This patch adds and uses #defines for PCI device classes and subclases,

This patch defines PCI vendor and device IDs in pci.h (matching those
from Linux's pci_ids.h), and uses those definitions where appropriate.

This version of the patch adds new option "werror" to -drive flag.
Possible values are:
report - report errors to a guest as IO errors
ignore - continue as if nothing happened
stop - stop VM on any error and retry last command on resume
enospc - stop vm on ENOSPC error and retry last command on resume
all other errors are reported to a guest.
Default is "report" to maintain current behaviour.

During hardware detection Openserver issues commands to slaves on both primary
and secondary ports. We already return a zero for the status register in this
situation but after reading the status register the Openserver installer
proceeds to check the value of the error register. Currently we return the
existing value in the register. This confuses the installer and it tries to
access the slave units later on. When the command that gets issued later gets
ignored the installer freezes. The patch below returns zero when reading the
error register if a slave unit is selected. Openserver can now successfully be
installed using the emulated IDE hard drive.

This patch adds emulation for a CompactFlash on sh4/r2d board.
The device is CF, but wired to be worked as True-IDE mode, and connected
directly to SH bus. So, this code is to support generally mmio based
IDEs which are supported by "pata_platform" driver in linux kernel.

This patch tweaks the ATAPI CDROM emulation to fix an annoyance seen
when running a variety of Linux guests: the desktop GUI shows a CDROM
device as present, but is unable to automount the media and display its
contents.
The patch adds the PLAY_AUDIO capability bit to the data returned by
MODE_SENSE commands. That convinces the guest kernel to determine what
kind of media is present.
Arguably Linux could be smarter about this, but it's my guess there are
few (if any) hardware CDROM drives that don't set the bit, and there are
a large number of Linux distros that exhibit this problem.

The DIAGNOSE command in the qemu IDE implementation has an error when
use dfor packet devices.
The status register value is dependant on the drive being a packet
device or not, this patch corrects the returned status.
From the ATA/PI specification (V6 draft):
"If the device implements the PACKET command feature set, the device
SHALL clear bits 6,5,4,3,2 and 0 in the Status register to zero."
A selection of physical devices have been checked and do conform to
the specifications behaviour.

The current implementation of GET_CONFIGURATION in the ATAPI stack of qemu
replies a different length depending on the buffer, the data should be

On the other hand the SCSI spec defines that length information has to be
