1844 6555 d 14 h jermar /trunk/kernel/ Add an option to compile the sparc64 kernel for Ultra 5 or Enterprise E6500.
Basic keyboard support (polling) based on ns16550 serial port (deployed on Ultra).
 
1842 6555 d 19 h jermar /trunk/kernel/ i8042 and z8530 separated, the tree compiles again.
Now there is some duplicated code in i8042.c and z8530.c,
but that can be eliminated in slower pace.
 
1838 6560 d 17 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1837 6561 d 1 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.
 
1817 6571 d 8 h decky /trunk/kernel/arch/ xen32 work: create identity mapping for the main memory zone,
make several dummy modifications to get to the banner
 
1811 6571 d 21 h decky /trunk/kernel/arch/ unify bootstrapping  
1802 6579 d 8 h decky /trunk/ cleanup and unify the build system  
1793 6581 d 21 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 6584 d 15 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6591 d 16 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1766 6599 d 23 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6602 d 17 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 6605 d 22 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.
 
1735 6607 d 22 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6608 d 8 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 6609 d 1 h palkovsky /kernel/trunk/arch/ Let mouse work on amd64 too.  
1708 6609 d 22 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6611 d 21 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 6612 d 1 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6612 d 1 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6612 d 18 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1697 6613 d 13 h palkovsky /kernel/trunk/arch/ Fixed incorrect atomic_postinc/postdec...again...  
1691 6614 d 16 h palkovsky /kernel/trunk/arch/ia32/include/ Fix either bad compiler or bad code. The net result is better
optimization in GCC
 
1690 6615 d 12 h palkovsky /kernel/trunk/ Yet another fix with framebuffer.  
1684 6615 d 23 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1667 6617 d 17 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 6618 d 22 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1639 6619 d 7 h decky /kernel/trunk/arch/ia32/src/boot/ VESA VBE code cleanup, works in VMWare now  
1595 6620 d 1 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 6620 d 15 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 6621 d 13 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1540 6623 d 1 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 6623 d 18 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1502 6623 d 20 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.

1474 6625 d 11 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1473 6625 d 13 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1468 6625 d 17 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1434 6628 d 15 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1423 6629 d 19 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.
