05:16millerthegorilla: imirkin, if you need a gm107 then I'm here all day.
10:37RSpliet: pmoreau: I think I just got myself an NV50 again :p
10:38RSpliet: this time with a working fan
10:38RSpliet: let's see if I can make some time this weekend for reclocking
10:40imirkin_: the real question is does 2x nv50 == nva0? :)
10:47RSpliet: in terms of power consumption?
10:47imirkin_: just an observation that 0x50 * 2 == 0xa0
10:48mlankhorst: yes :p
13:59pmoreau: RSpliet: Awesome! Which chipset? (Or is it a *real* NV50?)
13:59imirkin_: i assume he meant G80
13:59RSpliet: the real deal yes
14:00RSpliet: no Diet-NV50
14:00RSpliet: not the margarine of NV50
14:00RSpliet: "just one calory, not quite NV50 enough"
14:00pmoreau: Eh eh eh!
14:01RSpliet: I was hoping for it to be one of those NV92s, but highly unlikely
14:02pmoreau: I'll have some time to get back to debugging this week-end. :)
14:02imirkin_: RSpliet: the G92's are like GTX 250 or whatever
14:02pmoreau: I have a G92 with GDDR3, but only one perf level :/
14:02imirkin_: yeah, most of the desktop ones had a single level
14:03imirkin_: i have a G98 with 2 levels
14:03imirkin_: (one of which is *vastly* lower power)
16:20koz_desktop: Is there a way I can disable vsync?
16:20imirkin_: for a particular program you can run it with enable_vblank=0 foo
16:21imirkin_: if you want to do so globally, you can set GLXVblank to 0 in your xorg.conf
16:21koz_desktop: imirkin_: Thanks.
16:22imirkin_: erm, that enable_vblank thing may be off
16:22imirkin_: give me a sec
16:22koz_desktop: Where can I find xorg.conf?
16:22koz_desktop: Yeah - I just tried it and it failed.
16:22imirkin_: right. vblank_mode=0
16:22imirkin_: this will only affect opengl programs btw
16:25imirkin_: whereas GLXVblank in xorg.conf will (counterintuitively) also affect XVideo output
16:25koz_desktop: OK, with that, glxgears is outputting nearly 4k fps.
16:25imirkin_: good thing you can see each frame on your 4khz monitor ;)
16:26koz_desktop: Lol. I'm not even sure what my monitor's rate even is.
16:26imirkin_: run it without vblank_mode=0 and see what fps you get. probably 60
16:26imirkin_: (you can also look in 'xrandr')
16:27koz_desktop: However, my Minetest FPS is still trash even without vsync....
16:27koz_desktop: I'm at a loss to explain why.
16:28imirkin_: well, vsync would certainly not "trash" fps..
16:28koz_desktop: Maybe my settings are just too high... I have max settings and 512 textures.
16:28imirkin_: presumably minetest does something a bit more complex than glxgears...
16:28koz_desktop: imirkin_: Probably, lol.
16:28imirkin_: i think you mentioned you had a kepler, you've clocked it up i presume?
16:29koz_desktop: Yep - it reclocks correctly now.
16:30koz_desktop: Thanks to your guys' hard work.
16:30imirkin_: and i presume the blob driver gets reasonable performance with this application?
16:30koz_desktop: I haven't tried - should I?
16:30imirkin_: past tests indicate that nouveau achieves 50-80% of the performance of the blob drivers, clock for clock
16:31imirkin_: however i'm sure you can find ways to destroy nouveau on something... it's not nearly as tuned to various applications
16:31koz_desktop: Also, would compiling Minetest from source help its performance any?
16:31imirkin_: if nothing else, would be interesting how blob drivers fare
16:32koz_desktop: OK, I'll give it a run. Right now, I'm trying to find 'ideal' settings.
16:32specing: minetest works great on blob
16:32koz_desktop: Is there an inherent fps limit on Minetest?
16:32koz_desktop: Even on minimal settings, I seem to be capped at 30.
16:33specing: I don't think so
16:33imirkin_: koz_desktop: are you sure that the reclocking actually worked? can you pastebin your pstate file?
16:33koz_desktop: imirkin_: Sure.
16:33specing: iirc I had >100 on NV50 laptop GPU
16:33imirkin_: (and dmesg too for good measure)
16:34koz_desktop: imirkin_: http://dpaste.com/2DJ7CGZ
16:34koz_desktop: imirkin_: dmesg -> http://dpaste.com/05WDHB1
16:34imirkin_: skeggsb_: --^ is that what you'd expect? memory is reported as clocked up, but core speed is the "low" one
16:35imirkin_: nouveau E[ CLK][0000:01:00.0] error setting pstate 2: -22
16:35koz_desktop: Goddamn it...
16:35imirkin_: nouveau E[ CLK][0000:01:00.0] failed to raise voltage: -22
16:35koz_desktop: Looks like it hasn't happened. :(
16:35imirkin_: need more POWER!
16:35koz_desktop: Never mind, then.
16:35koz_desktop: Yeah... same issue as before.
16:35imirkin_: but your memory is going really fast now
16:35imirkin_: should be worth something
16:36koz_desktop: Well, let me try to at least get a consistent 30fps.
16:36koz_desktop: That's better than 14-odd...
16:37imirkin_: koz_desktop: try level 0a
16:37imirkin_: might work better
16:37koz_desktop: imirkin_: OK.
16:38imirkin_: might be able to do it without raising voltage
16:38koz_desktop: OK, here goes nothing. Be back in a flash.
16:41koz_desktop: Same rate.
16:41imirkin_: same error increasing voltage in dmesg?
16:42imirkin_: o wee
16:42koz_desktop: I guess I'll just have to find optimal settings to keep my framerate at ~30...
16:43koz_desktop: It also appears view distance makes absolutely no difference.
16:44koz_desktop: Oh well. :(
16:45koz_desktop: Yeah, the reclocking problem continues to be annoying as hell. :s
16:45koz_desktop: Makes me tempted to buy a reference 760 or something and see if that works any better.
16:47imirkin_: i'd advise buying an amd card -- those are fully supported on linux
16:47koz_desktop: imirkin_: Fully-free distro. Thus, no kernel driver until AMD release AMDGPU.
16:48koz_desktop: I'd have bought one by now otherwise.
16:48koz_desktop: Oh well, I'll wait and see. You guys are doing amazing work, and I wish I could help.
16:49glennk: i sort of fail to see what difference amdgpu vs radeon.ko would make
16:49imirkin_: glennk: best not to worry about it
16:50koz_desktop: Is there a bleeding-edge version of nouveau I could try?
16:51imirkin_: i don't think there have been any changes related to this since 3.19
16:51koz_desktop: So there'd not be any point?
16:51koz_desktop: Oh well. :(
