1277 6659 d 0 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 6659 d 19 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6659 d 20 h decky /kernel/trunk/ PHT Refill handler  
1268 6660 d 1 h decky /kernel/trunk/arch/ppc32/ minor changes  
1267 6660 d 1 h decky /kernel/trunk/arch/ppc32/ ppc32: proper exception handling from user-space
code cleanup		  
1265 6660 d 3 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 6668 d 3 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1222 6668 d 16 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1220 6668 d 17 h decky /kernel/trunk/arch/ppc32/ ppc32: initial userspace support  
1215 6668 d 20 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1185 6678 d 1 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6678 d 2 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 6679 d 7 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1163 6682 d 0 h decky /kernel/trunk/arch/ fix types  
1145 6689 d 1 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1132 6697 d 21 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1107 6699 d 18 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6699 d 23 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 6705 d 6 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1067 6705 d 14 h decky /kernel/trunk/arch/ppc32/include/boot/ respect two more reserved frames  
1057 6705 d 21 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6706 d 21 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1007 6707 d 4 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1004 6707 d 15 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6707 d 16 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6707 d 16 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
990 6707 d 21 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6707 d 23 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6708 d 1 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6708 d 2 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6708 d 4 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6708 d 5 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6708 d 5 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6708 d 20 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6709 d 1 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6709 d 21 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6709 d 22 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
934 6709 d 23 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
910 6717 d 3 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6728 d 1 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.
