4537 5456 d 12 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4536)  
4201 5531 d 10 h trochtova /branches/dd/ changes in trunk (rev 4200) merged into dd branch  
4055 5555 d 8 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 5838 d 10 h decky /branches/dd/ device drivers branch  
2745 5930 d 10 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5951 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)		  
2556 6081 d 11 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2465 6194 d 6 h jermar /trunk/ Merge arm32 into trunk.  
2444 6201 d 22 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...		  
2183 6258 d 5 h jermar /trunk/kernel/generic/ Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();

Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!

Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops.		  
2170 6262 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.		  
2142 6266 d 6 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6310 d 23 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6311 d 1 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2124 6311 d 3 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6317 d 6 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2107 6319 d 0 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.		  
2106 6319 d 8 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.		  
2094 6324 d 4 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6324 d 4 h decky /trunk/kernel/ spinlock extern declaration macro
