4071 5589 d 15 h jermar /trunk/kernel/arch/sparc64/ Some additional fixes to the sgcn driver.  
4070 5589 d 17 h rimsky /trunk/ SGCN driver modified to reflect the new keyboard driver architecture. Making the Serengeti bootable image smaller by not including some servers/applications.  
3961 5606 d 19 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.		  
3880 5616 d 14 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3740 5665 d 18 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5666 d 20 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3672 5685 d 14 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5691 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.		  
3654 5691 d 16 h jermar /trunk/kernel/arch/sparc64/ After my effort yesterday, there are two rival psycho drivers.
Merge the two and remove the newer one.		  
3647 5692 d 13 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3577 5710 d 2 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
2510 6142 d 14 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.		  
2089 6362 d 21 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6373 d 14 h jermar /trunk/ (c) versus (C)  
1984 6432 d 14 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1921 6468 d 15 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1911 6476 d 12 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.		  
1910 6479 d 12 h jermar /trunk/kernel/ Rename INO to INR, for the sake of consistency with manuals.  
1909 6480 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.		  
1897 6489 d 21 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.
