I really dislike the idea of adding the omap vram allocator back. Then
again, if the CMA doesn't work

Tomi, what do you think about adding module parameters to allow
pre-allocating framebuffer

Hi
ea what to look for if I can't reproduce it. The issue is not about
display, but DMA allocation, of which I know very little.
So yes, I suggest you try to discuss this with CMA/DMA people.

Hi,
I wonder if there is any progress on the issue? Do you need me to send more
data? Or
should I raise the issue with the CMA maintainer?

Hi Tomi,
I think we should somehow find out what the pages are that cannot be
migrated, and where they come from.
So there are quot;anonymous pages without mappingquot; with
page_count(page) !=
1. I have to say I don't know what that means =). I need to find some
time to study the mm.
