Description: Display fw status registers content
|
||
|
|
|
||
|
|
The ME FW writes its status information into fw status
|
||
|
|
registers for BIOS and OS to monitor fw health.
|
||
|
|
|
||
|
|
The register contains running state, power management
|
||
|
|
state, error codes, and others. The way the registers
|
||
|
|
are decoded depends on PCH or SoC generation.
|
||
|
|
Also number of registers varies between 1 and 6
|
||
|
|
depending on generation.
