Macro Definition Documentation

◆ PLIC_BASE

#define PLIC_BASE __PLIC_BASEADDR

PLIC Base Address.

Definition at line 121 of file core_feature_plic.h.

◆ PLIC_CLAIM_OFFSET

#define PLIC_CLAIM_OFFSET _AC(0x200004,UL)

PLIC Claim/Complete register offset.

Definition at line 111 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 152 of file core_feature_plic.h.

◆ PLIC_CLAIM_SHIFT_PER_CONTEXT

#define PLIC_CLAIM_SHIFT_PER_CONTEXT 12

log2(0x1000), shift per context

Definition at line 113 of file core_feature_plic.h.

◆ PLIC_COMPLETE_REGADDR

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

Definition at line 153 of file core_feature_plic.h.

◆ PLIC_ENABLE_OFFSET

#define PLIC_ENABLE_OFFSET _AC(0x2000,UL)

PLIC Enable register offset.

Definition at line 106 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 150 of file core_feature_plic.h.

◆ PLIC_ENABLE_SHIFT_PER_CONTEXT

#define PLIC_ENABLE_SHIFT_PER_CONTEXT 7

log2(0x80), shift per context

Definition at line 107 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
