^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) This driver implements sensor reading support for the energy and power meters
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) available on various IBM System X hardware through the BMC.  All sensor banks
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) will be exported as platform devices; this driver can talk to both v1 and v2
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) interfaces.  This driver is completely separate from the older ibmpex driver.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) The v1 AEM interface has a simple set of features to monitor energy use.  There
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) is a register that displays an estimate of raw energy consumption since the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) last BMC reset, and a power sensor that returns average power use over a
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) configurable interval.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) The v2 AEM interface is a bit more sophisticated, being able to present a wider
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) range of energy and power use registers, the power cap as set by the AEM
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) software, and temperature sensors.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) Special Features
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) ----------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) The "power_cap" value displays the current system power cap, as set by the AEM
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) software.  Setting the power cap from the host is not currently supported.
