44 tristate "LSI MPT Fusion SAS 2.0 Device Driver"
45 depends on PCI && SCSI
49 This driver supports PCI-Express SAS 6Gb/s Host Adapters.
51 config SCSI_MPT2SAS_MAX_SGE
52 int "LSI MPT Fusion Max number of SG Entries (16 - 128)"
53 depends on PCI && SCSI && SCSI_MPT2SAS
57 This option allows you to specify the maximum number of scatter-
58 gather entries per I/O. The driver default is 128, which matches
59 SAFE_PHYS_SEGMENTS. However, it may decreased down to 16.
60 Decreasing this parameter will reduce memory requirements
61 on a per controller instance.
63 config SCSI_MPT2SAS_LOGGING
64 bool "LSI MPT Fusion logging facility"
65 depends on PCI && SCSI && SCSI_MPT2SAS
67 This turns on a logging facility.
