2216 6261 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2183 6264 d 3 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 6330 d 1 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2071 6341 d 22 h jermar /trunk/ (c) versus (C)  
2064 6355 d 21 h vana /trunk/ SIMICS added as a simulator kernel runs on  
1933 6433 d 22 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6433 d 22 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 6434 d 22 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 6467 d 2 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1875 6473 d 23 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 6532 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6539 d 2 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6553 d 6 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6555 d 8 h decky /kernel/trunk/ make kernel prints case consistent  
1708 6557 d 8 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6559 d 7 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 6560 d 4 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1698 6560 d 23 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.		  
1693 6562 d 2 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1669 6565 d 2 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.
