Building a kernel with the CHSC subchannel device driver

6.10 LPAR mode

Use a kernel configuration option to build a kernel with the CHSC subchannel device driver.

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.

Select the CONFIG_CHSC_SCH kernel configuration option to include the CHSC subchannel device driver (see Figure 1).

The CHSC subchannel device driver can be compiled into the kernel or as a separate module, chsc_sch.
