mesa and gallium

So I cant enable the gallium use. After that here, I've heard here that I need to eselect mesa to actually use the gallium drivers, but at the current state of time the module 'mesa' is missing.

De_logics as you can se the gallium is (-gallium) .
you need the 9999 via overlay to get it .

[Letharion]

As hedmo pointed out, the gallium use flag is _hard masked_, the reason being that gallium isn't considered very stable.
You can remove the mask like this:

Code: Select all

mkdir -p  /etc/portage/profile
echo "-gallium" >> /etc/portage/profile/use.mask

but remember that it's masked, probably for a good reason.

Edit: Mesa 7.9 is due out this month. I can't say if that's going to affect the masking, but if you're gonna experiment with gallium that might be interesting to you.
Edit 2: A little bit of more info here: http://en.gentoo-wiki.com/wiki/Nouveau

I'm using ATI.

I didn't know they can mask use. Can I get more info on this thing?

[dE_logics]

Lots of activity on the forum relating this... so how do you use this thing?

[DaggyStyle]

using r600g from svn and it it stable from the initial commit.
keep in mind that I don't play and I don't use desktop effect.

Since you use ati, you need to add x11 overlay and use the eselect mesa module. Emerge the live mesa ebuild. Then you can switch between classic and gallium by eselect.
Nvidia cards don't have a choice between classic and gallium. Info taken from here

i am on rv350 and as far as i know (can got it wrong) its almost good. but not for me.the windows,and effects
are really good and smooth bot the texture is to bad. if i use the terminal and type something i can not see
it on till i move it.that and games dont work for me but i think its just me so my advice GO FOR IT



my .unmask

>=media-libs/mesa-9999
>=x11-libs/libdrm-9999
>=x11-drivers/xf86-video-ati-9999

and if you have r600 and up i think you can get

x11-drivers/radeon-ucode

[dE_logics]

Atleast I can select gl in mplayer if it works...

[dE_logics]

Absolutely no difference with kms turned on or off.

Radeon x1270

eselect mesa list
i915 (Intel 915, 945)
i965 (Intel 965, G/Q3x, G/Q4x)
r300 (Radeon R300-R500)
classic *
r600 (Radeon R600-R700)
gallium *
sw (Software renderer)
classic
gallium *

[hedmo]

jepp thats just like iv got but on the old
eselect-mesa i had r300gallium and that one is not in
x11 overlay any more . you need kms in your kernel to get it
to work better. the odd thing for me about gallium
more then text and games is glxgears and glxinfo.
glxgears drops from 1500 to 100 fps but stable
and glxinfo shows none or low on all.gallium is
realy good on the D.E .hd films 3D effects xinerama and stuff like
that works fine

[dE_logics]

You mean support has degraded like it has always been.

What are your CFLAGS? With which USE flags have you compiled mesa?

[hedmo]

CFLAGS="-march=k8 -O2 -pipe -fomit-frame-pointer"

x64?

[hedmo]

yes

[dE_logics]

Can you make a binary package for mesa and eselect-mesa? and then upload?

[dE_logics]

In sabayon however I get 400+ FPS.

It's a kernel issue. Any advices?

[hedmo]

before i switched to kms i used mm-sources
and got 800fps but could not use r300 gallium but sw gallium
and only with xinerama on

[dE_logics]

But I'm using zen...

mm should be a subset of zen.

[hedmo]

dE_logics you have to give me some info about zen .i dont know about it i (just reading the info i can get from
mr google) and if you want to bleed go mm.zen is not in the gentoo kernel docs.mm is a old 2.6.28 kernel
so i like to know about the zen.by the way mm is the only kernel that dont work for fglrx other wice id bin
used it on my game box.for my r300 box i have bin used it from the start in the gentoo jungle .sad its not updating

[pingufunkybeat]

emerge -pv zen-sources

[dE_logics]

It's not about zen... the thing that's missing in the kernel config is also in the standard kernel.

[hedmo]

mm is from andrew morton and zen is from Con Kolivas

as far as i know mm was (is) a kernel that andrew build against the ordenary kernel with some patches
of some kind.it was along time ago i read it.back to gallium and mesa.try an older kernlel like me
and se what you get.i did like gallium more with 2.6.28-mm1-rc2 then 2.6.35-gentoo because of games
compiz and the fps was as it where before.not compiz without gallium i could not start it i had to low fps
for that.

[dE_logics]

But using the Sabayon kernel (2.6.34) I get 400 FPS... so the missing recipe is not deprecated IMO. After I fix this issue, I'll try gallium and other things, since Sabayon also uses the stable mesa.
