2310 6170 d 17 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 6200 d 18 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2183 6202 d 20 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 6263 d 0 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 6269 d 23 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2087 6270 d 18 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6280 d 15 h jermar /trunk/ (c) versus (C)  
2067 6290 d 21 h jermar /trunk/kernel/ More formatting changes.  
1888 6405 d 19 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1787 6470 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6477 d 19 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6492 d 0 h jermar /kernel/trunk/ Cleanup of comments.  
1705 6498 d 1 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1702 6498 d 22 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1681 6502 d 12 h jermar /kernel/trunk/generic/src/synch/ Avoid tricky race condition between waitq_wakeup() and the pair
of waitq_timeouted_sleep() and waitq_interrupt_sleep().
Mutual exclusion != Synchronization.
 
1667 6503 d 20 h jermar /kernel/trunk/ Print spurious interrupt messages only when compiled with CONFIG_DEBUG.
Print warning about looping spinlock only after 100000000 unsuccessfull attempts to gain the spinlock.
 
1593 6506 d 12 h jermar /kernel/trunk/generic/src/synch/ When interrupted from sleep, pending timeouts must be unregistered.  
1586 6506 d 22 h jermar /kernel/trunk/generic/src/synch/ futex_cleanup() implementation.  
1583 6507 d 1 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1580 6507 d 4 h jermar /kernel/trunk/generic/src/ Update for task_kill().
