2024-04-25net: sparx5: Correct spelling in commentsSimon Horman1-1/+1
Correct spelling in comments, as flagged by codespell. Signed-off-by: Simon Horman <horms@kernel.org> Reviewed-by: Daniel Machon <daniel.machon@microchip.com> Link: https://lore.kernel.org/r/20240424-lan743x-confirm-v2-4-f0480542e39f@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-01-18net: microchip: sparx5: Add VCAP admin locking in debugFSSteen Hegelund1-0/+3
This ensures that the admin lock is taken before the debugFS functions starts iterating the VCAP rules. It also adds a separate function to decode a rule, which expects the lock to have been taken before it is called. Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: David S.

2023-01-16net: microchip: vcap api: Enable/Disable rules via chains in VCAP HWSteen Hegelund1-0/+3
This supports that individual rules are enabled and disabled via chain information. This is done by keeping disabled rules in the VCAP list (cached) until they are enabled, and only at this time are the rules written to the VCAP HW.

2023-01-16net: microchip: vcap api: Add a storage state to a VCAP ruleSteen Hegelund1-2/+7
This allows a VCAP rule to be in one of 3 states: - permanently stored in the VCAP HW (for rules that must always be present) - enabled (stored in HW) when the corresponding lookup has been enabled - disabled (stored in SW) when the lookup is disabled This way important VCAP rules can be added even before the user enables the VCAP lookups using a TC matchall filter.

2022-12-06net: microchip: vcap: Add vcap_get_ruleHoratiu Vultur1-0/+14
Add function vcap_get_rule which returns a rule based on the internal rule id. The entire functionality of reading and decoding the rule from the VCAP was inside vcap_api_debugfs file. So move the entire implementation in vcap_api as this is used also by vcap_get_rule. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2022-11-25net: microchip: sparx5: Support for copying and modifying rules in the APISteen Hegelund1-4/+0
This adds support for making a copy of a rule and modify keys and actions to differentiate the copy. Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-11-21net: microchip: sparx5: Add VCAP debugFS key/action support for the VCAP APISteen Hegelund1-0/+16
This add support for displaying the keys and actions in a rule. The keys and action display format will be determined by the size and the type of the key or action. The longer keys will typically be displayed as a hexadecimal byte array. The actionset is not decoded in full as the Sparx5 IS2 only has one supported action, so this will be added later with other VCAP types.

2022-11-21net: microchip: sparx5: Add VCAP rule debugFS support for the VCAP APISteen Hegelund1-0/+14
This add support to show all rules in a VCAP instance. The information shown is: - rule id - address range - size - chain id - keyset name, subword size, register span - actionset name, subword size, register span - counter value - sticky bit (one bit width counter) Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: David S.

2022-11-21net: microchip: sparx5: Add raw VCAP debugFS support for the VCAP APISteen Hegelund1-0/+73
This adds support for decoding VCAP rules with a minimum number of attributes: address, rule size and keyset. This allows for a quick inspection of a VCAP instance to determine if the rule are present and in the correct order.
