When rootfs is on mmc
I can see frantic activity of mmcqd kernel deamon (doing writes?) for
couple of minutes when booting or inserting the card (2 GB of mp3 files).
Crawler doesn't write to the MMC, it only reads it (it writes to sqlite
database in /home/user). I think part of the badness is due to libid3.
You can see this with strace.
It does when rootfs is on mmc. Together with scanning same card (but
different partition) it is lot of I/O on same device. Luckily there are
no heads in the card :-) This also means maybe the metalayer-crawler is
not very healhy for internal flash wear too.
Oh, yes we finally have strace for arm in bora 3.1, right? Will try.
Ditto. I personally liked the 770 player more.
Well, perhaps the library idea is a bit flawed for removable devices and
does not scale well with bigger media? Or can it fly in limited device
like this? How does ipod and other players solve this? Perhaps doing it
in desktop software I guess.
As for improvement, maybe you can scan just the filenames and do some
hash (for card or whole directories) and if there is nothing new do not
parse files inside at all? Will try strace before firing random ideas.
