1389 6630 d 1 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic		  
1384 6630 d 21 h decky /kernel/trunk/arch/ppc32/src/ ppc32 work
decrementer workaround
primitive TLB support		  
1383 6630 d 21 h decky /kernel/trunk/ ppc32: hardware memory mapping, kernel PHT refill fix  
1378 6632 d 6 h decky /kernel/trunk/arch/ppc32/ kernel identity mapping still to be done using BAT  
1374 6632 d 20 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)		  
1328 6637 d 4 h decky /kernel/trunk/arch/ppc32/src/ ppc32: TLB manipulation stub  
1304 6642 d 1 h palkovsky /kernel/trunk/arch/ Fix zone_merge_all in ppc architectures.  
1288 6646 d 8 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1270 6649 d 23 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6650 d 0 h decky /kernel/trunk/ PHT Refill handler  
1221 6658 d 21 h decky /kernel/trunk/ printf-related and other code cleanup  
1215 6658 d 23 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1196 6665 d 6 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1151 6676 d 9 h decky /kernel/trunk/arch/ppc32/src/mm/ ppc32: mark four first frames as unavailable  
1132 6688 d 0 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
972 6698 d 8 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6698 d 8 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
934 6700 d 2 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
867 6718 d 5 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.		  
843 6723 d 23 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.		  
836 6726 d 20 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
815 6732 d 6 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
793 6734 d 4 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.		  
756 6739 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.		  
684 6763 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.		  
659 6780 d 8 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
534 6798 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6798 d 0 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)		  
532 6798 d 0 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6810 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
493 6810 d 21 h jermar /SPARTAN/trunk/ Move genarch/{src|include}/firmware/ofw to genarch/{src|include}/ofw.  
421 6837 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.		  
368 6872 d 6 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
342 6881 d 6 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
191 6894 d 2 h decky /SPARTAN/trunk/arch/ppc/ PPC memory size detection  
163 6907 d 6 h decky /SPARTAN/trunk/arch/ppc/ first booting ELF  
162 6907 d 8 h decky /SPARTAN/trunk/arch/ppc/ PPC linker script
