v19 v20 59 59 * the '''critical''' trip point should not be exceeded to avoid damaging the CPU and as such when this trip point is reached the Linux shutdown function is called to attempt to gracefully shut down the OS. The default implementation will end up simply resetting the board but before that occurs a usermode helper will exec /sbin/poweroff which the user could implement to do whatever they choose (ie, sync filesystems, use GSC sleep for 'x' seconds, etc). 60 60 * the thresholds for the driver can be adjusted in userspace (see above) 61 * Gateworks has [http://thread.gmane.org/gmane.linux.ports.arm.kernel/409671/focus=411988 <span class="icon">​</span>an upstream Linux patch pending approval]that will set the initial setpoints according to the temperature grade of the CPU determined via eFUSE registers. This patch will eventually be rolled into our various kernel support.61 * Gateworks has an upstream Linux patch pending approval that will set the initial setpoints according to the temperature grade of the CPU determined via eFUSE registers.
