mouse usage causes Xorg CPU usage to spike, and mouse pointer becomes less responsive

Nouveau works nicely on my laptop, including suspend and resume, until the power source changes (from AC to battery or from battery to AC).

After that event, mouse pointer gets flaky and I see in /var/log/messages lots of lines like:

Nov 12 01:01:12 localhost kernel: [drm] nouveau 0000:01:00.0: no space while unhiding cursor

Is this 100% reproducible on your system, or a random occurance?

100% reproducible. The timing between power source change and the symptoms varies, but always within minutes I get to the issue.

Right now the only way out seems a reboot, suspending or hibernating leads to a black screen on resume.

I have experienced this same problem on my desktop system a few days ago. I have not used suspend/resume.

It's only happened once, but when it happened, my machine got horribly slow. Restarting X "resolved" the issue.

Affects me too. 100% reproducible by doing the following:

1. Set close lid to blank screen
2. Close lid
3. Open lid

It also seems to happen after 30-60 minutes of general usage.

From that point on any cursor change (mouse over anything) creates the following messages and bursts of high CPU usage:

Rebooting clears this, and doesn't happen with proprietary driver.

In my case suspend/resume works to clear it. I get a black screen with cursor on resume (animation at full speed which indicates problem cleared), switching to a console 2 and back to 1 gets the unlock screen. Once unlocked no cursor problems.

So, a sort of workaround for now :)

Also happens switching to battery for me, as the original reporter indicated.

This just happened to me as well - this is a desktop system so no suspend/resume or anything. The machine had been up for about four days (but unused for the last two) and just suddenly started spitting out those messages every time anything tried to change the cursor.

Tom, which graphic card are you running (use "lspci -nn" to find out)?

The card is:

nVidia Corporation GeForce 8600 GT [10de:0402] (rev a1)

I do have a slightly unusual setup in that I have two monitors attached, one of which is rotated. This has led to one other cursor related problem which is reported in bug #538866.

I'm seeing this problem too, on a laptop, takes a while to occur, then my dmesg gets full of those no space while setting/unhiding cursor errors.

lspci output:

kernel-2.6.31.6-166.fc12.x86_64

I have a dual screen setup and I'm seeing lots of the "no space while setting cursor image" notices. When moving the mouse from one monitor to the other, the cursor gets "stuck" on the previous monitor. This primarily happens when the cursor changes, ie, when moused over a border to resize a window. When this happens, the stuck cursor appears several hundred pixels higher on the middle border of the screen (in this example, with the "resize" cursor).

Are you guys able to update to kernel-2.6.31.9-174.fc12 (http://koji.fedoraproject.org/koji/buildinfo?buildID=147895) and report how things are.

I've been running on that kernel since last Wednesday, and no sign of any problems so far. It can sometimes take a week or more before it happens though so it may still appear again.

Hi Ben, I did not realize there were changes related to this in the latest kernel. I just tried unplugging the power cord and my cursor completely disappeared...

However, after a reboot I was not able to reproduce the issue again, so I'm not really sure about the status of this bug. I will test a bit more then let you know how it goes.

Thanks!

Ben, right it seems the original issue is gone for me.

I think there's more to investigate (for instance, I experienced a black screen with only the mouse visible on a resume after suspend) but I guess I'll open other reports if I manage undestard which usage pattern triggers it.

Yup, I've re-tested and this issue seems fixed for me too.

Miroslav: is this an easily reproducible issue for you? I may have added a fix to nouveau upstream, which'll make it into rawhide soon that will hopefully fix this once and for all. I can't say for sure since none of my cards exhibit the problem for some reason.

The current rawhide kernel has code which'll mostly avoid the issue, making it much harder to reproduce (in theory).

Ben, it isn't easily reproducible :/. My system was running for several days with kernel-2.6.31.12-174.2.3.fc12 and the bug appeared "from nowhere" there too. I will try the new rawhide kernel when it's build. When it will appear after that, I will report back. Thanks for the info.

