why the inter-core SGI interrupt cannot be trigged on GICv3 hardware

My hareware environment:

1.  a ARMv8 processor , which  runs in 64bit EL3 and 32bit EL2&EL1.

2. a GICv3 interrupt controller

Running in 32bit hyp mode,  I try to send a SGI interrupt from core0 to core1, but core1 cannot receive this interrupt. Below are what I've tried.

1. I use ICC_SGI1R to send the interrupt. GICD_SGIR cannot be used because "affinity routing" is enabled.

2. Group0, Group1NS and Group1S interrupt are enabled in GICD_CTLR

3. Write GICR_ISENABLER0 to enable SGI interrupt

4. The IRQ/FIQ are unmasked in core1's cpsr
5. Group1 intersuprt is enabled in core1's ICC_IGRPEN1 register

But after writting to  ICC_SGI1R, I can not find valid bit in pending state register, and core1's ICC_IAR register are also always invalid.

Do you have any suggestions with this issue?

Thanks in advance.
