Hi Tejun,
the following:
$ cd linux/tools/cgroup
$ sudo python3 iocost_monitor.py sda
tells:
The kernel does not have iocost enabled
Yet:
$ cat /sys/fs/cgroup/unified/io.cost.qos
8:0 enable=1 ctrl=user rpct=95.00 rlat=2500 wpct=95.00 wlat=5000 min=1.00 max=10000.00
$ cat /sys/block/sda/dev
8:0
If useful:
$ cat io.cost.model
8:0 ctrl=user model=linear rbps=528156881 rseqiops=73442 rrandiops=72800 wbps=386453414 wseqiops=79718 wrandiops=73186
What am doing wrong?
Thanks,
Paolo

There was a change to drgn which required a minor update to the script
(9ea37e24d4a9). Can you see whether you see the failure w/ the commit
applied?
Thanks.
