2211 6312 d 16 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2210 6312 d 16 h decky /trunk/ use more useful values  
2209 6312 d 16 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2208 6312 d 16 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup
 
2193 6313 d 19 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)
 
2192 6313 d 19 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2188 6313 d 20 h decky /trunk/ new user space testing framework (unfinished)  
2187 6313 d 21 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2186 6313 d 21 h decky /trunk/uspace/tester/ rename ipcc.c to tester.c  
2185 6313 d 21 h decky /trunk/ rename ipcc to tester  
2184 6313 d 23 h decky /trunk/kernel/generic/src/lib/ add zetta (sextillion) prefix
make constants explicitly unsigned
 
2183 6314 d 18 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 6319 d 11 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.
 
2161 6321 d 14 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB bug during TSB refill.
When one wants to enable a TSB entry, he or she should set the
entry invalid bit to false, as opposed to setting it to true.
 
2160 6321 d 14 h decky /trunk/boot/arch/ remove duplicate dependency  
2144 6322 d 12 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB size.  
2143 6322 d 18 h jermar /trunk/kernel/arch/sparc64/include/ Remove unneeded enum member.  
2142 6322 d 19 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2141 6323 d 10 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.
 
2139 6323 d 11 h decky /trunk/contrib/toolchain/ move to GCC 4.1.2, make scripts really host platform independent
remove orphaned libobjc
