[OE-core] [PATCH] rng-tools: disable the CPU affinity mask

2021-05-09 Thread Yu, Mingli
From: Mingli Yu For the jitter entropy source, each task thread will create an internal counter timer thread when the system clock resolution is under 5MHz. But it will introduce high cpu usage for a long time and also make random data generate too slow if sets the CPU affinity mask of the
