43config SCSI_MPT2SAS
44	tristate "LSI MPT Fusion SAS 2.0 Device Driver"
45	depends on PCI && SCSI
46	select SCSI_SAS_ATTRS
47	select RAID_ATTRS
48	---help---
49	This driver supports PCI-Express SAS 6Gb/s Host Adapters.

51config SCSI_MPT2SAS_MAX_SGE
52	int "LSI MPT Fusion Max number of SG Entries (16 - 128)"
53	depends on PCI && SCSI && SCSI_MPT2SAS
54	default "128"
55	range 16 128
56	---help---
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.

63config SCSI_MPT2SAS_LOGGING
64	bool "LSI MPT Fusion logging facility"
65	depends on PCI && SCSI && SCSI_MPT2SAS
66	---help---
67	This turns on a logging facility.
