linux-toradex.git/arch/riscv/kernel/asm-offsets.c, branch v5.0 Linux kernel for Apalis and Colibri modules RISC-V: Add _TIF_NEED_RESCHED check for kernel thread when CONFIG_PREEMPT=y 2019-01-23T20:56:19+00:00 Vincent Chen vincentc@andestech.com 2019-01-03T03:32:33+00:00 99fd6e875d0c24448a5e2c241422a691be46b241 The cond_resched() can be used to yield the CPU resource if CONFIG_PREEMPT is not defined. Otherwise, cond_resched() is a dummy function. In order to avoid kernel thread occupying entire CPU, when CONFIG_PREEMPT=y, the kernel thread needs to follow the rescheduling mechanism like a user thread.
