As the manpage of shutdown shows: -r Reboot after shutdown. -H Halt action is to halt or drop into boot monitor on systems that support it. -P Halt action is to turn off the power. and in the real world, some machines(e.g. NAS) did not provide a power button and the shutdown works as reset, so, we need to provide a mechanism to let the users turn off the power safely without breaking the system, such a mechanism is "halt", which only put the system into a dead loop or a power-save mode and print some information to the screen to tell the users to turn off the power safely. $ shutdown -hH now /* loongson_halt, not turn off the power */ $ shutdown -hP now /* loongson_poweroff, work as poweroff */ Signed-off-by: Wu Zhangjin Tested-by: Liu Shiwei Cc: Liu Shiwei Cc: linux-mips Patchwork: http://patchwork.linux-mips.org/patch/883/ Signed-off-by: Ralf Baechle --- arch/mips/loongson/common/reset.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) (limited to 'arch/mips/loongson') diff --git a/arch/mips/loongson/common/reset.c b/arch/mips/loongson/common/reset.c index 33dff188b4de..4bd9c18b07a5 100644 --- a/arch/mips/loongson/common/reset.c +++ b/arch/mips/loongson/common/reset.c @@ -25,17 +25,26 @@ static void loongson_restart(char *command) ((void (*)(void))ioremap_nocache(LOONGSON_BOOT_BASE, 4)) (); } -static void loongson_halt(void) +static void loongson_poweroff(void) { mach_prepare_shutdown(); unreachable(); } +static void loongson_halt(void) +{ + pr_notice("\n\n** You can safely turn off the power now **\n\n"); + while (1) { + if (cpu_wait) + cpu_wait(); + } +} + static int __init mips_reboot_setup(void) { _machine_restart = loongson_restart; _machine_halt = loongson_halt; - pm_power_off = loongson_halt; + pm_power_off = loongson_poweroff; return 0; } -- cgit v1.2.3 From 896508705561bea24656680cdaf3b4095c4d7473 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Sat, 27 Feb 2010 12:53:38 +0100 Subject: MIPS: i8259: Convert IRQ controller lock to raw spinlock.
