2089 6495 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6505 d 21 h jermar /trunk/ (c) versus (C)  
1891 6626 d 19 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6627 d 6 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.		  
1889 6627 d 21 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support		  
1888 6631 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1787 6695 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6724 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1511 6735 d 2 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1070 6812 d 7 h jermar /kernel/trunk/ More checks for address space area conflicts.  
940 6816 d 22 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
919 6820 d 5 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.		  
903 6826 d 23 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Add code needed for running multiple address spaces and location of kernel stack
after switch from userspace.		  
756 6856 d 17 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.		  
703 6875 d 4 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().		  
534 6914 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6914 d 22 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6927 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
391 6975 d 19 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.		  
105 7099 d 17 h jermar /SPARTAN/trunk/ Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.

Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.

Cosmetic changes here and there.
