Subject: For AMD SEV create /dev/psp.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=48fdf972e38a65fb33cc1ffee0413ee7b12989d8;p=openbsd

For AMD SEV create /dev/psp.

To call ioctl(2) for the platform security processor (PSP), vmd(8)
needs a device file.  It is currently linked to the cryptographic
co-processor ccp(4).  We may split this into a separate psp(4)
device.
