2012-06-01net/mlx4_core: Fix number of EQs used in ICM initialisationMarcel Apfelbaum1-0/+6
In SRIOV mode, the number of EQs used when computing the total ICM size was incorrect. To fix this, we do the following: 1. We add a new structure to mlx4_dev, mlx4_phys_caps, to contain physical HCA capabilities. The PPF uses the phys capabilities when it computes things like ICM size. The dev_caps structure will then contain the paravirtualized values, making bookkeeping much easier in SRIOV mode. We add a structure rather than a single parameter because there will be other fields in the phys_caps. The first field we add to the mlx4_phys_caps structure is num_phys_eqs. 2. In INIT_HCA, when running in SRIOV mode, the "log_num_eqs" parameter passed to the FW is the number of EQs per VF/PF; each function (PF or VF) has this number of EQs available. However, the total number of EQs which must be allowed for in the ICM is (1 << log_num_eqs) * (#VFs + #PFs). Rather than compute this quantity, we allocate ICM space for 1024 EQs (which is the device maximum number of EQs, and which is the value we place in the mlx4_phys_caps structure). For INIT_HCA, however, we use the per-function number of EQs as described above.

2012-05-08mlx4_core: Add second capabilities flags fieldShlomo Pongratz1-0/+8
This patch adds a 64-bit flags2 features member to struct mlx4_dev to export further features of the hardware. The original flags field tracks features whose support bits are advertised by the firmware in offsets 0x40 and 0x44 of the query device capabilities command. flags2 will track features whose support bits are scattered at various offsets. RSS support is the first feature to be exported through flags2. RSS capabilities are located at offset 0x2e. The size of the RSS indirection table is also given in this offset.

2012-04-05net/mlx4_en: Force user priority by QP attributeAmir Vadai1-1/+2
Instead of relying on HW to change schedule queue by UP, schedule queue is fixed for a tx_ring, and UP in WQE is ignored in this aspect. This resolves two issues with untagged traffic: 1. untagged traffic has no UP in packet which is needed for QoS. The change above allows setting the schedule queue (and by that the UP) of such a stream. 2. BlueFlame uses the same field used by vlan tag. So forcing UP from QPC allows using BF for untagged but prioritized traffic. In old firmware that force UP is not supported, untagged traffic will not subject to QoS. Because UP is set by QP, need to always have a tx ring per UP, even if pfcrx module paramter is false. Signed-off-by: Amir Vadai <amirv@mellanox.com> Signed-off-by: David S.

2012-03-16device.h: audit and cleanup users in main include dirPaul Gortmaker1-1/+0
The <linux/device.h> header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

2012-03-13mlx4_core: Allow dynamic MTU configuration for IB portsOr Gerlitz1-0/+1
Set the MTU for IB ports in the driver instead of using the firmware default of 2KB (the driver defaults to 4KB). Allow for dynamic mtu configuration through a new, per-port sysfs entry. Since there's a dependency between the port MTU and the max number of HW VLs the port can support, apply a mim/max approach, using a loop that goes down from the highest possible number of VLs to the lowest, using the firmware return status to know whether the requested number of VLs is possible with a given MTU. For now, as with the dynamic link type change / VPI support, the sysfs entry to change the mtu is exposed only when NOT running in SR-IOV mode. To allow changing the MTU for the master in SR-IOV mode, primary-function-initiated FLR (Function Level Reset) needs to be implemented.

Therefore commit 97285b7817 ("mlx4_core: Add extended port capabilities support") adds redundant code into the driver, since there's no real reaon to maintain the extended capabilities of the port, as they can be queried on demand (e.g the FDR10 capability).

2011-12-13mlx4_core: Modify driver initialization flow to accommodate SRIOV for EthernetJack Morgenstein2-0/+3
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.

2011-07-19mlx4_core: Read extended capabilities into the flags fieldOr Gerlitz1-6/+6
Query another dword containing up to 32 extended device capabilities and merge it into struct mlx4_caps.flags. Update the code that handles the current extended device capabilities (e.g UDP RSS, WoL, vep steering, etc) to use the extended device cap flags field instead of a field per extended capability.

2011-03-23mlx4: Add blue flame support for kernel consumersEli Cohen2-0/+14
Using blue flame can improve latency by allowing the HW to more efficiently access the WQE. This patch presents two functions that are used to allocate or release HW resources for using blue flame; the caller need to supply a struct mlx4_bf object when allocating resources. Consumers that make use of this API should post doorbells to the UAR object pointed by the initialized struct mlx4_bf; Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: David S.

2011-03-23mlx4_en: Enabling new steeringYevgeny Petrilin1-3/+9
The mlx4_en module now uses the new steering mechanism. The RX packets are now steered through the MCG table instead of Mac table for unicast, and default entry for multicast. The feature is enabled through INIT_HCA Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-03-23mlx4: Changing interrupt schemeYevgeny Petrilin1-0/+8
Adding a pool of MSI-X vectors and EQs that can be used explicitly by mlx4_core customers (mlx4_ib, mlx4_en). The consumers will assign their own names to the interrupt vectors. Those vectors are not opened at mlx4 device initialization, opened by demand. Changed the max number of possible EQs according to the new scheme, no longer relies on on number of cores. The new functionality is exposed through mlx4_assign_eq() and mlx4_release_eq(). Customers that do not use the new API will get completion vectors as before.

2011-01-13IB/mlx4: Handle protocol field in multicast tableAleksey Senin2-7/+9
The newest device firmware stores IB vs. Ethernet protocol in two bits in members_count field of multicast group table (0: Infiniband, 1: Ethernet). When changing the QP members count for a multicast group, it important not to reset this information. When calling multicast attach first time, the protocol type should be specified. In this patch we always set it IB, but in the future we will handle Ethernet too. When looking for a QP, the protocol type shoud be checked too.
