1968 6469 d 8 h jermar /tags/ Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories.
The change now should reflect how those releases looked like after checkout.		  
1964 6469 d 9 h jermar /tags/0.2.0/ Tagging release 0.2.0  
1609 6612 d 17 h decky /kernel/trunk/arch/ppc32/ generalize ppc32 exception handling  
1411 6625 d 13 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1390 6628 d 11 h decky /kernel/trunk/arch/ppc32/src/mm/ fixes  
1389 6628 d 11 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic		  
1384 6629 d 7 h decky /kernel/trunk/arch/ppc32/src/ ppc32 work
decrementer workaround
primitive TLB support		  
1383 6629 d 8 h decky /kernel/trunk/ ppc32: hardware memory mapping, kernel PHT refill fix  
1378 6630 d 17 h decky /kernel/trunk/arch/ppc32/ kernel identity mapping still to be done using BAT  
1374 6631 d 7 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)		  
1328 6635 d 15 h decky /kernel/trunk/arch/ppc32/src/ ppc32: TLB manipulation stub  
1304 6640 d 12 h palkovsky /kernel/trunk/arch/ Fix zone_merge_all in ppc architectures.  
1288 6644 d 18 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 6648 d 9 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6648 d 11 h decky /kernel/trunk/ PHT Refill handler  
1221 6657 d 7 h decky /kernel/trunk/ printf-related and other code cleanup  
1215 6657 d 10 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1196 6663 d 17 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1151 6674 d 19 h decky /kernel/trunk/arch/ppc32/src/mm/ ppc32: mark four first frames as unavailable  
1132 6686 d 11 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
972 6696 d 19 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization		  
970 6696 d 19 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
934 6698 d 13 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)		  
867 6716 d 15 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 6722 d 10 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 6725 d 7 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
815 6730 d 17 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
793 6732 d 15 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 6738 d 6 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 6761 d 15 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 6778 d 19 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
534 6796 d 11 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6796 d 11 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 6796 d 11 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6808 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
493 6809 d 8 h jermar /SPARTAN/trunk/ Move genarch/{src|include}/firmware/ofw to genarch/{src|include}/ofw.  
421 6836 d 6 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 6870 d 17 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
342 6879 d 16 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
191 6892 d 13 h decky /SPARTAN/trunk/arch/ppc/ PPC memory size detection
