I want to port Xfbdev Xserver to ARM 11 DTV board . i have some issues as below
Issue 1: i am able to get only 24 bit data RGB data (eventhough depth is set as 32 bit) & unable to receive alpha value, hence my graphics screen creates hole . if i add some patches in bitblt.c (dst* | 0xff000000) for ARGB data & make it opaque everything seems to be fine. As i need transparency set by client applications kindly let me know the proper solution which can work wiothout patches.
Issue 2: For running OpenGL applications using mesalib GLX support (DRI is not suitable due to some hardware issues) while GLXgears or any opengl sample application, background drawing seems to be ok but vertex drawing shows black screen. i have upgraded mesalib with latest version but problem remains same. Kindly let me know solution . i read somewhere regarding bug in mesalib.
Issue3: performance of Xserver booting time, drawing latency etc seems to be very high , can somebody help me regarding optimization points to make performance better. i read about shared memory transport created by SGI or HP as i understand performance issue is due to its client server architecture ( MIT -SHM is already added for images). Kindly help me out to provide good optimization points in a DTV standalone system. current transport used is unix domain sockets but performance is not acceptable.
I am newbie & i need to prove TinyX capablility on ARM11 DTV hardware in this sprint & have very less time. i hope to get some useful suggestions . Thanks to all in advance. Pls let me know if i need to post my query in any other list.
Best Regards
