33 # LostTickPolicy:
34 #
35 # Policy for handling lost ticks in timer devices.
36 #
37 # @discard: throw away the missed tick(s) and continue with future injection
38 # normally. Guest time may be delayed, unless the OS has explicit
39 # handling of lost ticks
40 #
41 # @delay: continue to deliver ticks at the normal rate. Guest time will be
42 # delayed due to the late tick
43 #
44 # @merge: merge the missed tick(s) into one tick and inject. Guest time
45 # may be delayed, depending on how the OS reacts to the merging
46 # of ticks
47 #
48 # @slew: deliver ticks at a higher rate to catch up with the missed tick. The
49 # guest time should not be delayed once catchup is complete.

60 # addresses. Note that Bochs BIOS and SeaBIOS will not actually
61 # translate logical CHS to physical; instead, they will use logical
62 # block addressing.
63 #
64 # @auto: If cylinder/heads/sizes are passed, choose between none and LBA
65 # depending on the size of the disk. If they are not passed,
66 # choose none if QEMU can guess that the disk had 16 or fewer
67 # heads, large if QEMU can guess that the disk had 131072 or
68 # fewer tracks across all heads (i.e. cylinders*heads<131072),
69 # otherwise LBA.
70 #
71 # @none: The physical disk geometry is equal to the logical geometry.
72 #
73 # @lba: Assume 63 sectors per track and one of 16, 32, 64, 128 or 255
74 # heads (if fewer than 255 are enough to cover the whole disk
75 # with 1024 cylinders/head). The number of cylinders/head is
76 # then computed based on the number of sectors and heads.
77 #
78 # @large: The number of cylinders per head is scaled down to 1024
79 # by correspondingly scaling up the number of heads.
80 #
81 # @rechs: Same as @large, but first convert a 16-head geometry to
82 # 15-head, by proportionally scaling up the number of
83 # cylinders/head.
