Copy Link

Mainly debug stuff: have a working stack trace, and panic.
To get symbol names & offsets, we link the kernel once, then export a symbol table (text file), then make an assembly symbol table out of it with some python. Then assemble and link it to the kernel.
So it's effectively linked 2 times.
Also set up the kernel stack because until now we were using the one provided by Limine.
However still get:

  1. Page Fault when using the keyboard (sending kbd interrupts) when the PS/2 driver hasn't initialized yet
  2. GP Fault when processes are accessing the framebuffer; maybe we should implement a spinlock for these sensible regions (serial, kbd, framebuffer, etc.) as there are only ONE way to access them, and there might be MULTIPLE processes running.
