Hi, Because I want add support for a new device (NETGEAR Nighthawk RAX200 router) to OpenBSD I need more detailed information about the Kernel API. Must create drivers for the corresponding devices. Want use OpenBSD as secure router operating system for my CAT8 home network. :)
In the past I have created a simple GPIO driver for the I2C I/O expander PCF8574 from NXP for the purpose of education (baby-steps). Is there an overview for Kernel functions, which can be used by a driver (Locking, IOCTL's, Kernel threads, et cetera.)? Greetings, Johannes
