Title: PMIO(port-mapped I/O) x64
Post by: shaynox on January 16, 2015, 04:26:33 PM
Hello,

3-Volume 2B Instruction Set Reference, N-Z (chap OUT)

Is it normal in these intel doc, it's wrote, 64-bit mode valid ?

Like i learned, it's impossible to do this in x64 OS windows or own OS, so who say the truth ?

And i think of driver (dll) using in windows (gdi32.dll, ..), they use PMIO or MMIO for dialog with hardware (video card).
