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.

staging/hfi1: Enable TID caching feature

2016-02-29T22:10:39+00:00

This commit "flips the switch" on the TID caching feature
implemented in this patch series.

As well as enabling the new feature by tying the new function
with the PSM API, it also cleans up the old unneeded code,
data structure members, and variables.

Due to difference in operation and information, the tracing
functions related to expected receives had to be changed. This
patch include these changes.

The tracing function changes could not be split into a separate
commit without including both tracing variants at the same time.
This would have caused other complications and ugliness.

uapi/hfi1_user: Add command and event for TID caching

2016-02-29T22:10:38+00:00

TID caching will use a new event to signal userland that cache
invalidation has occurred and needs a matching command code that
will be used to read the invalidated TIDs.

Add the event bit and the new command to the exported header file.

The command is also added to the switch() statement in file_ops.c
for completeness and in preparation for its usage later.
