Hi,
I'm going to emerge media-libs/mesa on a 2017 18.3 iMac that I've installed Gentoo on. I'd like to chose the right video card use flag for my video card, but I can't figure out which one to use. Could someone help me chose the right use flag please?

For my AMD64 box with an X570, the values in make.conf are:
| Code: | | VIDEO_CARDS="amdgpu radeonsi" |

Thanks, I did already have "amdgpu" in my make.conf, but I'll add "radeonsi" as well now. Aren't they two different cards though? A world re-build should be in order after adding "radeonsi" to the VIDEO_CARDS line, correct?
Any idea on the Mesa package use flag? I was thinking it should be either video_cards_r300 or video_cards_radeon, but maybe it should be video_cards_radeonsi instead? The card is listed in the link below as part of the "Arctic Islands" family, which I guess could be inferred as part of "Southern Islands" but it's all a bit confusing to me and they've had previous cards with in the 500 series of numbers so I'm just not certain which Mesa use flag should be used for this card.

They're the names of a couple of drivers which incorporate code to make AMD graphics cards work. For the X570, you need both for reasons I can't be bothered to understand

If you meant
no, that's excessive. It is just a change of USE flags, so
| Code: | | emerge --changed-use --deep @world |
should suffice. (The --deep might be meaningless in this case, I don't know portage in that detail.)

The mesa build should pick up the relevant bits from VIDEO_CARDS.
Portage expands VIDEO_CARDS="amdgpu radeonsi" to USE="video_cards_amdgpu video_cards_radeonsi".
IIUC It's therefore unnecessary (and possibly wrong except in special circumstances) to specify both VIDEO_CARDS and "video_cards_foo"

For my X570, it's a POLARIS_10 (which is relevant if you build the kernel's amdgpu driver support inline and not as a module, because then you need to name to necessary firmware to go with it. Don't worry about that unless you already know about building driver components into the kernel.)

Thanks for all the help Goverp. I changed my make.conf to VIDEO_CARDS="amdgpu radeonsi" and then performed a "emerge --changed-use --deep @world" as instructed and it worked great.
I also used "video_cards_radeonsi" for the video card use flag for mesa and it helped resolve some tearing I was noticing when playing video using VLC (or at least I think it did).
Either way, thanks again very much for all the assistance! |
