ppc4xx is 32bit RISC processor and AFAIK, currently crash dump works only for ppc64. At least I am not aware of anybody working on it. > I'm asking because of collisions in the sysrq key space. > Crashdump uses sysrq-C (if CONFIG_KEXEC=y; should that > actually be if CONFIG_CRASH_DUMP=y ?). > No. The crashing kernel might not have CONFIG_CRASH_DUMP enabled. This is common when a separate custom kernel is being built to capture the dump. CONFIG_CRASH_DUMP needs to be enabled only if a kernel is used for dump capture purposes. Hence, sysrc-C needs to remain under CONFIG_KEXEC. > There is an IBM EMAC net driver that also uses sysrq-C, > but it is for PPC 4xx platforms only. > > So are these sufficiently mutually exclusive? at least > for now? > I think so that these are mutually exclusive, at least for now.
