Penny for your thoughts, guys: I am thinking about splitting the |
2 |
video_cards_i965 condition in virtual/opencl so that NEO is pulled in by |
3 |
video_cards_iris instead, and I wonder if there is anything I haven't |
4 |
thought about. |
5 |
|
6 |
The reason why I would like to do this is that there is clear |
7 |
correspondence between compatibility matrices of the Iris OpenGL driver |
8 |
and the NEO OpenCL driver - both only work on Broadwell and newer. There |
9 |
are differences of course, most notably that the old OpenCL driver |
10 |
(Beignet) is already considered deprecated for systems supported by NEO |
11 |
whereas the old OpenGL driver in Mesa (i965) is still the official one |
12 |
even for newer systems. |
13 |
|
14 |
Nb. to the best of my knowledge it is safe to set VIDEO_CARDS=iris even |
15 |
globally because if both i965 and iris are available, Mesa for now still |
16 |
prefers the former unless the environment variable |
17 |
MESA_LOADER_DRIVER_OVERRIDE has been set to 'iris'. |
18 |
|
19 |
There would of course have to be a news item advising the users of |
20 |
virtual/opencl + dev-libs/intel-neo to adjust their USE flags. |

What do you think, guys? |
