2229 6249 d 16 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 6249 d 16 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.		  
2227 6250 d 0 h decky /trunk/kernel/ start shutdown infrastructure  
2225 6250 d 0 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 6250 d 6 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6250 d 6 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6250 d 9 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 6250 d 11 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6250 d 11 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 6250 d 12 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6251 d 7 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 6251 d 8 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 6251 d 10 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2211 6251 d 12 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2210 6251 d 12 h decky /trunk/ use more useful values  
2208 6251 d 12 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup		  
2188 6252 d 16 h decky /trunk/ new user space testing framework (unfinished)  
2187 6252 d 17 h decky /trunk/kernel/generic/ add syscall for getting current thread ID  
2185 6252 d 18 h decky /trunk/ rename ipcc to tester  
2184 6252 d 20 h decky /trunk/kernel/generic/src/lib/ add zetta (sextillion) prefix
make constants explicitly unsigned
