4327 5565 d 14 h mejdrech /branches/network/ Net: *merged with trunk 4326, +ne2k irq debug  
4263 5581 d 4 h mejdrech /branches/network/ Net: merged with trunk:4261  
4192 5592 d 1 h mejdrech /branches/network/ Net: ported dp8390, finished netif startup, enable irq explicitly while registering, improved integration, temporarily removed One module architecture, bug fixes  
4153 5603 d 3 h mejdrech /branches/network/ Networking: merged with trunk changes  
3386 5799 d 6 h decky /branches/network/ add new network branch (copy of current trunk)  
2745 5988 d 11 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2626 6082 d 13 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2471 6243 d 3 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2183 6316 d 7 h jermar /trunk/kernel/generic/ Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();

Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!

Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops.
 
2098 6382 d 5 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2071 6394 d 2 h jermar /trunk/ (c) versus (C)  
2064 6408 d 1 h vana /trunk/ SIMICS added as a simulator kernel runs on  
1933 6486 d 2 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6486 d 2 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 6487 d 2 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.
 
1875 6526 d 3 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 6584 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6591 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6605 d 10 h jermar /kernel/trunk/ Cleanup of comments.  
1702 6612 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1698 6613 d 3 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.
 
1693 6614 d 6 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1628 6618 d 23 h decky /kernel/trunk/ fixes  
1625 6619 d 0 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1595 6619 d 15 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 6620 d 1 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1573 6621 d 6 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1507 6623 d 9 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1288 6651 d 11 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.
 
1284 6653 d 15 h palkovsky /kernel/trunk/generic/ Added commands for accessing ia32 portspace in irq top-half.  
1281 6654 d 1 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.
