This marks the initial phase of refactoring the ice rte_flow
implementation.
The combination of switch and fdir rules within the same syntax has led
to inconvenient user experiences. Naturally, the switch filter and fdir
filter represent distinct pipeline stages with differing hardware
capabilities.
To address this, we have made the decision to assign each stage to a
separate rte_flow group. This will allow users to clearly specify their
intentions when creating a rule. Consequently, the need for a pipeline
mode can be removed.

-- ``Generic Flow Pipeline Mode Support`` (default ``0``)
-
- In pipeline mode, a flow can be set at one specific stage by setting parameter
- ``priority``. Currently, we support two stages: priority = 0 or !0. Flows with
- priority 0 located at the first pipeline stage which typically be used as a firewall
- to drop the packet on a blocklist(we called it permission stage). At this stage,
- flow rules are created for the device's exact match engine: switch. Flows with priority
- !0 located at the second stage, typically packets are classified here and be steered to
- specific queue or queue group (we called it distribution stage), At this stage, flow
- rules are created for device's flow director engine.
- For none-pipeline mode, ``priority`` is ignored, a flow rule can be created as a flow director
- rule or a switch rule depends on its pattern/action and the resource allocation situation,
- all flows are virtually at the same pipeline stage.
- By default, generic flow API is enabled in none-pipeline mode, user can choose to
- use pipeline mode by setting ``devargs`` parameter ``pipeline-mode-support``,
- for example::
-
- -a 80:00.0,pipeline-mode-support=1
-
- ``Default MAC Disable`` (default ``0``)
Disable the default MAC make the device drop all packets by default,

From: Qi Zhang @ 2023-08-14 20:26 UTC (permalink / raw)
To: qiming.yang; +Cc: dev, Qi Zhang
Mapping rte_flow_attr->group to a specific hardware stage.
Group 0 -> switch filter
Group 1 -> acl filter
Group 2 -> fdir filter
For RSS, it will only be selected if there is a RTE_FLOW_ACTION_RSS
action target no queue group and the group ID is ignored.
Since each flow parser will be selected based on the group, there is no
need to maintain a separate 'parser list' or related APIs for
registering/unregistering parsers.

1. remove pipeline mode
2. apply group to hardware pipeline stage static mapping
v2:
- fix segment fault when an unintialized engine has been selected.

This marks the initial phase of refactoring the ice rte_flow
implementation.
The combination of switch and fdir rules within the same syntax has led
to inconvenient user experiences. Naturally, the switch filter and fdir
filter represent distinct pipeline stages with differing hardware
capabilities.
To address this, we have made the decision to assign each stage to a
separate rte_flow group. This will allow users to clearly specify their
intentions when creating a rule. Consequently, the need for a pipeline
mode can be removed.

-- ``Generic Flow Pipeline Mode Support`` (default ``0``)
-
- In pipeline mode, a flow can be set at one specific stage by setting parameter
- ``priority``. Currently, we support two stages: priority = 0 or !0. Flows with
- priority 0 located at the first pipeline stage which typically be used as a firewall
- to drop the packet on a blocklist(we called it permission stage). At this stage,
- flow rules are created for the device's exact match engine: switch. Flows with priority
- !0 located at the second stage, typically packets are classified here and be steered to
- specific queue or queue group (we called it distribution stage), At this stage, flow
- rules are created for device's flow director engine.
- For none-pipeline mode, ``priority`` is ignored, a flow rule can be created as a flow director
- rule or a switch rule depends on its pattern/action and the resource allocation situation,
- all flows are virtually at the same pipeline stage.
- By default, generic flow API is enabled in none-pipeline mode, user can choose to
- use pipeline mode by setting ``devargs`` parameter ``pipeline-mode-support``,
- for example::
-
- -a 80:00.0,pipeline-mode-support=1
-
- ``Default MAC Disable`` (default ``0``)
Disable the default MAC make the device drop all packets by default,

To: qiming.yang; +Cc: zhichaox.zeng, dev, Qi Zhang
Mapping rte_flow_attr->group to a specific hardware stage.
Group 0 -> switch filter
Group 1 -> acl filter
Group 2 -> fdir filter
For RSS, it will only be selected if there is a RTE_FLOW_ACTION_RSS
action target no queue group and the group ID is ignored.
Since each flow parser will be selected based on the group, there is no
need to maintain a separate 'parser list' or related APIs for
registering/unregistering parsers.

