2232 6317 d 15 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6317 d 19 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 6317 d 19 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 6317 d 21 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 6317 d 21 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6318 d 5 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6318 d 5 h decky /trunk/contrib/conf/ MIPS boot image has grown  
2225 6318 d 5 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 6318 d 11 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6318 d 11 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6318 d 14 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 6318 d 16 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6318 d 16 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 6318 d 17 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6319 d 12 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 6319 d 13 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 6319 d 15 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2215 6319 d 16 h kebrt /branches/arm/kernel/arch/arm32/src/drivers/ gxemul.c renamed  
2214 6319 d 16 h kebrt /branches/arm/kernel/arch/arm32/ console_init() added, gxemul driver edited ("msim" string removed)  
2213 6319 d 16 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 6319 d 16 h kebrt /branches/arm/kernel/generic/ aux_printf redirection removed  
2211 6319 d 17 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2210 6319 d 17 h decky /trunk/ use more useful values  
2209 6319 d 17 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2208 6319 d 17 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup
 
2207 6320 d 10 h jelen /branches/fs/boot/arch/ia32/ramdisk/ ramdisk file  
2206 6320 d 10 h jelen /branches/fs/kernel/generic/src/main/ ramdisk initialization  
2205 6320 d 10 h jelen /branches/fs/kernel/generic/src/lib/ ramdisk initialization  
2204 6320 d 11 h jelen /branches/fs/kernel/generic/include/lib/ ramdisk version flag 0->1  
2203 6320 d 11 h jelen /branches/fs/boot/arch/ia32/ Link to ramdisk, added fs module  
2202 6320 d 11 h jelen /branches/fs/boot/arch/ia32/grub/ Added fs module and ramdisk image  
2201 6320 d 13 h jancik /branches/arm/kernel/generic/ Alf: Temporary kernel hack ... redirecting kernel printf function to aux_printf to kernel prints was visible  
2200 6320 d 13 h jancik /branches/arm/kernel/arch/arm32/src/ Alf: nothing important arm32 ... comment unnesesary things, dummy.S each symbol have different address so you can found what function call fall down  
2199 6320 d 13 h jancik /branches/arm/kernel/arch/arm32/ Alf: Memory management update  
2198 6320 d 14 h jancik /branches/arm/ Alf: Start kernel at 0x8010 0000 with paging enabled  
2197 6320 d 19 h kebrt /branches/arm/kernel/arch/arm32/ linker script reverted & -fno-zero-initialized-in-bss added  
2196 6320 d 19 h kebrt /branches/arm/kernel/arch/arm32/ linker script reverted & -fno-zero-initialized-in-bss added  
2195 6320 d 19 h kebrt /branches/arm/kernel/arch/arm32/include/ comments & formatting  
2194 6320 d 19 h kebrt /branches/arm/kernel/arch/arm32/ linker script cleaned (not sure about all changes, but problem with stack_safe != 0 solved)  
2193 6320 d 20 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)
