Building a kernel with the GenWQE device driver

6.10 LPAR mode z/VM guest

Control the build options for the GenWQE device driver through the kernel configuration menu.

Kernel builders: This information is intended for those who want to build their own kernel. Be aware that both compiling your own kernel or recompiling an existing distribution usually means that you have to maintain your kernel yourself.

The following figure shows where to find the kernel configuration menu option for the GenWQE device driver:

       GenWQE PCIe Accelerator --->                           (CONFIG_GENWQE)

The CONFIG_GENWQE option is required if you want to use zlib hardware acceleration through GenWQE. The GenWQE device driver can be compiled as a separate module, genwqe_card, or built-in.

You also need the common code option CONFIG_PCI.
