What kind of your board is?
I think if you want to get the H/w graphic acceleration.Your should find the 
overlay layer first.If it support overlay and not simulate it by sofware,then 
the H/w graphic acceleration works.

Hello List, 

I am trying to understand the "fbdev" implementation to enable H/W 
acceleration on my board. 

I found the "FBDevDGAFunctions" variable which I think might be used for 
enabling H/W accelaration. This variable is declared in 
xorg/sources/build/programs/Xserver/hw/xfree86/drivers/fbdev/fbdev.c file as 
follows 

static DGAFunctionRec FBDevDGAFunctions = 
{ 
FBDevDGAOpenFramebuffer, 
NULL, /* CloseFramebuffer */ 
FBDevDGASetMode, 
FBDevDGASetViewport, 
FBDevDGAGetViewport, 
NULL, /* Sync */ 
NULL, /* FillRect */ 
NULL, /* BlitRect */ 
NULL, /* BlitTransRect */ 
}; 

I have modified the above strucutre by replacing NULL with function names 
for FillRect, BlitRect and BlitTransRect. But Xserver is not calling these 
functions at all??? 


Can anyone suggest me what is going wrong?
