566	6727 d 12 h	palkovsky	/kernel/trunk/	Fixed bug in Intel32/AMD64 boot, that could cause page fault on boot. Fixes of configuration program.
548	6728 d 16 h	jermar	/kernel/trunk/	Cleanup and fixes.
540	6729 d 13 h	jermar	/kernel/trunk/arch/	Map all available frames of memory on ia32 and amd64 (ticket #10).
534	6730 d 16 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
533	6730 d 16 h	bondari	/SPARTAN/trunk/	Buddy allocator for physical memory complete implementation. Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed. NOTE: Other architectures could be broken (but should not be)
532	6730 d 17 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6742 d 21 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
492	6743 d 14 h	jermar	/SPARTAN/trunk/	Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find(). New names should make it more apparent that these two belong together.
368	6804 d 22 h	jermar	/SPARTAN/trunk/	Physical memory management work. New frame allocator. Some architectures need to have bigger heap.
323	6817 d 0 h	jermar	/SPARTAN/trunk/	Add comments for new floating point modifiers to print.c. Remove left-over comments from AMD64 and IA-32 page.c. Coding style clean up.
298	6821 d 0 h	decky	/SPARTAN/trunk/	remove lower 2 GB identity mapping (IA-32)
235	6824 d 19 h	decky	/SPARTAN/trunk/	load the kernel above 1 MB on IA-32
205	6826 d 2 h	jermar	/SPARTAN/trunk/	Get rid of memcopy(). All we now have is memcpy() and _memcpy(). memcpy() is defined to be builtin. Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().
195	6826 d 16 h	vana	/SPARTAN/trunk/	1) memcopy and _memcopy functions rewriten to ANSI C norm. 2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions 3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
167	6837 d 23 h	jermar	/SPARTAN/trunk/	Switch over to per vm_t page tables. (breaks ia32 userspace) Define dummy memcopy() for amd64 and ppc to satisfy compiler. Get rid of problematic #include <arch/mm/page.h> in mm/page.h. Indentation fixes and small changes here and there.
125	6872 d 14 h	jermar	/SPARTAN/trunk/	Huge indentation fix.
120	6887 d 13 h	jermar	/SPARTAN/trunk/	Generic 4-level page tables interface & implementation (review & test). Implement more architecture dependant macros on IA-32. Provide fake implementation on IA-64 and MIPS. Convert map_page_to_frame() to use the new interface. Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c.
116	6907 d 20 h	jermar	/SPARTAN/trunk/	Add map_structure() to automate mapping of memory structures that can span multiple pages and/or cross page boundaries. Change ACPI map_sdt() to use map_structure(). Small changes in MPS code. The extra frame allocation for accessing frame 0 is unnecessary as it is possible to access frame 0 from kernel address space. Zero TSS descriptor in the newly prepared GDT.
115	6908 d 12 h	jermar	/SPARTAN/trunk/	Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file. Gain both better speed and size.
113	6911 d 11 h	jermar	/SPARTAN/trunk/	SMP recovery patch #2 (SMP is no longer broken !!!). Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization. Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address. Make references to page directory and page tables use kernel addresses instead of physical addresses. Massive frame allocation code cleanup. Basically revert to what we had had before implementation of userspace. Usual cosmetics.
