1132 6683 d 18 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1107 6685 d 15 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6685 d 20 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1070 6691 d 3 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1067 6691 d 11 h decky /kernel/trunk/arch/ppc32/include/boot/ respect two more reserved frames  
1057 6691 d 18 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6692 d 18 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1007 6693 d 1 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1004 6693 d 12 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6693 d 13 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6693 d 13 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
990 6693 d 18 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6693 d 20 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6693 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6693 d 23 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6694 d 1 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6694 d 2 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6694 d 2 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6694 d 17 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6694 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6695 d 18 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6695 d 18 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
934 6695 d 20 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
910 6702 d 23 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6713 d 22 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 6715 d 13 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
845 6719 d 1 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
843 6719 d 16 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 6723 d 12 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6727 d 13 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
815 6728 d 0 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
765 6733 d 16 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6733 d 22 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6734 d 0 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 6735 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.		  
727 6747 d 15 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6754 d 0 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 6763 d 1 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6777 d 19 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6778 d 12 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)
