765 6688 d 22 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6689 d 4 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6689 d 6 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.		  
756 6690 d 19 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.		  
727 6702 d 21 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6709 d 6 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().		  
674 6718 d 7 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6733 d 1 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6733 d 19 h decky /kernel/trunk/ remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work)		  
625 6738 d 3 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.		  
586 6743 d 3 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.		  
581 6743 d 7 h palkovsky /kernel/trunk/ Small debug changes.  
569 6744 d 20 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
534 6748 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6749 d 0 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6761 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
493 6761 d 21 h jermar /SPARTAN/trunk/ Move genarch/{src|include}/firmware/ofw to genarch/{src|include}/ofw.  
475 6773 d 5 h jermar /SPARTAN/trunk/ Define atomic_t type.  
421 6788 d 19 h jermar /SPARTAN/trunk/ Create genarch directory.
Move ppc32 ofw.[ch] to genarch.
Fix prototype for ofw_call() to return __address instead of int (please review).
Fix copyright notice in sparc64/boot/boot.S.		  
414 6796 d 10 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.
