Installation
By default, MTRR size is not set correctly and MDS bug is present. To set the MTRR size correctly and avoid memory loss, add enable_mtrr_cleanup mtrr_spare_reg_nr=1 mtrr_gran_size=32M mtrr_chunk_size=128M to your kernel parameters. And to mitigate MDS, add mds=full,nosmt to kernel parameters. nosmt option disables simultaneous multithreading so if the performance decrease is too much, add mds=full instead.
