[lkcd-devel] custom dump patch

[Haren M. <hb...@us...>]

Hello,
      This custom dump patch extends the crash dump mechanism (lkcd) to
allow different parts of memory to be selectively placed in a crash dump or
excluded from the dump. This patch is created against 2.4.17 kernel and the
current CVS lkcd 2.4 sources.  See the 'Custom Dump' document for the
complete explanation of  interfaces and the design changes that are needed
to implement this feature. Even though this document was posted on Dec16, I
am attaching it again in this e-mail. This document outlines the
modification of lkcd, lkcd_config command that is used to read user
requests and pass them to the kernel using 'dumpfs' virtual filesystem, and
lcrash tools. But the lkcd_config and lcrash tools modification will be
developed later. Hence, to use the custom dump patch, the user has to
create the 'dumpfs' filesystem entries for passing various user requests.
Please see the 'Custom dump Instructions' document that explains the
configuration of 'dumpfs' filesystem, various requests and filesystem
entries that will be created to pass these requests. Let me know your
comments/suggestions.

Thanks
Haren
