svm.c patch
Ha! Of course I forgot to add the actual patch I ended up using, so here it is.
But hey, I told you I'm old :)
However I'm still assuming what I did was wrong. Though my VM is working fine,
the CPU-Z benchmark is significantly lower. For example the single threaded
performance is now around 480, and with kernel 5.5.5 it's a little over 500,
around 503 to 507.
Of course this is all anecdotal, and I haven't had time to do any real testing.
But I'm going to wait to hear from you gentlemen before I proceed any further.
I'd especially like to know how to tell if avic is even actually working.
