Abstract: The XScale initiative supported by Intel is a development environment supporting many  families of processors used for embedded applications in products  in Cellular, Handheld, I/O Processors and Network Processors. OpenPegasus needs to support this environment in order to enable these products to be  incorporated into the OpenPegasus family of managed devices.


Definition of the Problem

In order to support the XScale family of processors a platform file must be added to OpenPegasus.

Proposed Solution

Add the file platform_LINUX_XSCALE_GNU.mak to the pegasus/mak directory immediately to incorporate it into the 2.5 release.

Platform_LINUX_XSCALE_GNU file.

# Configuration parameters for the XScale architecture.

include $(ROOT)/mak/config-linux.mak

ARCHITECTURE = iX86
RPATH=-Xlinker -rpath-link -Xlinker

Rationale

<>It was first thought that one of the existing LINUX platform files could be used to support XScale. It recently became self evident that this approach was not going to be architecturally acceptable. The XScale environment has a few peculiarities dictating that it requires it's own platform file as the cleanest implementation to avoid corrupting an existing platform file with numerous conditional compile statements controlled by a set of configuration variables associated with the XScale, processors, compilers and operating system. 

Schedule

Add the XScale Platform file for the 2.5 release.
The file is already developed, tested and in use. It can be added to Pegasus within 3 days of this PEP's approval.

There is minimal risk to this since this platform file will be used only by the users of this paltform.  This change does not change any other files in Pegasus. 

This platform is being used by Adaptec today.

Discussion

TBD
