dmesg 3.10.7

When attaching a monitor to the VGA port of my Thinkpad X220i and playing a fullscreen video with VLC (with hardware accel turned on) the GPU hangs and vlc either freezes or simply shows a black video. This used to work with 3.7, but starting with commit 7739c33ba48174204b24c1b867b455318e752787 ("drm/i915: add DP support to intel_ddi_enable_pipe_func") fullscreen video on VGA is broken for me.

System environment:

distribution: Gentoo Linux
chipset: Sandy Bridge
architecture: 64bit
xf86-video-intel: 2.20.13
xserver: 1.13.4
mesa: 9.1.2
libdrm: 2.4.45
kernel: 3.10.7
machine: Thinkpad X220i 4290-W1A

Absolutely sure about that bisect? Does reverting that commit fix your current kernel?

Comment 3 Jens Pranaitis 2013-09-08 18:56:36 UTC

I'm really sorry, I thought the bisect was already finished. The bad commit is d7d4eeddb8f72342f70621c4b3cb718af9361712. I couldn't revert the commit, as it requires manually solving some conflicts and I lack the necessary coding skills.
