2436 6193 d 11 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 6205 d 20 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2319 6213 d 20 h decky /trunk/kernel/generic/src/console/ run mcall only on active CPUs  
2310 6216 d 12 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 6228 d 19 h jermar /trunk/kernel/generic/src/proc/ Formatting and indentation fixes.  
2275 6233 d 12 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2272 6234 d 12 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2268 6235 d 11 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2229 6244 d 17 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 6245 d 0 h decky /trunk/kernel/ start shutdown infrastructure  
2224 6245 d 7 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6245 d 7 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6245 d 10 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 6246 d 7 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 6246 d 10 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2211 6246 d 12 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2208 6246 d 13 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup
 
2187 6247 d 18 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2185 6247 d 18 h decky /trunk/ rename ipcc to tester  
2184 6247 d 20 h decky /trunk/kernel/generic/src/lib/ add zetta (sextillion) prefix
make constants explicitly unsigned
