The GICDST_SGI_CTL.TRGLSTFILT bit field determines how the distributor
must process the requested SGI.
CPU Target list.
When the GICDST_SGI_CTL.CPUTRGTLST bit field TargetList Filter = 0b00, de-
fines the CPU interfaces to which the Distributor must forward the interrupt.
Each bit of the GICDST_SGI_CTL.CPUTRGTLST bit field refers to the corre-
sponding CPU interface, for example CPUTargetList[0] corresponds to CPU interface
0. Setting a bit to 1 indicates that the interrupt must be forwarded to the correspond-
ing interface. If this field is 0x00 when TargetListFilter is 0b00, the Distributor does
not forward the interrupt to any CPU interface.
