Commit af391b1 ("arm64: kernel: rename __cpu_suspend to keep it aligned with arm") renamed cpu_suspend() to arm_cpuidle_suspend(), but forgot to update the kerneldoc header. Fixes: af391b1 ("arm64: kernel: rename __cpu_suspend to keep it aligned with arm") Signed-off-by: Gee...
启动cpu则不是进入halt,而是执行一些列操作将快照映像写入磁盘,最后调用power_down关闭电源,这个操作是由pm_ops->enter(PM_SUSPEND_DISK)完成的,这就提供了一个灵活的回调函数机制,将操作策略和执行机制分离,我们可以实现acpi的pm_ops,还可以实现apm的pm_ops,但是不管采用哪一种电源管理,上面说的执行机制是不会变...
因为小内存机器往往比较便宜,可能年付就是 $5 样子,所以厂家都会限制 CPU 和 磁盘IO ,如果超过了就会被 suspend,这是随随便便的事情蛤,而且有些主机商对于 suspend 都是不给予退款的。 所以我们可以借助一些软件来限制 CPU 的使用率和 IO。 还有千万不要用跑分软件跑分,不然准玩完。
It is incorrect to set the cpufreq syscore shutdown callback pointer to cpufreq_suspend(), because that function cannot be run in the syscore stage of system shutdown for two reasons: (a) it may attempt to carry out actions depending on devices that have already been shut down at that ...
I have to put my device into a very deep low power mode from Linux 2.6.38 and therefore, it's necessary to suspend all components, including CPU und DDR2. What I found out so far is that I have to copy the core assembler function into the processor's internal memory and execute it...
