2071 6337 d 21 h jermar /trunk/ (c) versus (C)  
2064 6351 d 20 h vana /trunk/ SIMICS added as a simulator kernel runs on  
1933 6429 d 20 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6429 d 21 h jermar /trunk/kernel/ Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code.
 
1923 6430 d 20 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.
 
1888 6463 d 0 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1875 6469 d 21 h jermar /trunk/ sparc64 work.
- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors.
 
1787 6527 d 23 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6535 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6549 d 5 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6551 d 6 h decky /kernel/trunk/ make kernel prints case consistent  
1708 6553 d 6 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6555 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.
 
1702 6556 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1698 6556 d 21 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.
 
1693 6558 d 0 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1669 6561 d 0 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1628 6562 d 18 h decky /kernel/trunk/ fixes  
1625 6562 d 18 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1595 6563 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.
 
1591 6563 d 19 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1582 6564 d 7 h palkovsky /kernel/trunk/generic/ Modified ipc_cleanup.  
1573 6565 d 0 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1568 6565 d 1 h palkovsky /kernel/trunk/generic/ Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator.
 
1507 6567 d 3 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1502 6567 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.

1461 6569 d 3 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1434 6571 d 23 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1428 6572 d 18 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.
 
1417 6574 d 20 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.
 
1413 6575 d 19 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.
 
1396 6578 d 21 h palkovsky /kernel/trunk/ Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().
 
1364 6583 d 3 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1359 6584 d 0 h jermar /kernel/trunk/generic/ Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.  
1346 6584 d 7 h palkovsky /kernel/trunk/generic/src/ipc/ Small updates to IPC regarding AS_SEND.  
1342 6584 d 8 h jermar /kernel/trunk/generic/ Improve comments.  
1329 6586 d 0 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1297 6593 d 2 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.
 
1293 6595 d 2 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6595 d 5 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.
