1267 6689 d 4 h decky /kernel/trunk/arch/ppc32/ ppc32: proper exception handling from user-space
code cleanup		  
1265 6689 d 6 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1223 6697 d 6 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1222 6697 d 20 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1220 6697 d 21 h decky /kernel/trunk/arch/ppc32/ ppc32: initial userspace support  
1215 6697 d 23 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1185 6707 d 4 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6707 d 5 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.		  
1171 6708 d 10 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1163 6711 d 3 h decky /kernel/trunk/arch/ fix types  
1145 6718 d 4 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1132 6727 d 0 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1107 6728 d 21 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6729 d 2 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 6734 d 9 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1067 6734 d 17 h decky /kernel/trunk/arch/ppc32/include/boot/ respect two more reserved frames  
1057 6735 d 0 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6736 d 0 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1007 6736 d 7 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1004 6736 d 18 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6736 d 19 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6736 d 19 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
990 6737 d 0 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6737 d 2 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6737 d 4 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6737 d 5 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6737 d 8 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6737 d 8 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6737 d 8 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6737 d 23 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6738 d 4 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6739 d 0 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6739 d 1 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
934 6739 d 2 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
910 6746 d 6 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6757 d 4 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 6758 d 19 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
845 6762 d 7 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context		  
843 6762 d 23 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 6766 d 18 h jermar /kernel/trunk/arch/ppc32/include/mm/ Fix ppc32 to at least compile again.
