Of course, we think about writing something generic for the bus and specific independent code for different controllers (ISA, parallel...) If well designed this framework could accept new later developments with I2C support (ex. hardware monitoring and so on). The purpose of this mail is to collect: 1- opinions about the idea 2- suggestions about the architecture 3- pratical examples of using such a system Our plan is to develop a basic I/O driver for an ISA controller with no bus abstraction (almost ok), then write bus abstraction, a parallel controller driver to validate bus abstraction, and finally an IP network driver to validate the system. Thanks for your contribution. nicolas -- Nicolas.Souchu@prism.uvsq.fr FreeBSD - Turning PCs into workstations - http://www.FreeBSD.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
