4420	5646 d 20 h	trochtova	/branches/dd/	dd branch synchronized with trunk (revision 4419)
4156	5709 d 19 h	trochtova	/branches/dd/	changes in trunk (rev 4155) merged into dd branch
4055	5720 d 21 h	trochtova	/branches/dd/	changes in trunk (rev 4054) merged into dd branch
4042	5721 d 18 h	jermar	/trunk/	Complete emancipation of kernel serial controller drivers (i8042, ns16550 and z8530). Provide a common keyboard module for PC and Sun keyboards. The serial line module is still to follow.
3982	5728 d 15 h	jermar	/trunk/kernel/	Do not set sysinfo for uspace drivers directly in the kernel drivers.
3961	5734 d 18 h	jermar	/trunk/	Unbreak sparc64. Due to the lack of userspace bus drivers for the z8530 and ns16550, we are currently handling exactly one interrupt from these devices in userspace.
3941	5736 d 13 h	jermar	/trunk/kernel/	Let IRQ claim methods take irq_t * instead of the instance argument.
3906	5741 d 10 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.
3655	5819 d 13 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.
2089	6490 d 20 h	decky	/trunk/	huge type system cleanup remove cyclical type dependencies across multiple header files many minor coding style fixes
2071	6501 d 13 h	jermar	/trunk/	(c) versus (C)
1944	6591 d 16 h	jermar	/trunk/kernel/	Add mutual exclusion to keyboard grab and release functions on sparc64, ppc32, mips32 and ia64.
1932	6593 d 13 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.
1931	6593 d 14 h	jermar	/trunk/	Add support for IPC notifications even for polled ns16550 based keyboard.
1925	6594 d 12 h	jermar	/trunk/kernel/genarch/src/kbd/	Support for grabbing and releasing z8530 keyboard for sparc64. We might later add some locking.
1923	6594 d 13 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.
1921	6596 d 14 h	jermar	/trunk/kernel/	Changes in ns16550 and z8530 drivers. Add some stuff for IRQ notifications to irq_t.
1920	6596 d 22 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	6597 d 13 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.
1909	6608 d 13 h	jermar	/trunk/	Extend the OFW device tree node with a void pointer. The boot loader is supposed to reset all pointers in all nodes. The kernel uses the pointer to recognize that a particular device has already been visited and initialized. Read interrupt mapping from the OFW device tree for FHC devices (z8530) and EBUS devices (ns16550). In case of FHC devices, remove hardwired values from the code and use only values read from the tree. FHC initialization is started when a FHC device wants to map its interrupt. In case of EBUS devices, map the interrupt to INO. Interrupt enabling in the interrupt controller for that specific interrupt is not implemented yet.
