Hi:
I'm trying to get an understanding of how the DSS works. My first
step is to reproduce the examples in .../Documentation/arm/OMAP/DSS.
When mapping fb0 to both overlay 0 and 1 you do:
ovl0=/sys/devices/platform/omapdss/overlay0
ovl1=/sys/devices/platform/omapdss/overlay1
fb0=/sys/class/graphics/fb0
fb1=/sys/class/graphics/fb1
echo "0" > $ovl0/enabled
echo "0" > $ovl1/enabled
echo "" > $fb1/overlays
echo "0,1" > $fb0/overlays
The two overlays get disabled:
# cat $ovl0/enabled
0
0# cat $ov10/enabled
0
But the frame buffers don't change overlays:
fb0# cat overlays
0
fb0# cat ../fb1/overlays
1
What's up?
