44 tristate "LSI MPT Fusion SAS 3.0 & SAS 2.0 Device Driver"
45 depends on PCI && SCSI
50 This driver supports PCI-Express SAS 12Gb/s Host Adapters.
52 config SCSI_MPT2SAS_MAX_SGE
53 int "LSI MPT Fusion SAS 2.0 Max number of SG Entries (16 - 256)"
54 depends on PCI && SCSI && SCSI_MPT3SAS
58 This option allows you to specify the maximum number of scatter-
59 gather entries per I/O. The driver default is 128, which matches
60 MAX_PHYS_SEGMENTS in most kernels. However in SuSE kernels this
61 can be 256. However, it may decreased down to 16. Decreasing this
62 parameter will reduce memory requirements on a per controller instance.
64 config SCSI_MPT3SAS_MAX_SGE
65 int "LSI MPT Fusion SAS 3.0 Max number of SG Entries (16 - 256)"
66 depends on PCI && SCSI && SCSI_MPT3SAS
70 This option allows you to specify the maximum number of scatter-
71 gather entries per I/O. The driver default is 128, which matches
72 MAX_PHYS_SEGMENTS in most kernels. However in SuSE kernels this
73 can be 256. However, it may decreased down to 16. Decreasing this
74 parameter will reduce memory requirements on a per controller instance.
77 tristate "Legacy MPT2SAS config option"
