The VF driver will send an 'init' request as part of its nic load flow. This message is used by the VF to publish the GPA's of its status blocks, slow path ring and statistics buffer. The PF driver notes all this down in the VF database, and also uses this message to transfer the VF to VF_INIT state internally. Signed-off-by:

At nic load of the PF, if VFs may be present, prepare the device for the VFs. Initialize the VF database in preparation of VF arrival. Signed-off-by:

When A PF determines that it may have to manage SRIOV VFs it allocates a database for this purpose. The database is intended to keep track of the VF state, the resources allocated for each VF (queues, interrupt vectors, etc), the state of the VF's queues. When the VF loads the database is updated accordingly. When A VF closes the database is consulted to determine which resources need to be released (close queues against device, reclaim interrupt vectors, etc). Signed-off-by:

Generally, the VF driver cannot access the chip, except by the narrow window its BAR allows. Care had to be taken so the VF driver will not reach code which accesses the chip elsewhere. Refactor the nic_load flow into parts so it would be easier to separate the VF-only logic from the PF-only logic. Signed-off-by:

Add the 'acquire' request to VF <-> PF channel and use it at VF probe. In the acquire request the VF driver lists the resources it would like to have. In the response the PF either ratifies the request, or denies it and supplies the maximum values supported. The VF may then attempt another acquire request. This patch adds the bnx2x_vfpf.c file which contains the implementation of the VF to PF hardware channel. Signed-off-by:

To support probing and removing of a bnx2x virtual function the following were added: 1. add bnx2x_vfpf.h: defines the VF to PF channel 2. add bnx2x_sriov.h: header for bnx2x SR-IOV functionality 3. enumerate VF hw types (identify VFs) 4. if driving a VF, map VF bar 5. if driving a VF, allocate Vf to PF channel 6. refactor interrupt flows to include VF Signed-off-by:

If fan failure is detected, MCP prevents PCI I/O registers from being mapped to the bar, causing a fatal error as driver is unaware. This patch recognizes such an event occurred and gracefully terminates the probe process. Signed-off-by:

This patch replaces the BCM_CNIC define with a flag which can change at run-time and which does not use the CONFIG_CNIC kconfig option. For the PF/hypervisor driver cnic is always supported, however allocation of cnic resources and configuration of the HW for offload mode is done only when the cnic module registers bnx2x.

The flow in which the bnx2x driver starts after a previous driver has been terminated in an 'unclean' manner has several bugs and FW risks, which makes it possible for the driver to fail after boot-from-SAN or kdump. This patch contains a revised flow which performs a safer initialization, solving the possible crash scenarios. Notice this patch contains lines with over 80 characters, as it keeps print-strings in a single line. Signed-off-by:

Use hardware locks to protect resources common to several Physical Functions. In a virtualized environment the RTNL lock only protects a PF's driver against the PFs sharing it's VMs with regard to device resources. Other PFs may reside in other VMs under other OSs, and are not subject to the lock. Such resources which were previously protected implicitly by the RTNL lock must now be protected explicitly with dedicated HW locks. Signed-off-by:

This patch fixes both the failure in the self-test on 578xx and a hole in a parity recovery flow that this failure has discovered: - internal 'pending' state in a VLAN_MAC object wasn't been cleared when the object state change was called with DRV_ONLY flag, which in particular happens when a parity error happens during the self-test. - bp->sp_state wasn't cleared in the similar circumstances as described above.
