Hi!
It is sometimes useful to know device access time. Things that I have in
mind are the software-based hard disk inactivity spindown (some brain
damaged IDE drives fail to follow "hdparm -S" if the argument is longer
than 1/2 hour) and sound card muting if it is not touched for a while.
Notebook users might want to powerdown their network cards after
inactivity as well.
I wonder if such functionality is already available or is planned to be
available some time soon?
Earlier discussions I found in the list mention also atime of tty, mouse
and other human interface device (but "access" meaning is somewhat
different).
Thanks
-L.
P.S. For my own purposes of the disk spindown I'm using an ad-hoc patch
(which I wrote as a proof of the concept while using late 2.2 kernels, it
is still functional in 2.4.30, never had time to rewrite it properly) to
ide-disk.c, so that it exports the last access time as
/proc/ide/hdX/last_access. Keeping atime attribute along with device files
themselves seems more logical, but might cause side effects...
