[Solved] Poor quality dvd play back - intel GM45 Express Chipset

Hi there,

I'm having some trouble playing dvds with any media player, vlc, mplayer, xine.
I get lots of tearing and very jerky playback.  Also quality is quite poor compared to when I use Windows on the same machine.

Its a dell inspirion 1440 with an intel GM45 card.
glxgears reports direct rendering: yes
I'm using no Xorg but the logs seem to indicate that the intel driver is working a-okay.


xf86-video-intel 2.9.1-1
xorg-server 1.7.3.902-1

there is this line in dmesg:

i915 0000:00:02.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
i915 0000:00:02.0: setting latency timer to 64
mtrr: type mismatch for e0000000,10000000 old: write-back new: write-combining
[drm] MTRR allocation failed.  Graphics performance may suffer.
i915 0000:00:02.0: irq 30 for MSI/MSI-X
[drm] set up 31M of stolen space
[drm] LVDS-8: set mode 1600x900 c


Thanks

Did you read the wiki entry re Intel Graphics?: http://wiki.archlinux.org/index.php/Intel


Philosophy is looking for a black cat in a dark room. Metaphysics is looking for a black cat in a dark room that isn't there. Religion is looking for a black cat in a dark room that isn't there and shouting "I found it!". Science is looking for a black cat in a dark room with a flashlight.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

I did try that - I don't have a DVD to play right now.
dmesg however still gives the same messages regarding mtrr:

mtrr: type mismatch for e0000000,10000000 old: write-back new: write-combining
[drm] MTRR allocation failed.  Graphics performance may suffer.
i915 0000:00:02.0: irq 29 for MSI/MSI-X

[drm] LVDS-8: set mode 1600x900 c

As far as I can tell KMS is working.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

Okay, I've tried to play a dvd with either KMS options set as per the forum and I am still having very poor dvd playback.

Does this really having anything to do with the mtrrs?

I've also been having some graphics/display problems, but mine are 3D, game related issues. But it seems the issues may be connected, and this has given me a new angle on troubleshooting, so we can go ahead and tag team this one.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

So after reading through a bunch of stuff I haven't really come across anything like a fix. 
Interesting that most of those bug reports are a year old or so.

Have you tried with another distro?

How much ram is in your machine?  Mine is 4g but I tried it with only 2g and the same things are happening.

Try installing xf86-video-intel-git from AUR.

Sorry I haven't posted/helped for a few days, but I have to send a machine back to the manufacturer for support, and had to install Vista before it went out (a painful experinece I don't care to repeat).


I have 2g. I am fairly sure that most of the problems are related to the setup on Arch, because the Intel 'mobile' graphics cards share RAM and processing power for rendering/hi-definition video, things like that, while standard graphics cards have their own on-board processors/memory for such tasks.

I did use Ubuntu on my problematic machine for a short while, and it worked without error (though, admittedly, I'm only speaking from a couple months of experience with playing games/watching videos, and I never really performed any sort of diagnostic tests or anything).

If you have a large enough USB, you could try booting Ubuntu off a LiveUSB, and see how the playback is from there, but I don't think it would be of anymore use than a fun little test, because I'm fairly sure that it will work flawlessly. Most likely we'll have to troubleshoot this the old fashioned-way: step by painful step, though I would recommend that you follow another thread here about Intel with 3D graphics, because the problems are probably related.

I haven't had a chance to read through all the bug reports that I posted, but I'll go ahead and do that soon and see if I come up with another angle on the problem. I might also be able to get some info off the Ubuntu LiveCD, but I've tried this before, and it usually ends up being a dead-end because there never seems to be any decent ******* documentation on ANYTHING Ubuntu-related. Makes me feel like I'm right back in Windows again. big_smile

Oh Well.


I didn't know anything about the intel-git in the AUR. Thanks for the advice. I'll check it out and see if that will help with anything.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

Sounds super fun...

intel-git - X starts and is really, really, unresponsive but seems to improve.  However no DVD improvements.
intel-newest - has a bunch of deps.  With deps X starts and remains unresponsive but doesn't crash.  I got into a bit of trouble returning to the 'normal' intel drive as X won't run with the newer dep files.

I had a hell of a time getting a DVD to play in Kubuntu - I should try another one.  I've been trying to watch Lost and those DVDs seem quite particular.  I managed to save a liveUSB so I'll play around a bit see what happens.

cat /proc/mtrr is the same under kubuntu/arch AND mtrr errors appear in dmesg.

I want to try and boot with 3g ram see what happens.  One of those links mentioned having problems until all slots were filled and no 4g ram.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

So....

After further research, it seems that MTRR problems are the result of:

A) a problem with the Kernel

B) a problem with your Bios

Additional reading here:

http://www.tikirobot.net/wp/2009/03/01/ … -on-linux/
http://tinycorelinux.com/forum/index.php?topic=3625.0
http://blog.nachtarbeiter.net/tag/mtrr/
http://snippets.aktagon.com/snippets/12 … 4Gb-of-RAM

Which means that you either have a buggy kernel or a buggy bios. Most likely a buggy bios, as apparently, they don't make 'em like they used to.

There are some suggestions in the articles that may be relevant/may work, but do you have any idea how old your bios is? If it isn't up to date, go ahead and try updating it. Also, try doing a system update as well to eliminate a problem with the kernel (if it is a kernel problem, and anything more than an update won't fix it, the issue is beyond me, so good luck with that).

Finally, if the bios update doesn't work, and the suggestions in the links don't work, go ahead and post the output of /proc/mtrr, /var/log/Xorg.0.log, dmesg | grep mtrr, and dmesg.

We'll take one last run at this, but if I can't find anything wrong in those outputs your issue is beyond me.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

Alright,
No dice with a shiny new bios.  Everything rests the same.  I did get an ubuntu playing DVDs and the playback is definitly better.  I'm vaguely thinking of installing Debian to see what happens but I really, really don't want to have to do that - I don't have a spare partition and I don't think I can get this one shrunk down.

So, I believe that I will have to try and do some manual MTRR setup as per the links and see what that brings me.  There are some nice handy scripts that are for computers with different mtrr arrangements then mine so I'll have to do some fooling.

For your perusal I will post dmeg and Xorg and anything to see if you have any other suggestions that don't involve 0xe000000 numbers and whether they over lap or not.

cat /proc/mtrr:

[djolk@tunamelt ~]$ cat /proc/mtrr
reg00: base=0x000000000 (    0MB), size=32768MB, count=1: write-back
reg01: base=0x0e0000000 ( 3584MB), size=  512MB, count=1: uncachable
reg02: base=0x0dde00000 ( 3550MB), size=    2MB, count=1: uncachable
reg03: base=0x0de000000 ( 3552MB), size=   32MB, count=1: uncachable

So I believe reg00 is whats causing problems and reg01 is the vid card?  Actually on second glance lspci seems to indicate that 'base' for it should e00000000.

Anyways, I've figured out I can remove reg03, reg02 with no effect.  Then if I remove reg00 I can get away with removing reg01 and I have a system that doesn't crash and is very, very slow.

Now I just have to figure out what my mtrrs should like and maybe things I'll work.
Here's the rest of the stuff for you to look at.  I'll keep you posted on what happens.

Oops, I meant to type "dmesg | grep MTRR". But the lesson we take away from this is that if you don't pay attention to caps, the error comes and smacks you right in the face.

You already figured it out, you'll have to manually configure the mtrr settings. I have to get to sleep for now, but post whether or not you were able to find a fix by whenever you decide to call it quits. I'll help you tomorrow if you still need it.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

Regarding your comments on a buggy BIOS:

Is this really a BIOS problem?  And if it is then why does it only seem to affect Linux?  DVDs playback no problem in Win7.  As well, DVDs seem to play better in Kubuntu - still not as nice as win7 but the tearing and choppiness is much reduced.

Also my from my reading, my understanding is that this problem is related to the way X and the kernel interact.  Though in these times of KMS I wonder if its less to do with X because video modes are set directly in the kernel.  As I type this I wonder what /proc/mtrr would look like without X running and KMS disabled.  I guess I'll try that.

If you have any thoughts on what /proc/mtrr should look like (With KMS and X) I'd love to hear them.

The bios issue I took from this link, which I posted earlier:

http://www.tikirobot.net/wp/2009/03/01/ … -on-linux/

But as I said, it could be the bios or the kernel. But even with the information you provided me, I honestly don't know enough about the internal workings of either to say with any authority which is causing the problem. Whether the issue exists in Windows is irrelevant, as from that link the bios issue seems to be a Linux-only problem.

In either case, the root of the problem is masked by the fact that you said video playback is better than in Arch, but still not what it should be. And the fact that, in general, Intel graphics cards don't seem to play nice with Linux, regardless of the system they are installed on/bios the user is using. This makes me suspicious of both.

However, rather than trying to track down the root of the problem (for now, at least), figuring out how to correctly set your mtrr should be our priority. If we have to go deeper than that, we will.

Do whatever research you can, and I'll see if I can dig up some info.

Edit: Just out of interest, what bios are you using?

Edit 2: Did you manaually enable KMS, or are you allowing it to be set automatically on boot? If you manually enabled it, did you allow it to be set automatically before/do you know if it was being set automatically before (if you didn't give any resolution options to menu.lst, you should have switched to native resolution just after udev did its thing during boot)?

