AFAIK there shouldn't be any for either methods regarding AMD. I made
also a prototype for AMD, but as there are no downsides for current
method and I don't have any hardware to test it, it's being left out.
Hi Tomasz,
I have an AMD system I can test on, so if you can provide a 'generic'
patch, I'd be happy to try it.
Cheers
Stijn
