2316 6217 d 23 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6217 d 23 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2310 6220 d 3 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 6223 d 4 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2301 6223 d 8 h decky /trunk/uspace/fb/ copy proper portion of viewport on screen border
(fixes ticket #34)
 
2285 6232 d 11 h jermar /trunk/kernel/generic/src/proc/ Formatting and indentation fixes.  
2275 6237 d 3 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2272 6238 d 3 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2268 6239 d 3 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2267 6240 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6240 d 3 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6242 d 1 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.
 
2250 6242 d 1 h jermar /trunk/boot/ Fix ticket #31.  
2237 6246 d 0 h jermar /trunk/boot/arch/sparc64/silo/ Upgrade SILO to 1.4.13.  
2233 6248 d 1 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6248 d 1 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6248 d 5 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.
 
2230 6248 d 5 h jermar /trunk/uspace/ Remove printf() serialization from thread1 test in tester.
The agreement among developers seems to be that:
- there _must_ be a futex to serialize access to printf()
- there _must_ be pseudo thread serialization in printf()
- the best place for this is vprintf(), the one that goes to console
 
2229 6248 d 8 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.
 
2228 6248 d 8 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
