Hi everybody. A while ago, there was some disucssion about shrinking the size of the dump file on this mailing list. http://lists.osdl.org/pipermail/fastboot/2005-January/000981.html Re: [RFC] What is the proper interface between kernels.
I also think that it is necessary to make the size of the dump file smaller, in order to + make it easier to transfer the dump file from the system that failed to the system running analysis, and to + make kdump work faster. It now takes 74 seconds for making the dump file on a system with 5GB of memory. To solve these problems, we'd like to develop following 2 functions on kdump. o Partial dump The function which dumps only pages that a program for analyses (crash command etc.) requires. For reduction in dump file size and reduction in dump time. o Compression The function which compresses a dump file. For reduction in dump file size. Is there anybody developing similar features? We'd like to cooperate in development. Thanks Ken'ichi Ohmichi
