1184 6692 d 15 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 20 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1165 6696 d 12 h decky /kernel/trunk/arch/ set ELF format explicitly  
1163 6696 d 13 h decky /kernel/trunk/arch/ fix types

1160 6696 d 13 h decky /kernel/trunk/ start ppc64 port
the code is currently a wild mixture of 32/64b code, will be fixed		  
1151 6700 d 18 h decky /kernel/trunk/arch/ppc32/src/mm/ ppc32: mark four first frames as unavailable  
1145 6703 d 14 h decky /kernel/trunk/arch/ppc32/ align ppc32 framebuffer on 128K boundary  
1135 6711 d 6 h decky /kernel/trunk/ framebuffer code cleanup, support for non-standard scanline sizes
ppc32: get framebuffer parameters from boot loader		  
1132 6712 d 10 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
1124 6712 d 18 h jermar /kernel/trunk/arch/ Small changes.
Make sparc64 and ppc32 compile again.		  
1107 6714 d 7 h jermar /kernel/trunk/ Small atomic #include and typedef changes.  
1106 6714 d 7 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1104 6714 d 12 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 19 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1067 6720 d 3 h decky /kernel/trunk/arch/ppc32/include/boot/ respect two more reserved frames  
1057 6720 d 10 h decky /kernel/trunk/arch/ppc32/ update kernel/loader API  
1024 6721 d 10 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1007 6721 d 17 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1004 6722 d 4 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
1001 6722 d 5 h decky /kernel/trunk/arch/ppc32/include/ fix semantics  
1000 6722 d 5 h decky /kernel/trunk/arch/ppc32/include/ add atomic_pre/post_inc/dec  
990 6722 d 10 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
987 6722 d 12 h decky /kernel/trunk/arch/ppc32/ ppc32: initial exception support  
982 6722 d 14 h decky /kernel/trunk/arch/ppc32/ ppc32: initial I/O support

940 6724 d 10 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6724 d 11 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
934 6724 d 12 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code

897 6737 d 5 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.

867 6742 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.
