    target/ppc: Add POWER9/ISAv3.00 to compat_table · 9b44c836
    Suraj Jitindar Singh authored
    compat_table contains the list of logical pvr compat modes which a cpu can
    operate in. It is a list of struct CompatInfo which contains the given pvr
    value for a compat mode, the pcr bits which should be set to operate in
    that compat mode, the pcr level which must be present in pcr_supported for
    a processor to support that compat mode and the max threads possible in
    that compat mode.
    Add an entry for the POWER9/ISAv3.00 logical pvr which represents a
    processor running with support for logical pvr 0x0f000005. A processor
    running in this mode should have PCR_COMPAT_3_00 set in the pcr (if
    available in pcr_mask) and should have PCR_COMPAT_3_00 in pcr_supported
    to indicate that it is capable of running in this compat mode.
    Also add PCR_COMPAT_3_00 to the bits which must be set for all previous
    compat modes. Since no processor models contain this bit yet in pcr_mask
    it will never be set, but this ensures we don't forget to in the future.
