Where can I find the PPR for the Ryzen 7 7840HS?

I've had no luck on developer.amd.com finding a PPR that lists the performance events for this processor, which is in my laptop. I'd like to do some performance analysis... I searched by family (25 and thus 19h) and model (116, which I believe is 74h); the closest match was model 70h. Is there a specific PPR for my processor? I want to track L3 misses and otherwise make the Linux "perf" tool more useful.

Update: AMD Support says the PPR for 74h is still under NDA and will be published later.

Yep, that's where I found the model 70h (not 74h) documentation.

jaafar, sorry I have struck out. Please contact AMD support. AMD seems to forget the Pro processors when it comes to details. John.

I have filed a support ticket and will post here if/when they respond. Thanks for the suggestion.

jaafar, thanks. Best of luck, John.

Update: AMD Support says the PPR for 74h is still under NDA and will be published later.

So you were correct about the Family and Model of the mobile laptop processor.

 

According to CPU World the Ryzen 7 7840HS:

1- ZEN 4 processor

2- Phoenix Processor core

3- Socket BGA (FP7r2)

 
With this information at CPUID - WikiChip Processor website it shows:

At Wikipedea verifies the same info as above: https://en.wikipedia.org/wiki/List_of_AMD_CPU_microarchitectures

Otherwise open a AMD SUPPORT Ticket and see if AMD has updated its Documentation to include the Zen 4 processors.

I do not trust third parties. Where is AMD data?! John.
