DYNAMIC_ATTRIBUTE

Consumer: proc_pcbs_init.C

Establishes the Pstate that the core chiplet will take on if:
psafe less-than-or-equal PMSR[global_actual_pstate]
AND any of the following conditions are true:
Loss of OCC Heartbeat if occ_heartbeat_en is set
PMGP0[force_safe_mode] is set

If psafe greater-than PMSR[global_actual_pstate], the  global_actual_pstate is forced.

The value of Psafe needs to be at or below the nominal Pstate to make sure safe operation of all chiplets.

      0x00001 - 0x1FFFF: value = number of ~100ns_hang_pulses
      For values greater than 0x00000, the actual delay is 1 PSS Clock + the
      time delay designated by the value defined. Max. delay at
      0x1FFFF: 13.1ms + 1 PSSI clock cycle.

      PROC_CHIP Attribute
      Receive PBAX Broadcast Group. Vector that is indexed when decoded PMISC
      pbax_type=broadcast with the decoded PMISC pbax_chipid value.  If the
      bit in this vector at the decoded bit location is a 1, then this receive
      engine will participate in the broadcast operation.

    <description>
      SYSTEM Attribute
      Maximum frequency (binary in MHz) that any processor in the system will
      run. Used to define the top end of the PState range in the frequency space.
      From this, the ATTR_PROCPM_PSTATE0_FREQUENCY is computed using
      ATTR_SYSTEM_REFCLK_FREQUENCY to determine the step size.

      Consumers: proc_build_gpstate_table.C (among others)

      Data is is provided by MVPD #V and is calculated as the minimum
      of the turbo frequencies

      Regardless of this attribute value, groups of size 1, 3, and 6
      will be forced to 128B stride based on the logic capabilities.

    <description>
      A bit vector (per Dean's request) specifying if a DIMM is functional.
      DIMM attributes, such as SIZE, are qualified by this bit vector.
      The attribute ANDed 0x80 means port 0, DIMM 0 is functional, 0x40 means port 0, DIMM 1 is functional.
      0x08 means port 1, DIMM 0 is functional and 0x04 means port 1 DIMM 1 is functional.
      A fully populated system would have the value of 0xCC.
      Used in various locations and is computed in mss_eff_cnfg.
      Each memory channel will have a value. creator: mss_eff_cnfg consumer: various firmware notes: none
      This factors in functionality

        as the WR 2D VREF HW cal depends upon WRITE_CTR 1D to function.

        Note: LRDIMM steps will only be enabled for LRDIMMs and won't run on RDIMMs.

    <id>MEMVPD_POS</id>
    <description>
      The position of the MCS target's VPD selector data, relative to the EEPROM
      that contains its data.  The VPD defition supports up to 16 values per
      EEPROM.
      For systems with an EEPROM per chip, this value should be equivalent to
      ATTR_CHIP_UNIT_POS.
      For systems with a single EEPROM for all chips, the value should follow
      the physical position in such a way to fit within the 16 available slots.

        Source: MRW: Downstream MSB Swap and Upstream MSB Swap
        Usage:  TX_MSBSWAP initfile setting for DMI and A buses

        This attribute represents whether or not a single clock group bus such as DMI and A bus was wired by the board designer using a feature
        called MSB Swap where lane 0 of the TX chip wires to lane n-1 on the RX chip where 'n' is the width of the bus. A basic description
        of this capability is that the board designer can save layers on the board wiring by crossing the wiring between the two chips in
        a prescribed manner. In a non-MSB Swapped bus Lane 0 on the TX chip wires to lane 0 on the RX chip, lane 1 to lane 1 and so on.
        If a bus is MSB Swapped then lane 0 of the TX chip wires to lane 'n-1' of the RX chip, lane 1 to lane 'n-2', etc. Random or
        arbitrary wiring of TX to RX lanes on different chips is NOT ALLOWED.

        The Master Chip of two connected chips is defined as the chip with the smaller value of (100*Node + Pos).
        The Slave Chip of two connected chips is defined as the chip with the larger value of (100*Node + Pos).
        The Downstream direction is defined as the direction from the Master chip to the Slave chip.
        The Upstream direction is defined as the direction from the Slave chip to the Master chip.

        The Downstream TX_MSBSWAP from the MRW is a uint8 value. 0x01 means the Downstream bus is wired msb to lsb etc. and
        0x00 means the bus is wired normally, msb to msb, lsb to lsb (lane0 to lane0).

        The Upstream TX_MSBSWAP from the MRW is a uint8 value. 0x01 means the Upstream bus is wired msb to lsb etc. and
        0x00 means the bus is wired normally, msb to msb, lsb to lsb (lane0 to lane0).

        It is up to the platform code to set up each ATTR_EI_BUS_TX_MSBSWAP value for the correct target endpoints.

