[dpdk-dev,v6,07/16] ethdev: flatten RSS configuration in flow API
Checks
Commit Message
Since its inception, the rte_flow RSS action has been relying in part on
external struct rte_eth_rss_conf for compatibility with the legacy RSS API.
This structure lacks parameters such as the hash algorithm to use, and more
recently, a method to tell which layer RSS should be performed on [1].
Given struct rte_eth_rss_conf will never be flexible enough to represent a
complete RSS configuration (e.g. RETA table), this patch supersedes it by
extending the rte_flow RSS action directly.
A subsequent patch will add a field to use a non-default RSS hash
algorithm. To that end, a field named "types" replaces the field formerly
known as "rss_hf" and standing for "RSS hash functions" as it was
confusing. Actual RSS hash function types are defined by enum
rte_eth_hash_function.
This patch updates all PMDs and example applications accordingly.
It breaks ABI compatibility for the following public functions:
- rte_flow_copy()
- rte_flow_create()
- rte_flow_query()
- rte_flow_validate()

v6 changes:
- Fixed QUEUE action support in mlx5 according to Nelio's comment [1].
This action relies on RSS to work and even though it targets a single Rx
queue, a non-NULL hash key is required.
- Updated API and ABI changes sections in release notes.
[1] http://dpdk.org/ml/archives/dev/2018-April/098635.html
v3 changes:
Documentation update regarding the meaning of a 0 value for RSS types in
flow rules.
It used to implicitly mean "no RSS" but is redefined as requesting a kind
of "best-effort" mode from PMDs, i.e. anything ranging from empty to
all-inclusive RSS; what matters is it provides safe defaults that will work
regardless of PMD capabilities.

Hi，Adrien Mazarguil
We have just use new RC.1 code on the feature of flow RSS API, but we find some abnormal phenomenon.
After that I check code again, I find that it is introduced in this patch:
SHA-1: ac8d22de2394e03ba4a77d8fd24381147aafb1d3
* ethdev: flatten RSS configuration in flow API
Signed-off-by: Adrien Mazarguil <adrien.mazarguil@6wind.com>
This abnormal phenomenon include i40e and ixgbe 2 NIC, it do not has these 2 bug before merge this patch.
It is first find out by yuan.peng@intel.com, she can tell you how to reappear these abnormal phenomenon on RSS flow API.
Thank you.

Hi，Adrien Mazarguil
There is a bug present with 18.05-rci when I test the feature "Move RSS to rte_flow" in i40e NIC
The test steps are as below:
./usertools/dpdk-devbind.py -b igb_uio 05:00.0 05:00.1
./x86_64-native-linuxapp-gcc/app/testpmd -c 0x1fffe -n 4 -- -i --nb-cores=8 --rxq=8 --txq=8 --port-topology=chained
testpmd> set fwd rxonly
Set rxonly packet forwarding mode
testpmd> set verbose 1
Change verbose level from 0 to 1
testpmd> start
testpmd> flow create 0 ingress pattern end actions rss queues 0 4 7 end / end
Caught error type 16 (specific action): cause: 0x7fff84e33658, RSS hash key too large
The rss rule can be set successfully when I test it yesterday with older dpdk version without this patch.
The NIC information is:
driver: i40e
version: 2.4.3
firmware-version: 6.01 0x80003205 1.1691.0
There is another problem with ixgbe nic:
./usertools/dpdk-devbind.py -b igb_uio 07:00.0 07:00.1
./x86_64-native-linuxapp-gcc/app/testpmd -c 0x1fffe -n 4 -- -i --nb-cores=8 --rxq=8 --txq=8 --disable-rss --port-topology=chained
testpmd> flow create 0 ingress pattern end actions rss queues 5 6 7 end / end
Caught error type 2 (flow rule (handle)): Failed to create flow.
The rule setting command can be executed successfully with older dpdk version.
Could you help to check if there is a relationship between the bugs and this patch?
Thank you.
Yuan.

