08:33 thum: what is considered the "best" graphics card (GPU code name/family name) supported by nouveau in terms of 2D _and_ 3D support at present?
09:05 gnarface: thum: (none of them) https://nouveau.freedesktop.org/wiki/FeatureMatrix/
09:39 thum: gnarface: do you have some hands-on experience with any of those?
09:40 gnarface: thum: nothing current enough to still be sold new. i can confirm the thing about the G92 freezing when you try to feed it h264 though.
09:41 gnarface: thum: and i can also tell you that 2d and 3d support, even when completely lacking, is usually not what is holding these cards back. usually the complete lack of reclocking support means they idle in the low-power mode and there's nothing you can do about it, so performance is miserable across the board for most the cards even when 3d acceleration *does* work
09:42 gnarface: my advice is just don't spend money on it
10:34 thum: thanks gnarface!
10:35 thum:looks at AMD then...
10:40 imirkin: AMD is definitely the way to go if you're looking for open-source drivers
10:40 imirkin: if you're set on using nouveau, the "best" GPU would be a GeForce GTX 780 Ti
10:44 gnarface: imirkin: is that like, the ONE that actually supports reclocking? or just the one that's the most feature-complete across the board?
11:03 imirkin_: gnarface: just the fastest one
11:03 imirkin_: gnarface: most keplers, GM10x, and GT2xx can reclock
11:03 imirkin_: (i think G96+ in the tesla family)
13:41 thum: thanks imirkin_
14:19 RSpliet: I did implement clock changing for G98 and G200 as well, for which I've had several reported successes (including one or two cards in my collection obvs). Not sure how a GTX 285 compares to a mid-range Kepler in benchmarks though, definitely doesn't win the perf/watt competition
14:21 imirkin_: RSpliet: but it more than makes up for it in the watt competition ;)
14:28 bitozoid: does the graphic card set a limit to the opengl version?
14:29 imirkin_: bitozoid: yes
14:29 imirkin_: DX10-targeted GPUs get you GL 3.3, DX11+ get you GL 4.3 (with all the features of GL 4.5, just haven't fixed up some conformance issues)
14:30 imirkin_: bitozoid: you may be interested in https://people.freedesktop.org/~imirkin/glxinfo/#v=Mesa%2017.1.0
14:31 bitozoid: I have a GT218. It seems nouveau sets a harder limit than nvidia proprietary. Is that possible?
14:31 imirkin_: both should get you GL 3.3
14:32 RSpliet: bitozoid: note that glxinfo might report a 3.0 version string because mesa only bothers with a higher "core" profile, not the accompanying compatibility profiles
14:32 RSpliet: (... double-checks, am I saying this right? :') )
14:32 imirkin_: it's a confusing matter. you're not saying it wrong.
14:32 gnarface: bitozoid: your native mesa install (which nvidia propreitary does not rely on) may be the actual limitation
14:33 gnarface: bitozoid: try getting a newer one if you can (if you're using debian, check backports)
14:33 imirkin_: nv50 backend has supported GL 3.3 for *quite* a while
14:33 bitozoid: http://bpaste.net/show/2ae9388f5d23
14:34 imirkin_: bitozoid: looks like you built without --enable-float-texture
14:35 bitozoid: imirkin_: you are right. I will compile it again. Thanks
14:35 imirkin_: (some kind of patent thing, and float texture rendering is required for GL 3.0)
14:36 RSpliet: imirkin_: is that the same thing as the s3tc patent? Thought upstream mesa sorted that out as of yesterday
14:36 imirkin_: same general idea
14:36 imirkin_: different patent number
14:36 imirkin_: the s3tc patent was only about encoding, btw
14:36 imirkin_: (which naturally is required for that ext)
14:37 RSpliet: Oh... when is it set to expire?
14:37 imirkin_: but usually the encoding is done separately
14:37 imirkin_: in a year or two, not sure
14:37 imirkin_: SGI owns US Patent #6,650,327, issued November 18, 2003. SGI
14:37 imirkin_: not sure if it's under 17- or 20-year rules
14:57 bitozoid: It worked! Thanks
14:59 imirkin_: there are a some outstanding issues on nv50 that i've never been able to diagnose
14:59 imirkin_: but hopefully you won't run into them :)
23:15 RSpliet: imirkin_: but apparently it's "20 years from filing" (june 1998) vs "17 years from grant" (november 2003). This patent might just be set to expire next year...
23:16 RSpliet: Oh... but they can apply for an extension
23:17 RSpliet: Meh
23:17 imirkin_:is not a lawyer
23:18 RSpliet: me neither... the rules are apparently convoluted enough that the expiry date is probably somewhere around 1998+(rand() % 25)
