Subject: [PATCH 00/10] Add dynamic boost control support
Date: Thu, 20 Apr 2023 11:31:28 -0500 [thread overview]
Message-ID: <20230420163140.14940-1-mario.limonciello@amd.com> (raw)
Dynamic boost control is a feature of some SoCs that allows
an authenticated entity to send commands to the security processor
to control certain SOC characteristics with the intention to improve
performance.
This is implemented via a mechanism that a userspace application would
authenticate using a nonce and key exchange over an IOCTL interface.
After authentication is complete an application can exchange signed
messages with the security processor and both ends can validate the
data transmitted.
This series includes a test suite that can be run on real hardware
to ensure that the communication works as expected. This can also be
used for an application to model the communication path.
Two sysfs files are introduced for reading the PSP bootloader version
as well as TEE version which can be useful data points for debugging
communication problems.
