OVERVIEW
--------
1) Setting .rxmode.mq_mode for bonding device to ETH_MQ_RX_RSS makes bonding
device fully RSS-capable, so all slaves are synchronized with its configuration.
This mode is intended to provide RSS configuration as known from "dynamic RSS
configuration for one port" and made slaves transparent for client application
implementation.
2) If .rxmode.mq_mode for bonding device isn't ETH_MQ_RX_RSS, slaves are not
synchronized. That provides an ability to configure them manually. This mode may
be useful when application wants to manage RSS in an unusual way and the
consistency of RSS configuration for slaves isn't required.
Turning on/off RSS mode for slaves when bonding is started is not possible.
Other RSS configuration is propagated over slaves, when bonding device API is
used to do it.

It stores its own copies of settings i.e. RETA, RSS hash function and RSS key. It’s required to ensure consistency. 1) RSS hash function set for bonding device is maximal set of RSS hash functions supported by all bonded devices. That mean, to have RSS support for bonding, all slaves should be RSS-capable. 2) RSS key is propagated over the slaves "as is", and is always 40 bytes long. 3) RETA for bonding is an internal table managed by bonding API, and is used as a pattern to set up slaves. Its size is GCD of all RETA sizes, so it can be easily used as a pattern providing expected behavior, even if slaves RETA sizes are different.

Do it for all slaves. b) Repeat above for RSS key and RETA. 2)Dynamic adding slave to the bonding a) Remove slave from bonding. b) Change its configuration to other than bonding. c) Add slave to the started bonding device. d) Check if slaves configuration changed. 3) Repeat point 1) and 2) with RSS multi-queue mode enabled/disabled for bonding port.

This mode is intended to provide RSS configuration as known from "dynamic RSS configuration for one port" and made slaves transparent for client application implementation. 2) If .rxmode.mq_mode for bonding device isn't ETH_MQ_RX_RSS, slaves are not synchronized. That provides an ability to configure them manually. This mode may be useful when application wants to manage RSS in an unusual way and the consistency of RSS configuration for slaves isn't required. Turning on/off RSS mode for slaves when bonding is started is not possible. Other RSS configuration is propagated over slaves, when bonding device API is used to do it. v2 changes: - added support for keys other than 40 bytes long, - now, if RSS key is not set for bonding, it is not set also for slaves, - fix - full initial RSS configuration before any slave is added was not possible due to the initially zeroed flow_type_rss_offloads for bonding, - fix - changed error to warning when slave is synchronizing due to the bonding's initial configuration (to allow use slaves' drivers not supporting dynamic RSS configuration in bonding), - some code cleanups, - updated documentation, Tomasz Kulasek (8): bond: rss dynamic configuration ring: dynamic rss configuration test: dynamic rss configuration bond: queue stats mapping ring: queue stats mapping set dummy implementation examples: dynamic rss configuration for bonding doc: fixed spellings and typos doc: dynamic rss configuration for bonding app/test/Makefile | 1 + app/test/test_link_bonding_rssconf.c | 674 ++++++++++++++ .../prog_guide/link_bonding_poll_mode_drv_lib.rst | 42 +- drivers/net/bonding/rte_eth_bond_api.c | 27 + drivers/net/bonding/rte_eth_bond_pmd.c | 239 ++++- drivers/net/bonding/rte_eth_bond_private.h | 12 + drivers/net/ring/rte_eth_ring.c | 133 ++- examples/bond_rss/Makefile | 59 ++ examples/bond_rss/bondrss.c | 293 +++++++ examples/bond_rss/bondrss.h | 163 ++++ examples/bond_rss/config.c | 251 ++++++ examples/bond_rss/ui.c | 920 ++++++++++++++++++++ 12 files changed, 2789 insertions(+), 25 deletions(-) create mode 100644 app/test/test_link_bonding_rssconf.c create mode 100644 examples/bond_rss/Makefile create mode 100644 examples/bond_rss/bondrss.c create mode 100644 examples/bond_rss/bondrss.h create mode 100644 examples/bond_rss/config.c create mode 100644 examples/bond_rss/ui.c -- 1.7.9.5 ^ permalink raw reply [flat|nested] 126+ messages in thread

It stores its own copies of settings i.e. RETA, RSS hash function and RSS key. It’s required to ensure consistency. 1) RSS hash function set for bonding device is maximal set of RSS hash functions supported by all bonded devices. That mean, to have RSS support for bonding, all slaves should be RSS-capable. 2) RSS key is propagated over the slaves "as is". 3) RETA for bonding is an internal table managed by bonding API, and is used as a pattern to set up slaves. Its size is GCD of all RETA sizes, so it can be easily used as a pattern providing expected behavior, even if slaves RETA sizes are different.

