3836 5723 d 17 h decky /trunk/kernel/arch/ppc32/src/mm/ use secondary hash for kernel identity mapping to avoid livelocks on colliding PHT addresses  
3833 5724 d 12 h decky /trunk/ avoid nasty race condition during page fault handling  
3830 5725 d 11 h decky /trunk/kernel/arch/ppc32/ ppc32: add support for cache disable page access control  
3827 5725 d 13 h decky /trunk/ remove tlbia instruction, which is unsupported by PowerPC 7450  
3790 5746 d 17 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 5747 d 6 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 5797 d 9 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3586 5802 d 17 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3584 5802 d 19 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 5938 d 9 h jermar /trunk/kernel/ cstyle fixes  
3071 5965 d 14 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
2725 6083 d 15 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 6084 d 13 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2222 6387 d 8 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 6395 d 7 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 6457 d 16 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6468 d 9 h jermar /trunk/ (c) versus (C)  
1787 6658 d 11 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6665 d 12 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1758 6679 d 12 h decky /kernel/trunk/arch/ppc32/src/mm/ remove ASIDs from Page Hash Table  
1743 6681 d 8 h decky /kernel/trunk/arch/ppc32/src/mm/ fix compiler warning  
1736 6681 d 17 h decky /kernel/trunk/arch/ppc32/ verbose segment and BAT registers printout  
1733 6682 d 4 h decky /kernel/trunk/arch/ppc32/src/mm/ fix segment register values, ppc32 works again (both w/ and w/o BAT)  
1730 6682 d 5 h decky /kernel/trunk/arch/ppc32/ ppc32: BAT-less memory mapping (broken yet)
VSID support (broken yet)
boot API change
cleanup		  
1726 6682 d 12 h decky /kernel/trunk/arch/ppc32/ ppc32: more generic page hash table handling
(preliminary code, will be fixed properly later)		  
1716 6683 d 9 h decky /kernel/trunk/ move ppc32 four pages up, move real mode code, change config  
1708 6683 d 18 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6685 d 18 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 6686 d 15 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1609 6693 d 16 h decky /kernel/trunk/arch/ppc32/ generalize ppc32 exception handling  
1411 6706 d 12 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 6709 d 10 h decky /kernel/trunk/arch/ppc32/src/mm/ fixes  
1389 6709 d 10 h decky /kernel/trunk/ minor changes
ppc32: identically map the whole physical memory
fix page hash table refill logic		  
1384 6710 d 6 h decky /kernel/trunk/arch/ppc32/src/ ppc32 work
decrementer workaround
primitive TLB support		  
1383 6710 d 7 h decky /kernel/trunk/ ppc32: hardware memory mapping, kernel PHT refill fix  
1378 6711 d 15 h decky /kernel/trunk/arch/ppc32/ kernel identity mapping still to be done using BAT  
1374 6712 d 6 h decky /kernel/trunk/arch/ppc32/ ppc32 work
update framebuffer
get rid of the BAT memory mapping (not finished yet)		  
1328 6716 d 14 h decky /kernel/trunk/arch/ppc32/src/ ppc32: TLB manipulation stub  
1304 6721 d 11 h palkovsky /kernel/trunk/arch/ Fix zone_merge_all in ppc architectures.  
1288 6725 d 17 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.
