Radeon 7500 & OpenGL


Hi all,

I hope this hasn't been asked before and overlooked by me.
I used to have an ATI Rage128 AGP and no problems using OpenGL. I just changed it for an ATI Radeon 7500 QW and now XFree reverts to software GL (mesa). What could be wrong? I haven't upgraded any software since!

Thanks in advance !

--- My setup:
linux 2.4.20, agpgart and all compiled in as module

OK, I fixed it: Apparently every time I recompile the kernel, make modules_install overwrites the /lib/.../drivers/char/drm/radeon.o with the kernel's (older) version, my XFree86 CVS tree had the newer kernel module sources in it, manual make + copy by hand + insmod did the trick!

See ya all, I'm gonna fire up my Frames per Second

Hi there,

I hope you're still registered on this board, and hope you will respond, because I have almost the exact same setup (Radeon 7200 is only diff, basically same card) on the machine I'm writing from, and getting the same problem, same messages, and have tried everything except for upgrading XFree86 to the latest CVS tree.

I just recently upgraded to Slackware9, a little after it came out, and was able to use (any)GL on Slack8 & 8.1 just fine, but now I'm getting the same thing you had.

So, if I'm reading your post correctly, you're saying to upgrade the driver sources from the CVS tree? Are you referring to the drm driver sources or the card driver sources? or both?

If you can recall what you did, and post it (doesn't have to be exact, but more specific than what you had), I would be very greatful.

Thanks a lot in advance!!

Hi there,

First of all, about the cvs I used: well the reason I used CVS back then was that XFree86 version 4.3.0 was _about_ to be released and I didn't want to wait, so I got a prerelease from cvs.

Now that 4.3.0 is out, it's _alot_ less fuss to just get the binaries from the xfree86.org site.

Note that if you don't care about 3D acceleration or XVideo, you could just as well use the 'ati' driver in your XF86Config, AFAIK. But if you want full support this is how I got it to work:

The linux kernel contains a specific radeon driver; I don't know if in the Slackware kernel it's included by default but it probably will be. In that case you should have /lib/modules/<kernel-version>/kernel/drivers/char/drm/radeon.o
[ If you don't have this file you will need to recompile your kernel so that this module is compiled; post a reply here if you never done that before and I'll guide you through it ]

Now this kernel driver favours stability over features so it doesn't support 3D. But XFree86 supplies its own radeon.o which does support 3D. So basically you need to copy XFree's radeon.o over the existing one (I suggest backup to old one).

So, it's possible that your XFree86 version already contains it and you don't even have to upgrade. In that case the radeon.o file should be somewhere under /usr/X11R6 [ I forgot the exact path and I'm not working on my linux box right now, I can tell you tomorrow ]. If you find it, see if it differs from /lib/modules/<kernel-version>/kernel/drivers/char/drm/radeon.o and if it does, replace the latter (back up the existing one, you never know :-) Then do a "depmod" (you may get some unresolved symbol errors, never mind). Change the driver to 'radeon' in XF86Config, startup X and keep your fingers crossed

A good way to see if OpenGL works is to use /usr/X11R6/bin/gears, it shows 3D rotating gears and a FPS counter which should be at least about 60fps depending on your system [ you still need the openGL libraries but virtually all distros have 'em ].

Let me know if this works for you!

Good luck,
nukkel

Awesome!! I appreciate the help. I also appreciate the fact you read deeper into my post, and replied to me back on my level, instead of treating me like a n00b, like I would have gotten in some other mailing list or board, and since I wasn't more specific (which I just now realized), you did the best you could.

I've actually been using Slack since a little after 7.0 got released (about 3 years ago or so), and playing with Linux long before that. So yeah, I do have quite a bit experience, but every once in a while, I'll over-look something and that's where I like to consult others.

Anywho, getting back to the subject at hand, I have done just about everything you've suggested already, short of copying the driver from XFree to my module path. I wouldn't have normally overlooked this, but that's the thing about XFree86 that I wasn't sure about, where it pulled it's drivers from when it starts up.

So, it's safe for me to assume that XFree86 pulls it's video drivers from /lib/modules/2.4.20/kernel/drivers/char/drm/ then?

And let me get this straight, you're saying copy this one:
Code:
@gamestation:/usr/X11R6/lib/modules/drivers$ ls -al radeon_drv.o
-r--r--r--    1 root     root       134559 Mar  2 02:49 radeon_drv.o
over this one, right?:
Code:
@gamestation:/lib/modules/2.4.20/kernel/drivers/char/drm$ ls -al radeon.o
-rw-r--r--    1 root     root       103999 May 10 03:21 radeon.o
And keep in mind, the latter only has a latter date due to kernel recompile.

I'm going to kick myself for not trying that sooner, lol.