1. remove pipeline mode
2. apply group to hardware pipeline stage static mapping
3. add genenic flow document
v3:
- fix the issue when acl=off on dcf mode
- refine the disabled engine handling
- unified the supported pattern variable name
- add document
v2:
- fix segment fault when an unintialized engine has been selected.
Qi Zhang (5):
net/ice: remove pipeline mode
net/ice: refine flow engine disabling
net/ice: map group to pipeline stage
net/ice: refine supported flow pattern name
doc: add generic flow doc for ice PMD

This marks the initial phase of refactoring the ice rte_flow
implementation.
The combination of switch and fdir rules within the same syntax has led
to inconvenient user experiences. Naturally, the switch filter and fdir
filter represent distinct pipeline stages with differing hardware
capabilities.
To address this, we have made the decision to assign each stage to a
separate rte_flow group. This will allow users to clearly specify their
intentions when creating a rule. Consequently, the need for a pipeline
mode can be removed.

-- ``Generic Flow Pipeline Mode Support`` (default ``0``)
-
- In pipeline mode, a flow can be set at one specific stage by setting parameter
- ``priority``. Currently, we support two stages: priority = 0 or !0. Flows with
- priority 0 located at the first pipeline stage which typically be used as a firewall
- to drop the packet on a blocklist(we called it permission stage). At this stage,
- flow rules are created for the device's exact match engine: switch. Flows with priority
- !0 located at the second stage, typically packets are classified here and be steered to
- specific queue or queue group (we called it distribution stage), At this stage, flow
- rules are created for device's flow director engine.
- For none-pipeline mode, ``priority`` is ignored, a flow rule can be created as a flow director
- rule or a switch rule depends on its pattern/action and the resource allocation situation,
- all flows are virtually at the same pipeline stage.
- By default, generic flow API is enabled in none-pipeline mode, user can choose to
- use pipeline mode by setting ``devargs`` parameter ``pipeline-mode-support``,
- for example::
-
- -a 80:00.0,pipeline-mode-support=1
-
- ``Default MAC Disable`` (default ``0``)
Disable the default MAC make the device drop all packets by default,

Only use "disable_engine_mask" for flow engine disabling
In PF mode, only ACL engine will be disabled.
In DCF mode, FDIR and HASH engine will be disabled.
In DCF mode with "acl=off", ACL engine will also be
disabled.

Mapping rte_flow_attr->group to a specific hardware stage.
Group 0 -> switch filter
Group 1 -> acl filter (dcf mode only)
Group 2 -> fdir filter (pf mode only)
For RSS, it will only be selected if there is a RTE_FLOW_ACTION_RSS
action target no queue group and the group ID is ignored.
Since each flow parser will be selected based on the group, there is no
need to maintain a separate 'parser list' or related APIs for
registering/unregistering parsers.

send AdminQ commands that it would like to execute over to the PF and receive
responses for the same from PF.
+Generic Flow Support
+~~~~~~~~~~~~~~~~~~~~
+
+The ice PMD provides support for the Generic Flow API (RTE_FLOW), enabling
+users to offload various flow classification tasks to the E810 NIC.
+The E810 NIC's packet processing pipeline consists of the following stages:
+
+Switch: Supports exact match and limited wildcard matching with a large flow
+capacity.
+
+ACL: Supports wildcard matching with a smaller flow capacity (DCF mode only).
+
+FDIR: Supports exact match with a large flow capacity (PF mode only).
+
+Hash: Supports RSS (PF mode only)
+
+The ice PMD utilizes the ice_flow_engine structure to represent each of these
+stages and leverages the rte_flow rule's ``group`` attribute for selecting the
+appropriate engine for Switch, ACL, and FDIR operations:
+
+Group 0 maps to Switch
+Group 1 maps to ACL
+Group 2 maps to FDIR
+
+In the case of RSS, it will only be selected if a ``RTE_FLOW_ACTION_RSS`` action
+is targeted to no queue group, and the group attribute is ignored.
+
+For each engine, a list of supported patterns is maintained in a global array
+named ``ice_<engine>_supported_pattern``. The Ice PMD will reject any rule with
+a pattern that is not included in the supported list.
+
+One notable feature is the ice PMD's ability to leverage the Raw pattern,
+enabling protocol-agnostic flow offloading. Here is an example of creating
+a rule that matches an IPv4 destination address of 1.2.3.4 and redirects it to
+queue 3 using a raw pattern:
+
+flow create 0 ingress group 2 pattern raw \
+pattern spec \
+00000000000000000000000008004500001400004000401000000000000001020304 \
+pattern mask \
+000000000000000000000000000000000000000000000000000000000000ffffffff \
+end actions queue index 3 / mark id 3 / end
+
+Currently, raw pattern support is limited to the FDIR and Hash engines.

This marks the initial phase of refactoring the ice rte_flow
implementation.
The combination of switch and fdir rules within the same syntax has led
to inconvenient user experiences. Naturally, the switch filter and fdir
filter represent distinct pipeline stages with differing hardware
capabilities.
To address this, we have made the decision to assign each stage to a
separate rte_flow group. This will allow users to clearly specify their
intentions when creating a rule. Consequently, the need for a pipeline
mode can be removed.

