1007	6776 d 14 h	decky	/kernel/trunk/	ppc32: preemptive scheduling works now FPU context saving disabled for now
1004	6777 d 2 h	decky	/kernel/trunk/	ppc32: basic exception and interrupt handling
1001	6777 d 2 h	decky	/kernel/trunk/arch/ppc32/include/	fix semantics
1000	6777 d 3 h	decky	/kernel/trunk/arch/ppc32/include/	add atomic_pre/post_inc/dec
993	6777 d 7 h	jermar	/kernel/trunk/arch/ia64/	Fix bug in switch to userspace on ia64: ensure start in bank 1. Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled. Optimize context switching by discarding packed attribute of context structures.
990	6777 d 8 h	decky	/kernel/trunk/	ppc32: initial stack, memory barriers, atomic operations, stack offset fix
987	6777 d 10 h	decky	/kernel/trunk/arch/ppc32/	ppc32: initial exception support
984	6777 d 11 h	palkovsky	/kernel/trunk/arch/	Fixed invlpg for ia32 & amd64.
983	6777 d 11 h	palkovsky	/kernel/trunk/	Fixed shrinking of as area.
982	6777 d 12 h	decky	/kernel/trunk/arch/ppc32/	ppc32: initial I/O support
980	6777 d 12 h	palkovsky	/kernel/trunk/	Small speed update of ipc. Fixed some bugs regarding pages in mremap.
979	6777 d 13 h	vana	/kernel/trunk/arch/ia64/	Itanium FPU context save/restore
977	6777 d 13 h	jermar	/kernel/trunk/	Add sys_mremap() syscall.
972	6777 d 15 h	decky	/kernel/trunk/arch/ppc32/	ppc32: move kernel one frame up frame zones initialization
970	6777 d 16 h	decky	/kernel/trunk/arch/ppc32/	ppc32: get memory map from loader
967	6777 d 16 h	palkovsky	/kernel/trunk/	Allowed userspace to include page.h.
962	6778 d 5 h	jermar	/kernel/trunk/arch/ia64/	ia64 work. Support for __SYSCALL4. Fix user stack initial address.
959	6778 d 6 h	palkovsky	/kernel/trunk/	New synchronous ipc. Widened syscall to support up to 5 parameters.
958	6778 d 7 h	jermar	/kernel/trunk/	Nicer ia32 interrupt handlers and structures holding interrupted context data. Unify the name holding interrupted context data on all architectures to be istate.
957	6778 d 7 h	decky	/kernel/trunk/arch/	run ppc32 kernel above 2 GB
955	6778 d 7 h	palkovsky	/kernel/trunk/	Added kernel IPC functionality.
952	6778 d 11 h	jermar	/kernel/trunk/	Support for loading segments containing .bss section.
951	6778 d 11 h	decky	/kernel/trunk/arch/ppc32/	ppc32 boots again (temporarily)
947	6778 d 16 h	vana	/kernel/trunk/	Better purge page selection.
945	6779 d 5 h	vana	/kernel/trunk/arch/ia64/
944	6779 d 6 h	vana	/kernel/trunk/	Itanium tlb_invalidate_pages
941	6779 d 8 h	palkovsky	/kernel/trunk/	Fixed mips elf loading.
940	6779 d 8 h	jermar	/kernel/trunk/	Get rid of unneeded macros. Their functionality has been replaced by the ELF loader.
938	6779 d 8 h	jermar	/kernel/trunk/	Basic support for loading ELF object files. ia64, amd64, ia32 working. mips32 requires some attention.
935	6779 d 9 h	vana	/kernel/trunk/	Two frame stack (standard stack + RSE) on Itanium
934	6779 d 9 h	decky	/kernel/trunk/arch/ppc32/	remove all OpenFirmware bindings from ppc32 kernel code kernel now runs in real mode (ppc32)
928	6779 d 14 h	vana	/kernel/trunk/	Itanium tlb_invalidate_all
925	6779 d 17 h	palkovsky	/kernel/trunk/arch/ia32/src/mm/	Fix e820list on ia32.
924	6779 d 18 h	palkovsky	/kernel/trunk/arch/mips32/	Macro redefinition for mips fpu.
923	6780 d 2 h	vana	/kernel/trunk/arch/ia64/src/	paging_start counting fix on ia64
921	6782 d 9 h	jermar	/kernel/trunk/arch/ia64/	ia64 work. Userspace is now working. There is an unrelated show stopper, however.
919	6782 d 14 h	jermar	/kernel/trunk/	ia64 work. Changes to make userspace work (kernel part). Use ski.conf from contrib directory to run Ski. There is actually no appropriate syscall handler yet.
916	6784 d 16 h	jermar	/kernel/trunk/arch/ia64/src/	ia64 work. Support switch from userspace register stack in heavyweight handler.
915	6784 d 17 h	jermar	/kernel/trunk/arch/ia64/	ia64 work. - Another item had to be allocated on stack to remember new value written to ar.bspstore. Fix heavyweight interruption handler to calculate RSC.loadrs from the new value of ar.bspstore instead from the old one. Uncomment instructions switching ar.bspstore. - Configure kernel with 512M of memory.
912	6786 d 6 h	jermar	/kernel/trunk/	ia64 work. ivt.S: Detect userspace stack in heavyweight handler and switch to kernel stack. Remember the old stack pointer. As for register stack, kernel stack is assumed still. Fix alignment issues that showed when STACK_ITEMS was odd. Fix ld8 instruction that did subtraction of 8 instead of addition of 8. scheduler.c: Change before_thread_runs_arch() to calculate address of top of the stack for the interrupt handler.
