From 1a38416cea8ac801ae8f261074721f35317613dc Mon Sep 17 00:00:00 2001 From: David Shaohua Li Date: Wed, 23 Nov 2005 12:36:00 -0500 Subject: [ACPI] SMP S3 resume: evaluate _WAK after INIT On SMP resume from S3, we reset (INIT) the non-boot processors to boot them cleanly. But the BIOS needs to execute _WAK after INIT in order to properly initialized these processors upon resume. http://bugzilla.kernel.org/show_bug.cgi?id=5651 Signed-off-by: David Shaohua Li Signed-off-by: Len Brown --- kernel/power/main.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'kernel/power') diff --git a/kernel/power/main.c b/kernel/power/main.c index d253f3a..9cb235c 100644 --- a/kernel/power/main.c +++ b/kernel/power/main.c @@ -133,10 +133,10 @@ static int suspend_enter(suspend_state_t state) static void suspend_finish(suspend_state_t state) { device_resume(); - if (pm_ops && pm_ops->finish) - pm_ops->finish(state); thaw_processes(); enable_nonboot_cpus(); + if (pm_ops && pm_ops->finish) + pm_ops->finish(state); pm_restore_console(); } -- cgit v1.1 From 729b4d4ce1982c52040bbf22d6711cdf8db07ad8 Mon Sep 17 00:00:00 2001 From: Alexey Starikovskiy Date: Thu, 1 Dec 2005 04:29:00 -0500 Subject: [ACPI] fix reboot upon suspend-to-disk http://bugzilla.kernel.org/show_bug.cgi?id=4320 Signed-off-by: Alexey Starikovskiy Acked-by: Pavel Machek Signed-off-by: Len Brown --- kernel/power/disk.c | 9 +-------- 1 file changed, 1 insertion(+), 8 deletions(-) (limited to 'kernel/power') diff --git a/kernel/power/disk.c b/kernel/power/disk.c index 027322a..f2cd279 100644 --- a/kernel/power/disk.c +++ b/kernel/power/disk.c @@ -52,7 +52,7 @@ static void power_down(suspend_disk_method_t mode) switch(mode) { case PM_DISK_PLATFORM: - kernel_power_off_prepare(); + kernel_shutdown_prepare(SYSTEM_SUSPEND_DISK); error = pm_ops->enter(PM_SUSPEND_DISK); break; case PM_DISK_SHUTDOWN: @@ -119,13 +119,6 @@ static int prepare_processes(void) goto thaw; } - if (pm_disk_mode == PM_DISK_PLATFORM) { - if (pm_ops && pm_ops->prepare) { - if ((error = pm_ops->prepare(PM_SUSPEND_DISK))) - goto thaw; - } - } - /* Free memory before shutting down devices. */ free_some_memory(); return 0; -- cgit v1.1
