2188 6291 d 4 h decky /trunk/ new user space testing framework (unfinished)  
2187 6291 d 5 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2186 6291 d 6 h decky /trunk/uspace/tester/ rename ipcc.c to tester.c  
2185 6291 d 6 h decky /trunk/ rename ipcc to tester  
2184 6291 d 8 h decky /trunk/kernel/generic/src/lib/ add zetta (sextillion) prefix
make constants explicitly unsigned
 
2183 6292 d 2 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.

2171 6296 d 9 h kebrt /branches/arm/kernel/arch/arm32/ memcpy added  
2170 6296 d 20 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.

When one wants to enable a TSB entry, he or she should set the

Run this after downloading sources and before compilation.
