Now counting memory usage in a more solid manner.

Added a global variable at the end of the kernel to detect its size.
...
This lets the kernel use any memory not directly used by it or the
init ramdisk. Although, now we test whether the kernel fits into
the identitymapped area. It can't really grow down there, unless it
wants to collide with user-space. Instead, modules and the like
(when they are invented), should be put in the upper memory. Or in
their own user-space process, yay, microkernel!

The initial ramdisk is now mapped onto a special location.
...
This fixes issues where it did not fit into the first few MiB,
or that GRUB loaded it someplace weird.
The kernel heap is now also protected against growing into the
ramdisk and the kernel stack.

usleep'ing for 0 usecs simply causes a context-switch.

Changed the build system for 64-bit quite a bit.
...

Added a very simple checksum field to the init ramdisk.
...
This uncovers a bug where the bootloader may corrupt the initrd on x64.
This is probably related to our kernel64 hack..

Lots of improvements to 64-bit Sortix.
...
Fixed 64-bit-ness bug in BSR() and BSF().
Added 64-bit system call stubs in libmaxsi.
Added a Elf64 program loader.
Fixed uninitialized memory bug in the scheduler.
x64/boot.s now takes care of user-space memory permissions.
Fixed bug in x64/syscall.s
That's right. The system now boots in 64-bit mode.
It is horribly unstable, though.
2011-12-01 10:45:44 +01:00

Added support for 64-bit interrupts.

-1 is no longer an allowed system call.
...
This treats a nasty bug where forking and exiting before the child
causes the kernel to panic, because the syscall -1 is run, which
just contains a trash value that happened to be 0.
The cause is still unknown. Might be the scheduler.
This won't help me sleep at night.
