Bug ID: 90482
Summary: Xorg take 100% CPU when using multiple independent
screen configuration
Product: xorg
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org

my xorg.conf
My xorg setup is based on two independent screen (see attached xorg.conf). Most
of the time the Xorg process eat 100% of one CPU core.
I will try to explain what I think is the problem and the fix (or workaround) I
made to the nouveau code.
Basically, the problem is that nouveau add a socket to the xorg socket list but
does not register a handler that will be able to deal with it. When data is
received on this socket the Select call in xorg-server/os/WaitFor.c will return
but the data will not be read. When Select is called again it returns
immediately because data was not read, and again, and again, resulting in 100%
CPU core consumption.
Now, some details (based on xf86-video-nouveau-1.0.11 source code)
To add a socket in the xorg server list AddGeneralSocket is used.
In src/drmmode_display.c AddGeneralSocket is called in two places: line 1605
(via drmmode_uevent_init and line 1554) and 1610. If line 1608 condition is not
meet, a socket is added without an handler so drmmode_wakeup_handler will never
be called with correct data.
My solution is to add a new handler that will only handle the udev part when
line 1608 condition is not meet. See attached patch.

I also have two screen setup and am facing the same problem since beginning of
April.
Strace shows the KOBJENT NETLINK socket in Xorg returning immediately from
select. The host gets around 9000 interupts / sec:

@dura
Thank you for your quick and dirty fix!
I am also suffering the same problem (reported here btw:
https://bugs.freedesktop.org/show_bug.cgi?id=98383).
In case when my xinerama is disabled, your patch is working great. No more 100%
cpu usage!
But when it is disabled and I power up my TV, then I have still have server
crash, but that could be another story (maybe related?).
What is the problem to merge this patch upstream?
