    Actually that's not quite true. ChrisF got the tessellation stuff mostly into shape for core and i965. Marek and I have patches enabling tess on radeonsi and nvc0. Chris has been hitting a lot of...

    The comments made it sound as if nouveau drivers don't work. My point is -- they usually work just fine. You just don't get the full performance of the card. But you do get correct rendering, and the...

    Perhaps you have some feedback on where the nvc0 driver falls short? Note that you don't get to complain about low fps due to low clock speeds -- that's well outside the purvue of the mesa driver and...

    If you don't file bugs, it'll never get fixed. Happy to look at the issue if you file a bug at http://bugs.freedesktop.org/
  5. I don't see why not - it would be difficult to...

    I don't see why not - it would be difficult to change the vbios around, but certainly possible. In fact for a bunch of these cards, you can get them into highest mode by telling nouveau to switch to...

    Of course if you were using a lower-end Kepler card, you'd more likely be able to reclock to the maximum speed (GDDR5 being the main sticking point in reclocking failures... if you have DDR3, success...

    It seems perfectly reasonable to recommend drivers that work better with your software, but the fact that the bugs and performance issues were identified but never reported seems... very odd.

    Actually, not a lot of changes to nouveau of late.

    git log mesa-10.3.. src/gallium/drivers/nouveau/

    shows just a handful of changes that weren't also backported to 10.3 stable --...

    Except... they didn't use a Kepler. They used a Maxwell chip. According to the lspci results, it's 10de:1341, which pci ids lists as a GM108 (http://pci-ids.ucw.cz/read/PC/10de/1341). This is not at...
  10. With Kepler reclocking, available experimentally...

    With Kepler reclocking, available experimentally since 3.16, your own testing showed that nouveau hits about 80% of the blob's performance in TF2 and... whatever other game you tested was. The higher...

    Report bugs that you have via bugs.freedesktop.org ... otherwise they'll never get fixed. IIRC 3.16 got a bit of an upgrade in the types of fans it was able to control. But perhaps the thresholds in...

    Is this a surprise to anyone?

    Is it actually interesting to anyone to see comparisons of nouveau to the blob driver when they're running at vastly different clock speeds? Isn't it kind of a given that way lower clocks -> way...
  13. The 6000 and 7000 series cards should reclock...

    The 6000 and 7000 series cards should reclock just fine today (with a few occasional exceptions). 8000 series and 9000 series cards will take some additional effort (G8x, G9x, G200) -- the model...

    Of course by that logic, no one's making any such CPU's either. (At least not Intel/AMD.) They all require microcode, which is very much closed.



    The full source is included in the kernel (look...

    Might want to check it with a clean mesa build rather than with the gallium-nine patches on top (which also modify drivers). I haven't heard of any such issues until now.
  16. Well, the only place where nvc0 is behind intel...

    Well, the only place where nvc0 is behind intel is its lack of ARB_shader_atomic_counters (which are actually missing in gallium as a whole). This should not be difficult to implement, but is also...
  17. It's blocked and one has to patch. However the...

    It's blocked and one has to patch. However the reason it's disabled is that it's generally not worth trying. The memory reclocking logic that was there for nv50-era cards got essentially dropped in...

    Correction: For nv40 (all nv4x), nvaa (nvaa/nvac), and nve0 (nve0+), it'll actually be enabled by default. Hence the advice to use with caution :)

    For NV40, it should generally work, with rare...

    What instructions? It's just a question of adding the piping between the stages, which will largely mirror what GLSL has. The TGSI modifications shouldn't be too difficult... probably just adding a...

    Actually the nvc0 driver already has a bunch of the necessary support for tessellation (and there's no way it'll happen on nv50 -- while it could be emulated, it would be very slow, thus useless)....
