Installation
By default, the MTRR size is not set correctly and the MDS bug is present. To set the MTRR size correctly and avoid memory loss, set the following kernel parameters:
enable_mtrr_cleanup mtrr_spare_reg_nr=1 mtrr_gran_size=32M mtrr_chunk_size=128M
To mitigate MDS, add mds=full,nosmt. The nosmt option disables simultaneous multi-threading so if the decrease in performance is too much, use mds=full instead.