-
- In pipeline mode, a flow can be set at one specific stage by setting parameter
- ``priority``. Currently, we support two stages: priority = 0 or !0. Flows with
- priority 0 located at the first pipeline stage which typically be used as a firewall
- to drop the packet on a blocklist(we called it permission stage). At this stage,
- flow rules are created for the device's exact match engine: switch. Flows with priority
- !0 located at the second stage, typically packets are classified here and be steered to
- specific queue or queue group (we called it distribution stage), At this stage, flow
- rules are created for device's flow director engine.
- For none-pipeline mode, ``priority`` is ignored, a flow rule can be created as a flow director
- rule or a switch rule depends on its pattern/action and the resource allocation situation,
- all flows are virtually at the same pipeline stage.
- By default, generic flow API is enabled in none-pipeline mode, user can choose to
- use pipeline mode by setting ``devargs`` parameter ``pipeline-mode-support``,
- for example::
-
- -a 80:00.0,pipeline-mode-support=1
-
- ``Default MAC Disable`` (default ``0``)

Only "disable_engine_mask" for flow engine disabling
In PF mode, only ACL engine will be disabled.
In DCF mode, FDIR and HASH engine will be disabled.
In DCF mode with "acl=off", ACL engine will also be
disabled.

Mapping rte_flow_attr->group to a specific hardware stage.
Group 0 -> switch filter
Group 1 -> acl filter (dcf mode only)
Group 2 -> fdir filter (pf mode only)
For RSS, it will only be selected if there is a RTE_FLOW_ACTION_RSS
action target no queue group and the group ID is ignored.
Since each flow parser will be selected based on the group, there is no
need to maintain a separate 'parser list' or related APIs for
registering/unregistering parsers.

send AdminQ commands that it would like to execute over to the PF and receive
responses for the same from PF.
+Generic Flow Support
+~~~~~~~~~~~~~~~~~~~~
+
+The ice PMD provides support for the Generic Flow API (RTE_FLOW), enabling
+users to offload various flow classification tasks to the E810 NIC.
+The E810 NIC's packet processing pipeline consists of the following stages:
+
+Switch: Supports exact match and limited wildcard matching with a large flow
+capacity.
+
+ACL: Supports wildcard matching with a smaller flow capacity (DCF mode only).
+
+FDIR: Supports exact match with a large flow capacity (PF mode only).
+
+Hash: Supports RSS (PF mode only)
+
+The ice PMD utilizes the ice_flow_engine structure to represent each of these
+stages and leverages the rte_flow rule's ``group`` attribute for selecting the
+appropriate engine for Switch, ACL, and FDIR operations:
+
+Group 0 maps to Switch
+Group 1 maps to ACL
+Group 2 maps to FDIR
+
+In the case of RSS, it will only be selected if a ``RTE_FLOW_ACTION_RSS`` action
+is targeted to no queue group, and the group attribute is ignored.
+
+For each engine, a list of supported patterns is maintained in a global array
+named ``ice_<engine>_supported_pattern``. The Ice PMD will reject any rule with
+a pattern that is not included in the supported list.
+
+One notable feature is the ice PMD's ability to leverage the Raw pattern,
+enabling protocol-agnostic flow offloading. Here is an example of creating
+a rule that matches an IPv4 destination address of 1.2.3.4 and redirects it to
+queue 3 using a raw pattern:
+
+flow create 0 ingress group 2 pattern raw \
+pattern spec \
+00000000000000000000000008004500001400004000401000000000000001020304 \
+pattern mask \
+000000000000000000000000000000000000000000000000000000000000ffffffff \
+end actions queue index 3 / mark id 3 / end
+
+Currently, raw pattern support is limited to the FDIR and Hash engines.

1. remove pipeline mode
2. apply group to hardware pipeline stage static mapping
3. add genenic flow document
v5:
- remove incorrect group attr check in ice_flow_valid_attr
v4:
- fix error handling when target engine was disabled.
v3:
- fix the issue when acl=off on dcf mode
- refine the disabled engine handling
- unified the supported pattern variable name
- add document
v2:
- fix segment fault when an uninitialized engine has been selected.
Qi Zhang (5):

This marks the initial phase of refactoring the ice rte_flow
implementation.
The combination of switch and fdir rules within the same syntax has led
to inconvenient user experiences. Naturally, the switch filter and fdir
filter represent distinct pipeline stages with differing hardware
capabilities.
To address this, we have made the decision to assign each stage to a
separate rte_flow group. This will allow users to clearly specify their
intentions when creating a rule. Consequently, the need for a pipeline
mode can be removed.

