| Eric Moore | 635374e | 2009-03-09 01:21:12 -0600 | [diff] [blame] | 48 | ---help--- |
| 49 | This driver supports PCI-Express SAS 6Gb/s Host Adapters. |

| 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. |

| 64 | bool "LSI MPT Fusion logging facility" |
| 65 | depends on PCI && SCSI && SCSI_MPT2SAS |

| 67 | This turns on a logging facility. |
