Hi, Dan,
It still doesn't work, and could you give more detail
instructions about steps to run on ski simulator and real hardware.
Are the steps you described upon zx1_defconfig only adapts to
zx1 machine, or also works for ski? If only for zx1 machine, why need to
add hpsim_cons like stuff for CONFIG_XEN? If also for ski, I always
encountered "Can't open root device" problem.
I also tried to copy sim_defconfig, and there's no output after
"Freeing unused kernel memory: 192kB freed" but the keyboard can work.
Before reaching this point, at least I need to change something for
para-xenlinux:
1. Comment following line in arch/ia64/Makefile:
#drivers-$(CONFIG_XEN) += arch/ia64/hp/sim/
Or else the compilation will fail due to double
inclusion
2. Comment arch/ia64/kernel/setup.c:
static inline int __init
early_console_setup (char *cmdline)
{
#if 0
//#ifdef CONFIG_XEN
extern struct console hpsim_cons;
register_console(&hpsim_cons);
return 0;
#else
Or else the hpsim_cons is registered twice and then xenlinux
will search console list and output same string repeatedly for ever:
Linux version 2.6.11 (gcc version 3.2.3 20030502 (Red Hat Linux
3.2.3-20)) #7 SMP Sun May 15 18:30:58 PDT 2005
But after all above done, it still can't reach user prompt.
Since I'm not familiar with ski simulator environment, could you give a
step-by-step instruction for run on ski? :)
Thanks a lot,
Kevin
