2230 6311 d 6 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 6311 d 8 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 6311 d 8 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.		  
2227 6311 d 16 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6311 d 16 h decky /trunk/contrib/conf/ MIPS boot image has grown  
2225 6311 d 16 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 6311 d 22 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6311 d 22 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6312 d 1 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 6312 d 3 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6312 d 3 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 6312 d 4 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6312 d 23 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 6313 d 0 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 6313 d 2 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2215 6313 d 3 h kebrt /branches/arm/kernel/arch/arm32/src/drivers/ gxemul.c renamed  
2214 6313 d 3 h kebrt /branches/arm/kernel/arch/arm32/ console_init() added, gxemul driver edited ("msim" string removed)  
2213 6313 d 3 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 6313 d 3 h kebrt /branches/arm/kernel/generic/ aux_printf redirection removed  
2211 6313 d 4 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock
