4 PSI - Pressure Stall Information
14 either play it safe and under-utilize their hardware resources, or
19 such resource crunches and the time impact it has on complex workloads
22 Having an accurate measure of productivity losses caused by resource
23 scarcity aids users in sizing workloads to hardware--or provisioning
37 Pressure information for each resource is exported through the
38 respective file in /proc/pressure/ -- cpu, memory, and io.
46 tasks are stalled on a given resource.
48 The "full" line indicates the share of time in which all non-idle
49 tasks are stalled on a given resource simultaneously. In this state
70 Users can register triggers and use poll() to be woken up when resource
78 /proc/pressure/ representing the resource to be monitored and write the
109 window size must be a multiple of 2s, in order to prevent excessive resource
116 Notifications to the userspace are rate-limited to one per tracking window.
118 The trigger will de-register when the file descriptor used to define the

184 cpu.pressure, memory.pressure, and io.pressure files; the format is
185 the same as the /proc/pressure/ files.
187 Per-cgroup psi monitors can be specified and used the same way as
188 system-wide ones.
