在preempt_schedule和preempt_schedule_irq函数中,都有对preempt_count必须为零的判断和保护。也就是说,如果在进程中调了local_bh_disable(),那么在调local_bh_enable()之前,是不可能发生调度的,从而就保证了本cpu上的ksoftirqd线程和kworker(cmwq机制之前是keventd)线程都不会在local_bh_enable()之前得到执行。

Current Behavior I'm trying to dynamically set upstreams.tls.client_cert/client_key in stand-alone mode. I can't find a way to set the value via file lookup so I'm trying to set it via environment value. Whenever I set the value to the c...
If disabling UART1 8 via software, clear the IRQ Enable bit (MCR3) to zero before clearing FER 1. This is not an issue after reset because MCR3 is zero until it is written. Bit 2 When this bit is one, UART2 10 can be accessed at the address specified in the FAR. When this ...
