1057 6693 d 19 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6694 d 19 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1007 6695 d 2 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1004 6695 d 13 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6695 d 14 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6695 d 14 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
990 6695 d 19 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6695 d 21 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6695 d 23 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6696 d 0 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6696 d 3 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6696 d 3 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6696 d 4 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6696 d 18 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6696 d 23 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6697 d 19 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6697 d 20 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
934 6697 d 21 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
910 6705 d 1 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6715 d 23 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 6717 d 14 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
845 6721 d 3 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
843 6721 d 18 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 6725 d 13 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6729 d 15 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
815 6730 d 1 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
765 6735 d 17 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6735 d 23 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6736 d 1 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 6737 d 14 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 6749 d 16 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6756 d 1 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 6765 d 3 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6779 d 20 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6780 d 14 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 6784 d 22 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 6789 d 22 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.		  
581 6790 d 2 h palkovsky /kernel/trunk/ Small debug changes.  
569 6791 d 16 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
534 6795 d 19 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.
