Macro Definition Documentation

◆ __USER_LABEL_PREFIX__

#define __USER_LABEL_PREFIX__

Definition at line 170 of file ProcessorBind.h.

◆ CPU_STACK_ALIGNMENT

#define CPU_STACK_ALIGNMENT 16

The stack alignment required for RISC-V

Definition at line 114 of file ProcessorBind.h.

◆ DEFAULT_PAGE_ALLOCATION_GRANULARITY

#define DEFAULT_PAGE_ALLOCATION_GRANULARITY (0x1000)

Page allocation granularity for RISC-V

Definition at line 119 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 146 of file ProcessorBind.h.

◆ FUNCTION_ENTRY_POINT

#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.

Definition at line 167 of file ProcessorBind.h.

◆ MAX_2_BITS

#define MAX_2_BITS 0xC000000000000000ULL

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

Definition at line 93 of file ProcessorBind.h.

◆ MAX_ADDRESS

#define MAX_ADDRESS 0xFFFFFFFFFFFFFFFFULL

Maximum legal RV64 address

Definition at line 98 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 103 of file ProcessorBind.h.

◆ MAX_BIT

#define MAX_BIT 0x8000000000000000ULL

A value of native width with the highest bit set.

Definition at line 89 of file ProcessorBind.h.

◆ MAX_INTN

#define MAX_INTN ((INTN)0x7FFFFFFFFFFFFFFFULL)

Maximum legal RISC-V INTN and UINTN values.

Definition at line 108 of file ProcessorBind.h.

◆ MAX_UINTN

#define MAX_UINTN ((UINTN)0xFFFFFFFFFFFFFFFFULL)

Definition at line 109 of file ProcessorBind.h.

◆ MDE_CPU_RISCV64

#define MDE_CPU_RISCV64

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

Definition at line 16 of file ProcessorBind.h.

◆ RUNTIME_PAGE_ALLOCATION_GRANULARITY

#define RUNTIME_PAGE_ALLOCATION_GRANULARITY (0x1000)

Definition at line 120 of file ProcessorBind.h.
