I saw your post about your rust kernel. Did you ever figure out what was
wrong?

Also have you tried using QEMU?

First I would verify that your serial code is actually running. You could
triple fault the x86_64 to detect if it reaches a certain point.

Also setup of serial port on QEMU for x86_64 is very easy. All you do is
send the data and check the buffer. I have some great example Rust code.
Now real hardware is different because it can be touchy if you dont
properly intialize it.

Your code looks good okay so im wondering if it can be verified as running
- like I said QEMU can help you diagnose simple problems thsy will be
present in real hardware. Also be aware of QEMU monitor mode which lets you
dump the CPU registers during runtime so you can see exactly what the CPU
is executing.

Let me know because I can likely help you a bunch.

Well, actually I notice your code does not check that the UART buffer is
full which I think it is supposed to check, however from your mail it seems
like it is not outputting anything?

Thanks Kevin,

I need all the help - thanks for offering.
Regarding the &str issue - it went away after I replaced the linker script
with the one from osdev.org.

I've run into a new issue (link issue - I've sent an email about it) with
the latest nightly - something may have broken in the latest nightly

Regards,
Kashyap
