[Bug 314928] Re: [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys
Although I understand this issue is fixed in karmic, I found that if I issue (under karmic) cat /proc/mtrr I see the output shows that mtrr is not set up. I can fix it for my gpu card by issuing a sudo -s echo base=0xe000 size=0x1000 type=write-combining | /proc/mtrr If I put the echo command inside /etc/gdm/PostLogin/Default , it is ignored in karmic (wasn't in jaunty). I can make it stick by putting it in /etc/rc.local (but with the provisos noted by the posts above). With mtrr correctly setup, their is a very slight improvement in flash performance, so it appears to be doing something. I am not using an intel gpu - I have an nVidia one. My /boot/config-2.6.31-15-generic contains CONFIG_MTRR=y CONFIG_MTRR_SANITIZER=y CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=0 CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=1 CONFIG_X86_PAT=y So does this mean I don't need to set up mtrr in karmic?

AFAIK, this issue still occurs with Compiz disabled or not installed at all (at least, it affects my system that way). The temporary fix is to download and run the fixmtrr.sh script [1] as root (with 'sudo') every time you start up your system. So for example, if you saved the script in your home directory you'd need to open a terminal window and run 'sudo ~/fixmtrr.sh' (without the quotes) on each login.

** Description changed: - When comparing /proc/mtrr of intrepid and current jaunty i noticed there - is an entry missing. + [Impact] + This bug is one of a set of fairly serious issues that afflict -intel users on Jaunty. The problem is that X and the kernel are miscommunicating about MTRR's, and X ends up deleting ones it shouldn't. + + The user-visible effect of this is poor performance in video playback, + such as very choppy flash video. + + [Solution] + The solution for this issue is composed by a kernel patch and a xorg patch, both from the -intel upstream developers. Both of these patches are upstream, and currently included as of the 2.6.30 kernel and -intel 2.7.99.x in Karmic, which does not exhibit the bug. For Jaunty both of these need backported. + + Kernel patch: http://people.ubuntu.com/~apw/lp314928-jaunty/0001 + -UBUNTU-SAUCE-drm-i915-Set-up-an-MTRR-covering-the-GT.patch + + -intel patch: + http://launchpadlibrarian.net/28453154/122_dont_fixup_mtrrs_in_gem_config.patch + + The kernel patch sets the MTRR correctly and the Xorg patch assures that + reloading xorg doesn't wipe it. + + It's not necessary to roll out both patches simultaneously, but both + linux and -intel need their patches in order to make the bug be + resolved. + + [Test Case] + 0. Verify flash video playback is relatively okay + 1. Note contents of /proc/mtrr + 2. Restart xorg + 3. Note contents of /proc/mtrr again, and how it has changed since #1 + 4. See that flash video playback is laggy + + [Regression Potential] + Reasonably low. This change has been reviewed and tested upstream and in karmic for quite a while, and the specific patches being proposed in this SRU have been provided for testers via a PPA and verified to solve the bug.

[Bug 314928] Re: [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys
I ran your patched kernel for quite some time and it was perfectly stable. I moved X on to xorg-edgers version because I was curious about a few other bugs... I've just been looking into going back a few versions and doing the testing as you suggest. However my .28 kernel is now linux-image-2.6.28-13-generic 2.6.28-13.44 which has come from -updates, and dpkg is therefore moaning about older versions. So does this already have the patch in, or should I force the downgrade to your kernel for testing, with the hope of turning your patch into the .45 release? -- [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys https://bugs.launchpad.net/bugs/314928 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Reporters, please take into account that the solution for this issue is composed by a kernel patch and a xorg patch.

Though this might be slightly off-topic, it still is a helper: Here gmplayer usually crashes NBR, but mplayer 'worked', by stuttering a whole lot. The first culprit that I found: pulseaudio. As soon as I ordered it to use sdl or OSS, it played much smoother. (mplayer myfile.avi -ao oss) Now I wonder if and how to replace pulseaudio; or is it going to break something?

