2107 6373 d 15 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.		  
2089 6379 d 23 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2083 6385 d 22 h decky /trunk/kernel/ typedef elimination  
2082 6385 d 23 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6386 d 17 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6390 d 15 h jermar /trunk/ (c) versus (C)  
2057 6418 d 3 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.		  
2023 6427 d 16 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6437 d 14 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 6438 d 20 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6446 d 23 h decky /trunk/ make framebuffer code more generic  
1980 6451 d 0 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1955 6473 d 3 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1949 6477 d 23 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6478 d 2 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1944 6480 d 18 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1936 6482 d 2 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6503 d 21 h jermar /trunk/kernel/ Make SMP related parts of main.c more generic.
Move initialization of local APIC to architecture specific code.
Add arch_post_cpu_init() to support the above.		  
1891 6511 d 14 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6512 d 0 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 6512 d 16 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 6515 d 19 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6516 d 23 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6517 d 23 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.		  
1871 6524 d 3 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.		  
1854 6532 d 1 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.		  
1837 6557 d 4 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.		  
1812 6567 d 22 h decky /trunk/kernel/ move macro and cleanup  
1802 6575 d 11 h decky /trunk/ cleanup and unify the build system  
1787 6580 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6587 d 19 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6587 d 21 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1769 6590 d 14 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.		  
1754 6602 d 1 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.		  
1749 6603 d 13 h decky /kernel/trunk/arch/mips32/src/ remove forgotten address translation  
1746 6603 d 14 h decky /kernel/trunk/ prepare GXEmul kernel to use the boot loader  
1742 6603 d 16 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad booting address on MIPS when not compiled in debug mode.  
1741 6603 d 16 h palkovsky /kernel/trunk/arch/mips32/src/drivers/ Fix panic if continue after non-initialized kbd.  
1735 6604 d 1 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6604 d 11 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.
