Typedef Documentation

◆ PCV_AcpiTable

typedef const volatile AcpiTable* PCV_AcpiTable

◆ PCV_u8

typedef const volatile u8* PCV_u8

Function Documentation

◆ acpi_GetTable()

const AcpiTable* acpi_GetTable ( const char *  signature)
Parameters
signaturee.g. "RSDT"
Returns
pointer to internal storage (valid until acpi_Shutdown())

note: the first call may be slow, e.g. if a kernel-mode driver is loaded. subsequent requests will be faster since tables are cached.

◆ acpi_Shutdown()

void acpi_Shutdown ( )

invalidates all pointers returned by acpi_GetTable.

◆ AllocateAndCopyTables()

static void AllocateAndCopyTables ( const AcpiTable **&  tables,
size_t &  numTables 
)
static

◆ AllocateTable()

static AcpiTable* AllocateTable ( size_t  size)
static

◆ ComputeChecksum()

static u8 ComputeChecksum ( PCV_u8  buf,
size_t  numBytes 
)

◆ DeallocateTable()

template<typename T >
static void DeallocateTable ( const T table)

◆ ValidateTable()

const char *  signature = 0 
)
