PLIC Base Address.

Definition at line 70 of file core_feature_plic.h.

◆ PLIC_CLAIM_OFFSET

#define PLIC_CLAIM_OFFSET _AC(0x200004,UL)

PLIC Claim register offset.

Definition at line 60 of file core_feature_plic.h.

◆ PLIC_CLAIM_REGADDR

#define PLIC_CLAIM_REGADDR ( ctxid ) ((PLIC_BASE) + (PLIC_CLAIM_OFFSET) + ((ctxid) << PLIC_CLAIM_SHIFT_PER_CONTEXT))

Definition at line 95 of file core_feature_plic.h.

◆ PLIC_CLAIM_SHIFT_PER_CONTEXT

#define PLIC_CLAIM_SHIFT_PER_CONTEXT 12

PLIC Claim register offset shift per context.

Definition at line 62 of file core_feature_plic.h.

◆ PLIC_COMPLETE_REGADDR

#define PLIC_COMPLETE_REGADDR ( ctxid ) (PLIC_CLAIM_REGADDR(ctxid))

Definition at line 96 of file core_feature_plic.h.

◆ PLIC_ENABLE_OFFSET

#define PLIC_ENABLE_OFFSET _AC(0x2000,UL)

PLIC Enable register offset.

Definition at line 56 of file core_feature_plic.h.

◆ PLIC_ENABLE_REGADDR

#define PLIC_ENABLE_REGADDR	(	ctxid,
		source
	)	((PLIC_BASE) + (PLIC_ENABLE_OFFSET) + ((ctxid) << PLIC_ENABLE_SHIFT_PER_CONTEXT) + ((source) >> 5) * 4)

Definition at line 93 of file core_feature_plic.h.

◆ PLIC_ENABLE_SHIFT_PER_CONTEXT

#define PLIC_ENABLE_SHIFT_PER_CONTEXT 7

PLIC Enable register offset shift per context.

Definition at line 57 of file core_feature_plic.h.

◆ PLIC_GetHartID

#define PLIC_GetHartID ( ) (__get_hart_index())

PLIC_GetHartID() is used to get plic hartid which might not be the same as cpu hart id, for example, cpu hartid may be 1, but plic hartid may be 0, then plic hartid offset is 1.

If defined __PLIC_HARTID, it will use __PLIC_HARTID as plic hartid, otherwise, it will use __get_hart_index(). The cpu hartid is get by using __get_hart_id function
