Hi, I want to create sysfs entries for my character device in order to manipulate (show, store) the device parameters.
I am registering the character driver by alloc_chrdev_region + cdev_init + cdev_add. what is the preferred method to create sysfs entries for the new character device? The hardware for which I am writing driver is like this Its is a PCI card with 4 or 2 CAN devices(depending on the board varient) on it. /dev/canN will be the dev node for the devices My doubt is whether I have to create sysfs entries in the folder /sys/bus/pci/devices/XXXX or use class_create() + device_create() and then create the entries in the folder /sys/class/my_new_class/? Regards, Arun C
