simple interrupt processing
 
2234 6314 d 9 h jancik /branches/arm/boot/arch/arm32/loader/ Alf: stabni kultura  
2233 6315 d 6 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6315 d 7 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6315 d 11 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 6315 d 11 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 6315 d 14 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 6315 d 14 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6315 d 21 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6315 d 21 h decky /trunk/contrib/conf/ MIPS boot image has grown  
2225 6315 d 21 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 6316 d 4 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6316 d 4 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6316 d 7 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 6316 d 8 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6316 d 8 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 6316 d 10 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6317 d 4 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 6317 d 5 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 6317 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2215 6317 d 8 h kebrt /branches/arm/kernel/arch/arm32/src/drivers/ gxemul.c renamed  
2214 6317 d 8 h kebrt /branches/arm/kernel/arch/arm32/ console_init() added, gxemul driver edited ("msim" string removed)  
2213 6317 d 8 h kebrt /branches/arm/kernel/arch/arm32/ static variables (e.g. 'last' in generic/../device.c) not initialized to zero when bss section separated  
2212 6317 d 8 h kebrt /branches/arm/kernel/generic/ aux_printf redirection removed  
2211 6317 d 9 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2210 6317 d 9 h decky /trunk/ use more useful values  
2209 6317 d 10 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2208 6317 d 10 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup
