1107 6714 d 16 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6714 d 21 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 6720 d 4 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1067 6720 d 12 h decky /kernel/trunk/arch/ppc32/include/boot/ respect two more reserved frames  
1057 6720 d 19 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6721 d 19 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1007 6722 d 2 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1004 6722 d 13 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6722 d 14 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6722 d 14 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
990 6722 d 19 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6722 d 21 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6722 d 23 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6723 d 0 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6723 d 3 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6723 d 3 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6723 d 3 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6723 d 18 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6723 d 23 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6724 d 19 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6724 d 20 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
934 6724 d 21 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
910 6732 d 1 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6742 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 6744 d 14 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
845 6748 d 2 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
843 6748 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 6752 d 13 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6756 d 14 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
815 6757 d 1 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
765 6762 d 17 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6762 d 23 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6763 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 6764 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 6776 d 16 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6783 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 6792 d 2 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6806 d 20 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6807 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 6811 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.
