2229 6304 d 3 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 6304 d 4 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.		  
2227 6304 d 11 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6304 d 11 h decky /trunk/contrib/conf/ MIPS boot image has grown  
2225 6304 d 11 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 6304 d 18 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6304 d 18 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6304 d 20 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 6304 d 22 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6304 d 22 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 6304 d 23 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6305 d 18 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 6305 d 19 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 6305 d 21 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2211 6305 d 23 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2210 6305 d 23 h decky /trunk/ use more useful values  
2209 6305 d 23 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup		  
2208 6305 d 23 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup		  
2193 6307 d 3 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)		  
2192 6307 d 3 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code
