Porting GCN pre-1.2 parts from radeon to amdgpu kernel driver

[Alexandre Demers]

Hello to both of you,

I've been following the development mostly of the radeon driver for some 
time (with some small commits here and there as you may know). I was 
waiting to hear some news about the coming support of Vulkan API. And I 
have been wondering for sometime now if it would be a good think to have 
all GCN parts moved from the radeon driver to the amdgpu kernel driver 
(I had figured out it would be possible, but would it be of any use was 
still unanswered). I was also curious to know if the new Crimson 
software would support the radeon driver at some point.

Now, I may have had a clear answer: I just read from Phoronix' editor 
Michael Larabel 
(http://www.phoronix.com/scan.php?page=news_item&px=Help-Bring-Older-GCN-To-AMDGPU) 
that Vulkan would come to the amdgpu driver only, that the blob (which 
should eventually be opened) would support all GCN parts and that the 
only missing part to support GCN pre-1.2 parts with both Vulkan and 
Crimson would be to have them ported from the radeon driver to the 
amdgpu driver. Am I understanding correctly?

I'd be interested to know a bit more about the task and I may try to 
start the work or join someone who would already be interested in doing so.

Any comments on the matter? Any missunderstood thing?

Cheers!
