2082 6465 d 13 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6466 d 8 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6470 d 6 h jermar /trunk/ (c) versus (C)  
2057 6497 d 17 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.		  
2018 6507 d 9 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2007 6517 d 4 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 6518 d 11 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1958 6552 d 13 h decky /trunk/kernel/arch/amd64/ amd64: adopt new IRQ interface  
1949 6557 d 13 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6557 d 16 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1940 6561 d 9 h decky /trunk/kernel/arch/amd64/ amd64: fix compilation, keyboard not checked yet  
1891 6591 d 4 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6591 d 15 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 6592 d 6 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 6595 d 9 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6596 d 13 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6611 d 15 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.		  
1811 6647 d 14 h decky /trunk/kernel/arch/ unify bootstrapping  
1787 6660 d 8 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6667 d 9 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1731 6684 d 2 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 6687 d 15 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 6688 d 12 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1697 6689 d 7 h palkovsky /kernel/trunk/arch/ Fixed incorrect atomic_postinc/postdec...again...  
1692 6690 d 10 h palkovsky /kernel/trunk/arch/amd64/include/ Fix prein/predec instructions to be the same as on ia32.  
1595 6695 d 19 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.		  
1511 6699 d 12 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1477 6700 d 21 h decky /kernel/trunk/arch/ cleanup  
1473 6701 d 7 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1423 6705 d 13 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6708 d 9 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.		  
1292 6727 d 11 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1289 6727 d 13 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6727 d 15 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1256 6733 d 12 h jermar /kernel/trunk/arch/ Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults.		  
1251 6734 d 12 h jermar /kernel/trunk/ Fix BITS2BYTES macro to return 0 when passed 0 as argument.
Fix ia32 TSS segment granularity to be 0.
Fix ia32 and amd64 initial TSS limit to be 103.
Little textual changes here and there.		  
1212 6740 d 8 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6745 d 10 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.		  
1201 6745 d 11 h jermar /kernel/trunk/arch/ Fix amd64 and ia32 management of I/O bitmap in before_task_runs_arch()
by treating the iomap array as a bitmap. Make use of the bitmap type
and functions added in previous commit.		  
1187 6749 d 9 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.
