1731 6525 d 9 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation.		  
1708 6526 d 22 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6528 d 22 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1703 6529 d 2 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6529 d 19 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6537 d 1 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6537 d 2 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.		  
1587 6537 d 16 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.		  
1511 6540 d 19 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1410 6549 d 20 h jermar /kernel/trunk/arch/sparc64/ Modify sparc64 to choose optimal page size in each invocation of hw_map().
Use hw_map() to map keyboard device memory.		  
1377 6554 d 20 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Remove unneeded macro.  
1288 6568 d 22 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 6572 d 20 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1185 6590 d 19 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6590 d 19 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.		  
1171 6592 d 1 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1108 6612 d 11 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1104 6612 d 16 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1082 6617 d 14 h jermar /kernel/trunk/arch/sparc64/include/ Fix atomic_postdec() operation.  
1070 6618 d 0 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1024 6619 d 15 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
977 6620 d 20 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6620 d 23 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
958 6621 d 14 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.		  
955 6621 d 14 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
940 6622 d 15 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6622 d 15 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
910 6629 d 20 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
901 6633 d 23 h jermar /kernel/trunk/arch/ ia64 work.
Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler.
Add before_thread_runs_arch() that maps kstack, if necessary.
Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.		  
897 6635 d 10 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
895 6635 d 13 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.		  
894 6635 d 17 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6635 d 21 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.		  
889 6636 d 20 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Forgotten fb.h for sparc64.  
883 6636 d 22 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Switch console to framebuffer (needs proper detection and initialization).
No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore.		  
877 6638 d 14 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.		  
873 6638 d 22 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose.		  
867 6640 d 19 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
864 6641 d 10 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6641 d 10 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.
