2745 5934 d 4 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 5955 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 6085 d 5 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2465 6198 d 1 h jermar /trunk/ Merge arm32 into trunk.  
2444 6205 d 16 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2183 6262 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 6266 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2142 6270 d 1 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6314 d 17 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6314 d 20 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2124 6314 d 21 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6321 d 0 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2107 6322 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 6323 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 6327 d 22 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6327 d 22 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6329 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2085 6335 d 1 h decky /trunk/kernel/ typedef elimination  
2083 6335 d 2 h decky /trunk/kernel/ typedef elimination  
2071 6339 d 19 h jermar /trunk/ (c) versus (C)
