Well, usually they are just the recommended settings from the hardware
team which try to fix or improve things by changing the default values
for the registers.
I work for AMD and sometimes it isn't clear to me either what those
changes are good for. E.g. I would need to dig though a whole bunch of
register documentation and hardware specs to figure that out.
Alternatively I can try to steal some free time from the hardware guy
who initiated the change and try to figure out the background.
Both tasks are rather time consuming and most likely not necessary at
all as long as you don't run into a regression.

Christian.

ignore my noise here :p

Hi,
I think it would be helpful for at least one liner explaining actually
what is even getting "fixed" here? Obviously we assume, given that you
work for AMD, these magics are correct however it does help in case of
issue.
Just for a motivating example, suppose a magic is technically correct as
per hw documentation but there is a bug in the ASIC itself that this
changed caused a regression with then we would know where/how it occurs.
Kind Regards,
Edward.
