Is it feasible to send 30 or more ioctls per second for such an direct mode? Or should this spawn a special purpose sysfs file that is kept open by userspace to continuously update the keyboard? ioctls are quite fast and another advantage of ioctls is you open the /dev/rgbledstring# device only once and then re-use the fd for as many ioctls as you want.