[Bug 314928] Re: [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys
@bryce -- could you give us some insite into the x-servers interaction with the MTRRs here. It appears from the logs in the previous couple of comments that the x-server is also attempting to instigate and remove an MTRR for the AGP aperture. Yet it seems to be failing to create in in our case, but still managing to remove it on exit. There appear to be two errors in behaviour here from xorg: 1) it is removing the AGP mtrr regarless of whether it was it that installed it 2) when there is no mtrr at start it seems to fail to add one dispite trying Perhaps you can point me to the right place in X or some docs as to the expected behaviour. -- [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys https://bugs.launchpad.net/bugs/314928 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 314928] Re: [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys
It appears that the i915 family driver used to insert the mtrr in older kernels and returns in the latest drivers in the 2.6.30-rc series. It appears that the current driver only inserts the mtrr when GEM is being used. Had a go at backporting the fix for this from upstream. I have built kernels with this patch, and they seem to work on my Intel based laptop: $ cat /proc/mtrr reg00: base=0x0 (0MB), size= 2048MB, count=1: write-back reg01: base=0x08000 ( 2048MB), size= 1024MB, count=1: write-back reg02: base=0x1 ( 4096MB), size= 1024MB, count=1: write-back reg03: base=0x0be00 ( 3040MB), size= 32MB, count=1: uncachable reg04: base=0x0ffe0 ( 4094MB), size=2MB, count=1: write-protect reg05: base=0x0bde0 ( 3038MB), size=2MB, count=1: uncachable reg06: base=0x0d000 ( 3328MB), size= 256MB, count=1: write-combining If those of you who are affected by this could test out the Jaunty kernels below and report back here that would be very helpful.

[Bug 314928] Re: [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys
I think that message no space left on device means your MTRR registers are all used up. (There are only eight of them.) To check whether MTRR cleanup is enabled, you can run dmesg | grep MTRR. The cleanup process produces the lines original variable MTRRs and then New variable MTRRs (as well as a lot of other output). -- [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys https://bugs.launchpad.net/bugs/314928 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 314928] Re: [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys
That error message write error: invalid argument doesn't mean that there was a syntax error. Instead the kernel is rejecting the command. In my case it added a line to dmesg explaining the rejection: mtrr: type mismatch for d000,100 old: write-back new: write- combining That was because there was already an overlapping MTRR entry, covering the first 4GB of address space, describing it as write-back. The kernel rejects the write-combining MTRR since it overlaps that write- back range. (There are already a bunch of MTRR entries listing uncacheable memory ranges in the first 4GB; but that's permissible, whereas overlap of write-combining and write-back isn't permissible.) This is on an AMD64 machine with 4GB of memory. I did manage to add a write-combining MTRR entry, but only by deleting the entry covering the first 4GB, and replacing it with one 2GB entry and one 1GB entry. This wouldn't be possible on all motherboards; it just happens that on this motherboard, there's no usable memory in the fourth GB of address space; it's all mapped either above or below that. -- [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys https://bugs.launchpad.net/bugs/314928 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 314928] Re: [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys
Having looked into this further, I find that adding the kernel boot parameter enable_mtrr_cleanup does exactly what I'd done in replacing the 4GB entry, and for the same purpose (opening up a range where a new write-combining entry can go). Plus, it's a general algorithm, not something specific to this one motherboard. The sanitizer can be selected by default when compiling the kernel (CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1), but Ubuntu doesn't do so. Looking at this thread: http://lkml.org/lkml/2008/4/28/52 it seems that the kernel developers are moving towards using PAT, rather than MTRRs, for the write-combining regions; but the Ubuntu kernel doesn't have PAT enabled. So people who are getting the write error: invalid argument message might try adding that boot parameter. -- [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys https://bugs.launchpad.net/bugs/314928 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 314928] Re: [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys
This seems to be something requiring a kernel-side change, so assigning a task for linux. I'm leaving the -intel task open just to make it easier to find and keep track of on the X side, but there is not actually work on the X side to be done for this. I don't know about the feasibility of a backport to jaunty, however since it would help address some of the performance issues for -intel, it would be nice if the kernel team could look into it. ** Summary changed: - [i915GM] MTRR entry missing since jaunty - is this intentional? + [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Jaunty) Importance: Undecided Status: New ** Also affects: xserver-xorg-video-intel (Ubuntu Jaunty) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Karmic) Importance: Undecided Status: New ** Also affects: xserver-xorg-video-intel (Ubuntu Karmic) Importance: Undecided Status: Confirmed ** Changed in: linux (Ubuntu Jaunty) Importance: Undecided = High ** Changed in: linux (Ubuntu Karmic) Importance: Undecided = High ** Changed in: linux (Ubuntu Karmic) Milestone: None = karmic-alpha-2 ** Changed in: xserver-xorg-video-intel (Ubuntu Jaunty) Status: New = Won't Fix -- [i915GM] MTRR entry gets removed when restarting xorg - causes corruption on ttys https://bugs.launchpad.net/bugs/314928 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
