Currently, both NVME and SCSI get their IO buffers from separate pools. XRI's are associated 1:1 with IO buffers, so XRI's are also split between protocols. Eliminate the independent pools and use a single pool. Each buffer structure now has a common section and a protocol section. Per protocol routines for SGL initialization are removed and replaced by common routines. Initialization of the buffers is only done on the common area. All other fields, which are protocol specific, are initialized when the buffer is allocated for use in the per-protocol allocation routine. In the past, the SCSI side allocated IO buffers as part of slave_alloc calls until the maximum XRIs for SCSI was reached. As all XRIs are now common and may be used for either protocol, allocation for everything is done as part of adapter initialization and the scsi side has no action in slave alloc. As XRI's are no longer split, the lpfc_xri_split module parameter is removed. Adapters based on SLI3 will continue to use the older scsi_buf_list_get/put routines. All SLI4 adapters utilize the new IO buffer scheme Signed-off-by: Dick Kennedy <dick.kennedy@xxxxxxxxxxxx> Signed-off-by: James Smart <jsmart2021@xxxxxxxxx> --- drivers/scsi/lpfc/lpfc.h | 17 +- drivers/scsi/lpfc/lpfc_attr.c | 23 +- drivers/scsi/lpfc/lpfc_crtn.h | 6 +- drivers/scsi/lpfc/lpfc_init.c | 515 +++++++++++++++++++++++------------------- drivers/scsi/lpfc/lpfc_nvme.c | 500 ++++++---------------------------------- drivers/scsi/lpfc/lpfc_nvme.h | 33 +-- drivers/scsi/lpfc/lpfc_scsi.c | 500 +++++++++------------------------------- drivers/scsi/lpfc/lpfc_scsi.h | 27 +-- drivers/scsi/lpfc/lpfc_sli.c | 279 +++++++++++++++++------ drivers/scsi/lpfc/lpfc_sli4.h | 16 +- 10 files changed, 707 insertions(+), 1209 deletions(-) Reviewed-by: Hannes Reinecke <hare@xxxxxxxx>
