Back in January 2007, Greg Kroah-Hartman, the Linux kernel hacker and Novell/SUSE employee, issued an open offer to device manufacturers.

"The Linux kernel community," he wrote, "is offering all companies free Linux driver development. No longer do you have to suffer through all of the different examples in the Linux Device Driver Kit, or pick through the thousands of example drivers in the Linux kernel source tree trying to determine which one is the closest to what you need to do."

"All that is needed is some kind of specification that describes how your device works, or the email address of an engineer that is willing to answer questions every once in a while. A few sample devices might be good to have so that debugging doesn't have to be done by email, but if necessary, that can be done."

"In return, you will receive a complete and working Linux driver that is added to the main Linux kernel source tree. The driver will be written by some of the members of the Linux kernel developer community (over 1500 strong and growing). This driver will then be automatically included in all Linux distributions, including the "enterprise" ones. It will be automatically kept up to date and working through all Linux kernel API changes. This driver will work with all of the different CPU types supported by Linux, the largest number of CPU types supported by any operating system ever before in the history of computing."