This problem still happens for me, using the latest upstream git of everything (linux, xorg xorg drivers, etc) as of Feb 18 2010, however it has "improved" a little since earlier. My system chip is Quadro NVS 135M (rev a1).

This kludge to the nouveau driver in linux stops the problems happening for me altogether:

------------------------------------------------------------

This raises a lot of issues - what was happening is that READ_GET() in
drivers/gpu/drm/nouveau/nouveau_dma.c returned EBUSY. It looks to me that
the performance problems are because of a spin lock - if I try increasing
the timeout int READ_GET() from 100000 to 1000000, the performance problems
get 10 times worse.

Secondly, why are nv50_cursor_show() & nv50_cursor_hide()
in /drivers/gpu/drm/nouveau/nv50_cursor.c being called so often? _show
only needs to be called once per attached monitor, and then _hide only when
it really does need to be hidden, ie. when playing a movie or switching VT
(ie. with the above kludge the mouse cursor stays visible on the VT's), not
every time the mouse cursor changes. It could be even my WM (IceWM) making all those calls, I haven't looked into this further.

I don't have time to look into this further at all.

Show/Hide will get called every time the cursor image is updated, however, they'll actually do nothing unless it needs to change the state, which isn't very often.

The reason it's returning EBUSY is because the display engine is hanging for some, yet unknown, reason. Unfortunately none of my systems appear to display the behaviour so I've not been able to track down what's going on yet.

The same is also happening for me with Fedora 13 Alpha (fully updated).

Hardware:
01:00.0 VGA compatible controller: nVidia Corporation Quadro NVS 290 (rev a1)
Intel(R) Core(TM)2 Quad CPU Q9400

xorg-x11-drv-nouveau-0.0.16-2.20100218git2964702.fc13.x86_64

I have been running Fedora 13 Alpha since the release day, and the problem only happened today after about 4 hours uptime and 2 hours of active work. Something is different today than the days before: I've mounted the debugfs at /sys/kernel/debug, which I have not done before today. It would be a strange connection if this was the culprit, though.

I'm running a normal GNOME desktop. It happens when I move the cursor from Firefox to Emacs or vice versa. It does not happen when the cursor moves between Firefox/xterm or Emacs/xterm.

Sorry for spamming, but the only messages I get are "no space while hiding cursor", no unhiding or setting cursor image.

One more thing - it doesn't have to do with Firefox/emacs/whatever. It happened when I moved the mouse cursor from the left screen to the right one and vice versa.

I have two 24" displays at 1920x1200 attached via DVI.

I've never had this problem with Fedora 12 which I've been running extensively until a few days ago.

It happened again today with the same kernel and nouveau versions still. And xorg-x11-server-Xorg-1.7.99.901-8.20100223.fc13.x86_64 (forgot to mention this in comment 26).

When it happened, I tried logging out of the GNOME session which caused both monitors to power down until reboot. I'm attaching an excerpt from /var/log/messages at the time it happened and also the Xorg output, while I'm at it.

Ben, I'm sorry to say this issue is showing itself again, I'm now running the latest F12 bits, kernel-2.6.32.10-90.fc12.x86_64, xorg-x11-drv-nouveau-0.0.15-21.20091105gite1c2efd.fc12.x86_64.

I'm probably going to move on F13 soon so I will be able to say if the same happens there.

Albeit, I'm noticing a difference: this time only one kind of messages is appearing in /var/log/messages:

Apr 5 01:29:41 localhost kernel: [drm] nouveau 0000:01:00.0: no space while unhiding cursor

*** Bug 593695 has been marked as a duplicate of this bug. ***

I originally filed 548545, which was marked as a duplicate of this bug. I just had the same symptom happen: the mouse pointer is no longer drawn when on the left monitor. No messages in /var/log/Xorg.0.log, just this one line in /var/log/messages:

May 28 09:49:10 localhost kernel: [drm] nouveau 0000:03:00.0: EvoCh 0 Mthd 0x0000 Data 0x00000400 (0x0002 0x01)

The mouse pointer is still drawn on the right monitor. This machine is now running F-13, updated this morning. Possibly relevant version numbers:

kernel-2.6.33.4-95.fc13.x86_64
mesa-dri-drivers-7.8.1-6.fc13.x86_64

xorg-x11-drv-nouveau-0.0.16-6.20100423git13c1043.fc13.x86_64

Is this really the same bug?

