4420 5697 d 13 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4419)  
4296 5732 d 9 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4295)  
4201 5747 d 15 h trochtova /branches/dd/ changes in trunk (rev 4200) merged into dd branch  
4055 5771 d 14 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 6054 d 16 h decky /branches/dd/ device drivers branch  
3020 6055 d 6 h jermar /trunk/kernel/generic/ Turn phone->lock into mutex.  
2802 6108 d 16 h jermar /trunk/kernel/generic/ Fix initialization of answerbox->task in ipc_answerbox_init.
Contributed by Jiri Svoboda.
 
2662 6212 d 5 h jermar /trunk/ Add support for IPC_M_DATA_READ calls.  
2637 6231 d 7 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
 
2623 6241 d 12 h jermar /trunk/kernel/generic/ Introduce the IPC_FF_ROUTE_FROM_ME forwarding flag.  
2622 6241 d 12 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.
 
2601 6254 d 9 h jermar /trunk/kernel/generic/src/ipc/ Fix and improve two IPC related comments.  
2494 6377 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 6401 d 7 h jermar /trunk/kernel/generic/src/ipc/ Some left-over stuff from the last commit (IPC cleanup and improved
comments.)
 
2471 6401 d 7 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2310 6442 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 6472 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2183 6474 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 6552 d 6 h jermar /trunk/ (c) versus (C)  
1933 6644 d 5 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1923 6645 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 6742 d 8 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6749 d 9 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6763 d 14 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6765 d 16 h decky /kernel/trunk/ make kernel prints case consistent  
1708 6767 d 15 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6769 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 6770 d 12 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6777 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 6778 d 4 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1582 6778 d 16 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1573 6779 d 9 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1568 6779 d 11 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1502 6781 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 6797 d 13 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1342 6798 d 17 h jermar /kernel/trunk/generic/ Improve comments.  
1281 6812 d 5 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.  
1260 6815 d 4 h palkovsky /kernel/trunk/ Small fixes.  
1258 6815 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 6821 d 14 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().
