I'm looking at the function void dfb_gfxcard_batchblit( DFBRectangle
*rects, DFBPoint *points, int num, CardState *state )
It appears that for the HW path all blits must succeed or none.
This is because
a) the SW path would (re)iterate all entries
b) and the var 'hw' is only returned from the last hw path blit anyway.
I have a surface format for which I may not be able to support overlapped
blits, I thought for BatchBlit I might have been able to punt just the ones
that overlapped.
It seems though that I will have to provide a BatchBlit function
handler/implementation and validate the whole list in my gfxdriver (for
this format) - punting all or none.
Is my conclusion correct?
TIA,
Jason Barstow
