3959 5648 d 17 h jermar /trunk/kernel/genarch/src/kbd/ Remove unneeded stuff from kernel's ns16550 driver.  
3958 5648 d 17 h jermar /trunk/kernel/genarch/src/kbd/ Do not include the IPC stuff in the i8042 kernel driver.  
3947 5648 d 21 h jermar /trunk/ This is the evil commit. In particular, it does:

- introduces more powerful pseudo code for userspace IRQ top-half handlers
- changes the internals of IRQ dispatching
- simplifies the kernel's i8042 driver
- adapts the uspace i8042 driver to make use of the new pseudocode
- breaks all other architectures except ia32
- breaks almost all existing drivers
- breaks switching between uspace and kernel drivers		  
3941 5649 d 18 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3938 5649 d 22 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5650 d 15 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		  
3932 5650 d 16 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3931 5650 d 17 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		  
3928 5650 d 19 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3927 5650 d 19 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3906 5654 d 15 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.		  
3900 5655 d 1 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3877 5657 d 19 h decky /trunk/kernel/genarch/ remove (almost all) platform dependent code from drivers  
3714 5714 d 22 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3661 5731 d 17 h vana /trunk/ IA64: repair similators support  
3657 5732 d 2 h vana /trunk/ Legacy IRQ support, uspace NS16550 support, some minor changes  
3655 5732 d 18 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 5733 d 19 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3581 5750 d 16 h jermar /trunk/kernel/ Some cstyle.  
3577 5751 d 7 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver
