hi sorry for spam if this is actually just naive. i'm new to linux kernel driver module and planning to write a small driver module for gpio test, here is what confuses me: 1. in the kernel module programming guide from tldp.org, a device is registered with system by major and minor numbers but in recent kernel source( i'm working with 2.6.28.10 ), the files under Documentation/driver-model/ seem to introduce a whole new set of models, also in kernel source, gpiolib and plat-omap/gpio.c seem to follow the new models. i'm not sure if the way described in kernel module programming guide is still valid for recent kernels. 2. for your information, i want to write a simple driver based on gpio interface described in Documentation/gpio.txt and implement a 8-bit read function as well as an interrupt handler, sort of using gpios to emulate a parallel port. this is just a workaround for lacking access to camera interface on IGEPv2 board, so no need to consider portability or whatsoever, is there any problem for me to just use module_init() and module_exit(), as is shown in the kernel module programming guide, instead of going into all those add/remove classes, buses, interfaces? thanks in advance! -- Huayu Yang -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
