   5 # The following commented-out examples of how to run blocktest for certain
   6 # driver and device pairs. The syntax of the calls is:
   7 #
   8 #   block_test <device> <parameters>
   9 #
  10 # <device> is the path to a device to run blocktest on. This may be a full
  11 # disk, a partition, or a subpartition. If possible, give blocktest the whole
  12 # disk; otherwise preferably the first partition with a size of slightly over
  13 # 8GB (for ATA) (better yet: slightly over 128GB); even fewer tests can be done
  14 # if you give it only a subpartition.
  15 #
  16 # <parameters> is a comma-separated list of parameters for blocktest. The
  17 # following parameters are supported and in fact expected:
  18 #
  19 # rw (or) ro   Specifying "rw" will let blocktest write to the target
  20 #              partition. This allows for a lot more tests, but keep in mind
  21 #              that any data on the partition (and, if the driver misbehaves,
  22 #              on other partitions and possibly other disks) WILL BE DESTROYED.
  23 #              Use "ro" for read-only mediums, such as CD-ROMs.
  24 # sector       Sector size, in bytes. This should be 512 for ATA devices, and
  25 #              2048 for ATAPI devices.
  26 # min_read     Minimum size of a read request. This must be at least 2 and at
  27 #              most the sector size, and the sector size must be divisible by
  28 #              it. A value other than the sector size allows blocktest to test
  29 #              sub-sector reads. Sub-sector writes are currently not supported
  30 #              by any driver and hence not by blocktest, so there is no
  31 #              matching "min_write" (yet).
  32 # element      Minimum size of a vector element within a larger I/O request.
  33 #              This must be at least 2 and at most min_read, and min_read must
  34 #              be divisible by this value. The idea is that several small
  35 #              elements may add up to the minimum read size.
  36 # max          Maximum size of any request. This should be a multiple of the
  37 #              sector size. Blocktest will not test what happens when this
  38 #              value is exceeded, but it will generate large requests up to
  39 #              this value. For drivers that do not have a maximum request size,
  40 #              simply use some large value (typically several megabytes).
  41 #
  42 # Before commenting out any entry, you MUST edit the device name for that
  43 # entry, or you WILL risk losing arbitrary data. You may run multiple tests in
  44 # parallel, on different devices. Note that at_wini has no maximum request
  45 # size, so an arbitray size is used. Finally, a disclaimer: a buggy device
  46 # driver may destroy any data it has access to, so use at your own risk.
