1891 6509 d 23 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6510 d 10 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.		  
1889 6511 d 1 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support		  
1888 6514 d 4 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6515 d 8 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6516 d 9 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 6519 d 12 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1854 6530 d 10 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 6538 d 8 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 6541 d 11 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.  
1802 6573 d 21 h decky /trunk/ cleanup and unify the build system  
1787 6579 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6586 d 4 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6594 d 11 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1760 6597 d 6 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 6602 d 11 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6602 d 21 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 6604 d 10 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6606 d 10 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 6606 d 13 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6606 d 14 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6607 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1675 6611 d 9 h jermar /kernel/trunk/arch/ia64/ On ia64, purge DTR entry before overwriting it with new contents.  
1621 6614 d 4 h vana /kernel/trunk/arch/ia64/ itanium faulting task kill  
1611 6614 d 6 h jermar /kernel/trunk/arch/ia64/src/ ia64 memcpy that is unaligned pointer resistent.  
1601 6614 d 12 h jermar /kernel/trunk/ Support loading up to 8 userspace images on ia64.  
1595 6614 d 14 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 6615 d 4 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 6616 d 5 h vana /kernel/trunk/arch/ia64/src/ski/ Ia64 keyboard extension  
1548 6617 d 7 h vana /kernel/trunk/arch/ia64/src/ From/to kernel console switching on ia64  
1541 6617 d 13 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 6618 d 7 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1507 6618 d 7 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1495 6618 d 21 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1488 6619 d 4 h vana /kernel/trunk/arch/ia64/include/ Lost file  
1482 6619 d 8 h vana /kernel/trunk/arch/ia64/src/drivers/ Misseed clock ticks counting  
1474 6619 d 23 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1422 6624 d 10 h jermar /kernel/trunk/ Modify ia64 linker script to make compilation with gcc 4.1.x possible.  
1411 6627 d 5 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 6645 d 9 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().
