3973 5569 d 5 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()		  
3940 5575 d 23 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3908 5579 d 21 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
2071 6340 d 20 h jermar /trunk/ (c) versus (C)  
1888 6465 d 23 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6530 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6537 d 23 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6559 d 2 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1396 6581 d 20 h palkovsky /kernel/trunk/ Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().		  
793 6686 d 1 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
760 6690 d 3 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.		  
689 6715 d 0 h bondari /kernel/trunk/ Frame alloc test #1  
684 6715 d 1 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.		  
548 6747 d 20 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6749 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6749 d 21 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 6749 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6762 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
341 6833 d 2 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
319 6838 d 6 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.
