3836 5604 d 14 h decky /trunk/kernel/arch/ppc32/src/mm/ use secondary hash for kernel identity mapping to avoid livelocks on colliding PHT addresses  
3833 5605 d 10 h decky /trunk/ avoid nasty race condition during page fault handling  
3830 5606 d 9 h decky /trunk/kernel/arch/ppc32/ ppc32: add support for cache disable page access control  
3827 5606 d 10 h decky /trunk/ remove tlbia instruction, which is unsupported by PowerPC 7450  
3790 5627 d 15 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5628 d 4 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3594 5678 d 7 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3586 5683 d 14 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3584 5683 d 16 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Bugfix: A ppc32 task would hang if it touched unmapped memory - was calling printf() with address-space mutex held.  
3193 5819 d 7 h jermar /trunk/kernel/ cstyle fixes  
3071 5846 d 12 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2725 5964 d 13 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2723 5965 d 11 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2222 6268 d 6 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2170 6276 d 5 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.
 
2089 6338 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6349 d 6 h jermar /trunk/ (c) versus (C)  
1787 6539 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6546 d 10 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1758 6560 d 10 h decky /kernel/trunk/arch/ppc32/src/mm/ remove ASIDs from Page Hash Table  
1743 6562 d 6 h decky /kernel/trunk/arch/ppc32/src/mm/ fix compiler warning  
1736 6562 d 15 h decky /kernel/trunk/arch/ppc32/ verbose segment and BAT registers printout  
1733 6563 d 2 h decky /kernel/trunk/arch/ppc32/src/mm/ fix segment register values, ppc32 works again (both w/ and w/o BAT)  
1730 6563 d 3 h decky /kernel/trunk/arch/ppc32/ ppc32: BAT-less memory mapping (broken yet)
VSID support (broken yet)
boot API change
cleanup
 
1726 6563 d 10 h decky /kernel/trunk/arch/ppc32/ ppc32: more generic page hash table handling
(preliminary code, will be fixed properly later)
 
1716 6564 d 7 h decky /kernel/trunk/ move ppc32 four pages up, move real mode code, change config  
1708 6564 d 16 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6566 d 16 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 6567 d 13 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1609 6574 d 13 h decky /kernel/trunk/arch/ppc32/ generalize ppc32 exception handling  
1411 6587 d 10 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 6590 d 8 h decky /kernel/trunk/arch/ppc32/src/mm/ fixes  
1389 6590 d 8 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic
 
1384 6591 d 4 h decky /kernel/trunk/arch/ppc32/src/ ppc32 work
decrementer workaround
primitive TLB support
 
1383 6591 d 5 h decky /kernel/trunk/ ppc32: hardware memory mapping, kernel PHT refill fix  
1378 6592 d 13 h decky /kernel/trunk/arch/ppc32/ kernel identity mapping still to be done using BAT  
1374 6593 d 4 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)
 
1328 6597 d 12 h decky /kernel/trunk/arch/ppc32/src/ ppc32: TLB manipulation stub  
1304 6602 d 8 h palkovsky /kernel/trunk/arch/ Fix zone_merge_all in ppc architectures.  
1288 6606 d 15 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.
