Definition at line 96 of file ProcessorBind.h.

MAX_ADDRESS

#define MAX_ADDRESS   0xFFFFFFFFFFFFFFFFULL

Maximum legal RV64 address.

Definition at line 101 of file ProcessorBind.h.

MAX_ALLOC_ADDRESS

#define MAX_ALLOC_ADDRESS   0xFFFFFFFFFFFFULL

Maximum usable address at boot time (48 bits using 4 KB pages in Supervisor mode)

Definition at line 106 of file ProcessorBind.h.

MAX_INTN

#define MAX_INTN   ((INTN)0x7FFFFFFFFFFFFFFFULL)

Maximum legal RISC-V INTN and UINTN values.

Definition at line 111 of file ProcessorBind.h.

MAX_UINTN

#define MAX_UINTN   ((UINTN)0xFFFFFFFFFFFFFFFFULL)

Definition at line 112 of file ProcessorBind.h.

CPU_STACK_ALIGNMENT

#define CPU_STACK_ALIGNMENT   16

The stack alignment required for RISC-V.

Definition at line 117 of file ProcessorBind.h.

DEFAULT_PAGE_ALLOCATION_GRANULARITY

#define DEFAULT_PAGE_ALLOCATION_GRANULARITY   (0x1000)

Page allocation granularity for RISC-V.

Definition at line 122 of file ProcessorBind.h.

RUNTIME_PAGE_ALLOCATION_GRANULARITY

#define RUNTIME_PAGE_ALLOCATION_GRANULARITY   (0x1000)

Definition at line 123 of file ProcessorBind.h.

EFIAPI

#define EFIAPI

The default for a non Microsoft* or GCC compiler is to assume the EFI ABI is the standard.

Definition at line 149 of file ProcessorBind.h.

FUNCTION_ENTRY_POINT

#define FUNCTION_ENTRY_POINT

(

FunctionPointer

)

Value:

(VOID *)(UINTN)(FunctionPointer)

Return the pointer to the first instruction of a function given a function pointer.

On x64 CPU architectures, these two pointer values are the same, so the implementation of this macro is very simple.

Parameters

FunctionPointer

A pointer to a function.

Returns

The pointer to the first instruction of a function given a function pointer.