Thanks.

Also, glxgears is the only gears thing I can find, and that always works because the glx extension gets loaded.

I'm running out of ideas.... any other help is greatly appreciate.

Hi The_Dot,

it's always nice to help out folks :-) It's just not always as easy to determine the amount of experience someone has based on his/her postings... Hence people getting frustrated sometimes...

Anyway to get to the point:

I think you copied the wrong file over: see, radeon_drv.o is the XFree86 driver (XFree86 4.x.x is modular, as you'll know, whereas XFree86 3 used different binaries for different video adapters) So /usr/X11R6/lib/modules/drivers/radeon_drv.o is the actual video driver...

The /lib/modules/.../drm/radeon.o on the other hand is actually doing all the AGP related stuff; it's more low-level than the radeon_drv.o; in fact the radeon_drv.o is not a kernel module, radeon.o _is_ (sorry for the confusing filenames ! ;-). [ Just try "insmod /usr/X11R6/lib/modules/drivers/radeon_drv.o" :it'll fail ].
The /lib/modules/.../drm/radeon.o module is usually loaded when some direct rendering is needed (hence the dr in drm). So for OpenGL or XVideo (=video hardware scaling).

Problem is, I can't remember exactly where in the /usr/X11R6 it was located... It was a directory which had "linux" in it since it's a OS-dependent thing of course. Now that I think of it, it was probably somewhere in my source tree after I did "make" on the cvs source, if I remember well. But it was in any case "radeon.o", _not_ radeon_drv.o. The install did not however put this module in /lib/modules automatically, I had to figure that out myself

About glxgears: I meant that, not gears, sorry. I'm at home now with only a Windows XP (yuck) box at my disposal... As I can see from the output, you're stuck on mesasoft software 3Drendering, same problem I had

So I see 3 possible things you could do:

* get new binary packages for XFree86 and see if radeon.o is somewhere in there (they're tar.gz's so you can see manually)

* I can email it to you (i686, linux 2.4.20) but to be honest you should never accept binaries which run as root from strangers

* Best option IMHO: Get the ftp://ftp.xfree86.org/pub/XFree86/4..../X430src-*.tgz files, there's a directory xc/programs/Xserver/hw/xfree86/os-support/shared/drm/kernel/ in it, but to compile it you'll need to unpack the whole source tree to get it to create the Makefiles. You may even need to compile the whole thing, because it's not your everyday configure/make/make install thing - just read the instructions. IMPORTANT: IMHO it's not necessary for you to actually install the new version if you don't want to disturb your system too much, just get it compiled and you should be able to grab the radeon.o file somewhere in the tree! I guess it works fine with earlier X versions like 4.2.0.

Hope you have a fast internet connection and some time to spare: my machine compiles a kernel in 15 min. but took 5 hours (!) to build XFree86 4.3.0

Good luck,
nukkel

P.S. How does one insert those smileys the forums?

That stuff I wrote about radeon_drv.o versus radeon.o is mighty confusing now that I re-read it. Actually it's just this:

radeon_drv.o is the driver for the VGA card chipset which is, say, "common" to all architectures, where radeon.o is specific to the OS to communicate with the card over the bus.

So e.g. a FreeBSD system with X and the same graphics card would also use the exact same radeon_drv.o but not radeon.o which is specific to the linux kernel...

Ahhhhh, the picture becomes clearer, and yes, I did have the module fail upon loading of X after copying radeon_drv.o over to /lib/modules/.../drm/.

The odd part is glxgears ran smoother, even had a higher FPS readout... *raises an eyebrow* even though it completely disabled DRI because of the module failing insertion. But I'm guessing that's because it's still accelerating 3D but without full support for GL.

Well, whenever I upgrade Slack, I download the entire directory tree for the version I'm downloading, so I do have the source for xfree86 on one of the cds I burnt, and I guess I'm going to be going back and compiling it from source. I'm going to see if the source has that driver already built or not first, and if worse comes to worse, well... I probably won't be back on this box until later tonight anyway, lol, since I usually spend Saturday eves with the wife.

It sounds like we have almost the same system as it only takes about 15 - 20 mins to completely recompile a kernel on my system as well (it wouldn't happen to be a Dell you were working on, would it? lol). So I think it's pretty safe to assume that the 5 hours you mentioned is around how long it's going to take to recompile XFree86 on here as well.

And about the smilies, you can either just text them in....
Code:
: )
: jawa : (the hooded one)
: Pengy : for tux
: newbie : for the newbie graphic
: D is the big smile
(just take out the extra spaces in stuff, of course,
and make it like :example: or for the other ones :X )"
or you can hit Post Reply near the end of the bottom of the thread as opposed to just the quick reply button at the very end. Then you have a bunch of nice features open to you.

