Currently, both nvme and fcp each have their own concept of an io_channel, which is a combination wq/cq and associated msix. Different cpus would share an io_channel. The driver is now moving to per-cpu wq/cq pairs and msix vectors. The driver will still use separate wq/cq pairs per protocol on each cpu, but the protocols will share the msix vector. Given the elimination of the nvme and fcp io channels, the module parameters will be removed. A new parameter, lpfc_hdw_queue is added which allows the wq/cq pair allocation per cpu to be overridden and allocated to lesser value. If lpfc_hdw_queue is zero, the number of pairs allocated will be based on the number of cpus. If non-zero, the parameter specifies the number of queues to allocate. At this time, the maximum non-zero value is 64. To manage this new paradigm, a new hardware queue structure is created to track queue activity and relationships. As MSIX vector allocation must be known before setting up the relationships, msix allocation now occurs before queue datastructures are allocated. If the number of vectors allocated is less than the desired hardware queues, the hardware queue counts will be reduced to the number of vectors Signed-off-by:

There is a extra queue and msix vector for expresslane. Now that the driver will be doing queues per cpu, this oddball queue is no longer needed. Expresslane will utilize the normal per-cpu queues. Updated debugfs sli4 queue output to go along with the change Signed-off-by:

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:

lpfc_nvme_prep_io_cmd() checks for null pnode, but caller lpfc_nvme_fcp_io_submit() has already ensured it's non-null. Remove the pnode null check. Signed-off-by:

An hba-wide lock is taken in the nvme io completion routine. The lock covers null'ing of the nrport pointer in the cmd structure. The nrport member isn't necessary. After extracting the pointer from the command, the pointer was dereferenced to get the fc discovery node pointer. But the fc discovery node pointer is alrady in the command structure so the dereferrence was unnecessary. Eliminated the nrport structure member and its use, which also eliminates the port-wide lock.

When loop was made down explicitly due to cable pull, then for N2N toplogy, if FAWWPN BIT is enabled by user, then it would restore some default (garbage) value for Physical port WWPN, so this show garbage WWPN for the port. Fix is, to restore physical port WWPN, if it is fabric configuration. When loop is explicitly made down, and FAWWPN feature is enabled, then driver need to restore original flashed WWPN.

This patch provide call back functions to stop the chip and resume the chip if the PCI lower level driver wants to perform function level reset/FLR. Before the FLR, the chip will be stopped to turn off all DMA activity. After the FLR, the chip is reset to resume previous operation state. Signed-off-by:

This patch adds support for the new DEVICE_LIST DCMD. Driver currently sends two separate DCMDs for getting the list of PDs and LDs that are exposed to host. The new DCMD provides a single interface to get a list of both PDs and LDs that are exposed to the host. Based on the list of target IDs that are returned by this DCMD, driver will add the devices (PD/LD) to SML. Driver will check for FW support for this new DCMD and based on the support will either send the new DCMD or will fall back to the earlier method of sending two separate DCMDs for PD and LD list.
