Subject: [PATCH] Inhibit NMI watchdog when Alt-SysRq-T operation is underway.
Date: Mon, 9 Jul 2007 10:02:42 -0400 [thread overview]
Message-ID: <20070709140242.GA18098@andromeda.dapyr.net> (raw)
On large memory configuration with not so fast CPUs the NMI watchdog
is triggered when memory addresses are being gathered and printed.
The code paths for Alt-SysRq-t are sprinkled with touch_nmi_watchdog
in various places but not in this routine (or in the loop that utilizes
this function). The patch has been tested for regression on large CPU+memory
configuration (128 logical CPUs + 224 GB) and 1,2,4,16-CPU sockets with various
memory sizes (1,2,4,6,20).
