43config SCSI_MPT2SAS
44 tristate "LSI MPT Fusion SAS 2.0 Device Driver"
45 depends on PCI && SCSI
46 select SCSI_SAS_ATTRS
47 ---help---
48 This driver supports PCI-Express SAS 6Gb/s Host Adapters.
49
50config SCSI_MPT2SAS_MAX_SGE
51 int "LSI MPT Fusion Max number of SG Entries (16 - 128)"
52 depends on PCI && SCSI && SCSI_MPT2SAS
53 default "128"
54 range 16 128
55 ---help---
56 This option allows you to specify the maximum number of scatter-
57 gather entries per I/O. The driver default is 128, which matches
58 SAFE_PHYS_SEGMENTS. However, it may decreased down to 16.
59 Decreasing this parameter will reduce memory requirements
60 on a per controller instance.
61
62config SCSI_MPT2SAS_LOGGING
63 bool "LSI MPT Fusion logging facility"
64 depends on PCI && SCSI && SCSI_MPT2SAS
65 ---help---
66 This turns on a logging facility.
