The PMU
This is a discussion of the PMU (Performance Monitoring Unit).
I have used this with great satisfaction on the BBB (ARM Cortex-A8),
but now find that the same code does not work on the OrangePi (ARM Cortex-A7).
My notes suggested there may be differences on other ARM variants.
A logical place to look is the "ARM Cortex-A7 MPCore Technical Reference Manual", as given in the link above.
This is chapter 11 in the Cortex-A7 section.
Have any comments? Questions?
Drop me a line!
