2452 6175 d 23 h jermar /trunk/kernel/ More suncc fixes.
- Removed extra semicolons after function declaration.
- Sun Studio recognizes only C99 __func__ and no gcc-specific __FUNCTION__.
In this case, a simple -D option can fix the problem.
 
2451 6176 d 17 h jermar /trunk/kernel/generic/ JoinMe -> Lingering  
2449 6179 d 4 h decky /trunk/uspace/rd/ remove unnecessary includes  
2447 6179 d 21 h jermar /trunk/kernel/generic/src/main/ Split accidently joined lines.  
2446 6179 d 21 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 6179 d 22 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2444 6180 d 13 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2443 6180 d 14 h jermar /trunk/ sscc -> suncc  
2442 6180 d 15 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2441 6180 d 15 h decky /trunk/kernel/ fix ICC compilation  
2440 6180 d 15 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 6180 d 15 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6180 d 15 h decky /trunk/ update for new compiler configuration scheme  
2437 6180 d 16 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)
 
2436 6181 d 17 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 6194 d 2 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2321 6201 d 22 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2319 6202 d 2 h decky /trunk/kernel/generic/src/console/ run mcall only on active CPUs  
2317 6202 d 13 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6202 d 14 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs
