Changes required/recommended in video4linux drivers:
* some usb webcam drivers (usbvideo.ko, stv680.ko, se401.ko
and ov511.ko) use the video_proc_entry() to add additional
procfs files. These drivers must be converted to sysfs too
because video_proc_entry() doesn't exist any more.
I'd be glad to do this work once your change makes it into the core.
I can do the ov511 work if you want. I can have it done in two days (or
less).
Is there any need for these drivers to export anything through sysfs now
instead of /proc?
Yes, at least with ov511. Some of the info that it puts in /proc is no
longer necessary. However, there are various bits of hardware info that
still need to get to userspace, for scripts that need to tell otherwise
identical (same VID/PID/revision) cameras apart when creating /dev nodes.
Is there a convention for naming driver-specific files in /sys? E.g.:
ov511_foo, _foo, etc...? I don't want to pollute the namespace.
From what I remember, it only looked like debugging and other general info stuff.
There *is* some debugging stuff I would like to keep, at least for now.
Approximately half of the bug reports I get are resolved after I see the
user's /proc info. Is it acceptable to put it all in one file, since it
isn't meant to be machine-parseable anyway? Some of the HCI drivers do
that, right?
