[Nouveau] [Bug 25966] New: nv25 : rxvt scrolling is very slow
http://bugs.freedesktop.org/show_bug.cgi?id=25966 Summary: nv25 : rxvt scrolling is very slow Product: xorg Version: 7.5 Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/nouveau AssignedTo: nouveau at lists.freedesktop.org ReportedBy: castet.matthieu at free.fr QAContact: xorg-team at lists.x.org Hi, using rxvt 2.7.10 (from debian sid) has some issue with nouveau : - opening a new terminal, - filling it with data (dmesg for example), - and then scrolling with the mouse is : - slow (we can see a latency) - Xorg eat 100% of cpu There no such problem with nvidia blob (and nv driver IRRC). Oprofile give me : 62336 51.8948 libpixman-1.so.0.16.4 22927 19.0867 libfb.so 16548 13.7762 no-vmlinux 6297 5.2423 Xorg unfortunately I don't have debug symbol.

Some rendering is faster (aa, rgb), but other is really slow. In scrolling test, lot's of cpu is used by kernel.

I guess you have too old kernel to have the vesafb hand-over fixes. It was vesafb, that needed fixing. Also, no need to test the non-KMS mode anymore. The only way is KMS now. Furthermore, you seem to have proprietary remnants in the system: (II) Loading /usr/lib/xorg/modules/extensions/libglx.so (II) Module glx: vendor="NVIDIA Corporation" ... (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found) I wonder if that triggers noaccel mode... maybe not. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

Btw. comparisons to the proprietary driver can be inaccurate, since Nouveau does not adjust clocks, so if there is overall slowness, that might be explained. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

I installed rxvt 2.7.10, but there is no rxvt-xpm that appears in your profile, and scrolling it furiously while full of text still leaves me with at least 70% of CPU idle. What else should we try to reproduce this? Is it an rxvt-clone of some sort, or some extra features enabled? Perhaps you have a different font configuration? Did you search the bugzilla? I recall this is not the first report of rxvt slowness, but I cannot remember where I read about it, nor what was the resolution, if any. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

http://bugs.freedesktop.org/show_bug.cgi?id=25966 --- Comment #17 from Francisco Jerez <currojerez at riseup.net> 2010-02-12 05:52:20 PST --- Rxvt draws itself with bitmap fonts which are never accelerated by EXA, so this is more of an EXA limitation (in a sense it's a deliberate feature). -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

But I saw that other stuff is slow. For example tabs switch in firefox is more slower. Doing a profiling show that nouveau_exa_download_from_screen take lot's of cpu (more than 25%), but I believe this is for another bug report ? -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=25966 Ilia Mirkin <imirkin at alum.mit.edu> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|NEW |RESOLVED Resolution|--- |INVALID --- Comment #21 from Ilia Mirkin <imirkin at alum.mit.edu> --- It appears that this bug report has laid dormant for quite a while. Sorry we haven't gotten to it. Since we fix bugs all the time, chances are pretty good that your issue has been fixed with the latest software. Please give it a shot. (Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git versions.) If upgrading to the latest isn't an option for you, your distro's bugzilla is probably the right destination for your bug report. In an effort to clean up our bug list, we're pre-emptively closing all bugs that haven't seen updates since 2011. If the original issue remains, please make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/ for what we need to see, and re-open this one.
