Sadly it's no where near as good as it sounds and won't get merged into the mainline kernel, the kernel graphics maintainer Dave Airlie put's it like this.. http://airlied.livejournal.com/76383.html # So to start the GLES implementation is on the GPU via a firmware. # It provides a high level GLES RPC interface. The newly opened # source code just does some marshalling and shoves it over the RPC. # # Why is this bad? # You cannot make any improvements to their GLES implementation, you # cannot add any new extensions, you can't fix any bugs, you can't do # anything with it. You can't write a Mesa/Gallium driver for it. In # other words you just can't. [...] # # Will this mean the broadcom kernel driver will get merged? # No. # # This is like Ethernet cards with TCP offload, where the full TCP/IP # stack is run on the Ethernet card firmware. These cards seem like a # good plan until you find bugs in their firmware stack or find out # their TCP/IP implementation isn't actually any good. The same # problem will occur with this. I would take bets the GLES # implementation sucks, because they all do, but the whole point of # open sourcing something is to allow other to improve it something # that can't be done in this case. -- Chris Samuel : http://www.csamuel.org/ : Melbourne, VIC
