1793 6565 d 6 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 6567 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6575 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1766 6583 d 7 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6586 d 2 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 6589 d 6 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.		  
1735 6591 d 7 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6591 d 17 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 6592 d 10 h palkovsky /kernel/trunk/arch/ Let mouse work on amd64 too.  
1708 6593 d 6 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6595 d 6 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 6595 d 9 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6595 d 10 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6596 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1690 6598 d 21 h palkovsky /kernel/trunk/ Yet another fix with framebuffer.  
1684 6599 d 7 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1667 6601 d 1 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 6602 d 7 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1639 6602 d 15 h decky /kernel/trunk/arch/ia32/src/boot/ VESA VBE code cleanup, works in VMWare now  
1595 6603 d 10 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 6604 d 0 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 6604 d 22 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1540 6606 d 9 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 6607 d 5 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 6608 d 12 h decky /kernel/trunk/arch/ cleanup  
1474 6608 d 19 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1473 6608 d 22 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1411 6616 d 1 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 6619 d 20 h decky /kernel/trunk/ make hardware memory mapping more generic  
1371 6621 d 20 h decky /kernel/trunk/ unify the framebuffer API
use physical address as the base address for the framebuffer		  
1327 6626 d 3 h decky /kernel/trunk/ split framebuffer initialization and sysinfo registration  
1318 6626 d 21 h vana /kernel/trunk/ Sysinfo userspace interface  
1313 6627 d 5 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 6628 d 3 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 6628 d 5 h jermar /kernel/trunk/ Change coding style in vesa.c and do some minor changes.  
1303 6630 d 23 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 6633 d 3 h vana /kernel/trunk/arch/ia32/src/drivers/ new line only if no clrscr  
1292 6635 d 2 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1290 6635 d 4 h vana /kernel/trunk/arch/ VESA detection failure fix.

(Some headers)
