2266 6371 d 13 h jermar /trunk/kernel/arch/sparc64/src/mm/ Add few assertions to tsb.c and clean it up a little bit.  
2252 6373 d 11 h jermar /trunk/kernel/arch/sparc64/src/mm/ Move one MEMBAR instruction from a delay slot,
which is, due to SF Erratum #51, a potentionally
dangerous place for a MEMBAR to be.
 
2250 6373 d 11 h jermar /trunk/boot/ Fix ticket #31.  
2237 6377 d 10 h jermar /trunk/boot/arch/sparc64/silo/ Upgrade SILO to 1.4.13.  
2233 6379 d 11 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6379 d 11 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6379 d 15 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.
 
2230 6379 d 15 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 6379 d 18 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 6379 d 18 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6380 d 1 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6380 d 2 h decky /trunk/contrib/conf/ MIPS boot image has grown  
2225 6380 d 2 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 6380 d 8 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6380 d 8 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6380 d 11 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 6380 d 12 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6380 d 12 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 6380 d 14 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6381 d 8 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)
