ioport: use INT64_MAX for IO ranges

Expression UINT64_MAX + 1 will make the range bigger than
what can be represented with a 64 bit type. This would
trigger an assert in int128_get64() after the next patch.

ioport: add destructor method to IORange

Previously all callers had a containing object with a destructor that
could be used to trigger cleanup of the IORange objects (typically
just freeing the containing object), but a forthcoming memory API
change doesn't fit this pattern. Rather than setting up a new global...

ioport: change portio_list not to use memory_region_set_offset()

memory_region_set_offset() will be going away soon, so don't use it.
Use an alias instead.

Introduce PortioList

Add a type and methods for manipulating a list of disjoint I/O ports,
used in some older hardware devices.

ioport: register ranges by byte aligned addresses always

The I/O port space is byte addressable, even for word and long accesses.

An example is the VMware svga card, which has long ports on offsets 0,
1, and 2.

report serial devices created with -device in the PIIX4 config space

Serial and parallel devices created with -device are not reported in
the PIIX4 configuration space, and are hence not picked up by the DSDT.
This upsets Windows, which hides them altogether from the guest....

ioport: Improve error output

Type-safe ioport callbacks

The current ioport callbacks are not type-safe, in that they accept an "opaque"
pointer as an argument whose type must match the argument to the registration
function; this is not checked by the compiler.

This patch adds an alternative that is type-safe. Instead of an opaque...

Revert "Get rid of _t suffix"

In the very least, a change like this requires discussion on the list.

The naming convention is goofy and it causes a massive merge problem. Something
like this must be presented on the list first so people can provide input...

ioports: remove unused env parameter and compile only once

The CPU state parameter is not used, remove it and adjust callers. Now we

Unbreak large mem support by removing kqemu

kqemu introduces a number of restrictions on the i386 target. The worst is that
it prevents large memory from working in the default build.

Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on...

ioport: use uint{32, 16, 8}_t for ioport value and pio_addr_t for ioport address.

Using int for cpu_{in, out}[bwl] is inconsistent with other part
because for address or value, uintN_t is used by other qemu part.
