This is based on patches I sent over a year ago, adding device parameters to debugfs. This would be the first step, making the debugfs only an alternative interface to the module parameters. The path forward would be: * Add debugfs interface to parameters (this patch) * Modify IGT to use this debugfs param interface if available, falling back to module param sysfs (for older kernels) * Make module params read-only * Make module params the initial values for really device specific parameters, i.e. duplicate the params struct in dev_priv and have the debugfs interface modify only that * Start axing out unnecessary module parameters that can live in debugfs only I tested this stuff way back when, this is an untested rebase for comments.
