2071 6323 d 16 h jermar /trunk/ (c) versus (C)  
2064 6337 d 15 h vana /trunk/ SIMICS added as a simulator kernel runs on  
1802 6508 d 12 h decky /trunk/ cleanup and unify the build system  
1787 6513 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1495 6553 d 12 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.
 
1210 6595 d 0 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1191 6602 d 4 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1106 6624 d 14 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1059 6630 d 17 h jermar /kernel/trunk/ Clear user address space when creating new page tables.
Fix mapping of l_apic and io_apic on amd64.
 
1053 6630 d 20 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
938 6634 d 18 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
919 6638 d 0 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 6646 d 2 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 6667 d 16 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.
 
756 6674 d 13 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 6675 d 20 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.
 
740 6681 d 22 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 6686 d 14 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
684 6697 d 22 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 6702 d 1 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
583 6726 d 22 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.
 
539 6731 d 18 h jermar /kernel/trunk/ Buddy allocator cleanup and fixes.
- Add some comments.
- Update zone information on frames allocation/deallocation.
 
534 6732 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6732 d 17 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
519 6739 d 15 h vana /kernel/trunk/arch/ia64/ Keyboard support for ski (ia64 emulator)  
501 6744 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6752 d 14 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6752 d 17 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 6758 d 11 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 6759 d 1 h decky /SPARTAN/trunk/ new build system almost finished  
455 6759 d 13 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
 
435 6761 d 16 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.
 
431 6764 d 1 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.
 
430 6765 d 15 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
376 6802 d 20 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!
 
368 6806 d 23 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
326 6818 d 12 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
 
293 6823 d 13 h palkovsky /SPARTAN/trunk/ Symbol table now contains static functions too.
NOTE: gcc heavily inlines, be aware of optimizations.

Removed excesive item from boot page tables.
 
289 6823 d 17 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.
 
272 6824 d 19 h vana /SPARTAN/trunk/arch/ia64/ Symtab support for ia64
