990 6712 d 22 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6713 d 0 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6713 d 2 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6713 d 3 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6713 d 5 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6713 d 6 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6713 d 6 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6713 d 21 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6714 d 1 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6714 d 22 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6714 d 22 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
934 6714 d 23 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
910 6722 d 3 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6733 d 2 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
860 6734 d 17 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
845 6738 d 5 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
843 6738 d 20 h palkovsky /kernel/trunk/ Made powerpc to get on PearPC to the version print when compiled with -O1:
- create proper memory zones
- switch to real mode on boot
TODO
- kernel relocation during boot
- autodetection of framebuffer settings (PCI?) - now includes hardcoded
settings for PearPc.		  
833 6742 d 16 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6746 d 17 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
815 6747 d 4 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
765 6752 d 19 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6753 d 2 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6753 d 4 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 6754 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.		  
727 6766 d 18 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6773 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().		  
674 6782 d 5 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6796 d 22 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6797 d 16 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 6802 d 1 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 6807 d 1 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.		  
581 6807 d 5 h palkovsky /kernel/trunk/ Small debug changes.  
569 6808 d 18 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
534 6812 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6812 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6825 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
493 6825 d 18 h jermar /SPARTAN/trunk/ Move genarch/{src|include}/firmware/ofw to genarch/{src|include}/ofw.  
475 6837 d 3 h jermar /SPARTAN/trunk/ Define atomic_t type.  
421 6852 d 17 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 6860 d 7 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.
