1. Added module parameters sr_iov and probe_vf for controlling enablement of SRIOV mode. 2. Increased default max num-qps, num-mpts and log_num_macs to accomodate SRIOV mode 3. Added port_type_array as a module parameter to allow driver startup with ports configured as desired. In SRIOV mode, only ETH is supported, and this array is ignored; otherwise, for the case where the FW supports both port types (ETH and IB), the port_type_array parameter is used. By default, the port_type_array is set to configure both ports as IB. 4. When running in sriov mode, the master needs to initialize the ICM eq table to hold the eq's for itself and also for all the slaves. 5. mlx4_set_port_mask() now invoked from mlx4_init_hca, instead of in mlx4_dev_cap. 6. Introduced sriov VF (slave) device startup/teardown logic (mainly procedures mlx4_init_slave, mlx4_slave_exit, mlx4_slave_cap, mlx4_slave_exit and flow modifications in __mlx4_init_one, mlx4_init_hca, and mlx4_setup_hca). VFs obtain their startup information from the PF (master) device via the comm channel. 7. In SRIOV mode (both PF and VF), MSI_X must be enabled, or the driver aborts loading the device. 8. Do not allow setting port type via sysfs when running in SRIOV mode. 9. mlx4_get_ownership: Currently, only one PF is supported by the driver. If the HCA is burned with FW which enables more than one PF, only one of the PFs is allowed to run. The first one up grabs a FW ownership semaphone -- all other PFs will find that semaphore taken, and the driver will not allow them to run.

When running in SRIOV mode, driver should not automatically start/stop the mlx4_core upon sensing an HCA internal error -- doing this disables/enables sriov, which will cause the hypervisor to hang if there are running VMs with attached VFs. In addition, on VMs the catas process should not run at all, since the HCA error buffer is not available to VMs in the BARs.

In the previous implementation mtts are managed by: 1. order - log(mtt segments), 'mtt segment' groups several mtts together. 2. first_seg - segment location relative to mtt table. In the current implementation: 1. order - log(mtts) rather than segments 2. offset - mtt index in mtt table Note: The actual mtt allocation is made in segments but it is transparent to callers. Rational: The mtt resource holders are not interested on how the allocation of mtt is done, but rather on how they will use it.

The physical port is now common to the PF and VFs. The port resources and configuration is managed by the PF, VFs can only influence the MTU of the port, it is set as max among all functions, Each function allocates RX buffers of required size to meet it's MTU enforcement.

The resource tracker is used to track usage of HCA resources by the different guests. Virtual functions (VFs) are attached to guest operating systems but resources are allocated from the same pool and are assigned to VFs. It is essential that hostile/buggy guests not be able to affect the operation of other VFs, possibly attached to other guest OSs since ConnectX firmware is not tolerant to misuse of resources. The resource tracker module associates each resource with a VF and maintains state information for the allocated object. It also defines allowed state transitions and enforces them. Relationships between resources are also referred to. For example, CQs are pointed to by QPs, so it is forbidden to destroy a CQ if a QP refers to it. ICM memory is always accessible through the primary function and hence it is allocated by the owner of the primary function. When a guest dies, an FLR is generated for all the VFs it owns and all the resources it used are freed. The tracked resource types are: QPs, CQs, SRQs, MPTs, MTTs, MACs, RES_EQs, and XRCDNs.

Passing async events to slaves: In SRIOV mode, each slave creates its own async EQ, but only the master can register directly with the FW to receive async events. Async events which should be passed to slaves (such as a WQ_ACCESS_ERROR for a QP owned by a slave) are generated at the slave by the master using the GEN_EQE FW command. Wrapper functions: mlx4_MAP_EQ_wrapper Only the master can map an EQ. The slave commands to map their EQs arrive at the master via the comm channel. The master then invokes the wrapper function to do the work (and enter the resource in the tracking database). New events: COMM_CHANNEL and FLR The COMM_CHANNEL event arrives only at the master, and signals that a slave has posted a command on the comm channel. The FLR event is generated by the FW when a guest operating a VF unexpectedly goes down. Signed-off-by: NJack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: NDavid S.

