2984 5954 d 2 h svoboda /branches/dynload/ Add as_area_change_flags() syscall and libc wrapper. Implementation limited to non-shared areas of anonymous memory.  
2927 5961 d 5 h decky /branches/dynload/ added dynload branch  
2745 6039 d 3 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 6060 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 6190 d 4 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2465 6303 d 0 h jermar /trunk/ Merge arm32 into trunk.  
2444 6310 d 16 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...		  
2183 6366 d 23 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 6371 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2142 6375 d 0 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6419 d 16 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6419 d 19 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2124 6419 d 21 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6425 d 23 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2107 6427 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 6428 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 6432 d 22 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2093 6432 d 22 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6434 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2085 6440 d 0 h decky /trunk/kernel/ typedef elimination
