Whether it's realistic scenario and whether it's worth caching the thresholds in the kernel I hope Iwona can clarify. In my current opinion the added complexity isn't worth it, the PECI operation needs to be reliable enough anyway for BMC to monitor at least the CPU temperatures once a second to feed this essential data to the cooling fans control loop. And if we can read CPU temperatures we can also read DIMM thresholds when we need them and worse case retry a few times while starting up the daemon. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercerpav@xxxxxxxxx
