2447 6176 d 17 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6176 d 17 h jermar /trunk/kernel/generic/ More efficient and simpler task termination.

Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.

As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.

task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.

Change in the name of a thread state: Undead -> JoinMe.
 
2445 6176 d 18 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2444 6177 d 9 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2443 6177 d 10 h jermar /trunk/ sscc -> suncc  
2442 6177 d 11 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2441 6177 d 11 h decky /trunk/kernel/ fix ICC compilation  
2440 6177 d 11 h jermar /trunk/kernel/generic/ Fix the problem with sys_thread_create() by splitting the create and attach functionality of
thread_create(). Now it is possible to specify a flag that will cause thread_create() to only allocate and
initialize the thread structure. A call to thread_attach() will make the thread visible to the system.
This arrangement makes it easier to undo creation of a thread in case of a failure in sys_thread_create().
 
2439 6177 d 11 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6177 d 11 h decky /trunk/ update for new compiler configuration scheme  
2437 6177 d 11 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)
 
2436 6178 d 13 h jermar /trunk/ Fix two memory leaks.

In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.

In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up.
 
2359 6190 d 22 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2321 6198 d 17 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2319 6198 d 22 h decky /trunk/kernel/generic/src/console/ run mcall only on active CPUs  
2317 6199 d 9 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6199 d 9 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6199 d 10 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2310 6201 d 14 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.
 
2302 6204 d 15 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
