Context-switch swaps kernel context including. . .

kernel does stuff (initially depending on what caused.

user-ret(urn) latency, which is an additional metric. . user threads - application threads that are managed by the kernel and are running in user space; i.

This additional metric is also traced by the tracer and can be used, for example of measuring the context switch overhead from kernel-to-user and user-to-kernel, or the response time for an arbitrary execution in user-space. This would be extremely slow as a process context switch would be required to make a kernel call and another one when the kernel call returns.

Process Control block (PCB) is a data structure that stores information of a process.

The tracer supports one thread per CPU, the thread must be.

This additional metric is also traced by the tracer and can be used, for example of measuring the context switch overhead from kernel-to-user and user-to-kernel, or the response time for an arbitrary execution in user-space.
