your thoughts, guys: I am thinking about splitting the video_cards_i965 condition in virtual/opencl so that NEO is pulled in by video_cards_iris instead, and I wonder if there is anything I haven't thought about. The reason why I would like to do this is that there is clear correspondence between compatibility matrices of the Iris OpenGL driver and the NEO OpenCL driver - both only work on Broadwell and newer. There are differences of course, most notably that the old OpenCL driver (Beignet) is already considered deprecated for systems supported by NEO whereas the old OpenGL driver in Mesa (i965) is still the official one even for newer systems. Nb. to the best of my knowledge it is safe to set VIDEO_CARDS=3Diris even= globally because if both i965 and iris are available, Mesa for now still prefers the former unless the environment variable MESA_LOADER_DRIVER_OVERRIDE has been set to 'iris'. There would of course have to be a news item advising the users of virtual/opencl + dev-libs/intel-neo to adjust their USE flags. What do you think, guys? --=20 Marecki --XdkpiRPHFk4iUGVcOHMVQPtDW3Olsb6mI-- --CkNU1CcOpCGK63Esoy9RhYe5cYPxuvBy0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEE6s2tEGJQYt07jf0riNlchvnoG2kFAl33ogMACgkQiNlchvno G2mvsg/9H6ZBlkGvzVt9IKOgiJpNtQnn8BS4ZD507JJxRy6A34Nt1o/dHKaNN58a stCoW2BVxz8yNmxa+FKJ6XtUyspjN7TUeFton0BIOjDTjbys3oEL5pHPIg50UPK2 roqifJWVnc72FKdos3HqrG8Clv9YdSH9Ud4Auh+sdyBwlObgH5w3M5V+ut68gjir S3qZoblsx/VaR/r96oFBai7A1x2+2zs8ERW7XQr7MbJ/Da2Z1cnQ8hjnKpjV+DMV Gx/g3Smg9sE8RxnRGN04POFfroN+2v5ERkk+vhzQrVPrWrJcLQuNVkVQ7rbTmPbd cFnJE0DWtgnCMbhJpdMVo2GJkFMO9SjiGHVQ+/HUuq2eyTgQ/Fjpg4zuRN6AKvAP HI1ypOqktQtWCVItFB12t7yfmcyspTKrsHW7jDl3A+R1RZ4236u6pPHD6MAaKJbq gAEichxnqri/bN/2s13z6g4rCAmO6UPDCvy5hHj3p+rPd/DsmNPM6482mjkmTp79 KotFlpu+n1BikM+Uo6g1jwnjS5F5Is16EwI+70h/48AtKLWmbbZDDy6xMV+KluM0 VQ9a1XmrAqihTDpwO8BE8Q6ATflKBLL76r5ZzDUn4tYyBmm2FG9rg1Yf7jjNc6sb Vzppqr6q+GpPJSq9dI9iZBcLuUnx7DOvDJpAT0STVDVXzEUGvfM= =L1as -----END PGP SIGNATURE----- --CkNU1CcOpCGK63Esoy9RhYe5cYPxuvBy0--
