Hm.. according to the original commit description ON / OFF is used to turn
the not-in-use-card on/off...
What was the behavior before v2.6.38-rc4? I don't know if this was an intended
change in behavior or an unintended side effect of some other change. Dave
Airlie can probably tell though...
p.s.:
Anyway, I presume working around that in userspace is not the issue? (i.e.
maybe doing something like this:
IGDINUSE=`grep IGD /sys/kernel/debug/vgaswitcheroo/switch | awk -F: '{ $3 }'`
if [ x$IGDINUSE != x+ ]; then
echo IGD /sys/kernel/debug/vgaswitcheroo/switch
fi
)

On 2.6.37.6 nothing happens if card is already active: # cat /sys/kernel/debug/vgaswitcheroo/switch 0:+:Pwr::01:05.0 1: :Pwr::02:00.0 # echo IGD /sys/kernel/debug/vgaswitcheroo/switch # cat /sys/kernel/debug/vgaswitcheroo/switch 0:+:Pwr::01:05.0 1: :Pwr::02:00.0 Anyway, I presume working around that in userspace is not the issue? You are right. I wrote simple script for this already.
