548 6733 d 3 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6735 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6735 d 3 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 6735 d 3 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6747 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6748 d 1 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.		  
430 6768 d 1 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
391 6796 d 1 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.		  
251 6827 d 22 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.		  
226 6829 d 8 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
195 6831 d 3 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		  
158 6850 d 8 h decky /SPARTAN/trunk/src/mm/ remove forgotten comment  
157 6850 d 8 h decky /SPARTAN/trunk/ remove cyclic including, change linker script path  
125 6877 d 1 h jermar /SPARTAN/trunk/ Huge indentation fix.  
120 6891 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 6912 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.		  
23 6964 d 6 h jermar /SPARTAN/trunk/ Fix wrong order of *_init() function calls.  
1 7024 d 5 h jermar /SPARTAN/ Initial import
