2193 6298 d 17 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)
 
2192 6298 d 18 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2191 6298 d 18 h kebrt /branches/arm/kernel/arch/arm32/include/ stack constants  
2190 6298 d 18 h kebrt /branches/arm/kernel/arch/arm32/include/ get_stack_base() added  
2189 6298 d 18 h kebrt /branches/arm/kernel/arch/arm32/ ARM CPU identification  
2188 6298 d 18 h decky /trunk/ new user space testing framework (unfinished)  
2187 6298 d 19 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2186 6298 d 20 h decky /trunk/uspace/tester/ rename ipcc.c to tester.c  
2185 6298 d 20 h decky /trunk/ rename ipcc to tester  
2184 6298 d 22 h decky /trunk/kernel/generic/src/lib/ add zetta (sextillion) prefix
make constants explicitly unsigned
 
2183 6299 d 16 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.
 
2182 6300 d 9 h jancik /branches/arm/kernel/arch/arm32/ Alf: Paging ... not tested

2175 6302 d 12 h jancik /branches/arm/kernel/arch/arm32/ Alf: Disable ASID support  
2174 6303 d 16 h kebrt /branches/arm/kernel/arch/arm32/include/ atomic_add added  
2173 6303 d 23 h kebrt /branches/arm/kernel/arch/arm32/ console added, does not work yet  
2172 6303 d 23 h kebrt /branches/arm/kernel/arch/arm32/src/ memcpy added  
2171 6303 d 23 h kebrt /branches/arm/kernel/arch/arm32/ memcpy added  
2170 6304 d 10 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.
