#define __USER_LABEL_PREFIX__

#define ASM_GLOBAL .globl

For GNU assembly code, .global or .globl can declare global symbols. Define this macro to unify the usage.

#define CPU_STACK_ALIGNMENT 16

The stack alignment required for RISC-V

#define DEFAULT_PAGE_ALLOCATION_GRANULARITY (0x1000)

Page allocation granularity for RISC-V

#define EFIAPI

Define the standard calling convention regardless of optimization level The GCC support assumes a GCC compiler that supports the EFI ABI. The EFI ABI is much closer to the x64 Microsoft* ABI than standard x64 (x86-64) GCC ABI. Thus a standard x64 (x86-64) GCC compiler can not be used for x64. Warning the assembly code in the MDE x64 does not follow the correct ABI for the standard x64 (x86-64) GCC.

#define FUNCTION_ENTRY_POINT ( FunctionPointer ) (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.

#define MAX_2_BITS 0xC000000000000000ULL

A value of native width with the two highest bits set.

#define MAX_ADDRESS 0xFFFFFFFFFFFFFFFFULL

Maximum legal RV64 address

#define MAX_ALLOC_ADDRESS 0xFFFFFFFFFFFFULL

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

#define MAX_BIT 0x8000000000000000ULL

A value of native width with the highest bit set.

#define MAX_INTN ((INTN)0x7FFFFFFFFFFFFFFFULL)

Maximum legal RISC-V INTN and UINTN values.

#define MAX_UINTN ((UINTN)0xFFFFFFFFFFFFFFFFULL)

#define MDE_CPU_RISCV64

Define the processor type so other code can make processor based choices

#define RUNTIME_PAGE_ALLOCATION_GRANULARITY (0x1000)
