4691 5606 d 22 h svoboda /branches/dynload/ Merge trunk changes up to r4686.  
4348 5717 d 7 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
4346 5718 d 18 h svoboda /branches/dynload/ Merge trunk changes up to r4145 to dynload.  
4092 5766 d 22 h decky /trunk/kernel/genarch/ wire keyboard/serial module and device drivers in a more obvious way
(first a device driver is initialized and then it is connected to the generic module)
 
4042 5772 d 0 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 5785 d 0 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5785 d 1 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 5785 d 18 h jermar /trunk/kernel/genarch/include/kbd/ Remove extern declarations.  
3941 5786 d 19 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3938 5786 d 23 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5787 d 16 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 5787 d 18 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 5787 d 21 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3907 5791 d 6 h decky /trunk/kernel/ remove forgotten #ifdef arch  
3906 5791 d 17 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 5792 d 1 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 5852 d 21 h decky /trunk/kernel/genarch/include/kbd/ add header  
3655 5869 d 20 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 5870 d 21 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5888 d 8 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver
