3790 5692 d 3 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 5705 d 22 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5707 d 1 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3714 5713 d 23 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3679 5724 d 14 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5725 d 19 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5731 d 19 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 5731 d 21 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 5732 d 16 h jermar /trunk/kernel/arch/sparc64/src/drivers/ More work on the psycho driver.  
3647 5732 d 18 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3646 5732 d 19 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5750 d 7 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
2510 6182 d 19 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 6396 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 6403 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6413 d 18 h jermar /trunk/ (c) versus (C)  
2067 6424 d 0 h jermar /trunk/kernel/ More formatting changes.  
2044 6447 d 21 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 6470 d 1 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6470 d 2 h decky /trunk/ make framebuffer code more generic  
1986 6471 d 23 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6472 d 19 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller
 
1946 6503 d 16 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 6508 d 19 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1920 6509 d 3 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 6509 d 18 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 6516 d 4 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1911 6516 d 16 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 6519 d 16 h jermar /trunk/kernel/ Rename INO to INR, for the sake of consistency with manuals.  
1909 6520 d 18 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 6527 d 2 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 6527 d 18 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 6530 d 2 h jermar /trunk/ Convert sparc64 framebuffer code to configure from the OpenFirmware device tree memory representation.  
1896 6530 d 17 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 6541 d 2 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.
 
1875 6545 d 19 h jermar /trunk/ sparc64 work.
- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors.
 
1849 6567 d 3 h jermar /trunk/kernel/ sparc64 work.
interrupt_vector trap experimental handling.
Minimal reverse-engineered FireHose Controller driver (documentation needed!).
Keyboard on Sun Enterprise is now interrupt driven. Keyboard on Sun Ultra
is still polled.
 
1844 6574 d 20 h jermar /trunk/kernel/ Add an option to compile the sparc64 kernel for Ultra 5 or Enterprise E6500.
Basic keyboard support (polling) based on ns16550 serial port (deployed on Ultra).
 
1842 6575 d 1 h jermar /trunk/kernel/ i8042 and z8530 separated, the tree compiles again.
Now there is some duplicated code in i8042.c and z8530.c,
but that can be eliminated in slower pace.
 
1841 6575 d 3 h jermar /trunk/kernel/ Start reorganization of different keyboard drivers.
What seemed like a screwed i8042 chip appears to be
Zilog 8530.

The repository won't compile now. To be fixed in next commits.
