938 6821 d 2 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
919 6824 d 8 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 6832 d 9 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 6854 d 0 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.		  
756 6860 d 20 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 6862 d 4 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
740 6868 d 6 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 6872 d 22 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
684 6884 d 5 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 6888 d 9 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
583 6913 d 5 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.		  
539 6918 d 1 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.		  
534 6919 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6919 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
519 6925 d 23 h vana /kernel/trunk/arch/ia64/ Keyboard support for ski (ia64 emulator)  
501 6931 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6938 d 22 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6939 d 1 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.		  
470 6944 d 19 h jermar /SPARTAN/trunk/ ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.

ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement.		  
457 6945 d 9 h decky /SPARTAN/trunk/ new build system almost finished
