1743 6552 d 3 h decky /kernel/trunk/arch/ppc32/src/mm/ fix compiler warning  
1736 6552 d 12 h decky /kernel/trunk/arch/ppc32/ verbose segment and BAT registers printout  
1733 6552 d 23 h decky /kernel/trunk/arch/ppc32/src/mm/ fix segment register values, ppc32 works again (both w/ and w/o BAT)  
1730 6553 d 0 h decky /kernel/trunk/arch/ppc32/ ppc32: BAT-less memory mapping (broken yet)
VSID support (broken yet)
boot API change
cleanup
 
1726 6553 d 7 h decky /kernel/trunk/arch/ppc32/ ppc32: more generic page hash table handling
(preliminary code, will be fixed properly later)
 
1716 6554 d 4 h decky /kernel/trunk/ move ppc32 four pages up, move real mode code, change config  
1708 6554 d 13 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6556 d 13 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1702 6557 d 10 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1609 6564 d 10 h decky /kernel/trunk/arch/ppc32/ generalize ppc32 exception handling  
1411 6577 d 7 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 6580 d 5 h decky /kernel/trunk/arch/ppc32/src/mm/ fixes  
1389 6580 d 5 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic
 
1384 6581 d 1 h decky /kernel/trunk/arch/ppc32/src/ ppc32 work
decrementer workaround
primitive TLB support
 
1383 6581 d 2 h decky /kernel/trunk/ ppc32: hardware memory mapping, kernel PHT refill fix  
1378 6582 d 10 h decky /kernel/trunk/arch/ppc32/ kernel identity mapping still to be done using BAT  
1374 6583 d 1 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)
 
1328 6587 d 9 h decky /kernel/trunk/arch/ppc32/src/ ppc32: TLB manipulation stub  
1304 6592 d 5 h palkovsky /kernel/trunk/arch/ Fix zone_merge_all in ppc architectures.  
1288 6596 d 12 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 6600 d 3 h decky /kernel/trunk/arch/ppc32/ page index and VSID fixes  
1269 6600 d 4 h decky /kernel/trunk/ PHT Refill handler  
1221 6609 d 1 h decky /kernel/trunk/ printf-related and other code cleanup  
1215 6609 d 4 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1196 6615 d 11 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1151 6626 d 13 h decky /kernel/trunk/arch/ppc32/src/mm/ ppc32: mark four first frames as unavailable  
1132 6638 d 5 h decky /kernel/trunk/arch/ppc32/ kernel boot API change  
972 6648 d 12 h decky /kernel/trunk/arch/ppc32/ ppc32: move kernel one frame up
frame zones initialization
 
970 6648 d 13 h decky /kernel/trunk/arch/ppc32/ ppc32: get memory map from loader  
934 6650 d 7 h decky /kernel/trunk/arch/ppc32/ remove all OpenFirmware bindings from ppc32 kernel code
kernel now runs in real mode (ppc32)
 
867 6668 d 9 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 6674 d 4 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 6677 d 1 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
815 6682 d 11 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
793 6684 d 9 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 6690 d 0 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 6713 d 9 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 6730 d 13 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
534 6748 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6748 d 4 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)
