| 45 | depends on PCI && SCSI |
| 46 | select SCSI_SAS_ATTRS |
| 47 | select RAID_ATTRS |
| 48 | ---help--- |
| 49 | This driver supports PCI-Express SAS 12Gb/s Host Adapters. |

| 51 | config SCSI_MPT3SAS_MAX_SGE |
| 52 | int "LSI MPT Fusion Max number of SG Entries (16 - 256)" |
| 53 | depends on PCI && SCSI && SCSI_MPT3SAS |
| 54 | default "128" |
| 55 | range 16 256 |
| 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 | MAX_PHYS_SEGMENTS in most kernels. However in SuSE kernels this |
| 60 | can be 256. However, it may decreased down to 16. Decreasing this |
| 61 | parameter will reduce memory requirements on a per controller instance. |

| 64 | bool "LSI MPT Fusion logging facility" |
| 65 | depends on PCI && SCSI && SCSI_MPT3SAS |
| 66 | ---help--- |
| 67 | This turns on a logging facility. |
