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 |

make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64 |

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 |

place for architectures with ia32 legacy I/O space. |

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 |

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. |

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. |
