Hello all,
As most of you know, I'm trying to move a bunch of Linux
initialization code into early userspace, "klibc". This is now in
2.6.17-rc4-mm1, and I've gotten a sparc64-related bug report,
specifially related to the following:
[arch/sparc64/kernel/setup.c]
#ifdef CONFIG_IP_PNP
if (!ic_set_manually) {
int chosen = prom_finddevice ("/chosen");
u32 cl, sv, gw;
cl = prom_getintdefault (chosen, "client-ip", 0);
sv = prom_getintdefault (chosen, "server-ip", 0);
gw = prom_getintdefault (chosen, "gateway-ip", 0);
if (cl && sv) {
ic_myaddr = cl;
ic_servaddr = sv;
if (gw)
ic_gateway = gw;
#if defined(CONFIG_IP_PNP_BOOTP) || defined(CONFIG_IP_PNP_RARP)
ic_proto_enabled = 0;
#endif
}
}
#endif
Is there a way to get that information from userspace, and if not,
should there be a general way to do it or an ad hoc solution? It sort
of looks like arch/sparc64/prom describes a form of filesystem, but I
don't see any obvious userspace interface.
