Re: DRI doesn't work on 2.4.0 but does on prerelease-ac5

Re: DRI doesn't work on 2.4.0 but does on prerelease-ac5

[Michael D. Crawford]

OK, I built XFree86 4.0.2 and DRI seems to be working for me now under
2.4.0-ac4.  (Starting with 2.4.0, it wouldn't, this is with an ATI XPert 2000
AGP).

BUT - although /var/log/XFree86.0.log documents the startup of DRI, DRM and AGP,
and states the info about their initialization and stuff so that it looks like
they're working, I don't notice any performance difference running any of the
Mesa-3.4 demos whether or not I use DRI, and whether I run 4.0.1 or 4.0.2.

This makes me suspect it's not really working, or else my build of the Mesa-3.4
library wasn't configured right - but note that if I disable DRI, one of the
Mesa demos will comment that it's not available.

A specific example is Mesa-3.4/demos/gloss.  It's a rotating textured cylinder
that is partially reflective of what seems to be a landscape that is in front of
the screen being reflecting back to the viewer.  I get a pretty consistent 7.5
frames per second:

- in 4.0.1 with no DRI
- in 4.0.1 with DRI
- in 4.0.2 with no DRI
- in 4.0.2 with DRI

Having agpgart and drm/r128 compiled in or as modules also doesn't appear to
make a difference.

The frame rate for gloss drops to about 3.5 if I run geartrain (another demo)
alongside it.  Geartrain by itself seems to be about the same speed in all
cases, though it doesn't report a number.

There are a couple benchmarking tools in Mesa if someone wanted hard numbers
from me.

Can anyone suggest any 3D code that I can download that does more complex things
than the mesa demos that I can test this with?

Is my DRI really working?  If not, any tips on getting it to do so?

It sounds as if you're using a Mesa lib that doesn't support the
X DRI stuff, just the software renderer.

I have this same problem with a Voodoo 3 2000(tdfx) running 2.4.0 and XFree86 4.0.2.

[OT]: DRI doesn't work on 2.4.0 but does on prerelease-ac5

[J Sloan]

This is a little OT for linux-kernel, but I'll take a swing at it
since I'm running 2.4 and Xfree 4 with a voodoo 3.

After upgrading to Red Hat 7.0, I noticed 3D screensavers
and Quake 3 Arena were dog slow - in the end, I basically
had to make sure the mesa libs didn't get found before the
real opengl libs.

In my case, that meant nuking mesa from my system and
letting Linux use what was left, which got me back the good
accelerated performance - you may choose a less drastic
option. I don't see any breakage from the absence of mesa.

Hope this helps,

jjs

Well, the real problem is that (at least Voodoo3) DRI didn't work _before_
with the "latest" test and pre kernels, and X < 4.0.2 (unless there was some
combination I didn't manage to find) even if it was using the correct
library.

That's odd, perhaps we should compare notes -

I have been getting good accelerated 3D from my voodoo3
since around 2.3.36, except for one brief period around
2.3.99-something where some critical kernel code changed.

I have been using the kernel drm all along.

BTW I am using the X server from 3dfx.com -

Seeing that it _finally_ worked (that qbert spongies xscreensaver thing is
hilarious:) I cleaned up all the logs, along with the mesas and glides
builds .. so right now all I have is a working setup (which I can't complain
about)

IIRC I started trying to make it work around 2.3.99 but wasn't as fortunate
as you since as mentioned it just refused to work.
 
> BTW I am using the X server from 3dfx.com -

Ah, that could have something to do with it, because I always used the
(mirrorerd) xfree86.org binaries.

xircom_tulip + NFS hanging interface

[Pau]

I've been getting problems all along the pre-2.4 series and 2.4 itself
when I use NFS to play mp3 files with xmms.

The message in the logs is:
tulip.c: outl_CSR6 too many attempts,csr5=0x60208100

After a few times the network stops working and it only recovers with the
following sequence of commands:

ifdown eth0 && ifup eth0 && ifconfig eth0 -promisc

Without ifconfig eth0 -promisc it still doesn't get any packet.
I have to stop and start the interface too ad -prmisc doesn't work alone.
So this is the only sequence that works.

The modules loaded are:

Sounds like the version you blew away was not the one built in 4.0.2.
(Mesa is built along with XFree86 now, not as an add-on.)

I will test with my current configuration and see if I can duplicate the
slow down.

I am currently using a Matrox G400 max card with 4.0.2cvs.  I get about
1285 frames per second on the gears demo currently. We will see if that
changes with the 2.4.0 final release version.
