UACCE adds the hardware error isolation feature. To improve service reliability, some uacce devices that frequently encounter hardware errors are isolated. Therefore, this feature is added. Users can configure the hardware error threshold by 'isolate_strategy' sysfs node. The user space can get the device isolated state by 'isolate' sysfs node. If the number of device errors exceeds the configured error threshold, the device will be isolated. It means the uacce device is unavailable.
