3655	5644 d 18 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	6246 d 15 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)
2117	6308 d 0 h	decky	/trunk/kernel/generic/src/ddi/	explicit typecast
2107	6309 d 17 h	jermar	/trunk/	When clock() is called by an external interrupt dispatched by the IRQ dispatcher, no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24. Formating and indentation fixes.
2089	6316 d 1 h	decky	/trunk/	huge type system cleanup remove cyclical type dependencies across multiple header files many minor coding style fixes
2071	6326 d 18 h	jermar	/trunk/	(c) versus (C)
1933	6418 d 17 h	jermar	/trunk/kernel/generic/	Implement efficient IPC notification cleanup.
1923	6419 d 18 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	6421 d 2 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	6421 d 19 h	jermar	/trunk/kernel/	Changes in ns16550 and z8530 drivers. Add some stuff for IRQ notifications to irq_t.
1920	6422 d 3 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	6422 d 18 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.
