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. 62 63config SCSI_MPT3SAS_MAX_SGE 64 int "LSI MPT Fusion SAS 3.0 Max number of SG Entries (16 - 256)" 65 depends on PCI && SCSI && SCSI_MPT3SAS 66 default "128" 67 range 16 256 68 ---help--- 69 This option allows you to specify the maximum number of scatter- 70 gather entries per I/O.
