docs: infiniband: convert docs to ReST and rename to *.rst

2019-06-25T13:23:09+00:00

The InfiniBand docs are plain text with no markups. So, all we needed to do were to add the title markups and some markup sequences in order to properly parse tables, lists and literal blocks. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Jason Gunthorpe

treewide: Add SPDX license identifier - Makefile/Kconfig

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

2011-01-21T01:02:05+00:00

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.

IPoIB: Remove LRO support

2011-01-11T01:41:54+00:00

As a first step in moving from LRO to GRO, revert commit af40da894e9 ("IPoIB: add LRO support"). Also eliminate the ethtool set_flags callback which isn't needed anymore. Finally, we need to include directly to get the declaration of restart_syscall() (which used to be included implicitly through ). Cc: Ben Hutchings Cc: Eric W.

IPoIB: Correct help text for INFINIBAND_IPOIB_DEBUG

2008-07-25T03:37:25+00:00

The help text for INFINIBAND_IPOIB_DEBUG refers to "ipoib_debugfs," which no longer exists. Correct this to talk about the files under debugfs that are really created. Signed-off-by: Roland Dreier

IPoIB/cm: Connected mode is no longer EXPERIMENTAL

2008-07-25T03:37:25+00:00

Connected mode is now tested and used by lots of people. No need to hide it under CONFIG_EXPERIMENTAL. Signed-off-by: Roland Dreier

IPoIB: add LRO support

2008-07-15T06:48:48+00:00

Add "ipoib_use_lro" module parameter to enable LRO and an "ipoib_lro_max_aggr" module parameter to set the max number of packets to be aggregated. Make LRO controllable and LRO statistics accessible through ethtool. Signed-off-by: Vladimir Sokolovsky Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier

IB: Use menuconfig for InfiniBand menu

Change Kconfig objects from "menu, config" into "menuconfig" so that the user can disable the whole feature without having to enter the menu first. Signed-off-by: Jan Engelhardt Signed-off-by: Andrew Morton Signed-off-by: Roland Dreier

IPoIB: Connected mode experimental support

2007-02-10T16:00:48+00:00

The following patch adds experimental support for IPoIB connected mode, as defined by the draft from the IETF ipoib working group. The idea is to increase performance by increasing the MTU from the maximum of 2K (theoretically 4K) supported by IPoIB on top of UD. With this code, I'm able to get 800MByte/sec or more with netperf without options on a Mellanox 4x back-to-back DDR system. Some notes on code: 1. SRQ is used for scalability to large cluster sizes 2. Only RC connections are used (UC does not support SRQ now) 3. Retry count is set to 0 since spec draft warns against retries 4. Each connection is used for data transfers in only 1 direction, so each connection is either active(TX) or passive (RX). 2 sides that want to communicate create 2 connections. 5. Each active (TX) connection has a separate CQ for send completions - this keeps the code simple without CQ resize and other tricks 6. To detect stale passive side connections (where the remote side is down), we keep an LRU list of passive connections (updated once per second per connection) and destroy a connection after it has been unused for several seconds. The LRU rule makes it possible to avoid scanning connections that have recently been active. Signed-off-by: Michael S. Tsirkin Signed-off-by: Roland Dreier
