/* Each build option listed here is packed into a dword which
 * provides up to log2(RGX_BUILD_OPTIONS_MASK_KM + 1) flags for KM 
 * and (32 - log2(RGX_BUILD_OPTIONS_MASK_KM + 1)) flags for UM.
 * The corresponding bit is set if the build option
 * was enabled at compile time.
 *
 * In order to extract the enabled build flags the INTERNAL_TEST
 * switch should be enabled in a client program which includes this
 * header. Then the client can test specific build flags by reading
 * the bit value at ##OPTIONNAME##_SET_OFFSET in RGX_BUILD_OPTIONS_KM 
 * RGX_BUILD_OPTIONS.
 *
 * IMPORTANT: add new options to unused bits or define a new dword
 * (e.g. RGX_BUILD_OPTIONS_KM2 or RGX_BUILD_OPTIONS2) so that the bitfield 
 * remains backwards
 * compatible.