MTTs 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). To accomplish this, we have "work" functions whose names start with "__", and "request" functions (same name, no __). If we are operating in multifunction mode, the request function actually results in comm-channel commands being sent (ALLOC_RES or FREE_RES). The PF-driver comm-channel handler will ultimately invoke the "work" (__) function and return the result. If we are not in multifunction mode, the "work" handler is invoked immediately.

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 (currently two), what protocol is running on the port (currently Ethernet ONLY, or port not active). 2. QUERY_PORT and its wrapper. Previously, this FW command was invoked directly by the ETH driver (en_port.c) using mlx4_cmd_box. Virtualization is now required here (the VF's MAC address must be substituted for the PFs MAC address returned by the FW). We changed the invocation in the ETH driver to use mlx4_QUERY_PORT, and added the wrapper. 3. QUERY_HCA. Used by the VF to determine how the HCA was initialized. For now, we need only the multicast table member entry size (log2_mc_table_entry_sz, in the ConnectX PRM). No wrapper is needed here, because the data may be passed as is to the VF without modification). In this command, we have added a GLOBAL_CAPS field for passing required configuration information from FW to a VF (this field is to allow safely adding new SRIOV capabilities which require support in VF drivers, too). Bits will set here by FW in response to PF-driver configuration commands which will activate as yet undefined new SRIOV features. The VF will test to see that all required capabilities indicated by this field are supported (i.e., if a bit is set and the VF driver does not recognize that bit, it must abort its initialization). Currently, no bits are set. 4. Added a CLOSE_PORT wrapper. The PF context needs to keep track of how many VF contexts have the port open. The PF context will not actually issue the FW close port command until the last port user issues a CLOSE_PORT request.

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 Communication Channel Register. The same Register is used to notify the master of commands posted by the slaves and for the master to pass events to the slaves, such as command completions and asynchronous events. The vHCR format is identical to the HCR format, except for the 'go' and 't' bits, which are reserved in the vHCR. Posting commands to the vHCR is identical to the way it is done with the HCR, albeit that the function/PF token fields are used instead of the HCR go bit. Specifically: - When the function prepares a new command in the vHCR, it issues the Post_vHCR_cmd communication channel command and toggles the value of the function token; when PF token has an equal value, the command has been accepted and a new command may be posted. - When the PF detects a Post_vHCR_cmd command, it concludes that a new command is available in the vHCR; after processing the command, the PF toggles the PF token to match the function token. When the 'e' bit is not set, the completion of a Post_vHCR_cmd command also indicates the completion the vHCR command. If, however, the 'e' bit is set, the completion of a Post_vHCR_cmd command only indicates that the vHCR command has been accepted for execution by the PF. Function commands are processed by the PF as follows: -DMA (using the ACCESS_MEM command) the vHCR image into a shadow buffer. -Validate that the opcode is non-privileged, and that the opcode- and input-modifiers are legal. -DMA the in-box (if required) into a shadow buffer. -Validate the command: o Resource ranges (e.g., QP ranges). o Partition key. o Ranges of referenced resources (e.g., CQs within QP contexts). -If the 'e' bit is set o complete the Post_vHCR_cmd command -Execute the command on the HCR. -DMA the results to the vHCR out-box (if required). -If the 'e' bit is set o Indicate command completion by generating a completion event using the GEN_EQE command -Otherwise o DMA the command status to the vHCR o Complete the Post_vHCR_cmd command Signed-off-by: NJack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: NYevgeny Petrillin <yevgenyp@mellanox.com> Signed-off-by: NLiran Liss <liranl@mellanox.com> Signed-off-by: NDavid S.

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). This patch sets the groundwork for this capability -- adding the correct value of "native" in each case. Note that if SRIOV is not activated, this parameter has no effect.

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) * comm-channel and vhcr support structures * enum values for new FW and comm-channel virtual commands (i.e., commands, passed via the comm channel to the PF-driver). * prototypes for many command wrapper functions (used by the PF context for processing FW commands passed to it by the VFs). * struct mlx4_eqe is moved from eq.c to mlx4.h (it will be used by other mlx4_core source files).
