1802 6654 d 13 h decky /trunk/ cleanup and unify the build system  
1793 6657 d 3 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.		  
1787 6659 d 20 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6666 d 21 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1766 6675 d 4 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6677 d 22 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...		  
1754 6681 d 3 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.		  
1735 6683 d 3 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6683 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.		  
1724 6684 d 6 h palkovsky /kernel/trunk/arch/ Let mouse work on amd64 too.  
1708 6685 d 3 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6687 d 3 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 6687 d 6 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6687 d 6 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6688 d 0 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1697 6688 d 18 h palkovsky /kernel/trunk/arch/ Fixed incorrect atomic_postinc/postdec...again...  
1691 6689 d 22 h palkovsky /kernel/trunk/arch/ia32/include/ Fix either bad compiler or bad code. The net result is better
optimization in GCC		  
1690 6690 d 18 h palkovsky /kernel/trunk/ Yet another fix with framebuffer.  
1684 6691 d 4 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1667 6692 d 22 h jermar /kernel/trunk/ Print spurious interrupt messages only when compiled with CONFIG_DEBUG.
Print warning about looping spinlock only after 100000000 unsuccessfull attempts to gain the spinlock.		  
1641 6694 d 4 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1639 6694 d 12 h decky /kernel/trunk/arch/ia32/src/boot/ VESA VBE code cleanup, works in VMWare now  
1595 6695 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 6695 d 21 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.		  
1576 6696 d 18 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1540 6698 d 6 h jermar /kernel/trunk/arch/ia32/src/smp/ Fix programming of local APIC timer to interrupt the processor
in the proper relation to HZ. (Was hardcoded to be each 1ms,
but should have been each 10ms).		  
1511 6698 d 23 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1502 6699 d 2 h jermar /kernel/trunk/ Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.
O		  
1477 6700 d 9 h decky /kernel/trunk/arch/ cleanup  
1474 6700 d 16 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1473 6700 d 18 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1468 6700 d 22 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1434 6703 d 20 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1423 6705 d 1 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6707 d 21 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.		  
1382 6711 d 17 h decky /kernel/trunk/ make hardware memory mapping more generic  
1371 6713 d 17 h decky /kernel/trunk/ unify the framebuffer API
use physical address as the base address for the framebuffer		  
1327 6717 d 23 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1318 6718 d 18 h vana /kernel/trunk/ Sysinfo userspace interface  
1313 6719 d 2 h jermar /kernel/trunk/ Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar().
