IB/hfi1: Remove write(), use ioctl() for user cmds

2016-05-26T15:35:13Z

Remove the write() handler for user space commands now that ioctl handling is available. User apps will need to change to use ioctl from this point forward. Reviewed-by: Mitko Haralanov Signed-off-by: Dennis Dalessandro Signed-off-by: Doug Ledford

IB/hfi1: Add ioctl() interface for user commands

2016-05-26T15:35:06Z

IOCTL is more suited to what user space commands need to do than the write() interface. Add IOCTL definitions for all existing write commands and the handling for those. The write() interface will be removed in a follow on patch.

IB/hfi1: Remove multiple device cdev

2016-05-26T15:23:17Z

hfi1 current exports a cdev that can be used to target all of the hfi's in the system. However there is a problem with this approach in that the devices could be on different subnets. This is a problem that user space can figure out and explicitly tell the driver on which device to create a context. Remove the multi-purpose cdev leaving a dedicated cdev for each port. Also remove the striping capability that is dependent upon the user choosing the multi-purpose cdev. It is now up to user space to determine how to stripe contexts.

The client request would include the ifindex of the outgoing interface and would place in an attribute (LS_NLA_TYPE_IPV4 or LS_NLA_TYPE_IPV6) the destnation IP. The local service would answer with a message that has the attribute: - LS_NLA_TYPE_DGID - The destination GID. Signed-off-by: Mark Bloch Signed-off-by: Doug Ledford

IB/core: Add extended device capability flags

2016-05-13T23:40:27Z

Since all the uverbs device_cap_flags are occupied, we need a place to expose more device capabilities. This patch adds a new 64 bit device_cap_flags_ex to expose new device capabilities. The lower 32 bits will be identical to the original device_cap_flags, The upper 32 bits will be new capabilities. Signed-off-by: Majd Dibbiny Signed-off-by: Matan Barak Signed-off-by: Doug Ledford
