Pressure stall information (was: Re: linux-signed-amd64_5.0.1+1~exp1_source.changes ACCEPTED into experimental, experimental)

[Harald Weidner <hweidner-lists@gmx.net>]

Hello,

Is there any chance to get pressure stall information (CONFIG_PSI) enabled
on the linux-image 4.20 and 5.x packages?

Pressure stall information are a useful extension to the load average
numbers. They allow a better distinction between cpu, memory and i/o
bound workloads.

See https://lwn.net/Articles/759781/ and https://lwn.net/Articles/759658/
for details.

Best regards,
