Hi all, I am working on STB7100 reference board and using STLinux2.2. The precompiled driver does not seem to be supporting hardware acceleration. I was trying to test the Enlightenment Foundation Libraries on it but according to the benchmark results i got by using expedite(Expedite is the benchmark program of Evas),shows me that there is no difference between using hardware on and software on. Whenever i changed the value at the directfbrc to no-software, i started to get warning messages.
#df_particle (!!!) *** WARNING [Ignoring draw (1) to RGB16, flags 0x00000001] *** [generic.c:6377 in gAcquire()] (!!!) *** WARNING [Ignoring draw (1) to RGB16, flags 0x00000001] *** [generic.c:6377 in gAcquire()] (!!!) *** WARNING [Ignoring draw (1) to RGB16, flags 0x00000001] *** [generic.c:6377 in gAcquire()] and benchmark never starts.

". Anybody had experience with the same problem with me? Is the STLinux2.2 built in driver really not supporting hardware acceleration and what should be done for that? I thought cross compiling a never version but when i tried a regular DirectFB 1.2.7 source i didn't see any gfx driver related with SThardware. Thanx. -- Oğuz Yarımtepe www.loopbacking.info
