883 6642 d 19 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Switch console to framebuffer (needs proper detection and initialization).
No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore.		  
867 6646 d 16 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.		  
756 6668 d 7 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.		  
730 6678 d 13 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6680 d 8 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
684 6691 d 16 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.		  
667 6701 d 11 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Rename saving_handler() to preemptible_handler()
and fix it to make sparc64 kernel preemptive.
Add two handlers for two fatal exceptions (i.e.
instruction_access_exception and mem_address_not_aligned.
Fix panic_printf() to not allocate its own register window.		  
664 6705 d 6 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
663 6705 d 18 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Initial interrupt_vector_trap handler and fixes needed to make it do the right thing (i.e. panic()).		  
646 6712 d 8 h jermar /kernel/trunk/ Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.

sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop.		  
640 6713 d 7 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
630 6715 d 11 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Register window clean, spill and fill handlers.		  
619 6717 d 5 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Functions for disabling/enabling MMU.
TLB initialization.
Identity mapping of first 4M for kernel.
Switch to kernel copy of trap table.		  
569 6722 d 8 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.		  
534 6726 d 11 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6726 d 11 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
529 6728 d 14 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add dummy trap tables.		  
501 6738 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6746 d 8 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6746 d 11 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
