The ICV_AP0R0_EL1 register provides information about virtual Group 0 active priorities.
This register is a 32-bit register and is part of the virtual GIC system registers functional group.
The core implements 5 bits of priority with 32 priority levels, corresponding to the 32 bits [31:0] of the register. The possible values for each bit are:
0x00000000 | No interrupt active. This is the reset value. |
0x00000001 | Interrupt active for priority 0x0 . |
0x00000002 | Interrupt active for priority 0x8 . |
... | |
0x80000000 | Interrupt active for priority 0xF8 . |
