1070 6677 d 19 h jermar /kernel/trunk/ More checks for address space area conflicts.

1057 6678 d 10 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6679 d 10 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.

990 6680 d 10 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6680 d 13 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6680 d 14 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6680 d 15 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6680 d 18 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization
 
970 6680 d 18 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6680 d 19 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6681 d 9 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6681 d 14 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6682 d 10 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
938 6682 d 11 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
934 6682 d 12 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)
 
910 6689 d 16 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6700 d 14 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 6702 d 5 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
845 6705 d 18 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context
 
843 6706 d 9 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 6710 d 4 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.  
823 6714 d 6 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
815 6714 d 16 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
765 6720 d 8 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6720 d 14 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.
 
760 6720 d 17 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 6722 d 5 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 6734 d 7 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
703 6740 d 16 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 6749 d 18 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6764 d 11 h jermar /kernel/trunk/arch/ Compilation fixes.  
651 6765 d 5 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 6769 d 13 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 6774 d 13 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.
 
581 6774 d 17 h palkovsky /kernel/trunk/ Small debug changes.