Subject: RE: [dpdk-dev] [PATCH v6 07/16] ethdev: flatten RSS configuration in flow API
Hi，Adrien Mazarguil
We have just use new RC.1 code on the feature of flow RSS API, but we find some abnormal phenomenon.
After that I check code again, I find that it is introduced in this patch:
SHA-1: ac8d22de2394e03ba4a77d8fd24381147aafb1d3
* ethdev: flatten RSS configuration in flow API
Signed-off-by: Adrien Mazarguil <adrien.mazarguil@6wind.com>
This abnormal phenomenon include i40e and ixgbe 2 NIC, it do not has these 2 bug before merge this patch.
It is first find out by yuan.peng@intel.com, she can tell you how to reappear these abnormal phenomenon on RSS flow API.
Thank you.

> Since its inception, the rte_flow RSS action has been relying in part on

> This structure lacks parameters such as the hash algorithm to use, and more

> confusing. Actual RSS hash function types are defined by enum
> rte_eth_hash_function.
>
> This patch updates all PMDs and example applications accordingly.

> It breaks ABI compatibility for the following public functions:

> - rte_flow_create()

Hi，Adrien Mazarguil
There is a bug of queue region with 18.05-rc1
The test steps are as below:
./usertools/dpdk-devbind.py -b igb_uio 05:00.0
./x86_64-native-linuxapp-gcc/app/testpmd -c 1ffff -n 4 -- -i --rxq=16 --txq=16
testpmd> port config all rss all
Configuration of RSS hash at ethernet port 0 failed with error (22): Invalid argument.
testpmd> set fwd rxonly
testpmd> set verbose 1
testpmd> start
testpmd> set port 0 queue-region region_id 0 queue_start_index 1 queue_num 1
testpmd> set port 0 queue-region region_id 0 flowtype 31
testpmd> set port 0 queue-region flush on
testpmd> port 0/queue 0: received 1 packets
src=00:13:3B:0C:21:95 - dst=00:00:00:00:01:00 - type=0x0800 - length=90 - nb_segs=1 - hw ptype: L2_ETHER L3_IPV4_EXT_UNKNOWN L4_UDP - sw ptype: L2_ETHER L3_IPV4 L4_UDP - l2_len=14 - l3_len=20 - l4_len=8 - Receive queue=0x0
ol_flags: PKT_RX_L4_CKSUM_GOOD PKT_RX_IP_CKSUM_GOOD
the packet should be distributed to queue 1 instead of queue0. And the command" port config all rss all" failed to execute.
Could you help to check if this has relationship with your patches relevant to flow api?
Thanks.
Yuan.

Subject: Re: [dpdk-dev] [PATCH v6 07/16] ethdev: flatten RSS configuration in flow API
Hi，Adrien Mazarguil
There is a bug present with 18.05-rci when I test the feature "Move RSS to rte_flow" in i40e NIC
The test steps are as below:
./usertools/dpdk-devbind.py -b igb_uio 05:00.0 05:00.1
./x86_64-native-linuxapp-gcc/app/testpmd -c 0x1fffe -n 4 -- -i --nb-cores=8 --rxq=8 --txq=8 --port-topology=chained
testpmd> set fwd rxonly
Set rxonly packet forwarding mode
testpmd> set verbose 1
Change verbose level from 0 to 1
testpmd> start
testpmd> flow create 0 ingress pattern end actions rss queues 0 4 7 end / end
Caught error type 16 (specific action): cause: 0x7fff84e33658, RSS hash key too large
The rss rule can be set successfully when I test it yesterday with older dpdk version without this patch.
The NIC information is:
driver: i40e
version: 2.4.3
firmware-version: 6.01 0x80003205 1.1691.0
There is another problem with ixgbe nic:
./usertools/dpdk-devbind.py -b igb_uio 07:00.0 07:00.1
./x86_64-native-linuxapp-gcc/app/testpmd -c 0x1fffe -n 4 -- -i --nb-cores=8 --rxq=8 --txq=8 --disable-rss --port-topology=chained
testpmd> flow create 0 ingress pattern end actions rss queues 5 6 7 end / end
Caught error type 2 (flow rule (handle)): Failed to create flow.
The rule setting command can be executed successfully with older dpdk version.
Could you help to check if there is a relationship between the bugs and this patch?
Thank you.
Yuan.

