- store surface state info for bindless addressing in graphics allocation - remove map in BindlessHeapsHelper - bindlessInfo is constant for the lifetime of an allocation - program bindless offsets and surface states for images when used in bindless kernel - handle ouf of memory on surface state heap - return error Related-To: NEO-7063 Signed-off-by: Mateusz Hoppe <mateusz.hoppe@intel.com>
