__ptrd, __ptri

  • Artikel

Microsoft Specific

Emit the IPF Purge Translation Register (ptr) instruction.

void __ptrd( 
   __int64 Address, 
      __int64 Range 
);
void __ptri( 
   __int64 Address, 
      __int64 Range 
);

Parameters

  • [in] Address
    Loaded into the first general register supplied to the instruction. Bits 0 to 60 specify the virtual address to purge. Bits 61 to 63 specify the region identifier.

  • [in] Range
    Loaded into the second general register supplied to the instruction. Bits 2 to 7 represent the page size; other bits are ignored.

Remarks

The instruction has two forms: ptr.d (data) and ptr.i (instruction). The intrinsics emit the similarly named form of the instruction. Unlike __ptcg and __ptcga, the operation is local to the processor.

For more information, see the Intel IPF documentation. These routines are only available as intrinsics.
