548	6917 d 2 h	jermar	/kernel/trunk/	Cleanup and fixes.
540	6917 d 23 h	jermar	/kernel/trunk/arch/	Map all available frames of memory on ia32 and amd64 (ticket #10).
534	6919 d 2 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
533	6919 d 2 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	6919 d 3 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6931 d 7 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
492	6932 d 0 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	6993 d 8 h	jermar	/SPARTAN/trunk/	Physical memory management work. New frame allocator. Some architectures need to have bigger heap.
323	7005 d 10 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	7009 d 10 h	decky	/SPARTAN/trunk/	remove lower 2 GB identity mapping (IA-32)
235	7013 d 5 h	decky	/SPARTAN/trunk/	load the kernel above 1 MB on IA-32
205	7014 d 12 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	7015 d 2 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	7026 d 9 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	7061 d 0 h	jermar	/SPARTAN/trunk/	Huge indentation fix.
120	7075 d 23 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	7096 d 6 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	7096 d 22 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	7099 d 21 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.
110	7101 d 7 h	jermar	/SPARTAN/trunk/	SMP recovery patch #1. (SMP still broken) Move ap_boot() to K_TEXT_START_2 section. Change ap_boot() to cope with mapping of kernel address space. Change some addresses in mps.c from kernel to physical. MIPS. Move msim dprinter device to 0xB0000000. This address is from kseg1 (unmapped, uncached) segment.
