 Posted: Sun Nov 14, 2010 5:38 am Post subject: Current Status of Gallium on Intel? |
 |
|
| Anyone using Gallium3D with an Intel card? I see the "gallium" use flag is currently masked, so I assume stability is a bit questionable. I believe my laptop (Lenovo T400) has an Intel 945GM, so I'm thinking of giving it a go. |

There's an ebuild for the new dev version in x11 overlay. The gallium useflag isn't masked there, at least not on my ~amd64 arch.
The new dev version was released last month, maybe give it a try?
Here are the release notes of it: http://mesa3d.sourceforge.net/relnotes-7.9.html |

Thanks, I'll give that a look I unmasked the gallium use flag and re-emerged both mesa and cairo with it (both in ~amd64), and X didn't function properly (gdm started, but half the screen was black, etc.). I've since reverted back to no gallium, but may try again with the new version later.
I haven't played around much with the X11 overlay; how stable is it? I run ~amd64 with the gnome overlay on this machine so I'm not super concerned about stability, but I remember when xorg in Gentoo unstable went from 6.8 to 6.9/7.0 (and I'd rather avoid getting into a similar situation again). |

Almost all ebuilds in x11 overlay are live ebuilds and hardmasked as 9999 version. You won't have any updates but mesa. Mesa itself is running fine here and I don't have any problems with it.
Edit:
Oh another thing.. you can switch the renderer even with build in Gallium.
Have a look at "eselect mesa list". |

Due to my intel card I am working with the X11 overlay to finally get my desktop effects working - gallium enabled + live-ebuilds.
Must have been my lucky day that the state from the git worked 
But one thing to mention about kernels: 2.6.37-rc1 causes problems. 2.6.36 works.

| The i915g and i965g drivers can hardly do more than draw triangles. |

| Maybe a lot has changed in week, I found this thread googling for how to get my laptop back to opengl, after I changed KDE to use xrender. The gallium i915 driver is working fine so far (5 minutes in, no invisible menus or anything). |

| What's your underlying hardware? Also for the record, I was having issues with GDM/Gnome. |

KInfo says the renderer is "Gallium 0.4 on i915 (chipset: 945GM)." Compositing doesn't work because I can't make KDE switch to OpenGL rendering, but performance is acceptable. Really not much different than before, other than now I don't have the invisible menus problem.
Now that I look at it, I didn't emerge Cairo with USE gallium. Don't know what that'll change when I do.
| Code: | | [ebuild R ] x11-libs/cairo-1.10.0-r3 USE="X opengl svg xcb (-aqua) -debug -directfb -doc (-drm) (-gallium) (-openvg) -qt4 -static-libs" |
Using X11 overlay mesa

Doubt it's relevent, but emerge --info for compiler and such

To change back to use opengl, just edit your ~/.kde4/share/config/kwinrc while KDE is not running: | Code: | [Compositing]
Backend=OpenGL
CheckIsSafe=true
DisableChecks=false
Enabled=false
GLDirect=true
GLMode=TFP
GLTextureFilter=1
GLVSync=false
OpenGLIsUnsafe=false |
The "enabled=false" is in there, because if something goes wrong, you won't fall back to your login manager. KDE is started with desktop-effects disabled with this setting, so you can play around with the system-settings.
If you do use XRender, it doesn't change anything whether mesa uses classic or gallium. However, with the OpenGL backend gallium won't function properly on my laptop with kwin crashing and restarting every few seconds. With "classic" most effects work fine.
@cynapsis: It might be impossible to switch to classic with "gallium" USE-Flag enabled, depending on the chipset: | Code: | # eselect mesa list
i915 (Intel 915, 945)
gallium *
i965 (Intel 965, G/Q3x, G/Q4x)
classic *
gallium
r300 (Radeon R300-R500)
r600 (Radeon R600-R700)
sw (Software renderer)
classic *
gallium |
i915 and i945 have no classic variant.

My output is different.
| Code: | eselect mesa list
i915 (Intel 915, 945)
classic
gallium *
i965 (Intel 965, G/Q3x, G/Q4x)
gallium
r300 (Radeon R300-R500)
r600 (Radeon R600-R700)
sw (Software renderer)
classic
gallium * |

Ah. Okay that means, that mesa does not install classic drivers for i915 because I have set i965 and for you it's the other way round. Quite nifty, eh?

If I've understood the ebuild correctly, this section only builds the Intel driver you specify if you've given it in your VIDEO_CARDS variable, or all of them if you haven't.
| Code: | # Intel code
driver_enable video_cards_i810 i810
driver_enable video_cards_i915 i915
driver_enable video_cards_i965 i965
if ! use video_cards_i810 && \
! use video_cards_i915 && \
! use video_cards_i965; then
driver_enable video_cards_intel i810 i915 i965
fi |
So yeah, pretty neat. |

Any idea whether there's been updates to the i965 driver? I checked the status page, and it's still listed as WIP, but I don't believe that page is being updated. |

The i915g driver has seen a significant amount of work. In current mesa git, it is now comparable to the classic driver.
For the i965g driver, the situation is unchanged. |
