3675 5659 d 16 h svoboda /branches/tracing/ Merge latest trunk changes to tracing.  
2787 5912 d 22 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2745 5942 d 2 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2626 6036 d 4 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2471 6196 d 19 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2183 6269 d 22 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 6335 d 20 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2071 6347 d 18 h jermar /trunk/ (c) versus (C)  
2064 6361 d 16 h vana /trunk/ SIMICS added as a simulator kernel runs on  
1933 6439 d 17 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6439 d 18 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 6440 d 17 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 6479 d 18 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 6537 d 20 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6544 d 21 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6559 d 2 h jermar /kernel/trunk/ Cleanup of comments.  
1702 6566 d 0 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1698 6566 d 18 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.
 
1693 6567 d 21 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1628 6572 d 15 h decky /kernel/trunk/ fixes  
1625 6572 d 15 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1595 6573 d 6 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 6573 d 16 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1573 6574 d 21 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1507 6577 d 0 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1288 6605 d 2 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 6607 d 6 h palkovsky /kernel/trunk/generic/ Added commands for accessing ia32 portspace in irq top-half.  
1281 6607 d 16 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.
