Hi, guys,
Now I am researching about allocate the video overlay memory,
some confuse to inquire.
In xf86-video-geode -> lx_video.c -> LXInitOffscreenImages:
alloc_surface = LXAllocateSurface;
free_surface = LXFreeSurface;
In xf86-video-ati -> radeon_video.c ->
RADEONInitOffscreenImages:
alloc_surface = RADEONAllocateSurface;
free_surface = RADEONFreeSurface;
Inquire: what kind of situation trigger above functions? What
are the mainly effect?
Thanks,
Hunk Cui
