3790	5590 d 2 h	svoboda	/trunk/kernel/	Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.
3655	5629 d 17 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.
2745	5906 d 2 h	decky	/trunk/	code cleanup (mostly signed/unsigned) allow extra compiler warnings
2071	6311 d 17 h	jermar	/trunk/	(c) versus (C)
1912	6414 d 2 h	jermar	/trunk/kernel/	Separate mapping of EBUS interrupts into two parts: EBUS and PCI.
1910	6417 d 15 h	jermar	/trunk/kernel/	Rename INO to INR, for the sake of consistency with manuals.
1909	6418 d 17 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.
1896	6428 d 16 h	jermar	/trunk/	Convert sparc64 to detect keyboard and determine its physical address by walking the memory representation of the OpenFirmware device tree. Add bus-specific functions that know how to apply the "ranges" property to one component of the "reg" property. Buses supported so far include FHC, EBUS and PCI.
