3343 5828 d 0 h decky /branches/sparc/ add sparc branch  
3222 5870 d 1 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3186 5884 d 22 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 5905 d 2 h decky /trunk/kernel/generic/src/ proper printf formatting  
2916 5926 d 22 h jermar /trunk/kernel/generic/src/ More formatting changes.  
2914 5926 d 22 h jermar /trunk/kernel/generic/src/synch/ Formatting improvements.  
2909 5927 d 1 h jermar /trunk/kernel/generic/src/synch/ timeouted vs. timed out  
2745 6002 d 5 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2310 6297 d 22 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 6327 d 23 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2183 6330 d 1 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 6390 d 5 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 6397 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6397 d 23 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6407 d 20 h jermar /trunk/ (c) versus (C)  
2067 6418 d 2 h jermar /trunk/kernel/ More formatting changes.  
1888 6533 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1787 6597 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6605 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6619 d 5 h jermar /kernel/trunk/ Cleanup of comments.