Hi，Adrien Mazarguil
We have just use new RC.1 code on the feature of flow RSS API, but we find some abnormal phenomenon.
After that I check code again, I find that it is introduced in this patch:
SHA-1: ac8d22de2394e03ba4a77d8fd24381147aafb1d3
* ethdev: flatten RSS configuration in flow API
Signed-off-by: Adrien Mazarguil <adrien.mazarguil@6wind.com>
This abnormal phenomenon include i40e and ixgbe 2 NIC, it do not has these 2 bug before merge this patch.
It is first find out by yuan.peng@intel.com, she can tell you how to reappear these abnormal phenomenon on RSS flow API.
Thank you.

Hi Peng Yuan,
Apologies for the delay, I'll answer below to the entire thread.

I assume this issue is related rte_eth_dev_configure() which was recently
fixed [1], right?

Regarding this issue, the testpmd flow command now requests hash key length
from the PMD by default [2] if left unspecified by user. This value is taken
from the "hash_key_size" field returned by rte_eth_dev_infos_get().
While most PMDs return 40 here, i40e returns:
(I40E_PFQF_HKEY_MAX_INDEX + 1) * sizeof(uint32_t)
/* that is, (12 + 1) * 4 => 52 */
Is this correct and really supported by i40e? Otherwise I'd suggest to fix
the PMD as it may also confuse applications other than testpmd.
Note that you should be able to revert to the old behavior with the
PMD-specific default key by specifying a "key_len 0" parameter to the RSS
action.

Perhaps a similar issue since testpmd now provides default values for
unspecified fields of the RSS action, that is, a default hash key with a
PMD-returned default length and the global "rss_hf" value for types (here 0
due to --disable-rss).
Try appending the following arguments to the RSS action:
key_len 0 types ip udp end
If it works, it probably means the issue was always present, it just never
showed up due to the inability to validate RSS action parameters
previously. You should make sure ixgbe supports them.

This is the root cause for this issue, although i40 return :
dev_info->hash_key_size = (I40E_PFQF_HKEY_MAX_INDEX + 1) *
sizeof(uint32_t);
that is 52 byte, but " RTE_DIM(rss_config->key)" ， which is
uint8_t key[(I40E_VFQF_HKEY_MAX_INDEX > I40E_PFQF_HKEY_MAX_INDEX ?
I40E_VFQF_HKEY_MAX_INDEX : I40E_PFQF_HKEY_MAX_INDEX) + 1 *
sizeof(uint32_t)]; /* Hash key. */
is not 52!!!
I think the code should be :
uint8_t key[(I40E_VFQF_HKEY_MAX_INDEX > I40E_PFQF_HKEY_MAX_INDEX ?
I40E_VFQF_HKEY_MAX_INDEX : I40E_PFQF_HKEY_MAX_INDEX + 1) *
sizeof(uint32_t)]; /* Hash key. */
If you agree and permit, I WILL commit a patch to fix this bug.

No comment regarding ixgbe?
Hi Adrien,
The third problem which use ixgbe NIC:
I add " key_len 0 types ip udp end " to the command "flow create 0 ingress pattern end actions rss queues 5 6 7 end / end"
It shows:
testpmd> flow create 0 ingress pattern end actions rss queues 5 6 7 end / key_len 0 types ip udp end / end
Bad arguments
testpmd> flow create 0 ingress pattern end actions rss queues 5 6 7 / key_len 0 types ip udp end / end
Bad arguments
testpmd> key_len 0 types ip udp end
Command not found
Could you show me the correct command?
Thanks.
Yuan.

Hi Adrien,
I configure the command as:
testpmd> flow create 0 ingress pattern end actions rss types udp end queues 5 end / end
Flow rule #0 created
The rule can be set successfully.
It seems like you have added several parameter to the feature, and modified the command format.
testpmd> flow create 0 ingress pattern end actions rss
func [TOKEN]: RSS hash function to apply
level [TOKEN]: encapsulation level for "types"
types [TOKEN]: specific RSS hash types
key [TOKEN]: RSS hash key
key_len [TOKEN]: RSS hash key length in bytes
queues [TOKEN]: queue indices to use
/ [TOKEN]: specify next action
Could you send me and Zhao Wei a user guideline?
Thank you.
Yuan.

This seems to be caused by new command input methord for rte_flow.
I have try " flow create 2 ingress pattern end actions rss types udp tcp end queues 5 6 7 end / end "
This can be input well. I have tell Peng yuan about this.
