Hello David,
This patch set adds SRIOV support for ConnectX2 and ConnectX3 HW for Ethernet
Link layer.
Infiniband and RoCE SRIOV support will be added at later stage
In ConnectX, nearly all device resources can be associated with any function.
Once allocated, these resources can be manipulated
From: Jack Morgenstein ja...@dev.mellanox.co.il
These changes will not affect module operation as yet. They
are only to get some structs and enums in place for use by
subsequent patches (making those smaller).
Added here:
* sriov state structs and inlines (mlx4_is_master/slave/mfunc)
*
From: Jack Morgenstein ja...@dev.mellanox.co.il
Port mask now has additional state.
Port can be set as none. In this case neither the mlx4_en or mlx4_ib
drivers take ownership of the port.
In multifunction mode there is an option to set the vfs as single ported
devices.
This option will be added

For SRIOV, some Hypervisor commands can be executed directly (native = 1).
Others should go through the command wrapper flow (for tracking resource
usage, for example, or for changing some HCA configurations that slaves
need to be notified of).
From: Jack Morgenstein ja...@dev.mellanox.co.il
When SRIOV is enabled on the chip (at FW burning time),
the HCA uses only 17 bits for the PD. The remaining 7 high-order bits
are ignored.
Change the allocator to return only 17 bits for the PD. The MSB 7
bits will be used to encode the slave

When SRIOV is enabled, pf and vfs communicate via shared comm channel.
The vf gets its side of the comm channel via a VF BAR.
Each VF (slave) creates its vHCR (virtual HCA Command Register),
Its DMA address is passed to the PF (master) using

The following commands are added here:
1. QUERY_FUNC_CAP and its wrapper. This function is used by VFs when
they start up to receive configuration information from the PF, such
as resource quotas for this VF, which ports should be used

SRQs are resources which are allocated and tracked by the PF driver.
In multifunction mode, the allocation and icm mapping is done in
the resource tracker (later patch in this sequence).

Passing async events to slaves:

register directly with the FW to receive async events. Async events which

The physical port is now common to the PF and VFs.

Subject: [PATCH 17/21] mlx4_core: mtts resources units changed to offset
In the previous implementation mtts are managed by:
1. order - log(mtt segments), 'mtt segment' groups several mtts together.

When running in SRIOV mode, driver should not automatically start/stop

sriov, which will cause the hypervisor to hang if there are running VMs with
attached VFs.

At least AF_INET_SDP - there might have been other issues. See e.g.
