The GICR_PARTIDR characteristics are:
Sets the PARTID and PMG values used for memory accesses by the Redistributor.
This register is present only
when FEAT_GICv3p1GICv3.1 is implemented.
Otherwise, direct accesses to GICR_PARTIDR are RES0.
A copy of this register is provided for each Redistributor.
When GICR_TYPER.MPAM==0, this register is RES0.
GICR_PARTIDR is a 32-bit register.
The GICR_PARTIDR bit assignments are:
31 | 30 | 29 | 28 | 27 | 26 | 25 | 24 | 23 | 22 | 21 | 20 | 19 | 18 | 17 | 16 | 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
RES0 | PMG | PARTID |
Reserved, RES0.
PMG value used when Redistributor accesses memory.
It is IMPLEMENTATION DEFINED whether bits not needed to represent PMG values in the range 0 to PMG_MAX are stateful or RES0.
This field resets to 0.
PARTID value used when Redistributor accesses memory.
It is IMPLEMENTATION DEFINED whether bits not needed to represent PARTID values in the range 0 to PARTID_MAX are stateful or RES0.
This field resets to 0.
