1389 6607 d 2 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic		  
1384 6607 d 22 h decky /kernel/trunk/arch/ppc32/src/ ppc32 work
decrementer workaround
primitive TLB support		  
1383 6607 d 23 h decky /kernel/trunk/ ppc32: hardware memory mapping, kernel PHT refill fix  
1378 6609 d 7 h decky /kernel/trunk/arch/ppc32/ kernel identity mapping still to be done using BAT  
1374 6609 d 22 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)		  
1328 6614 d 6 h decky /kernel/trunk/arch/ppc32/src/ ppc32: TLB manipulation stub  
1304 6619 d 2 h palkovsky /kernel/trunk/arch/ Fix zone_merge_all in ppc architectures.  
1288 6623 d 9 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 6627 d 0 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6627 d 1 h decky /kernel/trunk/ PHT Refill handler  
1221 6635 d 22 h decky /kernel/trunk/ printf-related and other code cleanup  
1215 6636 d 1 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1196 6642 d 8 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1151 6653 d 10 h decky /kernel/trunk/arch/ppc32/src/mm/ ppc32: mark four first frames as unavailable  
1132 6665 d 2 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
972 6675 d 9 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6675 d 10 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
934 6677 d 4 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
867 6695 d 6 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 6701 d 1 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 6703 d 22 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
815 6709 d 8 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
793 6711 d 6 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 6716 d 21 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 6740 d 6 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 6757 d 10 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
534 6775 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6775 d 1 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 6775 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6787 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
493 6787 d 23 h jermar /SPARTAN/trunk/ Move genarch/{src|include}/firmware/ofw to genarch/{src|include}/ofw.  
421 6814 d 21 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 6849 d 7 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
342 6858 d 7 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
191 6871 d 3 h decky /SPARTAN/trunk/arch/ppc/ PPC memory size detection  
163 6884 d 7 h decky /SPARTAN/trunk/arch/ppc/ first booting ELF  
162 6884 d 9 h decky /SPARTAN/trunk/arch/ppc/ PPC linker script
