Could I get the exactly schedule count in DS-5? As I knew DS-5 working use snapshot, but someone inform me that is worked using interrupt. So he told me we can get schedule information.
Is this right information? Then how can I check schedule information ?
What target are you using? Real hardware or a model? The models supplied with DS-5 don't have cycle information. Fancy, complex, expensive, slow RTL simulators can do it if you have them and access to the RTL of the system.
If you're using real hardware you can read the performance counters (PMU) in software. Or, if you have access to trace, you might be able to use cycle accurate trace,
Hello Scott~!
Thank you for your reply.
could you explain
how to logging schedule information in DS-5?
<event counter="Linux_sched_switch" title="Scheduler" name="Switch" per_cpu="yes" description="Context switch events" />
whether is this full logging or sampling?
if this is full logging, i think i can get the schedule counts.
