Problem with DSS2 - cannot set virtual resolution

GoogleGroups

Hello,

I am using the lastest kernel from Tomab
(http://www.bat.org/~tomba/git/linux-omap-dss.git/) and I am not able
to change the virtual resolution.

I attach a program which shows the error. FBIOPUT_VSCREENINFO does not
fail but the virt. resolution does not change. FBIOPAN_DISPLAY gives
an error....
I use DSS2 at 640x480:

# fbset
mode "640x480-59"
        # D: 23.500 MHz, H: 29.375 kHz, V: 58.986 Hz
        geometry 640 480 640 480 32
        timings 42553 48 80 3 11 32 4
        accel false
        rgba 8/16,8/8,8/0,0/0
endmode

Any ideas?

Hello,

with a lot of help from Tomba I could solve this problem. One has to
increase the memory with OMAPFB_QUERY_MEM. Before that the plane has
to disabled and after the of course enabled again.
