The test is located in test/blocktest. It requires hand-editing of its configuration, and is not part of any automated test set.

# The blocktest driver expects the following parameters:
|
|
#
|
|
# device Path to the device node to perform the test on. This may be a
|
|
# full disk, a partition, or a subpartition. If possible, give
|
|
# blocktest the whole disk; otherwise preferably the first
|
|
# partition with a size of slightly over 8GB (for ATA) (better
|
|
# yet: slightly over 128GB); even fewer tests can be done if you
|
|
# give it only a subpartition.
|
|
# rw (or) ro Specifying "rw" will let blocktest write to the target
|
|
# partition. This allows for a lot more tests, but keep in mind
|
|
# that any data on the partition (and, if the driver misbehaves,
|
|
# on other partitions and possibly other disks) WILL BE DESTROYED.
|
|
# Use "ro" for read-only mediums, such as CD-ROMs.
|
|
# sector Sector size, in bytes. This should be 512 for ATA devices, and
|
|
# 2048 for ATAPI devices.
|
|
# min_read Minimum size of a read request. This must be at least 2 and at
|
|
# most the sector size, and the sector size must be divisible by
|
|
# it. A value other than the sector size allows blocktest to test
|
|
# sub-sector reads. Sub-sector writes are currently not supported
|
|
# by any driver and hence not by blocktest, so there is no
|
|
# matching "min_write" (yet).
|
|
# element Minimum size of a vector element within a larger I/O request.
|
|
# This must be at least 2 and at most min_read, and min_read must
|
|
# be divisible by this value. The idea is that several small
|
|
# elements may add up to the minimum read size.
|
|
# max Maximum size of any request. This should be a multiple of the
|
|
# sector size. Blocktest will not test what happens when this
|
|
# value is exceeded, but it will generate large requests up to
|
|
# this value. For drivers that do not have a maximum request size,
|
|
# simply use some large value (typically several megabytes).
|
|
|
|
# The following are examples of how to configure blocktest for certain driver
|
|
# and device pairs. Before commenting out any entry, you MUST edit the "device"
|
|
# option for that entry, or you WILL risk losing arbitrary data. You may run
|
|
# multiple tests in parallel (on different devices), but you will then have to
|
|
# give them different labels. Note that at_wini has no maximum request size, so
|
|
# an arbitray size is used. Finally, a disclaimer: a buggy device driver may
|
|
# destroy any data it has access to, so use at your own risk.