        Measured in 100's.  So the value of 100 is one percent increase.
        This frequency change comes from changing multipliers and dividers to
        get the desired frequency. The supported frequencies come from
        Tim Diemoz.
        Creator: platform set this to 0.  Users can set this to a valid value.
        VALID Values: (TBD % to TBD %) (Tuleta) (TBD % to TBD %) (Glacier)
        Set by: PLL settings written by Dave Cadigan

    <id>PROC_PCIE_LANE_MASK</id>
    <description>Effective PCIE Lane Mask
        Creator: Firmware
        Purpose: Holds the effective PCIE lane mask of each PEC after taking
            into account any IOP bifurcations. If no IOP bifurcations present,
            this is just the value of the PEC_PCIE_LANE_MASK_NON_BIFURCATED
            attribute
        Data Format: x4 array of uint16_t values.  The uint16_t value is a
            mask for lane 0, the next for lane 1 and so on until lane 3.
            A lane set mask indicates which groups of lanes are assigned to an
            IOP.  For instance, lane set 0 value of 0xFFFF and lane set 1 value
            of 0x0000 for PEC0 means PEC0 is a x16. Lane set 0 value of 0xFF00
            and lane set 1 value of 0x00FF for PEC0, means the IOP is bifurcated
            into two x8s.

            instance, lane set 0 value of 0xFFFF and lane set 1 value of 0x0000
            means the PEC is a x16. Lane set 0 value of 0xFF00 and lane
            set 1 value of 0x00FF, means the PEC is split into two x8s.

    <description>Indicates whether PCIE lanes terminate at a pluggable slot
        Creator: MRW
        Purpose: Used by FW to know whether the given PCIE lanes terminate at a
            pluggable slot or not.  If this is the case, and the platform
            supports bifurcation, the card's VPD should be interrogated to
            determine whether to bifurcate the IOP or not.
        Data Format: x4 array of uint8_t values.  The first value indicates
            whether lane set 0 terminates at a pluggable slot.  The
            next three values indicate the same for lane sets 1-3. A value of
            1 at a given array index indicates the lanes terminate at a
            pluggable slot, 0 otherwise.

    <description>
      Specify the system policy to enforce synchronous mode between memory and
      nest. This drives the value of ATTR_MC_SYNC_MODE.
        0 = UNDETERMINED : Run synchronously if the dimm and nest freq matches
        1 = ALWAYS : Require matching frequencies and deconfigure memory that
                     does not match the nest
        2 = NEVER : Do not run synchronously, even if the frequencies match

    <id>MAX_ALLOWED_DIMM_FREQ</id>
    <description>
      Maximum frequency (in MHz) that this system can run the DIMMs at.
      There are 5 possible values determined by the dimm configuration.
      For configurations which have mixed rank configurations, the lowest
      frequency based on ranks of either DIMM is chosen. For example if
      there was a 1R and a 2R DIMM installed, and 1R dual drop was a lower
      max freq than 2R dual drop, then the 1R max freq would be the max allowed.
      [0]=One rank, single drop
      [1]=Two rank, single drop
      [2]=Four rank, single drop
      [3]=One rank, dual drop
      [4]=Two rank, dual drop
      A value of zero would indicate an unsupported configuration.

      Voltage (binary in 1mV units) to apply to the VDN VRM for booting.  Value
      chosen is system dependent and is a combination of the part's Vital Product
      Data (VPD) (typically the PowerSave value) and the minimum allowed for
      correct operation of the fabric bus.

    <description>
      Logical position of target within a system. This is derived from the SMP location
      of each processor and each target's relationship to a proc.
      - PROC = based on SMP groupid+chipid
      - MEMBUF = PROC:FAPI_POS * [max membuf per proc]
      - 1st level child unit = [parent chip]:FAPI_POS * [max children of this type per chip]
      - 2nd+ level child unit = [immediate parent unit]:FAPI_POS * [max units below parent]
      Note: This should not be used algorithmically by HWPs directly.
      Note: Value ignores physical drawer boundaries, the value is unique across the entire
            system.
      This data is derived from the MRW.
      Default of NA is 0xFFFFFFFF (to avoid confusion with legitimate 0
         values)

    Array of L3 Clock strength values to be used going between "High and Normal

    ATTR_RESCLK_L3_VOLTAGE_THRESHOLD_MV.

    Entry 0 = "High and Normal Voltage" setting
    Entry 3 = "High and Normal Voltage" setting

    Entry 1 = transitional setting defined by the clock team
    Entry 2 = transitional setting defined by the clock team

    Contents of each entry will be written directly into L3 control bits in the
    QACCR(16:23) a RMW operations.  If the circuits demand a grey code whereby
    only 1 bit of this field can change at a time, the entries must be deal with
    such encoding.  The Hcode that these values does not perform that function;
    it merely steps from 0->3 when going below the voltage defined by
    ATTR_RESCLK_L3_VOLTAGE_THRESHOLD_MV and then steps 3->0 when going at or
    above the voltage defined by ATTR_RESCLK_L3_VOLTAGE_THRESHOLD_MV.

            That is, all of the set bits will be calibrated for all DP16. A value
            of zero indicates the calibration should not be run.

      Defines the maximum Seeprom storage size for the fully-customized SBE image

      For platforms (FSP/HB FW) which require the image to be constrained into a
      physical storage device (SEEPROM), this should reflect the maximum size of that
      memory (e.g., 256KB).
      For platforms (Cronus) which may use a customized image in a virtual
      envrionment with no physical storage constraints, this size may be
      larger than the physical SEEPROM size.
