RDMA/hfi1: Avoid redeclaration error

2017-01-10T17:41:40+00:00

Move hfi1 ioctl definitions to a new header which can be included by
both the hfi1 and qib drivers to avoid a duplicate enum definition
as shown in this build error for qib:

  CC [M] drivers/infiniband/hw/qib/qib_sysfs.o
In file included from ./include/uapi/rdma/rdma_user_ioctl.h:39:0,

./include/uapi/rdma/hfi/hfi1_user.h:370:2: error: redeclaration of
enumerator ‘ur_rcvhdrtail’
  ur_rcvhdrtail = 0,

Move hfi1 structures to separate file to avoid this failure.

The actual move of the ioctl definitions comes in a follow on patch.

IB/hfi1: Disable header suppression for short packets

2016-12-11T20:25:13+00:00

For the received packets with payload less or equal 8DWS
RxDmaDataFifoRdUncErr is not reported. There is set RHF.EccErr
if the header is not suppressed. When such packet is detected
on the send side the header suppression mechanism is disabled
by clearing SH bit in the packet header.

IB/hfi1: Allow for non-double word multiple message sizes for user SDMA

2016-08-03T02:46:21+00:00

The driver pads non-double word multiple message sizes but it doesn't
account for this padding when the packet length is calculated. Also, the
data length is miscalculated for message sizes less than 4 bytes due to
the bit representation in LRH. And there's a check for non-double word
multiple message sizes that prevents these messages from being sent.
This patch fixes length miscalculations and enables the functionality to
send non-double word multiple message sizes.

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

2016-05-26T15:35:13+00:00

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.

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

2016-05-26T15:35:06+00:00

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

2016-05-26T15:23:17+00:00

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.
