You are right, I compared the DFB sources released by Siemens with
original and they differ:
they added in fbdev.c primaryAllocateSurface()
caps |= config->surface_caps & DSCAPS_PREMULTIPLIED;
+ caps |= DSCAPS_SEPARATED;
I made this change too, and the video mode probs are gone.
I tried to add DSCAPS_SEPARATED in my app source, not in the driver:
DFBSurfaceDescription dscPrimary;
dscPrimary.flags = (DFBSurfaceDescriptionFlags)(DSDESC_CAPS |
DSDESC_PIXELFORMAT);
dscPrimary.caps = (DFBSurfaceCapabilities)(DSCAPS_PRIMARY|
DSCAPS_SEPARATED);
dscPrimary.pixelformat = DSPF_ARGB1555;
DFBCHECK( dfb->CreateSurface(dfb, &dscPrimary, &primary) );
but this will not work. Why?
An other problem is, that I implemented an info ticker with DrawGlyph,
but this does not works anymore. Are there any incompatible changes
between 0.9.18 and 0.9.25.1?
Thanks for help
Ciao,
Dirk
