1760 6545 d 21 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...
 
1757 6549 d 0 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6551 d 2 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6551 d 12 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.
 
1712 6552 d 17 h palkovsky /kernel/trunk/generic/ Send to uspace notification about end of kconsole mode.  
1702 6555 d 22 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1693 6557 d 20 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1661 6561 d 4 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.
 
1643 6562 d 2 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1625 6562 d 14 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1595 6563 d 5 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.
 
1591 6563 d 14 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1587 6563 d 19 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.
 
1585 6563 d 23 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 6564 d 2 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1582 6564 d 2 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1579 6564 d 15 h jermar /kernel/trunk/generic/ Framework for task_kill().
Some pieces (e.g. implementation of ktask_cleanup() kernel thread and
task_destroy() function) are missing.
Changed locking order for task lock, threads_lock and thread lock from
threads_lock, thread lock, task lock to task lock, threads_lock, thread lock.
 
1576 6564 d 17 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1573 6564 d 20 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1571 6564 d 20 h jermar /kernel/trunk/generic/ thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing.
 
1568 6564 d 21 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1544 6565 d 23 h palkovsky /kernel/trunk/generic/ Slightly better behaviour with caching on memory sharing.  
1507 6566 d 23 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6567 d 0 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.

1494 6567 d 12 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1484 6567 d 22 h palkovsky /kernel/trunk/generic/include/ Added EINVAL error code.  
1474 6568 d 14 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1468 6568 d 20 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1461 6568 d 23 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1460 6569 d 0 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1440 6571 d 13 h palkovsky /kernel/trunk/generic/include/ Added error code for timeouts.  
1438 6571 d 14 h palkovsky /kernel/trunk/generic/ Correct realtime clock communication.  
1434 6571 d 18 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1431 6572 d 1 h jermar /kernel/trunk/generic/ Add missed_clock_ticks to CPU structure so that clock() can detect missed timer interrupts.
Architectures are required to support this in order to make time keeping accurate.
 
1429 6572 d 3 h jermar /kernel/trunk/generic/ Make ddi_physmem_map() accept address space area flags instead of writable switch.
Thus even these types of address space areas can turn caching on, if it is desired.
 
1428 6572 d 14 h palkovsky /kernel/trunk/generic/ Added 256K slab, so that AMD can boot (until ELF loader is fixed).
Added AS_AREA_RECV so that the caller can receive AS_AREA.
 
1425 6572 d 17 h jermar /kernel/trunk/generic/ Make address space backend data a union.  
1424 6572 d 19 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.
 
1423 6572 d 23 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1417 6574 d 15 h jermar /kernel/trunk/generic/ Modify as_area_share() to accept destination area flags bitmask from the sender
(i.e. the sender can limit access mode to the shared area for the recipient).
Modify IPC_M_AS_AREA_SEND code to support this. Arguments for sender: arg1=as_area,
arg2=size, arg3=flags_mask.

The mechanism seems to work, but the page fault handlers need to be altered to
distinguish between faults under different access modes.
