Hi all,
I used the LTTng to trace a touch panel driver on my device. From the
resource viewer of LTTV, I found the IRQ of my touch panel driver is
triggered every 10ms. But from the oscilloscope, the interrupt signal is
triggered every 12ms. How does that happen?  Could anyone give me some
advices? Thanks for your comments.
