Installing the GenWQE hardware-accelerated zlib

Ubuntu 22.04 LTS LPAR mode z/VM guest

Install the libzadc4 and genwqe-tools packages that are included in Ubuntu Server 22.04 LTS with the apt command.

To install the genwqe-tools package, issue:
apt install genwqe-tools
This command automatically installs the required libzadc4 library.

The libzadc4 package includes the user space components of the GenWQE hardware-accelerated zlib.

The genwqe-tools package provides the following tools:
  • genwqe_gzip and genwqe_gunzip, which are GenWQE versions of gzip and gunzip.

    These tools can be used for most purposes, but they do not implement all of the more unusual options of their common code counterparts. See the man pages to find out which options are supported.

  • genwqe_echo, a tool to confirm the availability of accelerator hardware through the GenWQE accelerated zlib.
