2083 6381 d 3 h decky /trunk/kernel/ typedef elimination  
2082 6381 d 3 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6381 d 22 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6385 d 20 h jermar /trunk/ (c) versus (C)  
2057 6413 d 7 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.		  
2018 6422 d 23 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2007 6432 d 18 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 6434 d 1 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1958 6468 d 3 h decky /trunk/kernel/arch/amd64/ amd64: adopt new IRQ interface  
1949 6473 d 3 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6473 d 6 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1940 6477 d 0 h decky /trunk/kernel/arch/amd64/ amd64: fix compilation, keyboard not checked yet  
1891 6506 d 18 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6507 d 5 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 6507 d 20 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 6510 d 23 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6512 d 3 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6527 d 6 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 6563 d 4 h decky /trunk/kernel/arch/ unify bootstrapping  
1787 6575 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6582 d 23 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1731 6599 d 16 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 6603 d 5 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 6604 d 2 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1697 6604 d 21 h palkovsky /kernel/trunk/arch/ Fixed incorrect atomic_postinc/postdec...again...  
1692 6606 d 0 h palkovsky /kernel/trunk/arch/amd64/include/ Fix prein/predec instructions to be the same as on ia32.  
1595 6611 d 9 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 6615 d 2 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1477 6616 d 11 h decky /kernel/trunk/arch/ cleanup  
1473 6616 d 21 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1423 6621 d 3 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6624 d 0 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 6643 d 1 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1289 6643 d 3 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6643 d 5 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 6649 d 2 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 6650 d 2 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 6655 d 23 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6661 d 0 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.		  
1201 6661 d 1 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.
