The X values could vary, but are typically "soc@0/1e40000.ipa". What: .../XXXXXXX.ipa/version Date: June 2021 KernelVersion: v5.14 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/version file contains the IPA hardware version, as a period-separated set of two or three integers (e.g., "3.5.1" or "4.2"). What: .../XXXXXXX.ipa/feature/ Date: June 2021 KernelVersion: v5.14 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/feature/ directory contains a set of attributes describing features implemented by the IPA hardware. What: .../XXXXXXX.ipa/feature/rx_offload Date: June 2021 KernelVersion: v5.14 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/feature/rx_offload file contains a string indicating the type of receive checksum offload that is supported by the hardware. The possible values are "MAPv4" or "MAPv5". What: .../XXXXXXX.ipa/feature/tx_offload Date: June 2021 KernelVersion: v5.14 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/feature/tx_offload file contains a string indicating the type of transmit checksum offload that is supported by the hardware. The possible values are "MAPv4" or "MAPv5". What: .../XXXXXXX.ipa/endpoint_id/ Date: July 2022 KernelVersion: v5.19 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/endpoint_id/ directory contains attributes that define IDs associated with IPA endpoints. The "rx" or "tx" in an endpoint name is from the perspective of the AP. An endpoint ID is a small unsigned integer. What: .../XXXXXXX.ipa/endpoint_id/modem_rx Date: July 2022 KernelVersion: v5.19 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/endpoint_id/modem_rx file contains the ID of the AP endpoint on which packets originating from the embedded modem are received. What: .../XXXXXXX.ipa/endpoint_id/modem_tx Date: July 2022 KernelVersion: v5.19 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/endpoint_id/modem_tx file contains the ID of the AP endpoint on which packets destined for the embedded modem are sent. What: .../XXXXXXX.ipa/endpoint_id/monitor_rx Date: July 2022 KernelVersion: v5.19 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/endpoint_id/monitor_rx file contains the ID of the AP endpoint on which IPA "monitor" data is received. The monitor endpoint supplies replicas of packets that enter the IPA hardware for processing. Each replicated packet is preceded by a fixed-size "ODL" header (see .../XXXXXXX.ipa/feature/monitor, above). Large packets are truncated, to reduce the bandwidth required to provide the monitor function. What: .../XXXXXXX.ipa/modem/ Date: June 2021 KernelVersion: v5.14 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/modem/ directory contains attributes describing properties of the modem embedded in the SoC. What: .../XXXXXXX.ipa/modem/rx_endpoint_id Date: June 2021 KernelVersion: v5.14 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/modem/rx_endpoint_id file duplicates the value found in .../XXXXXXX.ipa/endpoint_id/modem_rx. What: .../XXXXXXX.ipa/modem/tx_endpoint_id Date: June 2021 KernelVersion: v5.14 Contact: Alex Elder <elder@kernel.org> Description: The .../XXXXXXX.ipa/modem/tx_endpoint_id file duplicates the value found in .../XXXXXXX.ipa/endpoint_id/modem_tx. |
