Macro Definition Documentation

◆ MDE_CPU_RISCV64

#define MDE_CPU_RISCV64

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

Definition at line 18 of file ProcessorBind.h.

◆ MAX_BIT

#define MAX_BIT 0x8000000000000000ULL

A value of native width with the highest bit set.

Definition at line 91 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 95 of file ProcessorBind.h.

◆ MAX_ADDRESS

#define MAX_ADDRESS 0xFFFFFFFFFFFFFFFFULL

Maximum legal RV64 address.

Definition at line 100 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 105 of file ProcessorBind.h.

◆ MAX_INTN

#define MAX_INTN ((INTN)0x7FFFFFFFFFFFFFFFULL)

Maximum legal RISC-V INTN and UINTN values.

Definition at line 110 of file ProcessorBind.h.

◆ MAX_UINTN

#define MAX_UINTN ((UINTN)0xFFFFFFFFFFFFFFFFULL)

Definition at line 111 of file ProcessorBind.h.

◆ CPU_STACK_ALIGNMENT

#define CPU_STACK_ALIGNMENT 16

The stack alignment required for RISC-V.

Definition at line 116 of file ProcessorBind.h.

◆ DEFAULT_PAGE_ALLOCATION_GRANULARITY

#define DEFAULT_PAGE_ALLOCATION_GRANULARITY (0x1000)

Page allocation granularity for RISC-V.

Definition at line 121 of file ProcessorBind.h.

◆ RUNTIME_PAGE_ALLOCATION_GRANULARITY

#define RUNTIME_PAGE_ALLOCATION_GRANULARITY (0x1000)

Definition at line 122 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 148 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 169 of file ProcessorBind.h.

◆ __USER_LABEL_PREFIX__

#define __USER_LABEL_PREFIX__

Definition at line 172 of file ProcessorBind.h.

Typedef Documentation

◆ attribute

typedef INT64 INTN __attribute__((aligned(8)))

8-byte unsigned value

Signed value of native width.

Unsigned value of native width.

2-byte signed value

2-byte Character.

2-byte unsigned value

4-byte signed value

4-byte unsigned value

8-byte signed value

Unless otherwise specified all strings are stored in the UTF-16 encoding format as defined by Unicode 2.1 and ISO/IEC 10646 standards.

(4 bytes on supported 32-bit processor instructions, 8 bytes on supported 64-bit processor instructions)

Definition at line 30 of file ProcessorBind.h.

◆ BOOLEAN

typedef unsigned char BOOLEAN

Logical Boolean.

1-byte value containing 0 for FALSE or a 1 for TRUE. Other values are undefined.

◆ INT8

typedef signed char INT8

1-byte signed value

Definition at line 72 of file ProcessorBind.h.
