Jonas 'Sortie' Termansen	4841d83ff8	Added calloc(3).	2011-12-24 04:05:38 +01:00
Jonas 'Sortie' Termansen	0515111314	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.	2011-12-22 14:13:18 +01:00
Jonas 'Sortie' Termansen	acf1eebc98	Added user-space memory allocation.	2011-12-16 13:24:49 +01:00
Jonas 'Sortie' Termansen	5bc05c4e0e	Moved around comments in heap.cpp.	2011-12-04 20:59:42 +01:00
Jonas 'Sortie' Termansen	c0c20860ed	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
Jonas 'Sortie' Termansen	6781308360	Rewrote the memory allocation functions. ... free(3) can now unify unused neighbor blocks, reducing mem usage.	2011-11-27 22:53:05 +01:00
