2437 6217 d 0 h decky /trunk/ experimental support for ICC
(the sources has to be modified to avoid ICC compiler warnings)
 
2436 6218 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 6230 d 11 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2321 6238 d 6 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2319 6238 d 11 h decky /trunk/kernel/generic/src/console/ run mcall only on active CPUs  
2317 6238 d 22 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6238 d 22 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6238 d 23 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2310 6241 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 6244 d 4 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2285 6253 d 10 h jermar /trunk/kernel/generic/src/proc/ Formatting and indentation fixes.  
2275 6258 d 2 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2272 6259 d 3 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2268 6260 d 2 h jermar /trunk/kernel/generic/ Document and assert proper usage of THREAD_FLAG_WIRED.
Original patch by Jan Hudecek.
 
2267 6261 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix indentation.  
2266 6261 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6263 d 0 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 6269 d 0 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6269 d 1 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6269 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.
 
2229 6269 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.
 
2228 6269 d 7 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6269 d 15 h decky /trunk/kernel/ start shutdown infrastructure  
2225 6269 d 15 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 6269 d 21 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6269 d 21 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6270 d 0 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 6270 d 2 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6270 d 2 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 6270 d 3 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6270 d 22 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 6270 d 23 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.
 
2216 6271 d 1 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2211 6271 d 3 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2210 6271 d 3 h decky /trunk/ use more useful values  
2208 6271 d 3 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup
 
2188 6272 d 7 h decky /trunk/ new user space testing framework (unfinished)  
2187 6272 d 8 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2185 6272 d 9 h decky /trunk/ rename ipcc to tester  
2184 6272 d 11 h decky /trunk/kernel/generic/src/lib/ add zetta (sextillion) prefix
make constants explicitly unsigned
