Detailed Description

Host request to setup/release FW logging.

Messages of this type are processed by the logging handler.

For SETUP sub-command, buffer_addr_lo/hi specify the host DMA buffer IOVA and buffer_size specifies the size in bytes. For RELEASE sub-command, only subcmd is used - other fields are ignored.
