Hello Daniel,

I used itop [1] now to get a rough estimate. First with kernel v4.14.29-rt25 (fully preempt RT):
INT NAME RATE MAX 19 [ vel tc_clkevt] 397 Ints/s (max: 432) 26 [ vel eth0] 4 Ints/s (max: 38)
Next test with kernel v4.15.13 gives (slightly slower, but non-RT):
INT NAME RATE MAX 19 [ vel tc_clkevt] 248 Ints/s (max: 273) 26 [ vel eth0] 4 Ints/s (max: 11)
With kernel v4.16-rc7 plus this patch series and tcb as clocksource:
INT NAME RATE MAX 17 [vel timer@fffa] 2164 Ints/s (max: 2183) 26 [ vel eth0] 5 Ints/s (max: 10)
Is this the information you wanted? If not, could you point me on how to get the requested irq rate?
