Bug ID: 77321
Summary: vga_switcheroo breaks between 3.12.0 and 3.13-rc1 on
MacbookPro 6,2 (Core i5 + Nvidia 330M)
Product: Drivers
Version: 2.5
Kernel Version: 3.13-rc1
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: blocking
Priority: P1
Component: Video(DRI - Intel)
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: jmarcet at gmail.com
CC: intel-gfx-bugs at lists.freedesktop.org
Regression: No
I use a MacbookPro 6,2, with dual graphics, intel and nvidia 330m.
Booting in EFI mode make nvidia the default card. In order to switch to intel I
use vga_switchero, with the following before launching Xorg:
if [ -e /sys/module/i915 ] && \
[ -z "$(grep 'IGD:+:' /sys/kernel/debug/vgaswitcheroo/switch)" ]; then
echo IGD > /sys/kernel/debug/vgaswitcheroo/switch
echo 0 > /sys/class/vtconsole/vtcon1/bind
else
return 0
fi
[ -e /sys/module/i915 ] && rmmod i915
[ -e /sys/module/i915 ] || modprobe i915
Both nouveau and i915 are compiled as modules. I got this working without any
issue, including suspend & resume.
Between 3.12.0 and 3.13-rc1 some change break this and i915 cannot be rmmod'ed
anymore, as can be seen below (entire dmesg @ http://bpaste.net/raw/339596/,
3.12.20 dmesg @ http://bpaste.net/raw/340642/). I could not bisect it beyond
that.
It looks quite (if not directly) related to
https://bugzilla.kernel.org/show_bug.cgi?id=65761 and
https://bugzilla.kernel.org/show_bug.cgi?id=73291
If you need any other details from the laptop, please let me know.