After initialization process, all accessible ports are attached to one bonding as slaves. Monitor screen is divided into five main parts: - Port selection (on the very top) - RSS Configuration for selected port including hash function, key and RETA - Incoming packets statistics - Incoming packets list for selected port - Status bar with contextual information about selected part Signed-off-by: Tomasz Kulasek <tomaszx.kulasek@intel.com> --- examples/bond_rss/Makefile | 59 +++ examples/bond_rss/bondrss.c | 293 ++++++++++++++ examples/bond_rss/bondrss.h | 163 ++++++++ examples/bond_rss/config.c | 251 ++++++++++++ examples/bond_rss/ui.c | 920 +++++++++++++++++++++++++++++++++++++++++++ 5 files changed, 1686 insertions(+) create mode 100644 examples/bond_rss/Makefile create mode 100644 examples/bond_rss/bondrss.c create mode 100644 examples/bond_rss/bondrss.h create mode 100644 examples/bond_rss/config.c create mode 100644 examples/bond_rss/ui.c diff --git a/examples/bond_rss/Makefile b/examples/bond_rss/Makefile new file mode 100644 index 0000000..db457a3 --- /dev/null +++ b/examples/bond_rss/Makefile @@ -0,0 +1,59 @@ +# BSD LICENSE +# +# Copyright(c) 2010-2015 Intel Corporation.

It stores its own copies of settings i.e. RETA, RSS hash function and RSS key. It’s required to ensure consistency. 1) RSS hash function set for bonding device is maximal set of RSS hash functions supported by all bonded devices. That mean, to have RSS support for bonding, all slaves should be RSS-capable. 2) RSS key is propagated over the slaves "as is". 3) RETA for bonding is an internal table managed by bonding API, and is used as a pattern to set up slaves.

Adding some fake RSS to the ring PMD (in order to test bonding) is weird. The ring PMD is not a driver for testing. Maybe that the null PMD would be more appropriate. By the way the current RSS implementation is really bound to Intel devices. Before applying it to more drivers, we have to make sure it is generic enough.

Maybe the RETA needs more abstraction. This is not RSS implementation, but implementation of Dynamic RSS Configuration, already existing, and well defined in official documentation for single port. I don't know where you see bounding to Intel device. It's an implementation of official API. Anyway I will appreciate for any comment and opinion on that and clarification what means more RETA abstraction in context of official API. I will check the possibility of moving it to the null pmd driver and will prepare new version for easier reviewing.

What do you mean by "official"? My concern is that the RSS API in ethdev comes from a time where DPDK was Intel DPDK.

Also I changed usage of ring pmd with null pmd like you suggested. You are right, it is better place. Thanks. I sent a v4 patch-set. This implementation is using an existing ethdev API for RSS and introduces generic enhancements for configuration of bonding slaves. If other devices need a more generic ethdev API then this should be treated separately and they can submit separate patches for this in a future release. ^ permalink raw reply [flat|nested] 126+ messages in thread

Do it for all slaves. b) Repeat above for RSS key and RETA. 2)Dynamic adding slave to the bonding a) Remove slave from bonding. b) Change its configuration to other than bonding. c) Add slave to the started bonding device. d) Check if slaves configuration changed. 3) Repeat point 1) and 2) with RSS multi-queue mode enabled/disabled for bonding port.

Some Intel devices use a mapping to select hardware queues which will have some stats. But we may have stats per queues without requiring such mapping. I may miss something but I suggest these 3 actions: - remove this patch - replace checks on stats_mapping by an ethdev flag - remove device-specific stats_mapping from ethdev ^ permalink raw reply [flat|nested] 126+ messages in thread

Anyway, this patch, for ring pmd, was intended more as a cleanup than feature and was inspired by implementation in virtio driver: virtio_ethdev.c: /* * It enables testpmd to collect per queue stats. */ static int virtio_dev_queue_stats_mapping_set(__rte_unused struct rte_eth_dev *eth_dev, __rte_unused uint16_t queue_id, __rte_unused uint8_t stat_idx, __rte_unused uint8_t is_rx) { return 0; } This patch can be safely removed, if you think such a cleanup is not required, or lack of this implementation should be common behavior for this case. That will cause only few more warning messages, if you want to use ring pmd as a slave in example application. Do you need v4? ^ permalink raw reply [flat|nested] 126+ messages in thread

It’s required to ensure consistency. 1) RSS hash function set for bonding device is maximal set of RSS hash functions supported by all bonded devices. That mean, to have RSS support for bonding, all slaves should be RSS-capable. 2) RSS key is propagated over the slaves "as is". 3) RETA for bonding is an internal table managed by bonding API, and is used as a pattern to set up slaves. Its size is GCD of all RETA sizes, so it can be easily used as a pattern providing expected behavior, even if slaves RETA sizes are different.

