3649 5670 d 21 h jermar /trunk/kernel/arch/sparc64/src/drivers/ More work on the psycho driver.  
3647 5670 d 22 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3646 5671 d 0 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5688 d 12 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
2510 6120 d 23 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.		  
2107 6334 d 22 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.		  
2089 6341 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6351 d 23 h jermar /trunk/ (c) versus (C)  
2067 6362 d 5 h jermar /trunk/kernel/ More formatting changes.  
2044 6386 d 1 h jermar /trunk/kernel/arch/sparc64/ On sparc64's tick interrupt, adjust the TICK_COMPARE register instead of the TICK
register. The TICK register now increments linearily and can be used by the get_cycle()
function.		  
1994 6408 d 6 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6408 d 7 h decky /trunk/ make framebuffer code more generic  
1986 6410 d 4 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6410 d 23 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1946 6441 d 21 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.		  
1921 6447 d 0 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6447 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 6447 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 6454 d 8 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1911 6454 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.
