Subject: Kernel 3.19rc6 flooding intel_check_page_flip warnings when using compton
Date: Mon, 02 Feb 2015 01:35:53 +0200	[thread overview]
Message-ID: <54CEB859.7020003@student.jyu.fi> (raw)

Dear maintainers,

On an Asus Zenbook UX32VD laptop with an i5-3317U CPU and Intel HD4000 
graphics, I'm experiencing the following with the latest 3.19rc6 
mainline kernel (built from the Arch Linux AUR package: 
https://aur.archlinux.org/packages/linux-mainline/ ). The problem is 
related to the compton compositor: https://github.com/chjj/compton

Booting to X goes very normally. Then, I start compton with the command 
`compton --backend glx`. As soon as I do that, the dmesg log starts 
getting filled with these warnings. This is a snippet from my journalctl 
log:

I get about 4-5 of them per second as long as compton is running. 
Starting compton with `--backend xrender` doesn't cause any warnings. 
I'm using the SNA AccelMethod (the default), but switching to UXA or 
Glamor didn't seem to have any effect. I haven't set any i915 specific 
kernel flags.

I don't see this on the current stable 3.18.5 kernel. The first time I 
saw this was on 3.19rc3 when I tried it due to another bug in the 3.18 
series. I haven't gone through all the 3.19 release candidates, but the 
behaviour with 3.19rc6 seems identical to what I saw with 3.19rc3.
