    <description>System attribute. If all MCS chiplets are in an interleaving group (1=true, 0=false). - If true the SMP fabric is setup in normal mode and multiple MCSs are grouped (disallowing systems with memory only under 1 MCS (i.e. systems with a single C-DIMM)) - If false the SMP fabric is setup in checkerboard mode. Provided by the Machine Readable Workbook. This attribute is based on Machine-Type-Model (MTM) and is setup by the service processor.</description>

    <description>EQ boot frequency multiplier The equation for this setting is BOOT_FREQ(MHz)/(REFCLK/DPLL_DIVIDER) where the DPLL DIVIDER is planned for being set to 8. The value needs to be loaded right justified. The value's right most 11 bits (becoming 0:10) is written as bits 17:27 of PPM DPLL freq ctrl register. Bits 0:7 become DPLL.MULT_INTG(0:7) and bits 8:10 are DPLL.MULT_FRAC(0:2). As an example: 3000MHz / (133MHz/8) = 3000 / 16.667 = ~180 =&gt; 0xB4</description>

    <description>Source: MRW: Downstream MSB Swap and Upstream MSB Swap Usage: TX_MSBSWAP initfile setting for DMI and X buses This attribute represents whether or not a single clock group bus such as DMI and X 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.</description>

    <description>Designates the speed at which a given I2C bus should run. Creator: MRW Purpose: Used by FW to know the fastest possible bus speed that all of the devices on a given bus are able to use. Data Format: 4x13 array of uint16_t values. The first index indicates the engine number of the bus. The second index indicates the port number of the bus. The value in the array is the I2C bus speed used for that engine/port combination in KHz.</description>

    <description>This attribute provides a place for Hostboot to save off the IO_OLLFIR_MASK. During IPL time Hostboot wants to change the value of the FIR but it will write the value back during Hostboot Runtime (HBRT). Hostboot will need to wait to save the values until after p9_chiplet_scominit is called because that HWP sets the fir masks we want to save off. Values will need to restored after the PEER_TARGET values have been updated in HBRT</description>

    <description>This attribute provides a place for Hostboot to save off the PB_IOOFIR_MASK. During IPL time Hostboot wants to change the value of the FIR but it will write the value back during Hostboot Runtime (HBRT). Hostboot will need to wait to save the values until after p9_chiplet_scominit is called because that HWP sets the fir masks we want to save off. Values will need to restored after the PEER_TARGET values have been updated in HBRT</description>

    <description>OMI inband BAR address offset. Set by platform. One Axone bar register is set per MC channel for MMIO and another is set per MC channel for config space. The bar is shared between both sub-channels each with an OCMB. The upper bit of the bar size is used to determine which sub-channel is selected. This means that for two OCMB's their config space is contiguous and their MMIO space is contiguous. Therefore a single OCMB's MMIO and config space cannot be contiguous. However, we can still use one BAR attribute. The p9a_omi_setup_bars procedure can interleave the config space and MMIO space as shown in the table bellow. For example, both MMIO and config bar sizes are 2GB. The 2GB bit becomes the selector for the subchannel. The 4GB bit becomes the offset applied for MMIO operations. Value is also set on MC to match the BAR offset of the child OMI with lowest chip unit. Each OCMB is assigned one base address attribute. ocmb | BAR ATTRIBUTE | Type | Base reg - end addr | size | sub-ch +-----+--------------------+------+-----------------------------------------+------+------- ocmb0 | 0x0006030200000000 | cnfg | 0x0006030200000000 - 0x000603027FFFFFFF | 2GB | 0 ocmb1 | 0x0006030280000000 | cnfg | 0x0006030280000000 - 0x00060302FFFFFFFF | 2GB | 1 ocmb0 | N/A | mmio | 0x0006030300000000 - 0x000603037FFFFFFF | 2GB | 0 ocmb1 | N/A | mmio | 0x0006030380000000 - 0x00060303FFFFFFFF | 2GB | 1 +-----+--------------------+------+-----------------------------------------+------+------- ocmb2 | 0x0006030400000000 | cnfg | 0x0006030400000000 - 0x000603047FFFFFFF | 2GB | 0 ocmb3 | 0x0006030480000000 | cnfg | 0x0006030480000000 - 0x00060304FFFFFFFF | 2GB | 1 ocmb2 | N/A | mmio | 0x0006030500000000 - 0x000603057FFFFFFF | 2GB | 0 ocmb3 | N/A | mmio | 0x0006030580000000 - 0x00060305FFFFFFFF | 2GB | 1 Used by p9a_omi_setup_bars</description>

    <description>Effective PCIE IOP reversal configuration Creator: Firmware Purpose: Holds the effective PCIE IOP reversal value after taking into account any IOP bifurcations. If no IOP bifurcations present, this is just the value of the PROC_PCIE_IOP_REVERSAL_NON_BIFURCATED attribute. Data Format: x4 array of uint8_t values. The first uint8_t value is for lane set 0, the second for lane set 1 and so on. The given index in the array is a mask which specifies which bit to invert in the lane swap settings for the given PEC/lane set.</description>

    <description>Bifurcated PCIE IOP swap configuration value Creator: MRW Purpose: Holds the base IOP swap configuration value for the IOPs in the case where they are bifurcated. The swap value controls how PCIE lanes are recordered when the leave the IOP, to provide lane routing flexibility. Data Format: A uint8_t value. The value specifices for the hardware how to swap the PCIE lanes for the given PEC.</description>

    <description>PCIE Lane Mask bifurcated configuration Creator: MRW Purpose: Holds the PCIE lane mask assuming IOPs are bifurcated. Data Format: x4 array of uint16_t values. The first uint8_t value is lane set 0, the second for lane set 2 and so on. A lane set mask indicates which groups of lanes are assigned to an IOP. For instance, lane set 0 value of 0xFF00 and lane set 1 value of 0x00FF means the IOP is bifurcated into two x8s.</description>

    <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>

    <description>This field is of the form ?vendor,type? where the type indicates a type of system within the System Family. The textual portion of the string has a maximum length of 63 characters to accommodate a terminating NULL. Both vendor and name fields are lower case US ASCII. No special characters other than ",", "-", and "+" as described below should be used in the string. If identification of specific models within a system type is desired, "-model" should be appended to the end of the name. The "-model" portion is optional and could be used to identify the packaging, specific model numbers, etc. NOTE: No Hostboot code should ever key off of this value.</description>
