Linux on zSeries
This page contains some of my own work with Linux on zSeries. The official IBM web
pages are available for further information.
I co-wrote the redbook "Linux on IBM
eServer zSeries and S/390: Large Scale Linux Deployment"
(SG24-6824) which is available to read
online or download directly in PDF
I also wrote the "unit record" (ur) Linux kernel device driver which
allows you to make use of the virtual card punch, card reader and
printer that are usually configured for each Linux virtual machine
under z/VM. (For those unfamiliar with the concept, this "punch and
reader" interface is a convenient model/metaphor for functionality
corresponding to a mixture of /tmp, email, unsolicited file
transfer/uploads and such like.) The device driver is officially
available for download as part of the "online associated material" with
the above redbook. For convenience, I also make it available for download here too.
There is also an experimental
patch which allows the choice of a non-default CCW when doing I/O
to a given device. If you don't know what this means, the patch would
be of no use to you.
