2183 6260 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 6326 d 5 h decky /trunk/kernel/generic/ avoid conflict with potential keyword  
2071 6338 d 3 h jermar /trunk/ (c) versus (C)  
2064 6352 d 1 h vana /trunk/ SIMICS added as a simulator kernel runs on  
1933 6430 d 2 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6430 d 3 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 6431 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.		  
1888 6463 d 6 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1875 6470 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 6528 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6535 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6549 d 11 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6551 d 12 h decky /kernel/trunk/ make kernel prints case consistent  
1708 6553 d 12 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6555 d 12 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 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1698 6557 d 3 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.		  
1693 6558 d 6 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1669 6561 d 6 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1628 6563 d 0 h decky /kernel/trunk/ fixes
