need help figuring out how to make this happen. If my pci driver is instructed to open a pci device, I want to change the mode of bar0's sysfs node to o+rw so a user app can mmap it. In other words, from the driver, perform this: chmod 766 /sys/bus/pci/[slot path]/resource0 preferably without a lecture on why I shouldn't .. ;-) If I chmod that sysfs node for bar0 as root, i can run a user process (as regular user) that does an mmap of that and can do reads/writes to the bar resource. I would like for my pci driver to do this automatically when it is told to open a device.
