1888 6504 d 22 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6506 d 2 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6521 d 4 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 6546 d 7 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 6564 d 14 h decky /trunk/ cleanup and unify the build system  
1787 6569 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6576 d 22 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6585 d 5 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1760 6587 d 23 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 6592 d 18 h jermar /kernel/trunk/arch/ppc64/src/mm/ Make defunct ppc64 kernel compile again.  
1731 6593 d 14 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 6595 d 4 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6597 d 4 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 6597 d 7 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6598 d 1 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6605 d 7 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 6605 d 22 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 6609 d 0 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1475 6610 d 16 h jermar /kernel/trunk/arch/ Fix ppc32 and ppc64 to compile again.  
1474 6610 d 17 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1423 6615 d 1 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6617 d 22 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 6620 d 18 h decky /kernel/trunk/arch/ppc64/include/ small fixes  
1398 6620 d 18 h decky /kernel/trunk/arch/ port ppc32 changes to ppc64 (raw)  
1305 6632 d 1 h decky /kernel/trunk/arch/ppc64/ make ppc64 compile again  
1304 6632 d 20 h palkovsky /kernel/trunk/arch/ Fix zone_merge_all in ppc architectures.  
1298 6634 d 23 h vana /kernel/trunk/ FB endian fix  
1227 6648 d 23 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 6649 d 16 h decky /kernel/trunk/ printf-related and other code cleanup  
1215 6649 d 19 h decky /kernel/trunk/arch/ ppc32: stub for Page Hash Table support  
1196 6656 d 2 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1191 6658 d 6 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1187 6658 d 21 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.		  
1185 6659 d 0 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6659 d 1 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.		  
1171 6660 d 6 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1165 6662 d 22 h decky /kernel/trunk/arch/ set ELF format explicitly  
1163 6662 d 23 h decky /kernel/trunk/arch/ fix types

1160 6662 d 23 h decky /kernel/trunk/ start ppc64 port
the code is currently a wild mixture of 32/64b code, will be fixed