Edit 3: You didn't mention whether you did a system update. Do you know what version kernel you have?

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

I hate to say it but:

If a system/kernel update doesn't solve your problem

or

If you can't find anything by googling mtrr + linux + "whatever bios you are using"

Than this problem is beyond me. There is information out there, mostly old, but relevant, and if you do some research into manually configuring your mtrr settings, you could probably figure it out. But I just don't have the necessary knowledge to comfortably advise you in how to tweak this part of you system. I wouldn't be able to help you if something went wrong.

From here, I would advise filing a bug report if the above suggestions do not work.

Edit: I didn't mention it in my previous post, but if you want to try some tweaking yourself: whether or not you are using KMS shouldn't have any affect on what your mtrr settings should be. The first link I posted should be a good starting point if you choose to go this route.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

Just a quick response as I don't have the comp with me right now.

I will fiddle around with mtrrs to see what I can get going though I am not quite sure where to start.

The bios is Dell Bios A07, the kernel is from the repos and I resynced earlier today.  I believe its 2.6.32.  Same problem with the git kernel which is 2.6.33 something or other.

Initially I was just letting KMS happen as it happened - ie nothing added to menu.lst no change to mkintcpio.conf.  Currently I am running as per the Intel Wiki Early Start section which looks to be the same as default.

Thanks for your input - I'll be working on mtrrs

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

I was hoping to get something more specific by googling your bios+mtrr, but mostly the same stuff. However, this may be of some help in your venture:

https://issues.foresightlinux.org/browse/FL-2144

Good luck with this, and let me know how it works out.

Also, aside from filling a bug report, you may want to check out http://www.linuxquestions.org/questions/ for some additional help. If you do make a post, go ahead and give me the link so I can follow your thread. I might be able to throw in a helpful word or two, but I think that anyone who able to properly troubleshoot your problem would probably be signifigantly more knowledgable than myself.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

That fixmtrr.sh script doesn't work, unfortunatly as the memory range for my vid card is appearing in /proc/mtrr.  It just isn't being setup quite correctly.

Another question I have:

Desktop effects in the live distros I tried seem to work quite smoothly.  I have yet to try a 3d game but I am wondering and you may not have an answer for me is if I find out a proper mtrr configuration will this have any affect on the way DVDs play back or just give me a few more fps in etuxracer?

Realistically there is only one way to find out.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

Refer to my wikipedia link:

When the CPU cache was moved inside the CPU, the CPUs implemented fixed-range MTRRs ranges which cover the first megabyte of memory to be compatible to what PC-BIOSes provided at that time. These are used to control the cache policy needed for VGA accesses and all other memory-accesses done while the system is in real mode. Above the first MiB, CPUs provide a number of variable-range MTRRs, which can be freely placed and even overlap. These variable-range MTRRs can be used to set the caching-policy of graphics memory and other memory ranges used by PCI devices.

Basically, an improper mtrr setup will affect ALL video performance. The 3D desktop effects aren't comparable to video playback.

Also, with that script, it shouldn't matter whether your /proc/mtrr is setup up or not. It is supposed to correct the ranges, but I can't testify as to how well it works, because its execution is beyond my knowledge. However, I am assuming you tried it and it didn't work.

If you are going to proceed with the tweaking, I would suggest you reference the Ubuntu link I posted earlier, there seems to have been some progress made in that area:

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

I'm glad you reposted that link.  It's got a /proc/mtrr that is very close to mine and I wasn't feeling to sure how to get started.  Thanks.

The fixmtrr.sh script won't disable a mtrr range - it just uses lspci to figure out the correct 'write-combining' entry for your vid card and adds to the mtrr file.  For some people that seems to be all you need. 

I've got a bizarre reg00 that needs to be split up.

I'll post my results when I get something working.

Do you think this counts as a bug?  Should I file a report?

Ah, got it. Obviously your lspci wouldn't be helpful in this instance.

Dumb luck on that last point, I was just taking one last look through the links and noticed that a new post had been made (that thread is over four months old).

I would file a bug report, even if you resolve the issue. That is, if you have the time/want to put forth the effort. At the very least, you could post a link to this thread, so developers know there is an issue/troubleshooting we've done. But it seems that this is an ongoing, non-isolated issue that was thought to have been solved in recent kernel releases. Probably it would be best if they knew it hadn't been completely resolved.

Even if they are already aware, the worst that will happen is they'll announce the problem is being worked on, and close your report.

Re: [Solved] Poor quality dvd play back - intel GM45 Express Chipset

Okay so I got the comp back, reinstalled everything and DVD performance is much, much improved. It either happened with the next version of intel driver or the addition of 'nopat' to the grub config line.

cat /proc/mtrr is still goofy and graphics could be improved - though my only benchmark is how slow kde is.
