Subject: [PATCH 0/4] Communication Interface to NXP secure-enclave HW IP like Edgelock Enclave
Date: Fri, 10 May 2024 18:57:26 +0530 [thread overview]
Message-ID: <20240510-imx-se-if-v1-0-27c5a674916d@nxp.com> (raw)
Hardware interface of the NXP Secure Enclave HW IP(s) like EdgeLock Enclave,
V2X, SHE etc, is based on the Messaging Unit module that enables processing
elements like ARMv8 core, RISC V core, within the SoC to communicate and
coordinate by passing messages (e.g., data, status and control) through
these interfaces.
The NXP i.MX secure enclaves hardware interface kernel driver, is specifically
targeted for use between application core and NXP secure-enclave(s) HW. It allows
to send/receive messages to/from the secure-enclave.
Patch-set adds the kernel driver for communication interface to secure-enclave,
for exchanging messages with NXP secure enclave HW IP(s) like EdgeLock Enclave,
both from:
- User-Space Applications via character driver.
- Kernel-space, used by kernel management layers like DM-Crypt.
