PMU/AMU Counters for DGX

[CyrIng]

I’m making a kernel module to read basic cycles but while A725 is capped to 1GHz , the X925 Cores goes up to ~1375MHz.

This is annoying because when scaling the read PMC to the max Core frequency then X925 CPU results in 5 GHz whilst A725 remains at factory 2.8 GHz

Anyone with PMU/AMU experience on Spark ?

Issue is solved.

I found the right PMU event for the Spark which differs from the one for arm v8
