Subtest Name Description
1200 Symbios PCI
configuration space test
Verifies the ability of the
SAGA to access the Symbios
SCSI controller by way of the
PCI configuration space.
Verifies the PCI vendor ID and
device ID fields to be 0x1000
and 0x000f, respectively. Also
verifies the base address
registers to be writable and
readable.
1205 Symbios SCSI PCI I/O
and Memory space test
Maps the Symbios SCSI
controller through PCI
configuration space so that the
controller’s CSRs may be
accessed by way of both PCI I/
O and memory space. The test
writes a pattern to a scratch
register (SCRATCHA) in the
Symbios chip. The register is
then read back to verify the
previous write succeeded.
