4581 5614 d 10 h mejdrech /branches/network/ Net: synchronized with trunk rev.4580  
4263 5693 d 9 h mejdrech /branches/network/ Net: merged with trunk:4261  
4153 5715 d 9 h mejdrech /branches/network/ Networking: merged with trunk changes  
3386 5911 d 12 h decky /branches/network/ add new network branch (copy of current trunk)  
3222 5968 d 12 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3186 5983 d 9 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.
 
3059 6003 d 13 h decky /trunk/kernel/generic/src/ proper printf formatting  
2916 6025 d 9 h jermar /trunk/kernel/generic/src/ More formatting changes.  
2914 6025 d 9 h jermar /trunk/kernel/generic/src/synch/ Formatting improvements.  
2909 6025 d 12 h jermar /trunk/kernel/generic/src/synch/ timeouted vs. timed out  
2745 6100 d 16 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2310 6396 d 9 h jermar /trunk/kernel/generic/ Cleanup the waitq_wakeup() interface.
Replace numeric constants (i.e. 0)
and boolean constants (i.e. false) with
more readable WAKEUP_FIRST. Also change the
type of the second argument of waitq_wakeup()
to a newly introduced type wakeup_mode_t.

Fix behaviour of waitq_wakeup() in case
that WAKEUP_ALL semantics is required
but no threads are sleeping in the wait
queue. This is a similar fix to that of
Jan Hudecek committed in the RCU branch,
but, IMHO, is more straightforward and
also doesn't eat up previous missed
wakeups.
 
2211 6426 d 10 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2183 6428 d 12 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.
 
2109 6488 d 16 h jermar /trunk/kernel/generic/ Revert thread_interrupt_sleep() to waitq_interrupt_sleep().
I'd prefer that this, IMO, waitq related stuff stays together.
 
2089 6495 d 15 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6496 d 11 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6506 d 8 h jermar /trunk/ (c) versus (C)  
2067 6516 d 13 h jermar /trunk/kernel/ More formatting changes.  
1888 6631 d 11 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
