1145 6633 d 19 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1132 6642 d 15 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1107 6644 d 11 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6644 d 17 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 6650 d 0 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1067 6650 d 8 h decky /kernel/trunk/arch/ppc32/include/boot/ respect two more reserved frames  
1057 6650 d 15 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6651 d 15 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
1007 6651 d 22 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now
 
1004 6652 d 9 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6652 d 10 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6652 d 10 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
990 6652 d 15 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6652 d 17 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6652 d 19 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6652 d 20 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6652 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization
 
970 6652 d 23 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6652 d 23 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6653 d 14 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6653 d 19 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6654 d 15 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
938 6654 d 15 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
934 6654 d 17 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)
 
910 6661 d 20 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6672 d 19 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 6674 d 10 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
845 6677 d 22 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context
 
843 6678 d 13 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 6682 d 9 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6686 d 10 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
815 6686 d 21 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
765 6692 d 13 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6692 d 19 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
 
760 6692 d 21 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 6694 d 10 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 6706 d 12 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
703 6712 d 21 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 6721 d 22 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6736 d 16 h jermar /kernel/trunk/arch/ Compilation fixes.
