This size is a configured integer value, which is the 28 number of threshold for hardware errors occurred in one hour. The default is 0. 29 0 means never isolate the device. The maximum value is 65535. You can write 30 a number of threshold based on your hardware. 31 32 What: /sys/class/uacce/<dev_name>/isolate 33 Date: Nov 2022 34 KernelVersion: 6.1 35 Contact: linux-accelerators@lists.ozlabs.org 36 Description: (R) A sysfs node that read the device isolated state. The value 1 37 means the device is unavailable. The 0 means the device is 38 available. 39 40 What: /sys/class/uacce/<dev_name>/algorithms 41 Date: Feb 2020 42 KernelVersion: 5.7 43 Contact: linux-accelerators@lists.ozlabs.org 44 Description: Algorithms supported by this accelerator, separated by new line. 45 Can be any string and up to userspace to parse. 46 47 What: /sys/class/uacce/<dev_name>/region_mmio_size 48 Date: Feb 2020 49 KernelVersion: 5.7 50 Contact: linux-accelerators@lists.ozlabs.org 51 Description: Size (bytes) of mmio region queue file 52 53 What: /sys/class/uacce/<dev_name>/region_dus_size 54 Date: Feb 2020 55 KernelVersion: 5.7 56 Contact: linux-accelerators@lists.ozlabs.org 57 Description: Size (bytes) of dus region queue file
