module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. (Thanks to Joe Perches for suggesting coccinelle for 0/1 -> true/false). Cc: "David S.

New FW can give clues to driver regarding default port type and whether or not we should default to link sensing on the port. 2 bits are added to QUERY_PORT command: 1. suggested_type: This bit gives a hint whether the default port type should be IB or Ethernet. The driver will use this hint in case the user didn't specify explicitly the link layer type he wants to set. 2. default_sense: If this bit is set, we would sense the port type on start-up and default the port to link sensing Signed-off-by: NYevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: NDavid S.

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.

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 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.

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.

ConnectX firmware is supposed to report the number blue flame registers per page as log2 of the value. However, due to a firmware bug, it reports actual number. This patch works around this by checking if the number of registers calculated fits within a page. If it does not, we use 8 registers per page.

Current code has a limitation: an LSO header is not allowed to cross a 64 byte boundary. This patch removes this limitation by setting the WQE RR for large headers thus allowing LSO headers of any size. The extra buffer reserved for MLX4_IB_QP_LSO QPs has been doubled, from 64 to 128 bytes, assuming this is reasonable upper limit for header length. Also, this patch will cause IB_DEVICE_UD_TSO to be set only for HCA FW versions that set MLX4_DEV_CAP_FLAG_BLH; e.g. FW version 2.6.000 and higher.

There was a bug in some versions of the mlx4 driver in mlx4_alloc_fmr(), which hardcoded the minimum acceptable page_shift to be 12. However, new ConnectX firmware can support a minimum page_shift of 9 (log_pg_sz of 9 returned by QUERY_DEV_LIM) -- so with old drivers, ib_fmr_alloc() would fail for ULPs using the device minimum when creating FMRs. To preserve firmware compatibility with released mlx4 drivers, the firmware will continue to return 12 as before for log_page_sz in QUERY_DEV_CAP for these drivers. However, to enable new drivers to take advantage of the available smaller page size, the mlx4 driver now first sets the log_pg_sz to the device minimum by setting a log_page_sz value to 0 via the MOD_STAT_CFG command and then reading the real minimum via QUERY_DEV_CAP.
