Above is CACHED, not CACHING, so needs to stay to overwrite the
default.
Crap I missed that. Problem is that I wanted to remove the
possibility
to init the system domain with different caching attributes.
I don't see how vmwgfx is every going to use this? Thomas do you
have
any idea what this was good for?
I interpret that like vmwgfx can't handle any other caching attribute
than 'cached'. But I can't see anyone feeding vmwgfx system memory
buffers with other caching attributes. In that case, those would be
ignored.
Yeah, agree. So any objections to change that setting in vmwgfx?
This way we could have the same settings for all drivers in the kernel
and I don't see why any driver should have something special here.
Christian.

Thanks,
Christian.
With that fixed:
