2725 5965 d 17 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)		  
2722 5966 d 16 h decky /trunk/kernel/arch/mips32/ convert ARC specific commands to generic ones  
2721 5966 d 17 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2696 5987 d 22 h decky /trunk/kernel/arch/mips32/ initial support for dorder device in MSIM  
2633 6032 d 6 h decky /trunk/kernel/arch/mips32/ CPU cycle accounting on MIPS  
2607 6047 d 15 h jermar /trunk/ Support for six syscall arguments on mips32.  
2467 6203 d 13 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.		  
2465 6208 d 16 h jermar /trunk/ Merge arm32 into trunk.  
2216 6270 d 11 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2089 6339 d 18 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2083 6345 d 18 h decky /trunk/kernel/ typedef elimination  
2082 6345 d 18 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6346 d 12 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6350 d 11 h jermar /trunk/ (c) versus (C)  
2057 6377 d 22 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.		  
2023 6387 d 12 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6397 d 9 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.		  
2003 6398 d 16 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1980 6410 d 19 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1955 6432 d 22 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1949 6437 d 18 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6437 d 21 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1936 6441 d 21 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1891 6471 d 9 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6471 d 19 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 6472 d 11 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 6475 d 14 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6476 d 18 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6477 d 18 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.		  
1854 6491 d 20 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.		  
1787 6540 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6547 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6547 d 16 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1769 6550 d 10 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.		  
1731 6564 d 6 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.		  
1705 6567 d 20 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1702 6568 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1686 6571 d 20 h decky /kernel/trunk/ update mips32 boot loading API  
1595 6576 d 0 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 6576 d 14 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.
