3478 5787 d 4 h decky /branches/arm/ new arm branch  
3222 5867 d 23 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3186 5882 d 20 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 5903 d 0 h decky /trunk/kernel/generic/src/ proper printf formatting  
2916 5924 d 20 h jermar /trunk/kernel/generic/src/ More formatting changes.  
2914 5924 d 20 h jermar /trunk/kernel/generic/src/synch/ Formatting improvements.  
2909 5924 d 23 h jermar /trunk/kernel/generic/src/synch/ timeouted vs. timed out  
2745 6000 d 3 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2310 6295 d 20 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 6325 d 21 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2183 6327 d 23 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 6388 d 3 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 6395 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6395 d 21 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6405 d 18 h jermar /trunk/ (c) versus (C)  
2067 6416 d 0 h jermar /trunk/kernel/ More formatting changes.  
1888 6530 d 22 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1787 6595 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6602 d 22 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6617 d 3 h jermar /kernel/trunk/ Cleanup of comments.
