does not get interrupted by the message and post completion in a reasonable time the hardware should respond to the sender with an error. This function enables such timeouts. Tested on the UV hardware simulator.
