| * | | [SCSI] be2iscsi: Fix displaying the FW Version from driver.Jayamohan Kallickal2013-05-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mgmt_hba_attributes structure declared was not proper and because of that the FW response returned for the MBX_CMD was not matching. This issue went unnoticed as mgmt_hba_attribs structure members were never used in the code path. This fix of displaying the FW version had to change the mgmt_hba_attrib structure also. The latest driver will also work with the older FW as the issue was in the driver declaration.

One of the goals of FC-BB-5 was to be as nonintrusive as possible on initiators and targets, and therefore FIP VLAN discovery occurs in the native VLAN used by the initiator or target to exchange Ethernet traffic. The FIP VLAN discovery protocol is the only FIP protocol running on the native VLAN; all other FIP protocols run on the discovered FCoE VLANs. If an administrator has manually configured FCoE VLANs on ENodes and FCFs, there is no need to use this protocol. FIP and FCoE will run over the configured VLANs. An ENode without FCoE VLANs configuration would use this automated discovery protocol to discover over which VLANs FCoE is running. The ENode sends a FIP VLAN discovery request to a multicast MAC address called All-FCF-MACs, which is a multicast MAC address to which all FCFs listen. All FCFs that can be reached in the native VLAN of the ENode are expected to respond on the same VLAN with a response that lists one or more FCoE VLANs that are available for the ENode's VN_Port login. This protocol has the sole purpose of allowing the ENode to discover all the available FCoE VLANs. Now the ENode may enable a subset of these VLANs for FCoE Running the FIP protocol in these VLANs on a per VLAN basis. And FCoE data transactions also would occur on this VLAN. Hence, Except for FIP VLAN discovery, all other FIP and FCoE traffic runs on the selected FCoE VLAN. Its only the FIP VLAN Discovery protocol that is permitted to run on the Default native VLAN of the system. [**** NOTE ****] We are working on moving this feature definitions and functionality to libfcoe module. We need this patch to be approved, as Suse is looking forward to merge this feature in SLES 11 SP3 release. Once this patch is approved, we will submit patch which should move vlan discovery feature to libfoce.

When a target is sent multiple requests, we always drive them to the same queue so that FIFO processing order is kept. However, if a target was idle, we can choose a queue arbitrarily. In this case the queue is chosen according to the current VCPU, so the driver expects the number of request queues to be equal to the number of VCPUs. This makes it easy and fast to select the queue, and also lets the driver optimize the IRQ affinity for the virtqueues (each virtqueue's affinity is set to the CPU that "owns" the queue). The speedup comes from improving cache locality and giving CPU affinity to the virtqueues, which is why this scheme was selected. Assuming that the thread that is sending requests to the device is I/O-bound, it is likely to be sleeping at the time the ISR is executed, and thus executing the ISR on the same processor that sent the requests is cheap. However, the kernel will not execute the ISR on the "best" processor unless you explicitly set the affinity. This is because in practice you will have many such I/O-bound processes and thus many otherwise idle processors. Then the kernel will execute the ISR on a random processor, rather than the one that is sending requests to the device. The alternative to per-CPU virtqueues is per-target virtqueues. To achieve the same locality, we could dynamically choose the virtqueue's affinity based on the CPU of the last task that sent a request. This is less appealing because we do not set the affinity directly---we only provide a hint to the irqbalanced running in userspace. Dynamically changing the affinity only works if the userspace applies the hint fast enough.

We will find new uses for it in the next few patches, so this patch does not drop it completely. And as James suggested, we use entries target_alloc and target_destroy in the host template to allocate and destroy the virtio_scsi_target_state of each target, attach this struct to scsi_target->hostdata. Now we can get at it from the sdev with scsi_target(sdev)->hostdata. No messing around with fixed size arrays and bulk memory allocation and no need to pass in the maximum target size as a parameter because everything should now happen dynamically.

| * | | | proc: Supply an accessor for getting the data from a PDE's parentDavid Howells2013-05-01

ReiserFS, for instance, stores the super_block pointer in the proc directory it makes for that super_block, and a pointer to the respective seq_file show function in each of the proc files in that directory. This allows a reduction in the number of file_operations structs, open functions and seq_operations structs required. The problem otherwise is that each show function requires two pieces of data but only has storage for one per PDE (and this has no release function).
