4042 5631 d 2 h jermar /trunk/ Complete emancipation of kernel serial controller drivers (i8042, ns16550 and
z8530). Provide a common keyboard module for PC and Sun keyboards. The serial
line module is still to follow.		  
4026 5634 d 19 h jermar /trunk/ Make the kbd port drivers platform neutral by using PIO functions.
The kernel now supplies the physical address and the kernel virtual address.		  
4011 5635 d 21 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3982 5637 d 23 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3978 5638 d 22 h jermar /trunk/ Userspace driver for OBIO. This will make it possible to clear interrupts from
user space on UltraSPARC IIi and systems with Psycho. Not tested.		  
3969 5640 d 21 h jermar /trunk/ Add simple userspace FHC driver.
Modify the z8530 userspace driver
to send BUS_CLEAR_INTERRUPT
notification to the FHC driver.		  
3961 5644 d 3 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.		  
3941 5645 d 21 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3935 5646 d 18 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3908 5649 d 23 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5650 d 19 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 5665 d 0 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3844 5665 d 21 h decky /trunk/ silent kernel console output when user space console is active  
3790 5689 d 6 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 5703 d 2 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5704 d 4 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3714 5711 d 2 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3679 5721 d 18 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5722 d 22 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5728 d 22 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 5729 d 0 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 5729 d 19 h jermar /trunk/kernel/arch/sparc64/src/drivers/ More work on the psycho driver.  
3647 5729 d 21 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3646 5729 d 23 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5747 d 10 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
2510 6179 d 22 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 6393 d 21 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 6400 d 5 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6410 d 22 h jermar /trunk/ (c) versus (C)  
2067 6421 d 3 h jermar /trunk/kernel/ More formatting changes.  
2044 6445 d 0 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 6467 d 4 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6467 d 6 h decky /trunk/ make framebuffer code more generic  
1986 6469 d 2 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6469 d 22 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1946 6500 d 19 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 6505 d 23 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6506 d 7 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 6506 d 22 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 6513 d 7 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.
