4042 5678 d 7 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.
 
3963 5691 d 7 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5691 d 8 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.
 
3960 5692 d 1 h jermar /trunk/kernel/genarch/include/kbd/ Remove extern declarations.  
3941 5693 d 2 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3938 5693 d 6 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5693 d 23 h jermar /trunk/kernel/ Improve the ns16550 driver.

- The driver support multiple instances.
- It still remembers the last registered IRQ in a global structure (cannot be
easily fixed now)
- Was converted to use PIO directly
 
3931 5694 d 1 h jermar /trunk/kernel/genarch/ Improve the i8042 kernel driver (phase I).

- Convert the code to be instance-aware
- Still using hardcoded initialization from legacy IO address
- Use elegant i8042 register map for PIO
 
3927 5694 d 4 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3907 5697 d 13 h decky /trunk/kernel/ remove forgotten #ifdef arch  
3906 5698 d 0 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.
 
3902 5698 d 8 h jermar /trunk/kernel/ Introduce a more platform-neutral name for programmed I/O.

The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers.
 
3704 5759 d 4 h decky /trunk/kernel/genarch/include/kbd/ add header  
3655 5776 d 3 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.
 
3646 5777 d 4 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5794 d 15 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
2089 6447 d 10 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6458 d 3 h jermar /trunk/ (c) versus (C)  
1957 6540 d 11 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6540 d 12 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1921 6553 d 4 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1920 6553 d 12 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 6554 d 2 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.
 
1896 6575 d 1 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.
 
1875 6590 d 3 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 6611 d 12 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 6619 d 5 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).
 
1843 6619 d 7 h jermar /trunk/kernel/genarch/ Move code duplicated in i8042.c and z8530.c to key.c.  
1842 6619 d 10 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 6619 d 11 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.
 
1838 6624 d 7 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1787 6648 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6676 d 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1474 6689 d 1 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
895 6782 d 3 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.
 
894 6782 d 6 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.
