# 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.
#
# Since: 2.0
