Data Structures

union  NvData32Rec
 Union that can be used to view a 32-bit word as your choice of a 32-bit unsigned integer, a 32-bit signed integer, or an IEEE single-precision float. More...
 
union  NvData64Rec
 Generic data representation for both 32 and 64 bits data. More...
 
struct  NvPointRec
 This structure is used to determine a location on a 2-dimensional object, where the coordinate (0,0) is located at the top-left of the object. More...
 
struct  NvPointF32Rec
 
struct  NvRectRec
 This structure is used to define a 2-dimensional rectangle where the rectangle is bottom right exclusive (that is, the right most column, and the bottom row of the rectangle is not included). More...
 
struct  NvRectF32Rec
 This structure is used to define a 2-dimensional rectangle relative to some containing rectangle. More...
 
struct  NvSizeRec
 This structure is used to define a 2-dimensional surface where the surface is determined by it's height and width in pixels. More...
 

Macros

#define NV_FORCE_INLINE   NV_FORCEINLINE
 Include headers that provide NULL, size_t, offsetof, and [u]intptr_t. More...
 
#define NV_ALIGN   NV_ALIGN_BYTES
 
#define NVOS_IS_WINDOWS_X86   0
 
#define NVOS_IS_LINUX_KERNEL   0
 
#define NV_MIN_F32   (1.1754944e-38f)
 Min/Max values for NvF32. More...
 
#define NV_MAX_F32   (3.4028234e+38f)
 
#define NV_ALIGN_POINTER(t, f)   t f
 Declares a 64-bit aligned pointer. More...
 
#define NV_DEBUG_CODE(x)
 Function attributes are lumped in here too. More...
 
#define NV_ARRAY_SIZE(x)   (sizeof(x) / sizeof((x)[0]))
 Macro for determining the size of an array. More...
 
#define NV_MIN(a, b)   (((a) < (b)) ? (a) : (b))
 Macro for taking min or max of a pair of numbers. More...
 
#define NV_MAX(a, b)   (((a) > (b)) ? (a) : (b))
 
#define NV_OFFSETOF(type, member)   ((NvUPtr)(&(((type *)0)->member)))
 Macro for determining the offset of "member" in "type". More...
 
#define NV_SIZEOF(s, e)   (sizeof(((s*)0)->e))
 Macro for determining the size of an element e in struct s. More...
 
#define NV_LOWEST_BIT_ONLY(v)   ((NvU32)(v) & (NvU32)-(NvS32)(v))
 Get just the lowest bit of the 32 bit number. More...
 
#define NV_IS_POWER_OF_2(v)   (NV_LOWEST_BIT_ONLY(v) == (NvU32)(v))
 True if unsigned int v is a power of 2. More...
 
#define NV_WAIT_INFINITE   0xFFFFFFFF
 By convention, we use this value to represent an infinite wait interval in APIs that expect a timeout argument. More...
 
#define NV_ANALYSIS_ASSUME(x)
 Macro to help with MSVC Code Analysis false positives. More...
 
#define NvDiv64(dividend, divisor)   NvDiv64Inline(dividend, divisor)
 

Typedefs

typedef NvU64 NvPhysAddr64
 A physical address type sized such that it matches the addressing support of the hardware modules with which HW drivers typically interfaces. More...
 
typedef NvU32 NvRmPhysAddr
 This is deprecated and shouldn't be used. More...
 
typedef union NvData32Rec NvData32
 Union that can be used to view a 32-bit word as your choice of a 32-bit unsigned integer, a 32-bit signed integer, or an IEEE single-precision float. More...
 
typedef union NvData64Rec NvData64
 Generic data representation for both 32 and 64 bits data. More...
 
typedef struct NvPointRec NvPoint
 This structure is used to determine a location on a 2-dimensional object, where the coordinate (0,0) is located at the top-left of the object. More...
 
typedef struct NvPointF32Rec NvPointF32
 
typedef struct NvRectRec NvRect
 This structure is used to define a 2-dimensional rectangle where the rectangle is bottom right exclusive (that is, the right most column, and the bottom row of the rectangle is not included). More...
 
typedef struct NvRectF32Rec NvRectF32
 This structure is used to define a 2-dimensional rectangle relative to some containing rectangle. More...
 
typedef struct NvSizeRec NvSize
 This structure is used to define a 2-dimensional surface where the surface is determined by it's height and width in pixels. More...
 

Functions

static NV_FORCE_INLINE NvU64 NvDiv64Inline (NvU64 dividend, NvU32 divisor)
 Performs the 64-bit division and returns the quotient. More...
