3935 5658 d 4 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3908 5661 d 9 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5662 d 5 h jermar /trunk/kernel/ IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument.
 
3852 5676 d 10 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3844 5677 d 6 h decky /trunk/ silent kernel console output when user space console is active  
3790 5700 d 16 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.  
3740 5714 d 11 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5715 d 14 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3714 5722 d 12 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3679 5733 d 3 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5734 d 8 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5740 d 8 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 5740 d 10 h jermar /trunk/kernel/arch/sparc64/ After my effort yesterday, there are two rival psycho drivers.
Merge the two and remove the newer one.
 
3649 5741 d 5 h jermar /trunk/kernel/arch/sparc64/src/drivers/ More work on the psycho driver.  
3647 5741 d 7 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3646 5741 d 8 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5758 d 20 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
2510 6191 d 8 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 6405 d 7 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 6411 d 15 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6422 d 7 h jermar /trunk/ (c) versus (C)  
2067 6432 d 13 h jermar /trunk/kernel/ More formatting changes.  
2044 6456 d 10 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 6478 d 14 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6478 d 15 h decky /trunk/ make framebuffer code more generic  
1986 6480 d 12 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6481 d 8 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller
 
1946 6512 d 5 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 6517 d 8 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1920 6517 d 16 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 6518 d 7 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 6524 d 17 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1911 6525 d 5 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 6528 d 5 h jermar /trunk/kernel/ Rename INO to INR, for the sake of consistency with manuals.  
1909 6529 d 7 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.
 
1899 6535 d 15 h jermar /trunk/ sparc64 work:
- Loader now starts all processors.
- Kernel halts all but the bootstrup processor for now.
- Read clock-frequency from the respective processor node in the device tree
 
1898 6536 d 7 h jermar /trunk/kernel/ Support for FFB (Creator 3D) framebuffer detection on sparc64.
(Not tested as the Ultra 60, which I have for testing, and which
only has this type of framebuffer doesn't boot for some unknown reason.)
 
1897 6538 d 15 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6539 d 6 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.
 
1881 6549 d 15 h jermar /trunk/ sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places

OpenFirmware work:
- two new functions for walking the device tree

Generic boot loader work:
- added basic string functions

Usual pile of indentation and formatting fixes.
