Netgear R7800 exploration (IPQ8065, QCA9984)

i need one user that needs to do prolonged test.

let me explain my theory...

# CPU1 min frequency also has to be increased because there is a hardware constraint
 # kraits cannot operate at 384MHz when L2 is at 1GHz.

this is from the original netgear fw...
Now i wonder if the problem here is the small time frame where we change cpu freq
Example:

L2 at 1.4 ghz cpu at 1.4ghz
We change cpu to 1.7mhz:

  • cpu is switched to 384 mhz (safe parent)
  • hfpll reprogrammed to 1.7ghz
  • cpu is switched to the hfpll source (mux out of safe parent)

Now i wonder if in this small time frame cache can get corrupted as the cpu is running at 384mhz and L2 is at 1.4ghz
