4138 5711 d 0 h jermar /trunk/ Revert the previous commit.  
3973 5729 d 9 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 5736 d 4 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3908 5740 d 2 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3790 5779 d 9 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 5779 d 22 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3672 5813 d 1 h jermar /trunk/ Merge sparc branch to trunk.  
3133 5988 d 0 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
 
3104 5995 d 13 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
2745 6095 d 9 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 6116 d 7 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)
 
2462 6361 d 0 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2272 6409 d 3 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2267 6411 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6411 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6413 d 0 h jermar /trunk/kernel/arch/sparc64/src/mm/ Move one MEMBAR instruction from a delay slot,
which is, due to SF Erratum #51, a potentionally
dangerous place for a MEMBAR to be.
 
2231 6419 d 5 h jermar /trunk/kernel/arch/sparc64/ Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur.
 
2170 6427 d 23 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.
 
2161 6430 d 1 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB bug during TSB refill.
When one wants to enable a TSB entry, he or she should set the
entry invalid bit to false, as opposed to setting it to true.
 
2144 6430 d 23 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB size.
