I'll construct an additional patch to document the edid file (this aught to be a standardized thing for all framebuffers, anyway - and others have done similar/same). And I'll do a separate one for the individual metrics if they're kept in sysfs in the future. >> metrics_misc > > This isn't. sysfs files are "one value per file". If you want to do > something else, like this file, I suggest using debugfs instead. The metrics stuff is a good candidate for moving to debugfs, I guess, in a future patch. For now, anything in that set which violates sysfs guidelines (metrics_misc) aught to just be removed, I guess. These metrics have already been very helpful for comparing different rendering algorithms, for debugging, and it's very helpful for gathering info from end-users that may not have anything other than sysfs set up. There are so many different hardware/software scenarios that there's often no way to have any sense of what's happening without more detailed instrumentation like this.
