2436 6193 d 1 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 10 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2321 6213 d 5 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2319 6213 d 10 h decky /trunk/kernel/generic/src/console/ run mcall only on active CPUs  
2317 6213 d 21 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6213 d 21 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6213 d 22 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2310 6216 d 2 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 6219 d 3 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2285 6228 d 9 h jermar /trunk/kernel/generic/src/proc/ Formatting and indentation fixes.  
2275 6233 d 2 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2272 6234 d 2 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2268 6235 d 1 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2267 6236 d 1 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6236 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6237 d 23 h jermar /trunk/kernel/arch/sparc64/src/mm/ Move one MEMBAR instruction from a delay slot,
which is, due to SF Erratum #51, a potentionally
dangerous place for a MEMBAR to be.
 
2233 6243 d 23 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6244 d 0 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6244 d 4 h jermar /trunk/kernel/arch/sparc64/ Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur.
 
2229 6244 d 7 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.
