811	6706 d 0 h	jermar	/kernel/trunk/	Fix number of steps in softint division. Make ia64 port compile with softint.
810	6706 d 4 h	cejka	/kernel/trunk/genarch/	Added softint for emulation 32 and 64 bit division. Not tested yet.
793	6707 d 5 h	jermar	/kernel/trunk/	Use hash_table_get_instance instead of list_get_instance. Rename page_operations to page_mapping_operations. Rename page_pt_operations to pt_mapping_operations. Rename page_ht_operations to ht_mapping_operations.
792	6707 d 6 h	jermar	/kernel/trunk/	Page hash table architectures now use generic hash table to manage mappings.
788	6708 d 2 h	jermar	/kernel/trunk/	Move list and fifo data types to adt/.
786	6708 d 4 h	bondari	/kernel/trunk/	frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes. IMPORTANT: Parameter order for frame_alloc() was changed
778	6709 d 1 h	palkovsky	/kernel/trunk/	Fixed boot process not to call malloc when slab not initialized. Added simics workaround.
762	6711 d 6 h	palkovsky	/kernel/trunk/	Currently not-working SLAB allocator. - slightly changed interface to frame_alloc, allow zone preference
760	6711 d 7 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.
757	6711 d 23 h	jermar	/kernel/trunk/	Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator. This area contains VGA text frame buffer and should be avoided. falloc2 test now passes on ia64.
756	6712 d 20 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.
755	6713 d 19 h	jermar	/kernel/trunk/	Change page_mapping_find/insert interfaces to take as_t * as first argument and not asid_t as second argument. This change was necessitated by the removal of mapping array from as_area_t and the fact that an address space doesn't have an ASID when it is created.
753	6714 d 3 h	jermar	/kernel/trunk/	Convert ASID management of ia64 to ASID FIFO mechanism. 18-bit RIDs are supported.
746	6718 d 6 h	jermar	/kernel/trunk/	Page hash table modifications.
741	6719 d 23 h	jermar	/kernel/trunk/	Unlock address space prior TLB shootdown in get_asid() to unify the locking order among mips32, sparc64 and ia64. Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64 in a clean way.
740	6720 d 5 h	jermar	/kernel/trunk/	ia64 ASID management code (not tested).
730	6723 d 2 h	jermar	/kernel/trunk/	Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727	6724 d 22 h	jermar	/kernel/trunk/	New ASID management subsystem (initial work, more is required). Some TLB invalidation changes.
699	6734 d 7 h	jermar	/kernel/trunk/	Memory management work. Proto-interface and dummy implementation of generic page hash table subsytem.
689	6736 d 3 h	bondari	/kernel/trunk/	Frame alloc test #1
687	6736 d 4 h	jermar	/kernel/trunk/	Memory management work. Pass address space identifier to functions in page_operations to support single global page hash table.
684	6736 d 5 h	jermar	/kernel/trunk/	Memory management work. Move generic 4-level page table interface to genarch and enable architectures to use different virtual memory mechanisms (e.g. page hash tables). Start page hash table support. Switch ia64 and sparc64 to page hash tables. Other architectures keep on using 4-level page table interface.
669	6744 d 21 h	jermar	/kernel/trunk/	sparc64 work. kconsole support. Add non-blocking ofw_getchar().
659	6753 d 9 h	jermar	/kernel/trunk/	Make the kernel compile with -Wall.
534	6771 d 0 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6771 d 0 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
515	6781 d 1 h	jermar	/kernel/trunk/	SMP cleanup continued. Add nice type for IO APIC ID register. Replace some magic numbers with more descriptive macros.
512	6782 d 7 h	jermar	/kernel/trunk/	SMP work. Add madt_irq_to_pin(). Make ksmp() use virtual irq_to_pin() function, which makes better sence for ACPI configurations.
501	6783 d 5 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
494	6783 d 21 h	jermar	/SPARTAN/trunk/genarch/	Remove genarch/{src\|include}/firmware.
493	6783 d 22 h	jermar	/SPARTAN/trunk/	Move genarch/{src\|include}/firmware/ofw to genarch/{src\|include}/ofw.
492	6783 d 22 h	jermar	/SPARTAN/trunk/	Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find(). New names should make it more apparent that these two belong together.
458	6797 d 8 h	decky	/SPARTAN/trunk/	make configuration variables usage consistent
452	6798 d 0 h	decky	/SPARTAN/trunk/	major build system revision (unfinished) this patchset most definitively breaks a lot of things, be patient
430	6803 d 22 h	jermar	/SPARTAN/trunk/	Move src/ and include/ to generic.
426	6806 d 6 h	jermar	/SPARTAN/trunk/	sparc64 work. Add context_save(), context_set() and context_restore(). Remove putchar() definition from ofw.c. Add sparc64 putchar(). Add ppc32 putchar() (i.e. the original ofw.c putchar()). Make arg.h use the builtin va_* constructs.
424	6807 d 6 h	jermar	/SPARTAN/trunk/	sparc64 work. Link kernel with load address 0x4000. Add fragment of Linux image header to force SILO to always load the kernel at 0x4000. Adjust ofw.h and ofw.c to work also on sparc64.
422	6810 d 11 h	jermar	/SPARTAN/trunk/	Move ACPI code to genarch. Enable it for ia32, amd64 and ia64. For now, ia64 support is commented out.
421	6810 d 20 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.
