1780 6748 d 13 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6769 d 16 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1621 6776 d 13 h vana /kernel/trunk/arch/ia64/ itanium faulting task kill  
1595 6776 d 23 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
 
1507 6780 d 16 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1295 6807 d 17 h jermar /kernel/trunk/arch/ia64/ Complete implementation of memcpy_from_uspace() and memcpy_to_uspace().
The memcpy() variants are based on the assembler output of the generic
_memcpy().
 
1288 6808 d 18 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1265 6812 d 17 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1053 6858 d 13 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1023 6859 d 12 h vana /kernel/trunk/ Itanium FPU active context switch  
993 6860 d 10 h jermar /kernel/trunk/arch/ia64/ Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.
 
962 6861 d 9 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Support for __SYSCALL4.
Fix user stack initial address.
 
958 6861 d 10 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.
 
921 6865 d 13 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.
 
915 6867 d 20 h jermar /kernel/trunk/arch/ia64/ ia64 work.
- Another item had to be allocated on stack to remember new value written to ar.bspstore.
Fix heavyweight interruption handler to calculate RSC.loadrs from the new value of ar.bspstore
instead from the old one.
Uncomment instructions switching ar.bspstore.
- Configure kernel with 512M of memory.
 
912 6869 d 10 h jermar /kernel/trunk/ ia64 work.

ivt.S:
Detect userspace stack in heavyweight handler and switch to kernel stack.
Remember the old stack pointer.
As for register stack, kernel stack is assumed still.
Fix alignment issues that showed when STACK_ITEMS was odd.
Fix ld8 instruction that did subtraction of 8 instead of addition of 8.

scheduler.c:
Change before_thread_runs_arch() to calculate address of top of the stack
for the interrupt handler.
 
534 6960 d 11 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6960 d 11 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6972 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
472 6985 d 16 h jermar /SPARTAN/trunk/ Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.
