4490 5553 d 8 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4137 5631 d 7 h svoboda /trunk/kernel/ Make optionality of symbol information less intrusive per Jakub's request. Also, improve symtab function names and update their semantics.  
4132 5632 d 6 h svoboda /trunk/ Make kernel symbol information optional.  
3973 5649 d 16 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()
 
3940 5656 d 10 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3908 5660 d 9 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3857 5674 d 10 h decky /trunk/ very experimental TLB refill for ppc32  
3856 5674 d 11 h decky /trunk/ ppc32: strict coherency, compatible TLB flush  
3839 5676 d 14 h decky /trunk/kernel/arch/ppc32/src/mm/ respect stricker lookup algorithm (first look for colliding PTEs, then look for unused PTEs)  
3838 5676 d 14 h decky /trunk/kernel/ make RANDI a generic macro  
3837 5676 d 15 h decky /trunk/kernel/arch/ppc32/ use pseudorandom generator to avoid even the longest path of livelock collisions  
3836 5676 d 15 h decky /trunk/kernel/arch/ppc32/src/mm/ use secondary hash for kernel identity mapping to avoid livelocks on colliding PHT addresses  
3833 5677 d 11 h decky /trunk/ avoid nasty race condition during page fault handling  
3830 5678 d 9 h decky /trunk/kernel/arch/ppc32/ ppc32: add support for cache disable page access control  
3827 5678 d 11 h decky /trunk/ remove tlbia instruction, which is unsupported by PowerPC 7450  
3790 5699 d 16 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 5700 d 5 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 5750 d 8 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3586 5755 d 15 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3584 5755 d 17 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 5891 d 7 h jermar /trunk/kernel/ cstyle fixes  
3071 5918 d 13 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2725 6036 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 6037 d 12 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2222 6340 d 7 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 6348 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 6410 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6421 d 7 h jermar /trunk/ (c) versus (C)  
1787 6611 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6618 d 10 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1758 6632 d 10 h decky /kernel/trunk/arch/ppc32/src/mm/ remove ASIDs from Page Hash Table  
1743 6634 d 7 h decky /kernel/trunk/arch/ppc32/src/mm/ fix compiler warning  
1736 6634 d 16 h decky /kernel/trunk/arch/ppc32/ verbose segment and BAT registers printout  
1733 6635 d 3 h decky /kernel/trunk/arch/ppc32/src/mm/ fix segment register values, ppc32 works again (both w/ and w/o BAT)  
1730 6635 d 3 h decky /kernel/trunk/arch/ppc32/ ppc32: BAT-less memory mapping (broken yet)
VSID support (broken yet)
boot API change
cleanup
 
1726 6635 d 10 h decky /kernel/trunk/arch/ppc32/ ppc32: more generic page hash table handling
(preliminary code, will be fixed properly later)
 
1716 6636 d 8 h decky /kernel/trunk/ move ppc32 four pages up, move real mode code, change config  
1708 6636 d 16 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6638 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 6639 d 13 h cejka /kernel/trunk/ Kernel doxygen comments updated.
