/* Opcode for management ioctl

 *

 * HW_IP_INFO         - Receive information about different IP blocks in the

 *                      device.

 * HL_INFO_HW_EVENTS  - Receive an array describing how many times each event

 *                      occurred since the last hard reset.

 * HL_INFO_DRAM_USAGE - Retrieve the dram usage inside the device and of the

 *                      specific context. This is relevant only for GOYA device.

 * HL_INFO_HW_IDLE    - Retrieve information about the idle status of each

 *                      internal engine.

 * HL_INFO_DEVICE_STATUS - Retrieve the device's status. This opcode doesn't

 *                         require an open context.
