05:16 millerthegorilla: imirkin, if you need a gm107 then I'm here all day.
10:37 RSpliet: pmoreau: I think I just got myself an NV50 again :p
10:38 RSpliet: this time with a working fan
10:38 RSpliet: let's see if I can make some time this weekend for reclocking
10:40 imirkin_: yay!
10:40 imirkin_: the real question is does 2x nv50 == nva0? :)
10:47 RSpliet: in terms of power consumption?
10:47 imirkin_: heh
10:47 imirkin_: just an observation that 0x50 * 2 == 0xa0
10:48 mlankhorst: yes :p
13:59 pmoreau: RSpliet: Awesome! Which chipset? (Or is it a *real* NV50?)
13:59 imirkin_: i assume he meant G80
13:59 RSpliet: the real deal yes
14:00 RSpliet: no Diet-NV50
14:00 pmoreau: :-)
14:00 RSpliet: not the margarine of NV50
14:00 RSpliet: "just one calory, not quite NV50 enough"
14:00 pmoreau: Eh eh eh!
14:01 RSpliet: I was hoping for it to be one of those NV92s, but highly unlikely
14:02 pmoreau: I'll have some time to get back to debugging this week-end. :)
14:02 imirkin_: RSpliet: the G92's are like GTX 250 or whatever
14:02 pmoreau: I have a G92 with GDDR3, but only one perf level :/
14:02 imirkin_: yeah, most of the desktop ones had a single level
14:03 imirkin_: i have a G98 with 2 levels
14:03 imirkin_: (one of which is *vastly* lower power)
16:20 koz_desktop: Is there a way I can disable vsync?
16:20 imirkin_: for a particular program you can run it with enable_vblank=0 foo
16:21 imirkin_: if you want to do so globally, you can set GLXVblank to 0 in your xorg.conf
16:21 koz_desktop: imirkin_: Thanks.
16:22 imirkin_: erm, that enable_vblank thing may be off
16:22 imirkin_: give me a sec
16:22 koz_desktop: Where can I find xorg.conf?
16:22 koz_desktop: Yeah - I just tried it and it failed.
16:22 imirkin_: right. vblank_mode=0
16:22 imirkin_: this will only affect opengl programs btw
16:24 koz_desktop: Thanks.
16:25 imirkin_: whereas GLXVblank in xorg.conf will (counterintuitively) also affect XVideo output
16:25 koz_desktop: OK, with that, glxgears is outputting nearly 4k fps.
16:25 imirkin_: good thing you can see each frame on your 4khz monitor ;)
16:26 koz_desktop: Lol. I'm not even sure what my monitor's rate even is.
16:26 imirkin_: run it without vblank_mode=0 and see what fps you get. probably 60
16:26 imirkin_: (you can also look in 'xrandr')
16:27 koz_desktop: 60
16:27 koz_desktop: However, my Minetest FPS is still trash even without vsync....
16:27 koz_desktop: I'm at a loss to explain why.
16:28 imirkin_: well, vsync would certainly not "trash" fps..
16:28 koz_desktop: Maybe my settings are just too high... I have max settings and 512 textures.
16:28 imirkin_: presumably minetest does something a bit more complex than glxgears...
16:28 koz_desktop: imirkin_: Probably, lol.
16:28 imirkin_: i think you mentioned you had a kepler, you've clocked it up i presume?
16:29 koz_desktop: Yep - it reclocks correctly now.
16:30 koz_desktop: Thanks to your guys' hard work.
16:30 imirkin_: and i presume the blob driver gets reasonable performance with this application?
16:30 koz_desktop: I haven't tried - should I?
16:30 imirkin_: past tests indicate that nouveau achieves 50-80% of the performance of the blob drivers, clock for clock
16:31 imirkin_: however i'm sure you can find ways to destroy nouveau on something... it's not nearly as tuned to various applications
16:31 koz_desktop: Also, would compiling Minetest from source help its performance any?
16:31 imirkin_: unlikely
16:31 imirkin_: if nothing else, would be interesting how blob drivers fare
16:32 koz_desktop: OK, I'll give it a run. Right now, I'm trying to find 'ideal' settings.
16:32 specing: minetest works great on blob
16:32 koz_desktop: Is there an inherent fps limit on Minetest?
16:32 koz_desktop: Even on minimal settings, I seem to be capped at 30.
16:33 specing: I don't think so
16:33 imirkin_: koz_desktop: are you sure that the reclocking actually worked? can you pastebin your pstate file?
16:33 koz_desktop: imirkin_: Sure.
16:33 specing: iirc I had >100 on NV50 laptop GPU
16:33 imirkin_: (and dmesg too for good measure)
16:34 koz_desktop: imirkin_: http://dpaste.com/2DJ7CGZ
16:34 koz_desktop: imirkin_: dmesg -> http://dpaste.com/05WDHB1
16:34 imirkin_: skeggsb_: --^ is that what you'd expect? memory is reported as clocked up, but core speed is the "low" one
16:35 imirkin_: nouveau E[ CLK][0000:01:00.0] error setting pstate 2: -22
16:35 koz_desktop: Goddamn it...
16:35 imirkin_: nouveau E[ CLK][0000:01:00.0] failed to raise voltage: -22
16:35 koz_desktop: Looks like it hasn't happened. :(
16:35 imirkin_: need more POWER!
16:35 koz_desktop: Never mind, then.
16:35 koz_desktop: Yeah... same issue as before.
16:35 koz_desktop: :(
16:35 imirkin_: but your memory is going really fast now
16:35 imirkin_: should be worth something
16:36 koz_desktop: Well, let me try to at least get a consistent 30fps.
16:36 koz_desktop: That's better than 14-odd...
16:37 imirkin_: koz_desktop: try level 0a
16:37 imirkin_: might work better
16:37 imirkin_: (NvClkMode=10)
16:37 koz_desktop: imirkin_: OK.
16:38 imirkin_: might be able to do it without raising voltage
16:38 koz_desktop: OK, here goes nothing. Be back in a flash.
16:41 koz_desktop: Nope.
16:41 koz_desktop: Same rate.
16:41 imirkin_: same error increasing voltage in dmesg?
16:41 koz_desktop: Yep.
16:42 imirkin_: o wee
16:42 imirkin_: well*
16:42 koz_desktop: I guess I'll just have to find optimal settings to keep my framerate at ~30...
16:43 koz_desktop: It also appears view distance makes absolutely no difference.
16:44 koz_desktop: Oh well. :(
16:45 koz_desktop: Yeah, the reclocking problem continues to be annoying as hell. :s
16:45 koz_desktop: Makes me tempted to buy a reference 760 or something and see if that works any better.
16:47 imirkin_: i'd advise buying an amd card -- those are fully supported on linux
16:47 koz_desktop: imirkin_: Fully-free distro. Thus, no kernel driver until AMD release AMDGPU.
16:48 koz_desktop: I'd have bought one by now otherwise.
16:48 koz_desktop: Oh well, I'll wait and see. You guys are doing amazing work, and I wish I could help.
16:49 glennk: i sort of fail to see what difference amdgpu vs radeon.ko would make
16:49 imirkin_: glennk: best not to worry about it
16:50 koz_desktop: Is there a bleeding-edge version of nouveau I could try?
16:51 imirkin_: i don't think there have been any changes related to this since 3.19
16:51 koz_desktop: So there'd not be any point?
16:51 koz_desktop: Oh well. :(
