2229 6255 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 6255 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 6255 d 21 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6255 d 21 h decky /trunk/contrib/conf/ MIPS boot image has grown  
2225 6255 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 6256 d 4 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6256 d 4 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6256 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 6256 d 8 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6256 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 6256 d 10 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6257 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 6257 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 6257 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2211 6257 d 9 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2210 6257 d 9 h decky /trunk/ use more useful values  
2209 6257 d 10 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup		  
2208 6257 d 10 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup		  
2193 6258 d 13 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)		  
2192 6258 d 13 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code
