2071	6310 d 21 h	jermar	/trunk/	(c) versus (C)
1946	6400 d 18 h	jermar	/trunk/kernel/arch/sparc64/	sparc64 work. - Improve panic screen on data_access_exception by dumping contents of DSFSR and DSFAR. - Change the FHC enable interrupt code to only set the IMAP_V bit.
1910	6416 d 19 h	jermar	/trunk/kernel/	Rename INO to INR, for the sake of consistency with manuals.
1909	6417 d 20 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.
1875	6442 d 21 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.
1849	6464 d 6 h	jermar	/trunk/kernel/	sparc64 work. interrupt_vector trap experimental handling. Minimal reverse-engineered FireHose Controller driver (documentation needed!). Keyboard on Sun Enterprise is now interrupt driven. Keyboard on Sun Ultra is still polled.