HI Tomasz, Sorry, my English is wrong. 'rte_null_pmd' is defined like below. static struct eth_driver rte_null_pmd = { .pci_drv = { .name = "rte_null_pmd", .drv_flags = RTE_PCI_DRV_DETACHABLE, }, }; I guess you may be able to use 'rte_null_pmd' instead of allocating one more eth_driver structure like below. struct eth_driver *eth_drv = NULL; eth_drv = rte_zmalloc_socket(name, sizeof(*eth_drv), 0, numa_node); Is it possible to use 'rte_null_pmd'?

This mode is intended to provide RSS configuration as known from "dynamic RSS configuration for one port" and made slaves transparent for client application implementation. 2) If .rxmode.mq_mode for bonding device isn't ETH_MQ_RX_RSS, slaves are not synchronized. That provides an ability to configure them manually. This mode may be useful when application wants to manage RSS in an unusual way and the consistency of RSS configuration for slaves isn't required. Turning on/off RSS mode for slaves when bonding is started is not possible. Other RSS configuration is propagated over slaves, when bonding device API is used to do it. v5 changes: - updated to DPDK 2.2 - removed copyright change from null device source - removed queue_stats_mapping_set from eth_dev_ops of bonding device - null pmd cleanups (removed unnecessary malloc, replaced memcpy with rte_memcpy) - fixed queues number configuration in null pmd v4 changes: - fixed copy-paste error, - removed example application as too complex and introducing a new dependency, - addapted null pmd to be used as testing device for dynamic RSS configuration, - addapted test units to use null pmd instead of ring pmd, - ring pmd is not used and changed in this patchset v3 changes: - checkpatch cleanups v2 changes: - added support for keys other than 40 bytes long, - now, if RSS key is not set for bonding, it is not set also for slaves, - fix - full initial RSS configuration before any slave is added was not possible due to the initially zeroed flow_type_rss_offloads for bonding, - fix - changed error to warning when slave is synchronizing due to the bonding's initial configuration (to allow use slaves' drivers not supporting dynamic RSS configuration in bonding), - some code cleanups, - updated documentation, Tomasz Kulasek (9): bonding: rss dynamic configuration null: fix segfault when null_pmd added to bonding null: extend number of virtual queues null: virtual dynamic rss configuration null: export eth_dev_null_create test: dynamic rss configuration bonding: per queue stats doc: fixed spellings and typos doc: dynamic rss configuration for bonding app/test/Makefile | 8 + app/test/test_link_bonding_rssconf.c | 679 ++++++++++++++++++++ .../prog_guide/link_bonding_poll_mode_drv_lib.rst | 42 +- drivers/net/bonding/rte_eth_bond_api.c | 28 + drivers/net/bonding/rte_eth_bond_pmd.c | 216 ++++++- drivers/net/bonding/rte_eth_bond_private.h | 12 + drivers/net/null/Makefile | 2 +- drivers/net/null/rte_eth_null.c | 148 ++++- drivers/net/null/rte_eth_null.h | 40 ++ drivers/net/null/rte_pmd_null_version.map | 7 + 10 files changed, 1150 insertions(+), 32 deletions(-) create mode 100644 app/test/test_link_bonding_rssconf.c create mode 100644 drivers/net/null/rte_eth_null.h -- 1.7.9.5 ^ permalink raw reply [flat|nested] 126+ messages in thread

It stores its own copies of settings i.e. RETA, RSS hash function and RSS key. It’s required to ensure consistency. 1) RSS hash function set for bonding device is maximal set of RSS hash functions supported by all bonded devices. That mean, to have RSS support for bonding, all slaves should be RSS-capable. 2) RSS key is propagated over the slaves "as is". 3) RETA for bonding is an internal table managed by bonding API, and is used as a pattern to set up slaves. Its size is GCD of all RETA sizes, so it can be easily used as a pattern providing expected behavior, even if slaves RETA sizes are different.

