1789 6604 d 23 h jermar /trunk/ Fix ofw_memmap() in boot infrastructure.
The cell size is 32-bit and not equal sizeof(ofw_arg_t).
Define architecture dependant #address-cells and #size-cells for cases
the respective properties are missing in the OpenFirmware device tree.
The algorithm now works both for ppc32 and sparc64.

Add memmap_t, screen_t and keyboard_t to sparc64 bootinfo structure.
Be more verbose during sparc64 boot.

Move ALIGN_UP to generic part of boot/.

Change header guards in several places so that they don't contain double underscore.		  
1787 6606 d 19 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6607 d 17 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.		  
1780 6613 d 20 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1777 6613 d 23 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
1731 6630 d 13 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.

to be more like in the design documentation.		  
1708 6632 d 2 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6634 d 2 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 6634 d 6 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6634 d 23 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6642 d 5 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6642 d 6 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 6642 d 20 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 6645 d 23 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1410 6655 d 0 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 6660 d 0 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Remove unneeded macro.  
1288 6674 d 2 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 6678 d 0 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 6695 d 23 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6695 d 23 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 6697 d 5 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1108 6717 d 15 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
1104 6717 d 20 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 6722 d 18 h jermar /kernel/trunk/arch/sparc64/include/ Fix atomic_postdec() operation.  
1070 6723 d 4 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1024 6724 d 19 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
977 6725 d 23 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6726 d 3 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
958 6726 d 18 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 6726 d 18 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
940 6727 d 19 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6727 d 19 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
910 6735 d 0 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
901 6739 d 3 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 6740 d 14 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 6740 d 17 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 6740 d 20 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6741 d 1 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 6742 d 0 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Forgotten fb.h for sparc64.  
883 6742 d 2 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.
