2233 6273 d 22 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6273 d 23 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6274 d 3 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.
 
2229 6274 d 6 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 6274 d 6 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6274 d 13 h decky /trunk/kernel/ start shutdown infrastructure  
2225 6274 d 14 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 6274 d 20 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6274 d 20 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6274 d 23 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 6275 d 0 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6275 d 0 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 6275 d 2 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6275 d 20 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 6275 d 21 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 6275 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2211 6276 d 1 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2210 6276 d 1 h decky /trunk/ use more useful values  
2208 6276 d 2 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup
 
2188 6277 d 6 h decky /trunk/ new user space testing framework (unfinished)
