2011-03-23mlx4_core: reserve UARs for userspace consumersEli Cohen1-0/+8
Do not allow a kernel consumer to allocate a UAR to serve for blue flame if the number of available UARs gets below MLX4_NUM_RESERVED_UARS (currently 8).

2011-03-23mlx4_core: maintain available field in bitmap allocatorEli Cohen2-0/+15
Add mlx4_bitmap_avail() to give the number of available resources. We want to use this as a hint to whether to allocate a resources or not. This patch is introduced to be used with allocation blue flame registers. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-23mlx4: Add blue flame support for kernel consumersEli Cohen3-0/+128
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 Petrilin8-58/+291

2011-03-23mlx4: Add support for promiscuous mode in the new steering model.Yevgeny Petrilin3-11/+620
For Ethernet mode only, When we want to register QP as promiscuous, it must be added to all the existing steering entries and also to the default one. The promiscuous QP might also be on of "real" QPs, which means we need to monitor every entry to avoid duplicates and ensure we close an entry when all it has is promiscuous QPs. Same mechanism both for unicast and multicast. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>

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.

2011-03-22IB: Increase DMA max_segment_size on Mellanox hardwareDavid Dillow1-0/+3
By default, each device is assumed to be able only handle 64 KB chunks during DMA. By giving the segment size a larger value, the block layer will coalesce more S/G entries together for SRP, allowing larger requests with the same sg_tablesize setting. The block layer is the only direct user of it, though a few IOMMU drivers reference it as well for their *_map_sg coalescing code. pci-gart_64 on x86, and a smattering on on sparc, powerpc, and ia64. Since other IB protocols could potentially see larger segments with this, let's check those: - iSER is fine, because you limit your maximum request size to 512 KB, so we'll never overrun the page vector in struct iser_page_vec (128 entries currently). It is independent of the DMA segment size, and handles multi-page segments already. - IPoIB is fine, as it maps each page individually, and doesn't use ib_dma_map_sg(). - RDS appears to do the right thing and has no dependencies on DMA segment size, but I don't claim to have done a complete audit. - NFSoRDMA and 9p are OK -- they do not use ib_dma_map_sg(), so they doesn't care about the coalescing. - Lustre's ko2iblnd does not care about coalescing -- it properly walks the returned sg list. This patch ups the value on Mellanox hardware to 1 GB, which matches reported firmware limits on mlx4.

2011-01-12IB/mlx4: Handle protocol field in multicast tableAleksey Senin1-10/+13
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.

The kernel warning message added in commit 58d74bb1d9f7 ("mlx4_core: Workaround firmware bug in query dev cap") about mlx4 reporting the wrong number of "blue flame registers" doesn't really help anyone, since the firmware bug is known and fixed and the bug is pretty much harmless to users.

2010-12-01mlx4_core: Workaround firmware bug in query dev capEli Cohen1-0/+4
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.

2010-10-25IB/mlx4: Add VLAN support for IBoEEli Cohen3-0/+30
This patch allows IBoE traffic to be encapsulated in 802.1Q tagged VLAN frames. The VLAN tag is encoded in the GID and derived from it by a simple computation. The netdev notifier callback is modified to catch VLAN device addition/removal and the port's GID table is updated to reflect the change, so that for each netdevice there is an entry in the GID table. When the port's GID table is exhausted, GID entries will not be added. Only children of the main interfaces can add to the GID table; if a VLAN interface is added on another VLAN interface (e.g. "vconfig add eth2.6 8"), then that interfaces will not add an entry to the GID table.

For this, an exported function, mlx4_get_protocol_dev() is added, which allows a driver to get some other driver's device based on the protocol that the driver implements. Two protocols are added: MLX4_PROTOCOL_IB and MLX4_PROTOCOL_EN. This will be used in mlx4 IBoE support so that mlx4_ib can find the corresponding mlx4_en netdev.

2010-10-21vlan: Don't check for vlan group before vlan_tx_tag_present.Jesse Gross1-2/+2
Many (but not all) drivers check to see whether there is a vlan group configured before using a tag stored in the skb. There's not much point in this check since it just throws away data that should only be present in the expected circumstances. However, it will soon be legal and expected to get a vlan tag when no vlan group is configured, so remove this check from all drivers to avoid dropping the tags.
