1780 6699 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1766 6707 d 10 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6710 d 4 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 6713 d 9 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.		  
1735 6715 d 9 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6715 d 19 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 6716 d 12 h palkovsky /kernel/trunk/arch/ Let mouse work on amd64 too.  
1708 6717 d 9 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6719 d 8 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 6719 d 12 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6719 d 12 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6720 d 5 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1690 6722 d 23 h palkovsky /kernel/trunk/ Yet another fix with framebuffer.  
1684 6723 d 10 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1667 6725 d 4 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 6726 d 9 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1639 6726 d 18 h decky /kernel/trunk/arch/ia32/src/boot/ VESA VBE code cleanup, works in VMWare now  
1595 6727 d 12 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 6728 d 3 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 6729 d 0 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1540 6730 d 12 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).		  
1502 6731 d 7 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 6732 d 15 h decky /kernel/trunk/arch/ cleanup  
1474 6732 d 22 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1473 6733 d 0 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1411 6740 d 3 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 6743 d 23 h decky /kernel/trunk/ make hardware memory mapping more generic  
1371 6745 d 22 h decky /kernel/trunk/ unify the framebuffer API
use physical address as the base address for the framebuffer		  
1327 6750 d 5 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1318 6751 d 0 h vana /kernel/trunk/ Sysinfo userspace interface  
1313 6751 d 7 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().		  
1311 6752 d 5 h jermar /kernel/trunk/arch/ia32/src/drivers/ Fix number of frames allocated for VESA frame buffer in the singular
case when the frame buffer size is below FRAME_SIZE.		  
1310 6752 d 7 h jermar /kernel/trunk/ Change coding style in vesa.c and do some minor changes.  
1303 6755 d 2 h palkovsky /kernel/trunk/arch/ zone_merge_all must be called after frame_init is completed - otherwise
new zone information can be allocated over the not-yet-blacklisted areas.		  
1296 6757 d 6 h vana /kernel/trunk/arch/ia32/src/drivers/ new line only if no clrscr  
1292 6759 d 5 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1290 6759 d 6 h vana /kernel/trunk/arch/ VESA detection failure fix.

(Some headers)		  
1289 6759 d 6 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6759 d 8 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.		  
1287 6759 d 9 h vana /kernel/trunk/ ia32 VESA FB support
