Context Switch Time
metric on the
window shows the amount of time the CPU spent in context switches. Switch to the
window and hover over the timeline to view the reason for the context switch. In some cases, CPU context switches may represent CPU waits for the FPGA. Look at the
line to identify times when the CPU may have been waiting on the FPGA and vice versa. For instance, when there is no FPGA activity, but CPU activity is high, it is likely that the FPGA is waiting for the CPU to complete a preparation step.
