4692 5540 d 20 h svoboda /branches/tracing/ Merge trunk changes up to r4686.  
4377 5640 d 20 h svoboda /branches/tracing/ Merge latest trunk changes to tracing. (i.e. revs 3684:4374, huge). This time hopefully the real thing.  
3624 5810 d 4 h svoboda /branches/tracing/kernel/ Move debbuging-related as functions to a separate module.  
3431 5877 d 18 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3425 5878 d 6 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3036 5984 d 23 h svoboda /branches/tracing/kernel/generic/ Make sure area written by debugger is private and anonymous by copying it, if necessary. (Not atomic atm)  
3013 5989 d 7 h svoboda /branches/tracing/kernel/generic/ Bypass area write-protection for udebug memory writes.  
2787 6050 d 23 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2745 6080 d 4 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2725 6101 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 6231 d 5 h jermar /trunk/kernel/generic/ Rename as_get_size() to as_area_get_size() and add a doxygen comment.  
2465 6344 d 1 h jermar /trunk/ Merge arm32 into trunk.  
2444 6351 d 16 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2183 6407 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 6412 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 6416 d 0 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2126 6460 d 17 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6460 d 19 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2124 6460 d 21 h decky /trunk/kernel/generic/ implement simple realloc()  
2122 6467 d 0 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison
