Extend the functionality of AMD Secure Processor (SP) driver by
providing an in-kernel API to submit commands to TEE ring buffer for
processing by Trusted OS running on AMD Secure Processor.
Following TEE commands are supported by Trusted OS:
* TEE_CMD_ID_LOAD_TA : Load Trusted Application (TA) b
Adds a PCI device entry for Raven Ridge. Raven Ridge is an APU with a
dedicated AMD Secure Processor having Trusted Execution Environment (TEE)
support. The TEE provides a secure environment for running Trusted
Applications (TAs) which implement security-sensitive parts of a feature.
This patch co
This is a preliminary patch for creating a generic PSP device driver
file, which will have support for both SEV and TEE (Trusted Execution
Environment) interface.
This patch does not introduce any new functionality, but simply renames
psp-dev.c and psp-dev.h files to sev-dev.c and sev-dev.h files
The goal of this patch series is to introduce TEE (Trusted Execution
Environment) interface support to AMD Secure Processor driver. The
TEE is a secure area of a processor which ensures that sensitive data
is stored, processed and protected in an isolated and trusted
environment. The Platform Secur
The PSP (Platform Security Processor) provides support for key management
commands in Secure Encrypted Virtualization (SEV) mode, along with
software-based Trusted Execution Environment (TEE) to enable third-party
Trusted Applications.
Therefore, introduce psp-dev.c and psp-dev.h files, which can
PSP can support both SEV and TEE interface. Therefore, move
SEV specific registers to a dedicated data structure.
TEE interface specific registers will be added in a later
patch.
