    iommu/amd: Override wrong IVRS IOAPIC on Raven Ridge systems · 93d05155
    Kai-Heng Feng authored Aug 21, 2019
    Raven Ridge systems may have malfunction touchpad or hang at boot if
    incorrect IVRS IOAPIC is provided by BIOS.
    
    Users already found correct "ivrs_ioapic=" values, let's put them inside
    kernel to workaround buggy BIOS.
