1268 6673 d 22 h decky /kernel/trunk/arch/ppc32/ minor changes  
1267 6673 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32: proper exception handling from user-space
code cleanup
 
1265 6674 d 0 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 6682 d 0 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().
 
1222 6682 d 14 h decky /kernel/trunk/arch/ init tasks must be registered before main_bsp()  
1220 6682 d 15 h decky /kernel/trunk/arch/ppc32/ ppc32: initial userspace support  
1215 6682 d 17 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1185 6691 d 22 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6691 d 23 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 6693 d 4 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.
 
1163 6695 d 21 h decky /kernel/trunk/arch/ fix types  
1145 6702 d 22 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1132 6711 d 18 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1107 6713 d 15 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1104 6713 d 20 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 6719 d 3 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1067 6719 d 11 h decky /kernel/trunk/arch/ppc32/include/boot/ respect two more reserved frames  
1057 6719 d 18 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6720 d 18 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
1007 6721 d 1 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now
 
1004 6721 d 12 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6721 d 13 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6721 d 13 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
990 6721 d 18 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6721 d 20 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6721 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support  
977 6721 d 23 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
972 6722 d 2 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization
 
970 6722 d 2 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
967 6722 d 2 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
957 6722 d 17 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
951 6722 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32 boots again (temporarily)  
940 6723 d 18 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
938 6723 d 19 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
934 6723 d 20 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)
 
910 6731 d 0 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
867 6741 d 22 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 6743 d 13 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
845 6747 d 1 h decky /kernel/trunk/ fix stupid bug in ppc32 context_save_arch
save only non-volatile registers in context
 
843 6747 d 17 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.
