1277 6639 d 11 h decky /kernel/trunk/arch/ppc32/ ppc32 work:
(hopefully) final exception entry and exit rewrite
don't use FPU instructions in the kernel
syscall support		  
1270 6640 d 6 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6640 d 7 h decky /kernel/trunk/ PHT Refill handler  
1268 6640 d 12 h decky /kernel/trunk/arch/ppc32/ minor changes  
1267 6640 d 12 h decky /kernel/trunk/arch/ppc32/ ppc32: proper exception handling from user-space
code cleanup		  
1265 6640 d 13 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 6648 d 14 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1222 6649 d 3 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1220 6649 d 4 h decky /kernel/trunk/arch/ppc32/ ppc32: initial userspace support  
1215 6649 d 7 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1185 6658 d 12 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6658 d 12 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 6659 d 18 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1163 6662 d 10 h decky /kernel/trunk/arch/ fix types  
1145 6669 d 12 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1132 6678 d 7 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1107 6680 d 4 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6680 d 9 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 6685 d 17 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1067 6686 d 1 h decky /kernel/trunk/arch/ppc32/include/boot/ respect two more reserved frames  
1057 6686 d 8 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6687 d 8 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1007 6687 d 14 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1004 6688 d 2 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6688 d 2 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6688 d 3 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
990 6688 d 8 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6688 d 10 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6688 d 11 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6688 d 13 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6688 d 15 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6688 d 16 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6688 d 16 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6689 d 7 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6689 d 11 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6690 d 8 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6690 d 8 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
934 6690 d 9 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
910 6697 d 13 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6708 d 12 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.
