1059 6654 d 21 h jermar /kernel/trunk/ Clear user address space when creating new page tables.
Fix mapping of l_apic and io_apic on amd64.		  
1053 6655 d 0 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
938 6658 d 23 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
919 6662 d 4 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.		  
901 6670 d 6 h jermar /kernel/trunk/arch/ ia64 work.
Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler.
Add before_thread_runs_arch() that maps kstack, if necessary.
Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.		  
811 6691 d 21 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.		  
756 6698 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.		  
753 6700 d 0 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
740 6706 d 2 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 6710 d 19 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
684 6722 d 2 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.		  
674 6726 d 5 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
583 6751 d 2 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.		  
539 6755 d 22 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.		  
534 6756 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6756 d 22 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
519 6763 d 19 h vana /kernel/trunk/arch/ia64/ Keyboard support for ski (ia64 emulator)  
501 6769 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6776 d 19 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6776 d 21 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
