So FPU code must always be locked against kernel preemption.
所以FPU代码必须始终被锁定,以防止内核抢占。
When the kernel is executing floating point instructions, the FPU state is not saved.
当内核在执行浮点指令时,FPU状态不被保存。
FPU mode is another case where the state of the CPU should be protected from preemption.
FPU模式是另外一种CPU应该被保护起来不被抢占的情形。
If preemption happens here, then upon reschedule, the FPU state is completely different from what was there before preemption.
如果这时发生了抢占,由于重新调度,FPU状态就会与抢占前完全不同。
The default rounding mode of the FPU is "Round toward nearest."
FPU 的默认舍入模式为“舍入为最接近的整数”。
