# @ErrorClass
#
# QEMU error classes
#
# @GenericError: this is used for errors that don't require a specific error
# class. This should be the default case for most errors
#
# @CommandNotFound: the requested command has not been found
#
# @DeviceEncrypted: the requested operation can't be fulfilled because the
# selected device is encrypted
#
# @DeviceNotActive: a device has failed to be become active
#
# @DeviceNotFound: the requested device has not been found
#
# @KVMMissingCap: the requested operation can't be fulfilled because a
# required KVM capability is missing
#
# Since: 1.2

# LostTickPolicy:
#
# Policy for handling lost ticks in timer devices.
#
# @discard: throw away the missed tick(s) and continue with future injection
# normally. Guest time may be delayed, unless the OS has explicit
# handling of lost ticks
#
# @delay: continue to deliver ticks at the normal rate. Guest time will be
# delayed due to the late tick
#
# @merge: merge the missed tick(s) into one tick and inject. Guest time
# may be delayed, depending on how the OS reacts to the merging
# of ticks
#
# @slew: deliver ticks at a higher rate to catch up with the missed tick. The
# guest time should not be delayed once catchup is complete.
#
# Since: 2.0

# BiosAtaTranslation:
#
# Policy that BIOS should use to interpret cylinder/head/sector
# addresses. Note that Bochs BIOS and SeaBIOS will not actually
# translate logical CHS to physical; instead, they will use logical
# block addressing.
#
# @auto: If cylinder/heads/sizes are passed, choose between none and LBA
# depending on the size of the disk. If they are not passed,
# choose none if QEMU can guess that the disk had 16 or fewer
# heads, large if QEMU can guess that the disk had 131072 or
# fewer tracks across all heads (i.e. cylinders*heads<131072),
# otherwise LBA.
#
# @none: The physical disk geometry is equal to the logical geometry.
#
# @lba: Assume 63 sectors per track and one of 16, 32, 64, 128 or 255
# heads (if fewer than 255 are enough to cover the whole disk
# with 1024 cylinders/head). The number of cylinders/head is
# then computed based on the number of sectors and heads.
#
# @large: The number of cylinders per head is scaled down to 1024
# by correspondingly scaling up the number of heads.
#
# @rechs: Same as @large, but first convert a 16-head geometry to
# 15-head, by proportionally scaling up the number of
# cylinders/head.

# @dump-guest-memory
#
# Dump guest's memory to vmcore. It is a synchronous operation that can take
# very long depending on the amount of guest memory. This command is only
# supported on i386 and x86_64.
#
# @paging: if true, do paging to get guest's memory mapping. This allows
# using gdb to process the core file.
#
# IMPORTANT: this option can make QEMU allocate several gigabytes
# of RAM. This can happen for a large guest, or a
# malicious guest pretending to be large.
#
# Also, paging=true has the following limitations:
#
# 1. The guest may be in a catastrophic state or can have corrupted
# memory, which cannot be trusted
# 2. The guest can be in real-mode even if paging is enabled. For
# example, the guest uses ACPI to sleep, and ACPI sleep state
# goes in real-mode
#
# @protocol: the filename or file descriptor of the vmcore. The supported
# protocols are:
#
# 1. file: the protocol starts with "file:", and the following
# string is the file's path.
# 2. fd: the protocol starts with "fd:", and the following string
# is the fd's name.
#
# @begin: #optional if specified, the starting physical address.
#
# @length: #optional if specified, the memory size, in bytes. If you don't
# want to dump all guest's memory, please specify the start @begin
# and @length
#
# @format: #optional if specified, the format of guest memory dump. But non-elf
# format is conflict with paging and filter, ie. @paging, @begin and
# @length is not allowed to be specified with non-elf @format at the
# same time (since 2.0)

# Returns: nothing on success

# Since: 1.2
