Merge branch 'sarx5-VCAP-debugfs'
netdev.vger.kernel.org archive mirror Steen Hegelund says:
==================== net: Add support for VCAP debugFS in Sparx5
This provides support for getting VCAP instance, VCAP rule and VCAP port keyset configuration information via the debug file system.
It builds on top of the initial IS2 VCAP support found in these series:
https://lore.kernel.org/all/20221020130904.1215072-1-steen.hegelund@microchip.com/ https://lore.kernel.org/all/20221109114116.3612477-1-steen.hegelund@microchip.com/ https://lore.kernel.org/all/20221111130519.1459549-1-steen.hegelund@microchip.com/
Functionality: ==============
The VCAP API exposes a /sys/kernel/debug/sparx5/vcaps folder containing the following entries:
- raw_<vcap>_<instance> This is a raw dump of the VCAP instance with a line for each available VCAP rule. This information is limited to the VCAP rule address, the rule size and the rule keyset name as this requires very little information from the VCAP cache.
This can be used to detect if a valid rule is stored at the correct address.
- <vcap>_<instance> This dumps the VCAP instance configuration: address ranges, chain id ranges, word size of keys and actions etc, and for each VCAP rule the details of keys (values and masks) and actions are shown.
This is useful when discovering if the expected rule is present and in which order it will be matched.
- <interface> This shows the keyset configuration per lookup and traffic type and the set of sticky bits (common for all interfaces). This is cleared when shown, so it is possible to sample over a period of time.
It also shows if this port/lookup is enabled for matching in the VCAP.
This can be used to find out which keyset the traffic being sent to a port, will be matched against, and if such traffic has been seen by one of the ports.
Delivery: =========
This is current plan for delivering the full VCAP feature set of Sparx5:
- TC protocol all support for IS2 VCAP - Sparx5 IS0 VCAP support - TC policer and drop action support (depends on the Sparx5 QoS support upstreamed separately) - Sparx5 ES0 VCAP support - TC flower template support - TC matchall filter support for mirroring and policing ports - TC flower filter mirror action support - Sparx5 ES2 VCAP support
Version History: ================ v2 Removed a 'support' folder (used for integration testing) that had been added in patch 6/8 by a mistake. Wrapped long lines.
v1 Initial version ====================

Merge branch 'sparx5-IS2-VCAP'
Steen Hegelund says:
==================== Add support for Sparx5 IS2 VCAP
This provides initial support for the Sparx5 VCAP functionality via the 'tc' traffic control userspace tool and its flower filter.
Overview: =========
The supported flower filter keys and actions are:
- source and destination MAC address keys - trap action - pass action
The supported Sparx5 VCAPs are: IS2 (see below for more info)
The VCAP (Versatile Content-Aware Processor) feature is essentially a TCAM with rules consisting of:
- Programmable key fields - Programmable action fields - A counter (which may be only one bit wide)
Besides this each VCAP has:
- A number of independent lookups - A keyset configuration typically per port per lookup
VCAPs are used in many of the TSN features such as PSFP, PTP, FRER as well as the general shaping, policing and access control, so it is an important building block for these advanced features.
Functionality: ==============
When a frame is passed to a VCAP the VCAP will generate a set of keys (keyset) based on the traffic type. If there is a rule created with this keyset in the VCAP and the values of the keys matches the values in the keyset of the frame, the rule is said to match and the actions in the rule will be executed and the rule counter will be incremented. No more rules will be examined in this VCAP lookup.
If there is no match in the current lookup the frame will be matched against the next lookup (some VCAPs do the processing of the lookups in parallel).
The Sparx5 SoC has 6 different VCAP types:
- IS0: Ingress Stage 0 (AKA CLM) mostly handles classification - IS2: Ingress Stage 2 mostly handles access control - IP6PFX: IPv6 prefix: Provides tables for IPV6 address management - LPM: Longest Path Match for IP guarding and routing - ES0: Egress Stage 0 is mostly used for CPU copying and multicast handling - ES2: Egress Stage 2 is known as the rewriter and mostly updates tags
Design: =======
The VCAP implementation provides switchcore independent handling of rules and supports:
- Creating and deleting rules - Updating and getting rules
The platform specific API implementation as well as the platform specific model of the VCAP instances are attached to the VCAP API and a client can then access rules via the API in a platform independent way, with the limitations that each VCAP has in terms of is supported keys and actions.
The VCAP model is generated from information delivered by the designers of the VCAP hardware.
Here is an illustration of this:
+------------------+ +------------------+ | TC flower filter | | PTP client | | for Sparx5 | | for Sparx5 | +-------------\----+ +---------/--------+ \ / \ / \ / \ / \ / +----v--------v----+ | VCAP API | +---------|--------+ | | | | +---------v--------+ | VCAP control | | instance | +----/--------|----+ / | / | / | / | +--------------v---+ +----v-------------+ | Sparx5 VCAP | | Sparx5 VCAP API | | model | | Implementation | +------------------+ +---------|--------+ | | | | +---------v--------+ | Sparx5 VCAP HW | +------------------+
Delivery: =========
For now only the IS2 is supported but later the IS0, ES0 and ES2 will be added. There are currently no plans to support the IP6PFX and the LPM VCAPs.
The IS2 VCAP has 4 lookups and they are accessible with a TC chain id:
- chain 8000000: IS2 Lookup 0 - chain 8100000: IS2 Lookup 1 - chain 8200000: IS2 Lookup 2 - chain 8300000: IS2 Lookup 3
These lookups are executed in parallel by the IS2 VCAP but the actions are executed in series (the datasheet explains what happens if actions overlap).
The functionality of TC flower as well as TC matchall filters will be expanded in later submissions as well as the number of VCAPs supported.
This is current plan:
- add support for more TC flower filter keys and extend the Sparx5 port keyset configuration - support for TC protocol all - debugfs support for inspecting rules - TC flower filter statistics - Sparx5 IS0 VCAP support and more TC keys and actions to support this - add TC policer and drop action support (depends on the Sparx5 QoS support upstreamed separately) - Sparx5 ES0 VCAP support and more TC actions to support this - TC flower template support - TC matchall filter support for mirroring and policing ports - TC flower filter mirror action support - Sparx5 ES2 VCAP support
The LAN966x switchcore will also be updated to use the VCAP API as well as future Microchip switches. The LAN966x has 3 VCAPS (IS1, IS2 and ES0) and a slightly different keyset and actionset portfolio than Sparx5.
Version History: ================ v3 Moved the sparx5_tc_flower_set_exterr function to the VCAP API and renamed it. Moved the sparx5_netbytes_copy function to the VCAP_API and renamed it (thanks Horatiu Vultur). Fixed indentation in the vcap_write_rule function. Added a comment mentioning the typegroup table terminator in the vcap_iter_skip_tg function.
v2 Made the KUNIT test model a superset of the real model to fix a kernel robot build error.
v1 Initial version ====================
