Freescale Semiconductor

1Overview

The SEC2 device driver manages the operation of the SEC 2.0

commonly instantiated into PowerQUICC processors. It is a fully

functional component, meant to serve as an example of application

interaction with the SEC2 core.

The driver is coded in ANSI C. In it’s design, an attempt has been

made to write a device driver that is as operating system agnostic

as practical. Where necessary, operating system dependencies are

identified and Section 8, “Porting” addresses them.

Testing has been accomplished on VxWorks 5.5 and LinuxPPC

using kernel version 2.4.27.

Application interfaces to this driver are implemented through the

ioctl() function call. Requests made through this interface can

be broken down into specific components, including

miscellaneous requests and process requests. The miscellaneous

requests are any requests not related to the direct processing of

data by the SEC2 core.

Process requests comprise the majority of the requests and all are

executed using the same

ioctl() access point. Structures needed

to compose these requests are described in detail in Section 3.3.6,

“Process Request Structures.”

Throughout the document, the acronyms CHA (crypto hardware

accelerator) and EU (execution unit) are used interchangeably.
