Several scenarios of dark matter alternative to the Cold Dark Matter paradigm predict a suppression of the halo mass function at low halo masses. This has strong implications for the early abundance of faint galaxies as well as the process of cosmic reionisation. In this talk I will discuss constraints from recent observations of the high-z universe on a large class of DM models characterized by a small-scale cut-off in the linear power spectrum.
