After migrating to the current 4.4 kernel, I noticed that the internal timer
no longer works correctly.
When the CPU frequency scaling sets the CPU speed to 333MHz, the "wall
clock" time also slows down to half the normal rate (e.g. a "sleep 1" will
actually take 2 seconds).
This wasn't the case on the 4.0 kernels.
Is this only on linux-xlnx kernels? or linux-yocto and or mainline kernels too?
I've only tested the linux-xlnx kernel (basically, current master).
Something similar was the case in the 3.13 kernel, and it was fixed in 3.15.
But apparently it came back?
Kind regards,
