Plugin: PCI PSP — Platform Secure Processor


This plugin checks all information reported from the AMD Platform Secure processor into the operating system on select SOCs.

The lack of these sysfs files does NOT indicate the lack of these security features, it only indicates the lack of the ability to export it to the operating system.

The availability of the sysfs files indicates that the PSP supports exporting this information into the operating system.

External Interface Access

This plugin requires read only access to attributes located within /sys/bus/pci/devices/.
