4490	5629 d 11 h	decky	/trunk/kernel/	remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)
3947	5731 d 13 h	jermar	/trunk/	This is the evil commit. In particular, it does: - introduces more powerful pseudo code for userspace IRQ top-half handlers - changes the internals of IRQ dispatching - simplifies the kernel's i8042 driver - adapts the uspace i8042 driver to make use of the new pseudocode - breaks all other architectures except ia32 - breaks almost all existing drivers - breaks switching between uspace and kernel drivers
3941	5732 d 10 h	jermar	/trunk/kernel/	Let IRQ claim methods take irq_t * instead of the instance argument.
3906	5737 d 8 h	jermar	/trunk/kernel/	IRQ handlers are using one superfluous argument and an unused elipsis. On the other hand, IRQ claim functions would need to be passed the instance argument.
3875	5740 d 11 h	decky	/trunk/kernel/generic/	remove platform dependent constructs from generic code
3655	5815 d 11 h	jermar	/trunk/kernel/	Add additional members to the irq_t structure so that an interrupt-driven driver does not need to know how to clear the level interrupt. The z8530 was modified in this way and is much more generic. The ns16550 driver has also been modified, but awaits testing. The sparc64 interrupt mapping and dispatch code is now using the new info and calls the clear-interrupt-routine itself.
2218	6417 d 7 h	decky	/trunk/kernel/	support the possibility to send EOI or Interrupt Acknowledgement prior to processing the interrupt (this is essential on some architectures to prevent preemption deadlock)
2109	6479 d 19 h	jermar	/trunk/kernel/generic/	Revert thread_interrupt_sleep() to waitq_interrupt_sleep(). I'd prefer that this, IMO, waitq related stuff stays together.
2106	6480 d 18 h	jermar	/trunk/kernel/	Merge as_t structure into one and leave the differring parts in as_genarch_t. Indentation and formatting changes in header files.
2089	6486 d 17 h	decky	/trunk/	huge type system cleanup remove cyclical type dependencies across multiple header files many minor coding style fixes
2071	6497 d 10 h	jermar	/trunk/	(c) versus (C)
1923	6590 d 10 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.
1922	6591 d 18 h	jermar	/trunk/kernel/	More IRQ stuff. Modify the IRQ hash table functions to support lookup based on inr and devno. Add method member to irq_t.
1921	6592 d 11 h	jermar	/trunk/kernel/	Changes in ns16550 and z8530 drivers. Add some stuff for IRQ notifications to irq_t.
1920	6592 d 19 h	jermar	/trunk/kernel/	Move the new IRQ redirector to ddi/. Add function for assigning unique device numbers. Change sparc64/drivers/kbd.c to assign devno to keyboard.
1919	6593 d 10 h	jermar	/trunk/kernel/	Prototypical implementation of new IRQ redirector in sparc64. The new code can support shared IRQs in kernel (and multiple IRQs per device). Userspace support is yet to be written. The only architecture that uses this code is actually sparc64 only.
