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()]

and benchmark never starts.
Below is the df_dok results:

When i made a test with df_particle the result was not as expected (after
writing "hardware" to directfbrc file instead of "no-software"), it was slow
and not smooth.
df_particle - a moving fountain consisting of alphablended rectangles,
nice and fast if hardware accelerated
I also read the thread here:
http://www.nabble.com/Performance-issue-with-STi7109-td14580428.html
It is written that "The ST people told us that the official stapi 2.2
framebuffer driver
doesn't support *DirectFB*... quite disappointing... ".
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.
