4011	5724 d 23 h	svoboda	/trunk/kernel/	String functions should be declared in string.h (and implemented in string.c) in the kernel.
3982	5727 d 1 h	jermar	/trunk/kernel/	Do not set sysinfo for uspace drivers directly in the kernel drivers.
3978	5727 d 23 h	jermar	/trunk/	Userspace driver for OBIO. This will make it possible to clear interrupts from user space on UltraSPARC IIi and systems with Psycho. Not tested.
3969	5729 d 22 h	jermar	/trunk/	Add simple userspace FHC driver. Modify the z8530 userspace driver to send BUS_CLEAR_INTERRUPT notification to the FHC driver.
3961	5733 d 5 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.
3935	5735 d 20 h	jermar	/trunk/kernel/arch/sparc64/src/drivers/	Fix sparc64 build.
3790	5778 d 8 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.
3714	5800 d 4 h	decky	/trunk/kernel/	do not waist resources if no keyboard driver is used
3655	5818 d 0 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.
3646	5819 d 0 h	jermar	/trunk/kernel/	Initial support for interrupt driven driver for ns16550.
3577	5836 d 12 h	vana	/trunk/kernel/	Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver
2089	6489 d 7 h	decky	/trunk/	huge type system cleanup remove cyclical type dependencies across multiple header files many minor coding style fixes
2071	6499 d 23 h	jermar	/trunk/	(c) versus (C)
1921	6595 d 0 h	jermar	/trunk/kernel/	Changes in ns16550 and z8530 drivers. Add some stuff for IRQ notifications to irq_t.
1920	6595 d 8 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	6595 d 23 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.
1912	6602 d 9 h	jermar	/trunk/kernel/	Separate mapping of EBUS interrupts into two parts: EBUS and PCI.
1911	6602 d 21 h	jermar	/trunk/kernel/	Add support for interrupt mapping in the Sabre PCI controller. Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree. Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt. I suspect something needs to be enabled in the EBUS registers.
1909	6606 d 23 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	6616 d 22 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.