Something similar seems to have recurred in F-13

[drm] nouveau 0000:01:00.0: EvoCh 0 Mthd 0x0000 Data 0x00000400 (0x0002 0x01)

I get the same message as David in comment #36, then the stream of no space messages with jerky window and cursor behaviour.

nVidia Corporation G84M [Quadro NVS 140M] (rev a1)

I started getting these messages yesterday, I suspect it was when I experienced a sudden very high load and non-responsiveness - I was running a windows machine inside virtualbox so that I could run gotomeeting, and I was given control of the meeting. When I would click on something in the vm nothing would happen until I moved the mouse out of the virtualbox.
But I've continued to get the messages at a lower rate even after suspending the windows machine.
kernel= 2.6.32.14-127.fc12.x86_64

I had this problem a while ago and rolled back nouveau and the problem went away (well it didn't happen again - but of course that's no certainty that the bug was not present in the earlier versions)

The old nouveau that appears to be OK is:
xorg-x11-drv-nouveau-0.0.15-17.20091105gite1c2ef
(that's the one I rolled back to when the mouse problem first showed itself)

5 days ago I did a full update that included:
kernel-2.6.32.16-141.fc12.x86_64 and
xorg-x11-drv-nouveau-0.0.15-21.20091105gite1c2efd.fc12.x86_64
and the problem has happened again today (for the first time since the rollback)

Xorg.0.log info:

First nVidia message is:
nVidia Corporation GeForce 8600 GTS rev 161, Mem @ 0xf6000000/16777216, 0xe0000000/268435456, 0xf4000000/33554432, I/O @ 0x0000b000/128, BIOS @ 0x????????/131072

I use a USB mouse, log says:
Microsoft Microsoft 5-Button Mouse with IntelliEye(TM)

I also have a USB Bamboo that the log finds BEFORE the mouse:
Wacom BambooFun 6x8
(I don't use the pen)

The rest of the log looks like status dumps without any error messages.

In my case it's a dual display and acts even stranger when the problem occurs (randomly?):
The left display shows the mouse correctly (but jerky)
In the right display (which has the menu bar) the mouse works but it is invisible
More strange: the mouse image is partially still shown on the edge of the left screen while using the right screen

When the screen saver comes on the mouse is still visible in the left screen
It doesn't fix the problem when the screen comes back
(thought I'd mention that because I've seen it said elsewhere)

It maybe happens when mplayer is playing fullscreen
(so a fullscreen app may be needed to activate the bug)
Of course when the problem wasn't there I was using the current mplayer version constantly also

The first dmesg error was:
[drm] nouveau 0000:01:00.0: EvoCh 0 Mthd 0x0000 Data 0x00000400 (0x0002 0x01)

followed by lots of the cursor messages (both 'hiding' and 'unhiding')

Minor updates on previous post:
I only boot runlevel 3 and thus always use startx
(as user "root")

Once the problem has occurred:
X menu System->"Log Out root..." fails to go back to the console
(the screen clears to just showing the backgrounds and then stops)

OS is of course unaffected by this - ssh login works fine
(I use that to "shutdown -r now")

I've rolled back to xorg-x11-drv-nouveau-0.0.15-17.20091105gite1c2ef
again (nothing else changed) and will report if it happens again with this
version

Also now had the same problem occur with the older RPM:
xorg-x11-drv-nouveau-0.0.15-17.20091105gite1c2ef

Also, the fullscreen app (mplayer) was not running when it occurred.

