guys, can any of you confirm that ?
@Fabio72
empty (non existing) queue/iosched is definitely not good ;)
I saw them sometimes but can't remember when...
10-local-xbian.rules has:
ACTION=="add|change", KERNEL=="mmcblk0", ATTR{queue/iosched/slice_idle}="0"
ACTION=="add|change", KERNEL=="mmcblk0", ATTR{queue/iosched/target_latency}="120"
slice_idle
here is 0 (so these rules are applied), but I don't have a target_latency
:
$ sudo cat /sys/devices/platform/mmc-bcm2835.0/mmc_host/mmc0/mmc0\:0007/block/mmcblk0/queue/iosched/target_latency
cat: /sys/devices/platform/mmc-bcm2835.0/mmc_host/mmc0/mmc0:0007/block/mmcblk0/queue/iosched/target_latency: No such file or directory
iosched
is not empty here, but this a Pi 2 (3.18.8+).

I have too ACTION=="add|change", KERNEL=="mmcblk0", ATTR{queue/iosched/slice_idle}="0" ACTION=="add|change", KERNEL=="mmcblk0", ATTR{queue/iosched/target_latency}="120" but root@xbian ~ # ls -l /sys/devices/platform/mmc-bcm2835.0/mmc_host/mmc0/mmc0:59b4/block/mmcblk0/queue/iosched totale 0
Maybe I solved! I found scheduler=noop on my cmdline.txt. I don't kown why, maybe it comes from where I copied the configuration for nfs root. I must wait to go home to double check but after changing scheduler on the fly queue/iosched is not empty any more

I'm getting two error messages at boot. They are very quick so I had to make a video to see something udev error opening /sys/devices/platform/mmc-bcm2835.0/mmc_host/mmc0/mmc0:59b4/block/mmcblk0/queue/iosched/slice_idle and udev error opening /sys/devices/platform/mmc-bcm2835.0/mmc_host/mmc0/mmc0:59b4/block/mmcblk0/queue/iosched/target_latency both for permission denied.
/sys/devices/platform/mmc-bcm2835.0/mmc_host/mmc0/mmc0:59b4/block/mmcblk0/queue/iosched is empty after boot Everything else is working fine, so maybe is only a cosmetic problem.
