# NAME

`elanpex` —
AMD Elan SC520 PCI Exception Instrumentation

# SYNOPSIS

`elansc* at mainbus? bus ?`
`elanpex* at elansc?`

# DESCRIPTION

The `elanpex` driver supports the PCI exception-reporting facilities of the AMD Elan SC520 microcontroller's integrated PCI host controller.

# DIAGNOSTICS

PCI master exceptions

  The host controller may originate a transaction of type %s on bus address %x that fails for the following reasons:

  elanpex0: %s %x master retry timeout
  elanpex0: %s %x master target abort
  elanpex0: %s %x master abort
  elanpex0: %s %x master system error
  elanpex0: %s %x master received parity error
  elanpex0: %s %x master detected parity error

  Transaction types include

  i/o read
  i/o write
  memory rd
  memory wr
  cfg rd
  cfg wr
PCI target exceptions

  The host controller may be the target of a failed transaction of type %s at bus address %x. Failures may occur for the following reasons:

  elanpex0: %s %x target delayed txn timeout
  elanpex0: %s %x target address parity
  elanpex0: %s %x target data parity

  Transaction types are alike to failed master exceptions.