Anyway, I'm off for now, going to try what you suggested, and I'll post either later tonight or tomorrow to let you know how it went.

Later,
The Dot

P.S. You can always email me that driver so I can try it out. Just gzip it and ship it off via the address in my profile. I'm not too worried about this system. This is sort of my test system anyway, and I have very good security measures in place.

Talking WOOOHOOO!!!

IT'S WORKING!!

Ok, so here's what I did.

I found the cd that had the source for XFree86. The guys over at Slack actually had a build script all ready to go, so that made things easier. As any good compiler knows though, anything you get from anyone else, you always check out, which I did, and everything seemed ok, because it didn't actually install it, it just built it and put the build in /tmp.

Nonetheless, it still took a little over 4 hours to build. Thank goodness I had other stuff to do during that time. Actually, the timing couldn't have been better.

So, when all was done and built, I searched through the build down the path you said /tmp/xc/programs/.../drm/ Low and behold, the header files, and c files are sitting there for the making of the driver you mentioned. So I ran make -f Makefile.linux, and less than 30 seconds later, the driver was built. I then copied that over to my normal module path /lib/modules/.../drm/ (after backing up what was there, of course), ran insmod radeon, and fired up XFree86 w/KDE.

I'm happy to report that glxgears gave me an FPS rating of 800+ FPS over 5 seconds (where it was 130+ before) in the little window, and 140+ in the expanded window (where it was 20-30 before), and glxinfo gave me the line I was happy to see:
Direct Rendering: Yes

Thank you for all the help getting that fixed!!

Now, I just have one last concern.... A lot of my screensavers, GL and non, even though they are moving faster due to the driver working, they are blinking. It's as if I'm able to see each frame being written to the screen. Would that be just a matter of adjusting my XF86Config file for clock speeds for either the card or the monitor, or am I missing something else? What's the best thing to use for making that file? I've already merged 2 together to get the one I have, but I feel I'm missing something... Did you get that too after getting the driver working right?

Thanks again,
The Dot

Hi! I'm glad to hear it worked out. Seems your system beat mine to it (Anyway it's not a Dell )

Weird thig is, I didn't have to compile my radeon.o separately like you did, but that's probably due to the script, I've never used Slack myself to be honest.

It's true, in the little window glxgears can do some awesome fps'ing, so that looks OK.

About the blinking: I get a little blinking around the cursor when in windowed mode when moving the cursor over the window, not in fullscreen. It's because of the "hardware cursor", so maybe try to add the line
Option "SWcursor" "on"
to the "Device" section of your card in XF86Config.
It's strange that also the non-GL ones suffer...
If you use xscreensaver, try to run them separately to see if it's not the xscreensaver daemon's fault (they're in /usr/X11R6/lib/xscreensaver; add -root for fullscreen (=root-window)
If that doesn't help I don't see what could be the cause
Video card timings are a delicate thing so it may well be the cause... Try if the problem persists in an "easier" mode like 800x600 (you can switch in X with CTRL-ALT-KEYPADPLUS and -MINUS)

Hey, you can do some additional tuning, by default the radeon driver runs in AGP x1 mode so if your mitherboard supports it you can boost it up to AGP x2 or x4 by adding
Option "AGPMode" "4"
to the "Device" section of the card, there's other options too, try http://www.xfree86.org/current/radeon.4.html

To make a new XF86Config file: do "X -configure" (not while running X) as root and you'll end up with a /root/XF86Config.new file you can use as a starting point. Note that it will use the 'ati' driver by default, not 'radeon' and only some VESA modes so you may want to do some tuning afterwards. Note that you can impress friends by making your own video modes (1000x750 or so there's a good howto for this (XFree video timings howto)

Have fun,
nukkel

hey nukkel, i searched /usr/X11R6/lib/modules/drivers/linux far amd wide to see that, well, it only has one file, called v4l_drv.o

??? should i still copy it over to /lib/modules/2.4.20-9/kernel/drivers/char/drm ??? and what would i put in my X config anyways?

Well, appears it is only in the source tree of X, after compilation, not in the installed dir. tree /usr/X11R6

Luckily the XFree folks have put it separately in a tarball,
see the link in my previous post in this thread, go there and get linux-drm-4.3.0-kernelsource.tar.gz , extract, cd to it and "make -f Makefile.linux". If all is well you should end up with the radeon.o file which is the one that shoud be put in /lib/modules/.../drm/

All the previous rambling is because I didn't know they had it available separately at www.xfree86.org

In XF86Config you should simply put
Driver "radeon"
in the "Device" section of your video card.
The aforementioned radeon.o kernel module will then automatically be loaded when you start X.

Feel free to ask if this doesn't work for you!
