elanpexAMD Elan SC520 PCI Exception Instrumentation

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

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

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

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.

The elanpex device first appeared in NetBSD 5.0.

The elanpex driver was written by David Young <dyoung@NetBSD.org>.
