4348 5545 d 23 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
4344 5547 d 11 h svoboda /branches/dynload/ Merge trunk changes up to r3988 to dynload.  
4343 5547 d 11 h svoboda /branches/dynload/ Merged trunk changes up to r3925 to dynload.  
4342 5547 d 11 h svoboda /branches/dynload/ Merge trunk changes up to r3889 to dynload.  
3674 5692 d 10 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
2927 5896 d 22 h decky /branches/dynload/ added dynload branch  
2745 5974 d 20 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2626 6068 d 22 h jermar /trunk/kernel/generic/ Support for 5 payload arguments for IPC irq notifications and the pseudo code.  
2471 6229 d 13 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2183 6302 d 16 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 6368 d 14 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2071 6380 d 12 h jermar /trunk/ (c) versus (C)  
2064 6394 d 10 h vana /trunk/ SIMICS added as a simulator kernel runs on  
1933 6472 d 11 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6472 d 12 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 6473 d 11 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 6512 d 12 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 6570 d 14 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6577 d 15 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6591 d 20 h jermar /kernel/trunk/ Cleanup of comments.  
1702 6598 d 18 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1698 6599 d 12 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.
 
1693 6600 d 15 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1628 6605 d 9 h decky /kernel/trunk/ fixes  
1625 6605 d 9 h decky /kernel/trunk/ ppc32 uspace keyboard support  
1595 6606 d 0 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 6606 d 10 h palkovsky /kernel/trunk/generic/ Small updates to ipc.  
1573 6607 d 15 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.
 
1507 6609 d 18 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1288 6637 d 20 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 6640 d 0 h palkovsky /kernel/trunk/generic/ Added commands for accessing ia32 portspace in irq top-half.  
1281 6640 d 10 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.