Had the same messages for dmesg, /var/log/messages, /var/log/Xorg.0.log as before.
(except no cursor hide/unhide messages)

This time I also got the extra shutdown message (after trying to logout)

However, I have found another problem with my system that may have something to do with the nouveau bug presenting itself.
My USB mouse is possibly failing and switches on and off sometimes ... easy for me to see while dragging windows around, because it sometimes lets go of a window but I haven't released the left mouse button
(I only realised what was going on after my previous comments)

Wow, I'm impressed, many thanks for getting that. FWIW I always have at least 10 xterms open and "xlock -mode blank" is my screensaver, so I always saw the issue after a couple of days at most.

I'm adding a 'me too' to this bug under F13.

Dual Screens, when manifested cursor has issues drawing on left hand screen, appears ok on right hand screen.

Happy to work with people on this one, it's making this workstation nearly unusable.

I have not seen the original behaviour I reported since long, but now that I switched to F14 I guess the best course of action is to close this report and let users on a different release (this was for F12, which is EOL in about one month anyway) or different cards from mine open more specific bug reports.

Same for me. Has not happened once in a very long time (more than 6 months).

Still happening every so often on F12

Really is annoying sometimes to have to kill everything and shut down to fix the problem

(I've ALWAYS booted 'init 3' on all Linux servers because I don't think graphics drivers should be needed to boot a server ... the drivers for a while now have been forced upon us even during an 'init 3' boot ... but I've also had 'init 3' on all my desktops too ... pity it doesn't help with this problem.
My other F12 desktop - dual screen LCD + TV connected - uses that 'other' driver - obviously due to TV-Out - and though I don't work on it much - just for playing DVD's or other videos - I've still never had this problem with it)

I still see the behavior I reported (see comment 35) on F-13 once in awhile. Steve Walsh (comment 44) appears to be seeing the same thing. I'll ask again: is this really the same bug? If not, perhaps bug 548545 should be revived.

I use Slackware, this has got nothing to do with Fedora 12, if this bug gets closed I'm giving up on this and switching to the closed nvidia driver.

Please respect the maintainer and dont be rude.

You should be aware of the fact that this bugzilla instance is to be used with RHEL and Fedora only not for everydistro out there so please file your report either to slackware bugzilla instance if they have one or directly upstream with the nouveau maintainers.

However you are welcome to download the latest Fedora release ( 14 ) install it and try to see if you still experience this problem and if so you can make note of that on this bug.

Thank you.

As the original reporter, I need to note this was for a specific version of nuoveau (the one in F12) with my specific card (with ID in the summary) and that I did not experience anymore mouse movement issues (now I'm on F14, no issues there as well)

If you are running any other combo, I advice to open another, separate report

Band-aid patch that solves the problem for me

Continuing the work I started in comment 42, I was also seeing the "EvoCh 0 Mthd
0x0000 Data 0x00000400 (0x0002 0x01)" messages as everyone else. I did more investigation, and found that not using the last 32 bytes of the Evo ring buffer solved the issue for me -- I no longer get the EvoCh messages, which directly lead to the "no space" messages as seen by the original report and the jerky mouse movements reported by others. This bug is current as of F13, and is likely in F14 and rawhide, as the issue is not yet fixed upstream.

Prior to the patch, dma.max was getting the value 1022. &'ing with ~7 was equivalent to subtracting another 6 entries from that value. I also tried ~3, but that did not fix the issue. I was asked on IRC to try subtracting 5, 4 etc to narrow down the minimum value, and my testing confirmed that subtracting 6 (&= ~7) was minimal. I also tried changing some of the register settings above (NV50_PDISPLAY_CHANNEL_UNK2, etc) but was not successful in teasing out meaning or a fix using them. I have not tried playing with the RAMHT for Evo.

I don't like that my patch involves yet more magic numbers without explanation, but it has been stable for me for the past few weeks, and solves my cursor problem.

Created attachment 457773
Test program that provokes the problem

This program hides/unhides the cursor for the number of cycles given on the command line, default 1. I use this to push the Evo channel's index through the rewind and expose the EvoCh messages. It's much easier than moving the cursor from window to window for a while until things wrap. With my patch, this survives thousands of iterations.

