GenWQE device nodes

Red Hat Enterprise Linux 9.2 LPAR mode z/VM guest

GenWQE user space components use device nodes to exchange data with the GenWQE device driver.

Red Hat® Enterprise Linux® 9.2 automatically loads the GenWQE device driver module when it is required. It also creates a device node of the form /dev/genwqe<n>_card for each available virtual acceleration card. <n> is an index number that identifies an individual virtual card. Node /dev/genwqe0_card is assigned to the first card that is detected, /dev/genwqe1_card to the second card, and so on.

Do not directly use these device nodes. The nodes are intended to be used by the user space components of the GenWQE hardware-accelerated zlib and by IBM® Java™.
