ifptest Subtests

Four subtests are run in online and functional modes:

• Mailbox Loopback test

Loads a series of registers into the input mailboxes on the card and then reads the output mailboxes and compares results. This verifies that the system side of the card is operating correctly, and that the internal data paths are okay.

• Firmware revision check

Reads the firmware revision from the firmware and compares it against a revision loaded by the driver.

• Checksum firmware test

Runs an internal checksum test on the installed firmware. This verifies that the RISC RAM on the card is fully functional and that the installed firmware is still intact. This test also serves as a quick RAM check of the RISC RAM.

• Dump revision levels

Extracts the hardware and firmware revision levels of different submodules on the card.
