1881 6498 d 10 h jermar /trunk/ sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places

OpenFirmware work:
- two new functions for walking the device tree

Generic boot loader work:
- added basic string functions

Usual pile of indentation and formatting fixes.		  
1877 6501 d 13 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1854 6512 d 12 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.		  
1851 6520 d 9 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1850 6523 d 12 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.  
1802 6555 d 22 h decky /trunk/ cleanup and unify the build system  
1787 6561 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6568 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6576 d 13 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1760 6579 d 7 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...		  
1735 6584 d 12 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6584 d 22 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 6586 d 12 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6588 d 11 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1704 6588 d 15 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6588 d 15 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6589 d 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1675 6593 d 10 h jermar /kernel/trunk/arch/ia64/ On ia64, purge DTR entry before overwriting it with new contents.  
1621 6596 d 6 h vana /kernel/trunk/arch/ia64/ itanium faulting task kill  
1611 6596 d 7 h jermar /kernel/trunk/arch/ia64/src/ ia64 memcpy that is unaligned pointer resistent.  
1601 6596 d 14 h jermar /kernel/trunk/ Support loading up to 8 userspace images on ia64.  
1595 6596 d 15 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 6597 d 6 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.		  
1570 6598 d 6 h vana /kernel/trunk/arch/ia64/src/ski/ Ia64 keyboard extension  
1548 6599 d 8 h vana /kernel/trunk/arch/ia64/src/ From/to kernel console switching on ia64  
1541 6599 d 15 h jermar /kernel/trunk/ Modify ia64 to load 6 userspace tasks.
Tetris however makes the kernel fault on unaligned memory access in copy_from_uspace.		  
1511 6600 d 8 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1507 6600 d 9 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1495 6600 d 22 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1488 6601 d 5 h vana /kernel/trunk/arch/ia64/include/ Lost file  
1482 6601 d 9 h vana /kernel/trunk/arch/ia64/src/drivers/ Misseed clock ticks counting  
1474 6602 d 1 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1422 6606 d 11 h jermar /kernel/trunk/ Modify ia64 linker script to make compilation with gcc 4.1.x possible.  
1411 6609 d 6 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1295 6627 d 10 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().		  
1290 6628 d 9 h vana /kernel/trunk/arch/ VESA detection failure fix.

(Some headers)		  
1288 6628 d 11 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.		  
1280 6631 d 3 h jermar /kernel/trunk/arch/ Get rid off obsolete ddi_int_control_arch() on ia64, sparc64 and ppc32.  
1265 6632 d 10 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1227 6640 d 7 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.
