Although it's not hard it's a bit fiddly to work out what the bounds of the kernel stack should be based on the kstack value. To make life easier and "kstack_base" which is the base (lowest address) of the kernel stack, eg: kstack = 0xc0000000f1a7be30 (0x258) kstack_base = 0xc0000000f1a78000 Signed-off-by: Michael Ellerman --- diff --git a/arch/powerpc/xmon/xmon.c b/arch/powerpc/xmon/xmon.c index 2e2320edb96b..83e7faf5b3d3 100644 --- a/arch/powerpc/xmon/xmon.c +++ b/arch/powerpc/xmon/xmon.c @@ -2384,6 +2384,7 @@ static void dump_one_paca(int cpu) #endif DUMP(p, __current, "p"); DUMP(p, kstack, "lx"); + printf(" kstack_base = 0x%016lx\n", p->kstack & ~(THREAD_SIZE - 1)); DUMP(p, stab_rr, "lx"); DUMP(p, saved_r1, "lx"); DUMP(p, trap_save, "x");