-
- In pipeline mode, a flow can be set at one specific stage by setting parameter
- ``priority``. Currently, we support two stages: priority = 0 or !0. Flows with
- priority 0 located at the first pipeline stage which typically be used as a firewall
- to drop the packet on a blocklist(we called it permission stage). At this stage,
- flow rules are created for the device's exact match engine: switch. Flows with priority
- !0 located at the second stage, typically packets are classified here and be steered to
- specific queue or queue group (we called it distribution stage), At this stage, flow
- rules are created for device's flow director engine.
- For none-pipeline mode, ``priority`` is ignored, a flow rule can be created as a flow director
- rule or a switch rule depends on its pattern/action and the resource allocation situation,
- all flows are virtually at the same pipeline stage.
- By default, generic flow API is enabled in none-pipeline mode, user can choose to
- use pipeline mode by setting ``devargs`` parameter ``pipeline-mode-support``,
- for example::
-
- -a 80:00.0,pipeline-mode-support=1
-
- ``Default MAC Disable`` (default ``0``)
Disable the default MAC make the device drop all packets by default,

Only "disable_engine_mask" for flow engine disabling
In PF mode, only ACL engine will be disabled.
In DCF mode, FDIR and HASH engine will be disabled.
In DCF mode with "acl=off", ACL engine will also be
disabled.

Mapping rte_flow_attr->group to a specific hardware stage.
Group 0 -> switch filter
Group 1 -> acl filter (dcf mode only)
Group 2 -> fdir filter (pf mode only)
For RSS, it will only be selected if there is a RTE_FLOW_ACTION_RSS
action target no queue group and the group ID is ignored.
Since each flow parser will be selected based on the group, there is no
need to maintain a separate 'parser list' or related APIs for
registering/unregistering parsers.

send AdminQ commands that it would like to execute over to the PF and receive
responses for the same from PF.
+Generic Flow Support
+~~~~~~~~~~~~~~~~~~~~
+
+The ice PMD provides support for the Generic Flow API (RTE_FLOW), enabling
+users to offload various flow classification tasks to the E810 NIC.
+The E810 NIC's packet processing pipeline consists of the following stages:
+
+Switch: Supports exact match and limited wildcard matching with a large flow
+capacity.
+
+ACL: Supports wildcard matching with a smaller flow capacity (DCF mode only).
+
+FDIR: Supports exact match with a large flow capacity (PF mode only).
+
+Hash: Supports RSS (PF mode only)
+
+The ice PMD utilizes the ice_flow_engine structure to represent each of these
+stages and leverages the rte_flow rule's ``group`` attribute for selecting the
+appropriate engine for Switch, ACL, and FDIR operations:
+
+Group 0 maps to Switch
+Group 1 maps to ACL
+Group 2 maps to FDIR
+
+In the case of RSS, it will only be selected if a ``RTE_FLOW_ACTION_RSS`` action
+is targeted to no queue group, and the group attribute is ignored.
+
+For each engine, a list of supported patterns is maintained in a global array
+named ``ice_<engine>_supported_pattern``. The Ice PMD will reject any rule with
+a pattern that is not included in the supported list.
+
+One notable feature is the ice PMD's ability to leverage the Raw pattern,
+enabling protocol-agnostic flow offloading. Here is an example of creating
+a rule that matches an IPv4 destination address of 1.2.3.4 and redirects it to
+queue 3 using a raw pattern:
+
+flow create 0 ingress group 2 pattern raw \
+pattern spec \
+00000000000000000000000008004500001400004000401000000000000001020304 \
+pattern mask \
+000000000000000000000000000000000000000000000000000000000000ffffffff \
+end actions queue index 3 / mark id 3 / end
+
+Currently, raw pattern support is limited to the FDIR and Hash engines.

Why not choosing the right engine automatically?
You are defining an API (group number specialization)
which is specific to this driver.
Don't you care about portability of DPDK applications?

OK, let me know if my understanding is correct or not.
I think the implementation somehow broken below description in rte_flow document.
"Groups are not linked by default, so the logical hierarchy of groups must be explicitly defined by flow rules themselves in each group using the JUMP action to define the next group to redirect to. "
Could a fix like below works ? Or any better suggestion?
1. Initially, map the switch to group 0, as it represents the first stage in the hardware pipeline.
2. For ACL usage, users should create a rule in group 0 with a JUMP action that includes an arbitrarily group ID. then, the driver will associate this group with ACL engine.
3. For FDIR usage, users should create a rule within group <ACL> with a JUMP action, utilizing a distinct group ID. then, the driver will link this group with FDIR engine.
Thanks
Qi
