4348 5671 d 1 h svoboda /branches/dynload/ Merge latest trunk changes to dynload.  
4347 5671 d 1 h svoboda /branches/dynload/ Merge trunk changes up to r4195 to dynload.  
4346 5672 d 12 h svoboda /branches/dynload/ Merge trunk changes up to r4145 to dynload.  
4114 5720 d 14 h jermar /trunk/ Fix one RAW dependency.  
4094 5720 d 16 h decky /trunk/kernel/genarch/ update for the new scheme of wiring device drivers to keyboard/serial modules  
4042 5725 d 18 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.		  
3960 5739 d 12 h jermar /trunk/kernel/genarch/include/kbd/ Remove extern declarations.  
3941 5740 d 13 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3938 5740 d 17 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5741 d 10 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		  
3907 5744 d 23 h decky /trunk/kernel/ remove forgotten #ifdef arch  
3906 5745 d 11 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 5745 d 18 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.		  
3655 5823 d 13 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 5824 d 14 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3577 5842 d 2 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
2089 6494 d 20 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6505 d 13 h jermar /trunk/ (c) versus (C)  
1921 6600 d 14 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6600 d 22 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.
