DaveM> Your version is still broken then.
Ah, classic DaveM. You're obviously entitled to your opinion.
Look at all the problems that swiotlb pops up. I'm not talking about
"can we make it work", but "can we make the performance not suck bad
when the thing is actually used".
IMHO highmem is the only clean and good performing solution for
>4GB machines without IOMMU.
You show me how to make swiotlb faster and more pretty, than we
can talk. :-)
So when someone tells me "on ia64, with 8gb ram, my eepro100 card gets
really crap performance under any load" I will explain the above to
them and let them know that the performance sucks because the ia64
folks refuse to integrate this bug fix :-)
