3862 5909 d 3 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3665 5973 d 2 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3343 6078 d 9 h decky /branches/sparc/ add sparc branch  
3222 6120 d 9 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3186 6135 d 7 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 6155 d 11 h decky /trunk/kernel/generic/src/ proper printf formatting  
2916 6177 d 6 h jermar /trunk/kernel/generic/src/ More formatting changes.  
2914 6177 d 7 h jermar /trunk/kernel/generic/src/synch/ Formatting improvements.  
2909 6177 d 9 h jermar /trunk/kernel/generic/src/synch/ timeouted vs. timed out  
2745 6252 d 14 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2310 6548 d 7 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 6578 d 7 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2183 6580 d 9 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 6640 d 14 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 6647 d 12 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6648 d 8 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6658 d 5 h jermar /trunk/ (c) versus (C)  
2067 6668 d 11 h jermar /trunk/kernel/ More formatting changes.  
1888 6783 d 8 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1787 6848 d 7 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
