2440 6367 d 20 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().		  
2436 6368 d 21 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 6381 d 7 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.		  
2319 6389 d 7 h decky /trunk/kernel/generic/src/console/ run mcall only on active CPUs  
2310 6391 d 22 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.		  
2285 6404 d 6 h jermar /trunk/kernel/generic/src/proc/ Formatting and indentation fixes.  
2275 6408 d 22 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2272 6409 d 23 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2268 6410 d 22 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.		  
2229 6420 d 3 h jermar /trunk/ Revert some of the changes introduced in revision 2209.
I think it is not correct to remove serialization of pseudo threads in printf_core.c.
With thread-level futex serialization, several pseudo threads running in one thread could easily deadlock
the task.

Add a dedicated futex serialization to thread1.c test only.		  
2227 6420 d 11 h decky /trunk/kernel/ start shutdown infrastructure  
2224 6420 d 17 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6420 d 17 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6420 d 20 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust		  
2218 6421 d 18 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)		  
2216 6421 d 21 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2211 6421 d 23 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2208 6421 d 23 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup		  
2187 6423 d 4 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2185 6423 d 5 h decky /trunk/ rename ipcc to tester
