2440 6222 d 21 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 6222 d 22 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6222 d 22 h decky /trunk/ update for new compiler configuration scheme  
2437 6222 d 22 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)
 
2436 6223 d 23 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 6236 d 8 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2321 6244 d 4 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2319 6244 d 8 h decky /trunk/kernel/generic/src/console/ run mcall only on active CPUs  
2317 6244 d 20 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6244 d 20 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6244 d 20 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2310 6247 d 0 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 6250 d 1 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2301 6250 d 5 h decky /trunk/uspace/fb/ copy proper portion of viewport on screen border
(fixes ticket #34)
 
2285 6259 d 8 h jermar /trunk/kernel/generic/src/proc/ Formatting and indentation fixes.  
2275 6264 d 0 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2272 6265 d 1 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2268 6266 d 0 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2267 6267 d 0 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6267 d 0 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6268 d 22 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 6268 d 22 h jermar /trunk/boot/ Fix ticket #31.  
2237 6272 d 22 h jermar /trunk/boot/arch/sparc64/silo/ Upgrade SILO to 1.4.13.  
2233 6274 d 22 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6274 d 23 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6275 d 3 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 6275 d 3 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 6275 d 5 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 6275 d 5 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6275 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6275 d 13 h decky /trunk/contrib/conf/ MIPS boot image has grown  
2225 6275 d 13 h decky /trunk/kernel/arch/mips32/ the bss and common sections have to be in .data output section to be properly generated in the binary image
(this might break IRIX, but it is already unmaintaned)
 
2224 6275 d 19 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6275 d 19 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6275 d 22 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2221 6276 d 0 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6276 d 0 h decky /trunk/kernel/arch/ia32/src/boot/ check for PSE support, add error message on PSE not present
make initial mapping explicitly writeable, turn PAE explicitly off (just in case)
 
2219 6276 d 1 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6276 d 19 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)
 
2217 6276 d 20 h jermar /trunk/kernel/arch/ia32/src/smp/ On SMP amd64 and ia32 systems, release the irq->lock
before calling clock() from the interrupt handler.
This is important for maintaining kernel preemption
since no preemption can take place while a spinlock
is held.
