4490 5473 d 13 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4137 5551 d 12 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 5552 d 10 h svoboda /trunk/ Make kernel symbol information optional.  
3973 5569 d 21 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 5576 d 15 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3908 5580 d 13 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3857 5594 d 14 h decky /trunk/ very experimental TLB refill for ppc32  
3856 5594 d 16 h decky /trunk/ ppc32: strict coherency, compatible TLB flush  
3839 5596 d 19 h decky /trunk/kernel/arch/ppc32/src/mm/ respect stricker lookup algorithm (first look for colliding PTEs, then look for unused PTEs)  
3838 5596 d 19 h decky /trunk/kernel/ make RANDI a generic macro  
3837 5596 d 19 h decky /trunk/kernel/arch/ppc32/ use pseudorandom generator to avoid even the longest path of livelock collisions  
3836 5596 d 20 h decky /trunk/kernel/arch/ppc32/src/mm/ use secondary hash for kernel identity mapping to avoid livelocks on colliding PHT addresses  
3833 5597 d 15 h decky /trunk/ avoid nasty race condition during page fault handling  
3830 5598 d 14 h decky /trunk/kernel/arch/ppc32/ ppc32: add support for cache disable page access control  
3827 5598 d 16 h decky /trunk/ remove tlbia instruction, which is unsupported by PowerPC 7450  
3790 5619 d 20 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 5620 d 9 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 5670 d 12 h svoboda /trunk/kernel/arch/ppc32/src/mm/ Handle page faults from userspace properly on ppc32, do not panic.  
3586 5675 d 20 h jermar /trunk/kernel/arch/ Do not print "Page fault.\n" if a mapping is not found during TLB refill.  
3584 5675 d 22 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.
