867 6645 d 21 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.		  
838 6654 d 1 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6654 d 2 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
832 6657 d 13 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
811 6660 d 16 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.		  
810 6660 d 20 h cejka /kernel/trunk/genarch/ Added softint for emulation 32 and 64 bit division.
Not tested yet.		  
793 6661 d 21 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 6661 d 22 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
760 6665 d 23 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 6667 d 12 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 6668 d 11 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.		  
746 6672 d 22 h jermar /kernel/trunk/ Page hash table modifications.  
730 6677 d 18 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
699 6688 d 22 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
684 6690 d 21 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 6699 d 13 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
534 6725 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6725 d 16 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
515 6735 d 17 h jermar /kernel/trunk/ SMP cleanup continued.
Add nice type for IO APIC ID register.
Replace some magic numbers with more descriptive macros.		  
501 6737 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
494 6738 d 13 h jermar /SPARTAN/trunk/genarch/ Remove genarch/{src|include}/firmware.  
493 6738 d 14 h jermar /SPARTAN/trunk/ Move genarch/{src|include}/firmware/ofw to genarch/{src|include}/ofw.  
452 6752 d 16 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient		  
426 6760 d 22 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 6761 d 22 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 6765 d 3 h jermar /SPARTAN/trunk/ Move ACPI code to genarch.
Enable it for ia32, amd64 and ia64.
For now, ia64 support is commented out.		  
421 6765 d 12 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.
