2023 6374 d 4 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6384 d 1 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 6385 d 8 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6393 d 11 h decky /trunk/ make framebuffer code more generic  
1949 6424 d 10 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6424 d 13 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1930 6429 d 7 h decky /trunk/kernel/arch/ppc64/ ppc64: make it compile again  
1901 6450 d 8 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 6458 d 1 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6458 d 11 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 6459 d 3 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 6462 d 6 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6463 d 10 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6478 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.		  
1837 6503 d 15 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.		  
1802 6521 d 22 h decky /trunk/ cleanup and unify the build system  
1787 6527 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6534 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6542 d 13 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1760 6545 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...		  
1745 6550 d 2 h jermar /kernel/trunk/arch/ppc64/src/mm/ Make defunct ppc64 kernel compile again.  
1731 6550 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 6552 d 12 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6554 d 12 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 6554 d 15 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6555 d 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6562 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 6563 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.		  
1511 6566 d 8 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1475 6568 d 0 h jermar /kernel/trunk/arch/ Fix ppc32 and ppc64 to compile again.  
1474 6568 d 1 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1423 6572 d 10 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6575 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.		  
1399 6578 d 2 h decky /kernel/trunk/arch/ppc64/include/ small fixes  
1398 6578 d 3 h decky /kernel/trunk/arch/ port ppc32 changes to ppc64 (raw)  
1305 6589 d 10 h decky /kernel/trunk/arch/ppc64/ make ppc64 compile again  
1304 6590 d 5 h palkovsky /kernel/trunk/arch/ Fix zone_merge_all in ppc architectures.  
1298 6592 d 7 h vana /kernel/trunk/ FB endian fix  
1227 6606 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.		  
1221 6607 d 0 h decky /kernel/trunk/ printf-related and other code cleanup
