mlx4_core: Save/restore default port IB capability mask

2008-11-29T05:29:46+00:00

Commit 7ff93f8b ("mlx4_core: Multiple port type support") introduced support for different port types. As part of that support, SET_PORT is invoked to set the port type during driver startup. However, as a side-effect, for IB ports the invocation of this command also sets the port's capability mask to zero (losing the default value set by FW). To fix this, get the default ib port capabilities (via a MAD_IFC Port Info query) during driver startup, and save them for use in the mlx4_SET_PORT command when setting the port-type to Infiniband. This patch fixes problems with subnet manager (SM) failover such as , which occurred because the IsTrapSupported bit in the capability mask was zeroed.

mlx4_core: Multiple port type support

2008-10-22T22:38:42+00:00

Multi-protocol adapters support different port types. Each consumer of mlx4_core queries for supported port types; in particular mlx4_ib can no longer assume that all physical ports belong to it. Port type is configured through a sysfs interface. When the type of a port is changed, all mlx4 interfaces are unregistered, and then registered again with the new port types.

mlx4_core: Ethernet MAC/VLAN management

2008-10-22T18:44:46+00:00

Add support for managing MAC and VLAN filters for each port. Signed-off-by: Yevgeny Petrilin Signed-off-by: Oren Duer Signed-off-by: Roland Dreier

mlx4_core: Get ethernet MTU and default address from firmware

2008-10-22T17:56:48+00:00

Get maximum ethernet MTU and default MAC address from the firmware QUERY_DEV_CAP command. Signed-off-by: Yevgeny Petrilin Signed-off-by: Roland Dreier

mlx4_core: Support multiple pre-reserved QP regions

2008-10-22T17:25:29+00:00

For ethernet support, we need to reserve QPs for the ethernet and fibre channel driver. The QPs are reserved at the end of the QP table. (This way we assure that they are aligned to their size) We need to consider these reserved ranges in bitmap creation, so we extend the mlx4 bitmap utility functions to allow reserved ranges at both the bottom and the top of the range.

mlx4_core: Add QP range reservation support

2008-10-10T19:01:37+00:00

To allow allocating an aligned range of consecutive QP numbers, add an interface to reserve an aligned range of QP numbers and have the QP allocation function always take a QP number. This will be used for RSS support in the mlx4_en Ethernet driver and also potentially by IPoIB RSS support. Signed-off-by: Yevgeny Petrilin Signed-off-by: Roland Dreier

IB/mlx4: Fix up fast register page list format

2008-09-15T21:25:23+00:00

Byte swap the addresses in the page list for fast register work requests to big endian to match what the HCA expectx. Also, the addresses must have the "present" bit set so that the HCA knows it can access them. Otherwise the HCA will fault the first time it accesses the memory region.

mlx4_core: Add ethernet fields to CQE struct

2008-08-07T03:14:06+00:00

Add ethernet-related fields to struct mlx4_cqe so that the mlx4_en ethernet NIC driver can share the same definition. Signed-off-by: Yevgeny Petrilin Signed-off-by: Roland Dreier

mlx4_core: Add VLAN tag field to WQE control segment struct

2008-07-25T17:30:06+00:00

Add fields for VLAN tag and insert VLAN tag flag to the control section struct. These fields will be used for sending ethernet packets. Signed-off-by: Yevgeny Petrilin Signed-off-by: Roland Dreier

IB/mlx4: Add support for memory management extensions and local DMA L_Key

2008-07-23T15:12:26+00:00

Add support for the following operations to mlx4 when device firmware supports them: - Send with invalidate and local invalidate send queue work requests; - Allocate/free fast register MRs; - Allocate/free fast register MR page lists; - Fast register MR send queue work requests; - Local DMA L_Key.
