2234 6298 d 21 h jancik /branches/arm/boot/arch/arm32/loader/ Alf: stabni kultura  
2233 6299 d 18 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2232 6299 d 19 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2231 6299 d 23 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 6299 d 23 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 6300 d 1 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 6300 d 1 h jermar /trunk/kernel/arch/sparc64/src/ Fix ticket #28.
In switch_to_userspace(), the uarg argument is in %i2, not in %i3.
 
2227 6300 d 9 h decky /trunk/kernel/ start shutdown infrastructure  
2226 6300 d 9 h decky /trunk/contrib/conf/ MIPS boot image has grown  
2225 6300 d 9 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 6300 d 15 h decky /trunk/kernel/generic/src/console/ detach joined thread  
2223 6300 d 15 h decky /trunk/kernel/generic/src/ add mcall0 command (calling a function on each CPU)  
2222 6300 d 18 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 6300 d 20 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6300 d 20 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 6300 d 21 h decky /trunk/kernel/arch/amd64/src/boot/ add error message on no long mode support  
2218 6301 d 16 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 6301 d 17 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 6301 d 19 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2215 6301 d 20 h kebrt /branches/arm/kernel/arch/arm32/src/drivers/ gxemul.c renamed  
2214 6301 d 20 h kebrt /branches/arm/kernel/arch/arm32/ console_init() added, gxemul driver edited ("msim" string removed)  
2213 6301 d 20 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 6301 d 20 h kebrt /branches/arm/kernel/generic/ aux_printf redirection removed  
2211 6301 d 21 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2210 6301 d 21 h decky /trunk/ use more useful values  
2209 6301 d 21 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2208 6301 d 21 h decky /trunk/kernel/generic/ use spinlock only on console output, not other print functions
cleanup
 
2207 6302 d 14 h jelen /branches/fs/boot/arch/ia32/ramdisk/ ramdisk file  
2206 6302 d 14 h jelen /branches/fs/kernel/generic/src/main/ ramdisk initialization

2203 6302 d 15 h jelen /branches/fs/boot/arch/ia32/ Link to ramdisk, added fs module  
2202 6302 d 15 h jelen /branches/fs/boot/arch/ia32/grub/ Added fs module and ramdisk image  
2201 6302 d 17 h jancik /branches/arm/kernel/generic/ Alf: Temporary kernel hack ... redirecting kernel printf function to aux_printf to kernel prints was visible  
2200 6302 d 17 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 6302 d 17 h jancik /branches/arm/kernel/arch/arm32/ Alf: Memory management update  
2198 6302 d 18 h jancik /branches/arm/ Alf: Start kernel at 0x8010 0000 with paging enabled  
2197 6302 d 23 h kebrt /branches/arm/kernel/arch/arm32/ linker script reverted & -fno-zero-initialized-in-bss added
