Jonas 'Sortie' Termansen	b0df5186e6	Fixed two very nasty bugs in the x86 memory management code. ... 1) The PML2 was not initialized to zeroes, thus leaving some bits behind that caused the fork code to go crazy, forking the unforkable, and mapping addresses that never, ever, should have been mapped, leaving behind a trail of page faults and general protection faults on some computers, while other computers worked because the uninitalized memory just wasn't uninitialized enough. Yep, this was a schrödinbug! 2) Fixed a time bomb. The kernel heap was accidentally put such that whenever a few megabytes were allocated, it would begin overwriting the physical page stack causing unthinkable events to unfold and would probably be even more obscure to debug than 1). Oh, and some string errors fixed and removed RunApplication from kernel.cpp, funny thing that even linked in the first place. Guess, the optimizer actually did work for once. :)	2011-10-20 03:52:08 +02:00

Jonas 'Sortie' Termansen	cc61176e5b	Restored support for JSSortix using very ugly hacks. :(	2011-09-08 11:10:41 +02:00

Jonas 'Sortie' Termansen	b80195dc19	Implemented the new physical page allocator API.	2011-08-22 21:12:55 +02:00
Jonas 'Sortie' Termansen	9995354f95	Moved CPU code shared by x86 and x64 into x86-family.	2011-08-12 17:33:18 +02:00
Jonas 'Sortie' Termansen	64d191a882	x86 now has a driver for rebooting.	2011-08-12 15:13:18 +02:00
Jonas 'Sortie' Termansen	66c058fba1	Refactored virtual memory management, making it less buggy. ... uintptr_t is now replaced with addr_t when referring to physical memory addresses in Sortix. Many bugs in the previous memory management code have been fixed. The new interface is less flexible - but should prove more solid as the nasty internals have been hidden away. The current interface design should also make the code more 64-bit ready/friendly. And so on.	2011-08-07 00:18:41 +02:00
