Hello I recently switched from Nvidia binary driver to Nouveau. I have encountered a possible bug in the kernel module. Before I file a bug report I would like to know if this is a known issue or not. I believe it is related to sleep state and power management of the driver. The Bug: When the computer is left on it's own to go to a power save mode X takes 100% CPU-time in its thread. A trace to X server shows this is caused by select-systemcall immediately returning when X is polling its FD's. The FD nro 12 is constantly indicating that there is data to read so X will never sleep. The FD 12 is a r/w socket connected via netlink to kernel's UEVENT. Restarting X resets the problem to wait again for the sleep state. A new sleep will make the problem arice again. Hardware: I have Fermi nVidia gpu GF104 NVC4 (GeForce GTX 460) and i5 quad core amd64 processor Software: System is running gentoo with stable 'default/linux/amd64/13.0/desktop/kde'-profile Kernel: sys-kernel/gentoo-sources-3.18.7 Nouveau driver: x11-drivers/xf86-video-nouveau-1.0.11 Xorg-server: x11-base/xorg-server-1.16.4 KMS is used for selecting video modes. ---- dmesg ---- [ 0.623063] [drm] Initialized drm 1.1.0 20060810 [ 0.623272] nouveau [ DEVICE][0000:01:00.0] BOOT0 : 0x0c4100a1 [ 0.623274] nouveau [ DEVICE][0000:01:00.0] Chipset: GF104 (NVC4) [ 0.623275] nouveau [ DEVICE][0000:01:00.0] Family : NVC0 [ 0.623307] nouveau [ VBIOS][0000:01:00.0] checking PRAMIN for image...

I did strace before with similar results. The problem is inside kernel and
probabply in nouveau driver. Should I try to disable all power management? How
should I debug the running nouveau module?

Yes, so this was all due to this bug: https://bugs.freedesktop.org/show_bug.cgi?id=90482 On Sun, Apr 05, 2015 at 01:56:51PM -0400, Ilia Mirkin wrote:> You can use perf to try to see where the cpu time is going. > > On Sun, Apr 5, 2015 at 1:42 PM, Matti Nykyri <Matti.Nykyri at iki.fi> wrote: > > Hello > > > > I recently switched from Nvidia binary driver to Nouveau.

A trace to X server shows this is caused by select-systemcall immediately returning when X is polling its FD's. The FD nro 12 is constantly indicating that there is data to read so X will never sleep. The FD 12 is a r/w socket connected via netlink to kernel's UEVENT. > > > > Restarting X resets the problem to wait again for the sleep state.
