Yes, I don't want to spoil your fun. I even do such things myself
sometimes. See the port to Native NT (which also allows you basically
to write Windows NT drivers). But the developers on a Linux kernel
list might not be that open minded ^^
I have hopes that ReactOS might be usable for some embedded stuff, and
it is good to know if I need any custom drivers that something exists in
FPC. :)
It's not fully implemented currently. The last big update from me was to
get the RTL nearly completly running for user mode applications. I
haven't tested it inside kernel mode yet. But even if it works I
wouldn't recommend to use the functions provided by the RTL inside a
device driver, because you have to less control over what happens inside
those functions (especially regarding paged vs. non-paged memory).
The state of the kernel mode part of Native NT is currently this:
* only legacy type device drivers tested (none of the more current
driver frameworks)
* no usage of the kernel's exception handling (also applies to user
mode); currently you'd need to do this manually in assembler
* no thread related functions
* only x86 currently
It should be not a big problem to enable x86_64, but currently I don't
have a machine to test this (when I upgrade my "server" I hope to be
able to run x86_64 Windows in a VM).
I also plan to add ARM support once ReactOS' ARM port can boot to user
mode (I'd need to test this...)
You might want to keep an eye on this wiki page:
