This patch contains all the available events for the HiFive Unmatched performance monitoring unit.

Depends on patch [3], for the base mapfile.csv file.

I don't see such thing in FU740 v1p3 manual - am i missing something ?

You are absolutelly right, there is no reference to the L2 cache
(Unified Cache) TLB misses event in the FU740 v1p3 manual. But
considering that the FU740 is composed of 1 S7 and 4 U74 cores, I used the U74 core complex
manual
[https://www.starfivetech.com/uploads/u74_core_complex_manual_21G1.pdf]
as the source for events. Did you test the utlb_miss event, and does it
work in your board?

Best,
João Mário

Thank you for pointing this out, it works indeed. Unfortunately not the
first inexactness in the FU740 v1p3 manual.
