3502 5729 d 16 h rimsky /branches/sparc/ Implemented Serengeti console driver (only output, input TBD), all output now goes to the console instead of Simics CLI window.  
3477 5759 d 18 h rimsky /branches/sparc/kernel/arch/sparc64/ comments  
3467 5762 d 17 h rimsky /branches/sparc/ SMP and CPU initialiation modified to work even with Serengeti OFW tree layout; support for output to the Simics CLI console added (see my blog); some header files modified to conform US-III definition. Now HelenOS (on the sample configuration - usiii.simics) is able to run some userspace tasks.  
3343 5796 d 21 h decky /branches/sparc/ add sparc branch  
2510 6145 d 18 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 6359 d 17 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 6366 d 1 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6376 d 18 h jermar /trunk/ (c) versus (C)  
2067 6386 d 23 h jermar /trunk/kernel/ More formatting changes.  
2044 6410 d 20 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 6433 d 0 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6433 d 1 h decky /trunk/ make framebuffer code more generic  
1986 6434 d 22 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6435 d 18 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1946 6466 d 15 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 6471 d 19 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6472 d 2 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 6472 d 17 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 6479 d 3 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1911 6479 d 15 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.
