Hello guys,

I've prepared a patch based on my findings for the bbswitch module
(https://github.com/Lekensteyn/acpi-stuff/tree/master/bbswitch). This adds
a proper
check whether a _DSM function is supported or not and make OFF / ON for
vga_switcheroo work for nVidia Optimus models. The patch is based against
the
mainline kernel.

It has been tested on my Clevo B7130 laptop running kernel 3.2 which has a
GT425M
dGPU:
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Pwr:0000:01:00.0
# tee /sys/kernel/debug/vgaswitcheroo/switch <<<OFF
OFF
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Off:0000:01:00.0
# tee /sys/kernel/debug/vgaswitcheroo/switch <<<ON
ON
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Pwr:0000:01:00.0

The iGPU/dGPU LEDS on the keyboard also change as a result.

A second patch to make the device stay off after suspend is in progress.

Regards,
Peter

Hello guys,

I've prepared a patch based on my findings for the bbswitch module
(https://github.com/Lekensteyn/acpi-stuff/tree/master/bbswitch). This adds
a proper
check whether a _DSM function is supported or not and make OFF / ON for
vga_switcheroo work for nVidia Optimus models. The patch is based against
the
mainline kernel.

It has been tested on my Clevo B7130 laptop running kernel 3.2 which has a
GT425M
dGPU:
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Pwr:0000:01:00.0
# tee /sys/kernel/debug/vgaswitcheroo/switch <<<OFF
OFF
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Off:0000:01:00.0
# tee /sys/kernel/debug/vgaswitcheroo/switch <<<ON
ON
# cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :Pwr:0000:01:00.0

The iGPU/dGPU LEDS on the keyboard also change as a result.

Regards,
Peter

Hello,
I have an Asus U36SD laptop with Optimus and Fedora 16 with kernel
3.1.5-6.fc16.x86_64
Any way I can test it?
Currently  I'm using acpi_call to switch off nvidia card and gain 4w
for more battery life.

[g.cecchi@ope46 ~]$ lspci -vnnn|grep -i vga
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd
Generation Core Processor Family Integrated Graphics Controller
[8086:0126] (rev 09) (prog-if 00 [VGA controller])
01:00.0 VGA compatible controller [0300]: nVidia Corporation Device
[10de:1050] (rev ff) (prog-if ff)

What benefit would it give me? Chance to use nvidia for graphic
related apps ? With nouveau andor nvidia proprietary driver?
Thanks in advance for any pointer

Gianluca

A quickly written way to test this module is described for Ubuntu at
http://pastebin.com/c5XqKSsW. Basically, you need to apply the patch on
nouveau
and rebuild the nouveau kernel module.

A comparison of different methods that works for toggling the dGPU is
available:

</div>Hello,<br>
I have an Asus U36SD laptop with Optimus and Fedora 16 with kernel<br>
3.1.5-6.fc16.x86_64<br>
Any way I can test it?<br>
Currently =A0I&#39;m using acpi_call to switch off nvidia card and gain 4w<=
br>
for more battery life.<br>
<br>
[g.cecchi@ope46 ~]$ lspci -vnnn|grep -i vga<br>
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd<br>
Generation Core Processor Family Integrated Graphics Controller<br>
[8086:0126] (rev 09) (prog-if 00 [VGA controller])<br>
01:00.0 VGA compatible controller [0300]: nVidia Corporation Device<br>
[10de:1050] (rev ff) (prog-if ff)<br>
<br>
What benefit would it give me? Chance to use nvidia for graphic<br>
related apps ? With nouveau andor nvidia proprietary driver?<br>
Thanks in advance for any pointer<br>

Any activity on this? The newly attached patch contains one difference with
the previous
