This page describes the current status of the AMD64 port of ReactOS. AMD64 refers to AMD's specifications for a 64-bit extension to the x86 instruction set. It is also known as x86-64 (and variants such as x86_64 and x64).
The ros-amd64-bringup branch was created on r34699 by Timo Kreuzer.
Status
* Everything builds
* A bootcd is created
* setupldr loads, switches the cpu to long mode, initializes hardware/memory/paging and jumps to ntoskrnl
* Basic Mm initialization is done, then the system crashes
* Non paged pool allocations work
* Debugging with WinDbg (break points, single stepping etc) works
* Enabling interrupts makes everything go nots
Completion Status (rough estimates)
completition comment
freeldr 95% only fixes expected
hal 5% only initial work has been done, most missing is support for interrupts
ntoskrnl/ke 50% core functionality is implemented
ntoskrnl/mm 10% only a few functions are implemented, most stuff is missing
rtl 60% exception handling is missing and unwinding is incomplete
crt 60% missing stuff here and there
PSEH 0% unimplemented. Waiting for mingw-w64 support
