4) SynPS/2 touchpad:
Why does moving the touchpad lead to sooo many IRQs? I can't look as fast
as the mouse pointer seems to get new data:
62,5% (473,1)<interrupt> : PS/2 keyboard/mouse/touchpad
80 pps @ 6 bytes/packet = 480 interrupts/sec.
You can try using psmouse.rate=40 to limit it to 40 pps which should
bring it to the rate of standard PS/2 mouse at the expense of
as a sidenote: if we know -- like here -- that the next IRQ will be issued
soon, in approximately 1.75 ms (well, at least on my system), might it make
sense to make tick_nohz_get_sleep_length() smarter to know about this?
