Description:
This is the smallest unit a physical storage device can
write atomically. It is usually the same as the logical
block size but may be bigger. One example is SATA
drives with 4KB sectors that expose a 512-byte logical
block size to the operating system. For stacked block
devices the physical_block_size variable contains the
maximum physical_block_size of the component devices.

penalty. For disk drives this is often the physical

4. Software error injection

Debugging PCIE AER error recovery code is quite difficult because it
is hard to trigger real hardware errors. Software based error
injection can be used to fake various kinds of PCIE errors.

First you should enable PCIE AER software error injection in kernel
configuration, that is, following item should be in your .config.

CONFIG_PCIEAER_INJECT=y or CONFIG_PCIEAER_INJECT=m

After reboot with new kernel or insert the module, a device file named
/dev/aer_inject should be created.

Then, you need a user space tool named aer-inject, which can be gotten
from:
http://www.kernel.org/pub/linux/utils/pci/aer-inject/

More information about aer-inject can be found in the document comes
with its source code.
