4221 5614 d 11 h trochtova /branches/dd/ Added missing file.  
4156 5629 d 8 h trochtova /branches/dd/ changes in trunk (rev 4155) merged into dd branch  
4055 5640 d 10 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 5923 d 12 h decky /branches/dd/ device drivers branch  
2860 5967 d 3 h cejka /trunk/ Context handling unified for sparc64.  
2745 6015 d 11 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 6036 d 9 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)
 
2610 6118 d 7 h jermar /trunk/ Support for six syscall arguments for sparc64.
There is a minor stability issue which needs to be fixed (kernel panics upon entering kconsole from the
console task).
 
2510 6190 d 3 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.
 
2462 6281 d 3 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2272 6329 d 5 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2267 6331 d 4 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6331 d 4 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6333 d 2 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 6339 d 7 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.
 
2228 6339 d 9 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6339 d 17 h decky /trunk/kernel/ start shutdown infrastructure  
2170 6348 d 1 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 6350 d 4 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 6351 d 1 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB size.
