4420 6101 d 13 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4419)  
4296 6136 d 10 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4295)  
4201 6151 d 15 h trochtova /branches/dd/ changes in trunk (rev 4200) merged into dd branch  
4055 6175 d 14 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 6458 d 16 h decky /branches/dd/ device drivers branch  
3020 6459 d 6 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2802 6512 d 16 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.		  
2662 6616 d 6 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2637 6635 d 7 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2623 6645 d 12 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6645 d 13 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.		  
2601 6658 d 10 h jermar /trunk/kernel/generic/src/ipc/ Fix and improve two IPC related comments.  
2494 6781 d 6 h jermar /trunk/kernel/generic/ Implement a new mechanism for copying data between two address spaces based on
IPC. New system method IPC_M_DATA_SEND is introduced. The implementation is
generic and does not make use of any possible architecture optimizations such as
direct copy from one address space to another.		  
2472 6805 d 7 h jermar /trunk/kernel/generic/src/ipc/ Some left-over stuff from the last commit (IPC cleanup and improved
comments.)		  
2471 6805 d 7 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2310 6846 d 8 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.		  
2216 6876 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2183 6878 d 11 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.		  
2071 6956 d 6 h jermar /trunk/ (c) versus (C)  
1933 7048 d 6 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1923 7049 d 6 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.		  
1787 7146 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 7153 d 10 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 7167 d 14 h jermar /kernel/trunk/ Cleanup of comments.  
1735 7169 d 16 h decky /kernel/trunk/ make kernel prints case consistent  
1708 7171 d 16 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 7173 d 15 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 7174 d 12 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 7181 d 19 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1591 7182 d 5 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1582 7182 d 16 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1573 7183 d 10 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1568 7183 d 11 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.		  
1502 7185 d 14 h jermar /kernel/trunk/ Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.
O		  
1364 7201 d 13 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1342 7202 d 18 h jermar /kernel/trunk/generic/ Improve comments.  
1281 7216 d 5 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.  
1260 7219 d 5 h palkovsky /kernel/trunk/ Small fixes.  
1258 7219 d 5 h palkovsky /kernel/trunk/ Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.		  
1223 7225 d 14 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().
