2725 6040 d 1 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 6170 d 5 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2465 6283 d 1 h jermar /trunk/ Merge arm32 into trunk.  
2444 6290 d 16 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...		  
2183 6347 d 0 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 6351 d 17 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2142 6355 d 1 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6399 d 17 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6399 d 20 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2124 6399 d 21 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6406 d 0 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2107 6407 d 18 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 6408 d 2 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 6412 d 22 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6412 d 22 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6414 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2085 6420 d 1 h decky /trunk/kernel/ typedef elimination  
2083 6420 d 2 h decky /trunk/kernel/ typedef elimination  
2071 6424 d 19 h jermar /trunk/ (c) versus (C)  
2059 6448 d 4 h jermar /trunk/kernel/generic/ Improve indentation and formatting.
