remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)

Make optionality of symbol information less intrusive per Jakub's request. Also, improve symtab function names and update their semantics.

Make kernel symbol information optional.

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()

make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64

overhaul pareas: use one single physical area for the physical address space not belonging to physical memory

very experimental TLB refill for ppc32

ppc32: strict coherency, compatible TLB flush
3839
5679 d 9 h
decky
/trunk/kernel/arch/ppc32/src/mm/
respect stricker lookup algorithm (first look for colliding PTEs, then look for unused PTEs)

make RANDI a generic macro
3837

use pseudorandom generator to avoid even the longest path of livelock collisions
3836
5679 d 10 h
decky
/trunk/kernel/arch/ppc32/src/mm/
use secondary hash for kernel identity mapping to avoid livelocks on colliding PHT addresses

avoid nasty race condition during page fault handling

ppc32: add support for cache disable page access control

remove tlbia instruction, which is unsupported by PowerPC 7450

Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.

svoboda
/trunk/kernel/
Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.

Handle page faults from userspace properly on ppc32, do not panic.

Do not print "Page fault.\n" if a mapping is not found during TLB refill.

Bugfix: A ppc32 task would hang if it touched unmapped memory - was calling printf() with address-space mutex held.