Reassigning to 13 as suggested by Ben on IRC; that will avoid the auto-close.

Can you give the list of libs needed to build the program ?

Thanks.

cc -o cycle_cursor -O3 -Wall cycle_cursor.c -lX11

David, I've been using your patch in comment 53 and it's resolved the issue for me too, thank you very much.

I experienced the same problem on Fedora 14: "no space while unhiding cursor".
This issue is very annoying because the system becomes so slow that I need to restart it.

I'd like to test the patch in comment 53, but I cannot find nv50_display.c.
I've installed the kernel sources (yum install kernel-devel) but the folder "/usr/src/kernels/2.6.35.6-48.fc14.x86_64/drivers/gpu/drm/nouveau" is empty.

I think that the Severity and Priority for this bug should be higher, because, when it occurs, the system becomes so slow that is almost unusable and on my laptop occurs every day.

My video card is:
01:00.0 VGA compatible controller: nVidia Corporation GT216 [Quadro FX 880M] (rev a2)

I'm having the invisible cursor issue and the cycle_cursor app doesn't help with that problem.

I'm not seeing ANY errors in either the .xsession_errors file or in /var/log/messages* .

00:05.0 VGA compatible controller: nVidia Corporation C51G [GeForce 6100] (rev a2)

This one is actually a hardware bug, and not related in any way.

I don't know if my issue is related to this bug, but on my laptop (Compal JFL92) with a 8600M GT card, kernel 2.6.35.8-60 killed my sound. Pulseaudio no more sees the sound card (HDA Intel) and falls back to dummy audio output. No problem at all with 2.6.35.8-59. I'm not sure if this is the right bug to report it, as the kernel changelog reads:

* Fri Nov 19 2010 Ben Skeggs <email address hidden> 2.6.35.8-60
- nouveau: add quirk for iMac G4 (rhbz#505161)
- nouveau: add workaround for display hang on GF8+ (rhbz#537065)
- nouveau: don't reject 3D object creation on NVAF (MBA3)

but this seems the only one related to my hardware.
dmesg doesn't report anything suspicious, but I'm available for any further testing on this issue.

This on F14 x86_64.

Odd, Since in Fedora 12 it worked fine (cursor showed up without any issues). It only seemed to happen after a certain point. Next time I have to reboot, I'll swap to an external card vs. the built in video).

What was your previous kernel? I don't see how these changes could possibly cause what you see.

I guess it's possible something in nouveau now triggers the hw bug more reliably. All previous reports indicate that it would usually come up find, and disappear randomly at some point until a reboot. I used to have the effected hardware (the machine has since died), and even the NVIDIA binary driver could not bring it back once it went.

Previous kernel was 2.6.35-59, and audio still works if I boot it. Yeah I know, it's weird. I'm looking after getting some more info about it, but I doubt I'll have time today...

Sorry disregard my bug report, I verified it's a problem with the new dracut update that triggers when a new initramfs is built, not a kernel problem. Coincidentally the two things overlapped on my system. Sorry for wasting your time.

As I already asked, how may I find nv50_display.c to try the patch in comment 53?

You don't need to, it's in kernel-2.6.35.8-60.fc14 (http://koji.fedoraproject.org/koji/buildinfo?buildID=205566)

Okay, thanks a lot!
I still have the kernel 2.6.35.6-48.fc14.x86_64.

The kernel-2.6.35.8-60 is still a release candidate. May I install it simple by downloading the rpm or it's better that I wait for the official release (is there already a date?) and then updating with yum?

I've now installed the newer kernel (2.6.35.8-60). I let you known, if the problem ("no space while unhiding cursor") occurs again.

I'm using the newer kernel (2.6.35.8-60) for about one month and I haven't experienced the problem above ("no space while unhiding cursor") any more.

In my opinion this problem is fixed. Thanks a lot!
