Detailed Description

LCM memory scrubbing/exception handling functions (for non-rad750).

CVS $Id: LCM_scrubArch.c.xx-xxx-xxx,v 1.2 2008/10/30 01:12:49 apw Exp $

LCM_scrubArch.c.xx-xxx-xxx handles the memory scrubbing and PCI/memory error exception handling sub-functions of LCM. Or rather it doesn't. This implementation is for all architectures other than rad750. This is complete fakery.

Function Documentation

void LCM_scrubMemAuto (  LCM_Control *  ctl  )

Architecture specific implementation of LLCMSCRUBRUN command. LCM_scrubMemAuto() implements the LLCMSCRUBRUN command for non-rad750.

unsigned int LCM_scrubSurom (  LCM_SuromError *  rom, unsigned int *  hcs, unsigned int *  bcs )

Scrub through SUROM contents to check integrity. Return values: LCM_SUCCESS  Always LCM_scrubSurom() performs memory reads through the rad750 SUROM to check for integrity. For all architectures except rad750, there is no SUROM (at least, not in the sense that applies to the rad750 SUROM). Nevetheless, try for some fidelity (even if this only ever reports that scrubbing induced no memory errors).

unsigned int LCM_scrubTaskInitialize (  LCM_Control *  ctl  )

One-time call in LCM task context to start the scrub sub-function. Parameters: ctl  (in) LCM control block LCM_scrubTaskInitialize() is run once only in the LCM task context to do any final initialization required by the scrub/exception handling subfunction. For all architectures except rad750, scrubbing is not available. Nevetheless, try for some fidelity with the scrub timer logic.
