21 | Description: Display fw status registers content | |
22 | ||
23 | The ME FW writes its status information into fw status | |
24 | registers for BIOS and OS to monitor fw health. | |
25 | ||
26 | The register contains running state, power management | |
27 | state, error codes, and others. The way the registers | |
28 | are decoded depends on PCH or SoC generation. | |
29 | Also number of registers varies between 1 and 6 | |
30 | depending on generation. | |
