For now.
But you can't have everything to start, you need to reach a goal, and
those goals have to be small and well defined.
So how much interest is there in my idea of a graphics card
with a framebuffer and a socket to optionally add the future gpu?
Can we build one with existing off the shelf parts (that have datasheets)?
I am interested, but my target is to pack it into a mini-pcie embedded
design, however I can live with the fact that it can be prototyped as a
standard PCIe card.
Currently, you can do about to 4x PCIe cheaply. That's 10-20gbps.
This clearly indicates that the software compositor could be faster
(transferring multiple data to card is slower than summing it up and
transferring just the end result).
The idea is to get a FLOSS-friendly graphics card available
as soon as possible. Many people would find that it is fast enough.
Recent CPUs have a lot of extra "cores" looking for something to do.
Some of us remember when core was memory. :-)
From slashdot:
"The biggest thing E17 brings to the table is universal compositing.
This means you can use a composited desktop without any GPU acceleration
at all, and use it nicely. We don't rely on software fallback
implementations of OpenGL. We literally have a specific software engine
that is so fast that some developers spent weeks using it accidentally,
not realizing they had software compositing on their setup."
Those who want/need the gpu would still have to wait for the chip,
but as soon as the chip is ready the boards for it would already exist,
amd the non-gpu portions of the software would already be written and
debugged. So the gpu users get theirs faster too. win-win!
