Hi Pavel, The value is taken from the gic-500 document in the re-distributer's table (3-7). I don't know where the value 0x91 comes from as GICD_PIDR0 is 0x92, GICR_PIDR0 is 0x93 and GITS_PIDR0 is 0x94. In the GICv3 document section 5.4.21 it is also been written: 0xFFE0 GICR_PIDR0 Bits [7:0]. Bits [7:0] of the ARM-defined DevID field. This field is 0x93 in ARM implementations of a GICv3 or later Re-distributor. Best regards, S.P.
