IMX28: writing directly to a layer surface
I created a 24 BPP surface using gf_surface_create_layer, specifying CPU_LINEARLY_ACCESSIBLE, and verified that the
surface does indeed have this flag set in the surface_info_t.
However, when I try and write to the surface, the access does not appear to be linear. It seems as though there is a
swizzle or address redirection occurring. Drawing to a 32 bit surface and then using gf_draw_blit to blit to the 24 BPP
layer_surface has the same issue.
Is it possible to write linearly (with the CPU) to a displayable surface on this chipset?
