3790	5589 d 23 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 14 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	6300 d 21 h	decky	/trunk/	huge type system cleanup remove cyclical type dependencies across multiple header files many minor coding style fixes
2071	6311 d 14 h	jermar	/trunk/	(c) versus (C)
1946	6401 d 12 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	6417 d 12 h	jermar	/trunk/kernel/	Rename INO to INR, for the sake of consistency with manuals.
1909	6418 d 14 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	6443 d 15 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 23 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.
