> @xiaoxiang781216 without my patch I'm getting 40ms always (not between 30ms-40ms) and with my patch I'm getting 30ms always (not between 20ms-30ms). It's just because you start the POSIX timer at the same time of schedule timer interrupt(10*n in above example). > If you can describe an situation even theoretical when I can have less than 30ms with my patch, then please describe it. You can try to start your POSIX timer in a GPIO interrupt handler, toggle the GPIO by hand, and measure the result. In most case, you will see what I describe, because GPIO can happen randomly in one tick period. -- This is an automated message from the Apache Git Service.
