CONFIG_SCSI_MPT3SAS_MAX_SGE: LSI MPT Fusion SAS 3.0 Max number of SG Entries (16 - 256)

General informations

The Linux kernel configuration item CONFIG_SCSI_MPT3SAS_MAX_SGE has multiple definitions:

LSI MPT Fusion SAS 3.0 Max number of SG Entries (16 - 256) found in drivers/scsi/mpt3sas/Kconfig

The configuration item CONFIG_SCSI_MPT3SAS_MAX_SGE:

• prompt: LSI MPT Fusion SAS 3.0 Max number of SG Entries (16 - 256)
• type: int
• depends on: CONFIG_PCI && CONFIG_SCSI && CONFIG_SCSI_MPT3SAS
• defined in drivers/scsi/mpt3sas/Kconfig
• found in Linux kernels: 4.4–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD

Help text

This option allows you to specify the maximum number of scatter- gather entries per I/O. The driver default is 128, which matches MAX_PHYS_SEGMENTS in most kernels. However in SuSE kernels this can be 256. However, it may decreased down to 16. Decreasing this parameter will reduce memory requirements on a per controller instance.