Hi MichalX, I've checked above patches. But I am sorry that I am not a correct person to ack your patches. To review it correctly, at least knowledge about RSS and bonding PMD are needed, but honestly I am not familiar with RSS. Is it possible to find a correct person who can ack it? BTW, I've checked the patch from the following point of view. It may help other reviewers. (I've checked after fixing null PMD issues I've found today, please check an email I've sent to Tomasz) - No fatal errors are reported by checkpatch.pl. - Some style warnings are reported, but I guess we can ignore it. - No compile error with gcc-4.6/4.7/4.8/4.9/5, clang and icc. - No missing symbol. - No compile error for docs. - No compile error for examples.

This mode is intended to provide RSS configuration as known from "dynamic RSS configuration for one port" and made slaves transparent for client application implementation. 2) If .rxmode.mq_mode for bonding device isn't ETH_MQ_RX_RSS, slaves are not synchronized. That provides an ability to configure them manually. This mode may be useful when application wants to manage RSS in an unusual way and the consistency of RSS configuration for slaves isn't required. Turning on/off RSS mode for slaves when bonding is started is not possible. Other RSS configuration is propagated over slaves, when bonding device API is used to do it. v6 changes: - patchset reordered - fixed forward dependency between patch 4/9 and 5/9 v5 changes: - updated to DPDK 2.2 - removed copyright change from null device source - removed queue_stats_mapping_set from eth_dev_ops of bonding device - null pmd cleanups (removed unnecessary malloc, replaced memcpy with rte_memcpy) - fixed queues number configuration in null pmd v4 changes: - fixed copy-paste error, - removed example application as too complex and introducing a new dependency, - addapted null pmd to be used as testing device for dynamic RSS configuration, - addapted test units to use null pmd instead of ring pmd, - ring pmd is not used and changed in this patchset v3 changes: - checkpatch cleanups v2 changes: - added support for keys other than 40 bytes long, - now, if RSS key is not set for bonding, it is not set also for slaves, - fix - full initial RSS configuration before any slave is added was not possible due to the initially zeroed flow_type_rss_offloads for bonding, - fix - changed error to warning when slave is synchronizing due to the bonding's initial configuration (to allow use slaves' drivers not supporting dynamic RSS configuration in bonding), - some code cleanups, - updated documentation, Tomasz Kulasek (9): bonding: rss dynamic configuration null: fix segfault when null_pmd added to bonding null: extend number of virtual queues null: export eth_dev_null_create null: virtual dynamic rss configuration test: dynamic rss configuration bonding: per queue stats doc: fixed spellings and typos doc: dynamic rss configuration for bonding app/test/Makefile | 8 + app/test/test_link_bonding_rssconf.c | 679 ++++++++++++++++++++ .../prog_guide/link_bonding_poll_mode_drv_lib.rst | 42 +- drivers/net/bonding/rte_eth_bond_api.c | 28 + drivers/net/bonding/rte_eth_bond_pmd.c | 216 ++++++- drivers/net/bonding/rte_eth_bond_private.h | 12 + drivers/net/null/Makefile | 2 +- drivers/net/null/rte_eth_null.c | 149 ++++- drivers/net/null/rte_eth_null.h | 40 ++ drivers/net/null/rte_pmd_null_version.map | 7 + 10 files changed, 1151 insertions(+), 32 deletions(-) create mode 100644 app/test/test_link_bonding_rssconf.c create mode 100644 drivers/net/null/rte_eth_null.h -- 1.7.9.5 ^ permalink raw reply [flat|nested] 126+ messages in thread

It stores its own copies of settings i.e. RETA, RSS hash function and RSS key. It’s required to ensure consistency. 1) RSS hash function set for bonding device is maximal set of RSS hash functions supported by all bonded devices. That mean, to have RSS support for bonding, all slaves should be RSS-capable. 2) RSS key is propagated over the slaves "as is". 3) RETA for bonding is an internal table managed by bonding API, and is used as a pattern to set up slaves. Its size is GCD of all RETA sizes, so it can be easily used as a pattern providing expected behavior, even if slaves RETA sizes are different.

It stores its own copies of settings i.e. RETA, RSS hash function and RSS key. It’s required to ensure consistency. 1) RSS hash function set for bonding device is maximal set of RSS hash functions supported by all bonded devices. That mean, to have RSS support for bonding, all slaves should be RSS-capable. 2) RSS key is propagated over the slaves "as is". 3) RETA for bonding is an internal table managed by bonding API, and is used as a pattern to set up slaves. Its size is GCD of all RETA sizes, so it can be easily used as a pattern providing expected behavior, even if slaves RETA sizes are different.
