Porting drivers to the 2.5 kernel
The 2.5 development series has brought with it the usual large set of changes to the internal driver API. The end result is a kernel that is far more pleasant to program for, and a more robust and reliable system. The cost of all these changes, of course, is that kernel code - including device drivers - must be updated to work under the new regime. This paper will give an overview of what has changed in the internal kernel API, why the changes were made, and what must be done to make drivers work again. Some familiarity with kernel programming is assumed.
