Changes to device_t struct to accomodate the upcoming PCI IRQ arbitration rewrite; Added device.c/h API to obtain name from the device_t struct; Significant changes to win/win_settings.c to clean up the code a bit and fix bugs; Ported all the CPU and AudioPCI commits from PCem; Added an API call to allow ACPI soft power off to gracefully stop the emulator; Removed the Siemens PCD-2L from the Dev branch because it now works; Removed the Socket 5 HP Vectra from the Dev branch because it now works; Fixed the Compaq Presario and the Micronics Spitfire; Give the IBM PC330 its own list of 486 CPU so it can have DX2's with CPUID 0x470; SMM fixes; Rewrote the SYSENTER, SYSEXIT, SYSCALL, and SYSRET instructions; Changed IDE reset period to match the specification, fixes #929; The keyboard input and output ports are now forced in front of the queue when read, fixes a number of bugs, including the AMI Apollo hanging on soft reset; Added the Intel AN430TX but Dev branched because it does not work; The network code no longer drops packets if the emulated network card has failed to receive them (eg. when the buffer is full); Changes to PCI card adding and renamed some PCI slot types, also added proper AGP bridge slot types; USB UHCI emulation is no longer a stub (still doesn't fully work, but at least Windows XP chk with Debug no longer ASSERT's on it); Fixed NVR on the the SMC FDC37C932QF and APM variants; A number of fixes to Intel 4x0 chipsets, including fixing every register of the 440LX and 440EX; Some ACPI changes.

/*An 'expected' exception is one that would be expected to occur on every execution
|
|
of this code path; eg a GPF due to being in v86 mode. An 'unexpected' exception is
|
|
one that would be unlikely to occur on the next exception, eg a page fault may be
|
|
fixed up by the exception handler and the next execution would not hit it.
|
|
|
|
This distinction is used by the dynarec; a block that hits an 'expected' exception
|
|
would be compiled, a block that hits an 'unexpected' exception would be rejected so
|
|
that we don't end up with an unnecessarily short block*/
