C8
DMA Engine
Verifies the functionality of the DMA engine
block by performing numerous DMA read and
write operations to various system and
internal memory locations (and byte
boundaries) with varying lengths (from 1 byte
to over 4 KB, crossing the physical page
boundary) and different data patterns
(incremental, fixed, and random). CRC checks
are performed to ensure data integrity. The
DMA write test also verifies that DMA writes
do not corrupt the neighboring host memory.
C9
VPD
Exercises the Vital Product Data (VPD)
interface using PCI configuration cycles. You
must program a proper bootcode into the non-
volatile memory. If no VPD data is present
(that is, the VPD NVM area is all 0s), the test
first initializes the VPD data area with non-
zero data before starting the test and restores
the original data after the test completes.
C11
FIO Events
Verifies that the event bits in the CPU's Fast
IO (FIO) interface are triggering correctly
when a particular chip events occur, such as a
VPD request initiated by the host, an
expansion ROM request initiated by the host,
a timer event generated internally, toggling
any GPIO bits, or accessing NVM.
Group D: Ethernet Traffic Tests
D1
MAC Loopback
Enables MAC loopback mode in the adapter
and transmits 5000 Layer 2 packets of various
sizes. As the packets are received by
Broadcom NetXtreme II User Diagnostics,
they are checked for errors. Packets are
returned through the MAC receive path and
never reach the PHY. The adapter should not
be connected to a network.
