Request: add kernel config CONFIG_TASK_XACCT=y
« on: August 23, 2019, 06:40:03 AM »
There's no /proc/<PID>/io, which is required for, e.g., htop to show per-process io stats. Looks like the problem is with the kernel configuration: these are required for /prod/<PID>/io:

(ref: https://stackoverflow.com/a/39490917/1563960)

but this is the TC 10.1 x86_64 kernel config:

# CONFIG_TASK_XACCT is not set

I'd like to request adding kernel config CONFIG_TASK_XACCT=y to TC x86_64 kernel config.

Many thanks,

Per the description, collecting those extra stats has some overhead. Should be fine for x64 though.
The only barriers that can stop you are the ones you create yourself.
