987	6651 d 16 h	decky	/kernel/trunk/arch/ppc32/	ppc32: initial exception support
982	6651 d 18 h	decky	/kernel/trunk/arch/ppc32/	ppc32: initial I/O support
977	6651 d 19 h	jermar	/kernel/trunk/	Add sys_mremap() syscall.
972	6651 d 21 h	decky	/kernel/trunk/arch/ppc32/	ppc32: move kernel one frame up frame zones initialization
970	6651 d 22 h	decky	/kernel/trunk/arch/ppc32/	ppc32: get memory map from loader
967	6651 d 22 h	palkovsky	/kernel/trunk/	Allowed userspace to include page.h.
957	6652 d 13 h	decky	/kernel/trunk/arch/	run ppc32 kernel above 2 GB
951	6652 d 18 h	decky	/kernel/trunk/arch/ppc32/	ppc32 boots again (temporarily)
940	6653 d 14 h	jermar	/kernel/trunk/	Get rid of unneeded macros. Their functionality has been replaced by the ELF loader.
938	6653 d 15 h	jermar	/kernel/trunk/	Basic support for loading ELF object files. ia64, amd64, ia32 working. mips32 requires some attention.
934	6653 d 16 h	decky	/kernel/trunk/arch/ppc32/	remove all OpenFirmware bindings from ppc32 kernel code kernel now runs in real mode (ppc32)
910	6660 d 20 h	bondari	/kernel/trunk/	ELF framework for all archs. SPARC V9 not tested to compile.
867	6671 d 18 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	6673 d 9 h	decky	/kernel/trunk/	indentation changes ppc32 fpu context save/restore ppc32 CPU version ppc32 memcpy
845	6676 d 21 h	decky	/kernel/trunk/	fix stupid bug in ppc32 context_save_arch save only non-volatile registers in context
843	6677 d 13 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.
833	6681 d 8 h	jermar	/kernel/trunk/arch/ppc32/include/mm/	Fix ppc32 to at least compile again.
823	6685 d 9 h	jermar	/kernel/trunk/	Reimplement ASID stealing logic. This time, hopefully, with correct synchronization.
815	6685 d 20 h	jermar	/kernel/trunk/	Fix sparc64 and ia64 to work with the changed frame allocator. Fix ppc32 to at least compile.
765	6691 d 12 h	jermar	/kernel/trunk/	Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
763	6691 d 18 h	jermar	/kernel/trunk/	Modify frame.h to use shifting instead of multiplication and division. Define FRAME_WIDTH for all architectures.
760	6691 d 20 h	jermar	/kernel/trunk/	mips32 is not supposed to allocate page table. This is done by the generic code now. Remove PTL0 pointer as it is not needed. Remove GET_PTL0_ADDRESS from kernel. Update sparc64 comments in barrier.h.
756	6693 d 9 h	jermar	/kernel/trunk/	Memory management work. Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find(). Page table address is now extracted from the first (i.e. 'as') argument. Add a lot of infrastructure to make the above possible. sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
727	6705 d 11 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
703	6711 d 20 h	jermar	/kernel/trunk/	Memory management work. - vm.* -> as.* (as like address space is, imho, more fitting) - Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid(). - Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault(). - Add high-level page fault handler as_page_fault(). - Add as_area_load_mapping().
674	6720 d 21 h	cejka	/kernel/trunk/	Support for printing float numbers in kernel removed.
655	6735 d 15 h	jermar	/kernel/trunk/arch/	Compilation fixes.
651	6736 d 8 h	decky	/kernel/trunk/	remove arch/$ARCH/boot where not needed, change global Makefile accordingly remove early_mapping() (breaks ppc32 for now) change early heap initialization (required for init to work)
625	6740 d 17 h	palkovsky	/kernel/trunk/	We are now almost -Wall clean. - redefined atomic_t - deleted many, many unused variables - some minor code cleanups found using compiler warning.
586	6745 d 17 h	jermar	/kernel/trunk/	Fix ppc32 and sparc64 to compile again. Fix sparc64 to function again.
581	6745 d 21 h	palkovsky	/kernel/trunk/	Small debug changes.
569	6747 d 10 h	jermar	/kernel/trunk/	sparc64 work. Implement functions for reading IMMU and DMMU TLBs.
534	6751 d 13 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6751 d 14 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6763 d 18 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
493	6764 d 11 h	jermar	/SPARTAN/trunk/	Move genarch/{src\|include}/firmware/ofw to genarch/{src\|include}/ofw.
475	6775 d 19 h	jermar	/SPARTAN/trunk/	Define atomic_t type.
421	6791 d 9 h	jermar	/SPARTAN/trunk/	Create genarch directory. Move ppc32 ofw.[ch] to genarch. Fix prototype for ofw_call() to return __address instead of int (please review). Fix copyright notice in sparc64/boot/boot.S.
414	6799 d 0 h	jermar	/SPARTAN/trunk/	Create generic context_save() and context_restore(). These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively. The main purpose of this is to enable centralized commenting of these important and tricky functions.
413	6799 d 10 h	jermar	/SPARTAN/trunk/	Rename cpu_priority_{high\|low\|restore\|read} functions to interrupts_{disable\|enable\|restore\|read}. Rename pri_t to ipl_t (Interrupt Priority Level). Rename thread_t::pri to thread_t::priority.
