* ltq-vdsl-app: Fix counter overflow resulting in negative valuesRoland Barenbrug2022-08-061-1/+1
| | | | | | | | | | | | | The re-transmit counters can overflow the 32 bit representation resulting in negative values being displayed. Background being that the numbers are treated at some point as signed INT rather than unsigned INT. Change the counters from 32 bit to 64 bit, should provide sufficient room to avoid any overflow. Not the nicest solution but it works Fixes: #10077 Signed-off-by: Roland Barenbrug <roland@treslong.com> Acked-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> (cherry picked from commit 456b9029d764e69f390ee26bca24883b12eb83c2)
* ltq-vdsl: move to the default device name /dev/dsl_cpe_api/0Andre Heider2022-01-081-1/+1
| | | | | | | This makes patching it for ltq-vdsl-app unnecessary and paves the way for VRX518 support. Signed-off-by: Andre Heider <a.heider@gmail.com>
* ltq-vdsl-app: add error vector counters to the ubus metricsAndre Heider2021-10-211-0/+23
| | | | | | | | | | | | | | | These are useful stats to debug vector related line deteriorations, see [0]. Example output: "erb": { "sent": 169925, "discarded": 0 } [0] https://forum.openwrt.org/t/vectoring-on-lantiq-vrx200-vr9-missing-callback-for-sending-error-samples/104046 Signed-off-by: Andre Heider <a.heider@gmail.com>
* ltq-vdsl-app: prepare for multiple mei ioctlsAndre Heider2021-10-211-18/+22
| | | | | | | | | | | | Refactor so that the outer function opens and closes the mei fd and passes it around, just as with the main fd. That also allows us to use the IOCTL macro in get_vector_status() and clean up accordingly. Switch to AUTORELEASE while at it. Signed-off-by: Andre Heider <a.heider@gmail.com>
* ltq-vdsl-app: extent dsl metrics with state_num and power_state_numFlorian Eckert2021-04-171-14/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the old ubus dsl API, the numbers for the individual line_states and power_states were also returned. These were not ported to the new DSL C-API. This commit adds the missing information. For this the internal values are mapped to numbers. * additional JSON output for state_num: "state_num": <map_state_number> Since not all values are meaningful only the following values are implemented, this can be extended if the future. * LSTATE_MAP_NOT_INITIALIZED * LSTATE_MAP_EXCEPTION * LSTATE_MAP_IDLE * LSTATE_MAP_SILENT * LSTATE_MAP_HANDSHAKE * LSTATE_MAP_FULL_INIT * LSTATE_MAP_SHOWTIME_NO_SYNC * LSTATE_MAP_SHOWTIME_TC_SYNC * LSTATE_MAP_RESYNC * additinal JSON output for power_level: "power_state_num": <map_power_satte_number>, Since there are not so many here, all are mapped. * PSTATE_MAP_NA, * PSTATE_MAP_L0, * PSTATE_MAP_L1, * PSTATE_MAP_L2, * PSTATE_MAP_L3, Signed-off-by: Florian Eckert <fe@dev.tdt.de> v6: Add state LSTATE_MAP_NOT_INITILIZED at the beginning of the list Start the list LSTATE_MAP with -1 Reviewed-by: Andre Heider <a.heider@gmail.com>
* lantiq: use ActualNetDataRate for speed reportingJeroen Peelaerts2021-04-031-0/+5
| | | | | | | | | | | | | Switch to Actual Net Data Rate (ACTNDR) for speed reporting on lantiq VDSL modems Refer to ITU-T G.997.1 chapter 7.5.2.8 Independent whether retransmission is used or not in a given transmit direction: - In L0 state, this parameter reports the Net Data Rate (as specified in G.992.3, G.992.5 or G.993.2) at which the bearer channel is operating. - In L2 state, the parameter contains the Net Data Rate (as specified in G.992.3, G.992.5 or G.993.2) in the previous L0 state.

* ltq-vdsl-app: add ubus support to get metricsAndre Heider2021-02-081-0/+807
Add a 'dsl' ubus object with a 'metrics' function to replace the expensive shell parsing done by /etc/init.d/dsl_control [dsl|luci]stat. All metrics are gathered by using syscalls. An additional thread is started to handle ubus events. $ time /etc/init.d/dsl_control dslstat real 0m 2.66s user 0m 0.90s sys 0m 1.76s $ time ubus call dsl metrics real 0m 0.02s user 0m 0.00s sys 0m 0.01s Example output: { "api_version": "4.17.18.6", "firmware_version": "5.8.1.5.0.7", "chipset": "Lantiq-VRX200", "driver_version": "1.5.17.6", "state": "Showtime with TC-Layer sync", "up": true, "uptime": 3891, "atu_c": { "vendor_id": [ 181, 0, 66, 68, 67, 77, 178, 26 ], "vendor": "Broadcom 178.26", "system_vendor_id": [ 181, 0, 66, 68, 67, 77, 0, 0 ], "system_vendor": "Broadcom", "version": [ 49, 57, 46, 48, 46, 51, 53, 46, 50, 32, 86, 69, 95, 49, 49, 95 ], "serial": [ 65, 65, 49, 52, 52, 54, 70, 69, 48, 90, 87, 45, 48, 56, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 ] }, "power_state": "L0 - Synchronized", "xtse": [ 0, 0, 0, 0, 0, 0, 0, 2 ], "annex": "B", "standard": "G.993.2", "profile": "17a", "mode": "G.993.2 (VDSL2, Profile 17a, with down- and upstream vectoring)", "upstream": { "vector": true, "trellis": true, "bitswap": true, "retx": true, "virtual_noise": false, "interleave_delay": 0, "data_rate": 31999000, "latn": 8.500000, "satn": 8.400000, "snr": 12.700000, "actps": -90.100000, "actatp": 13.400000, "attndr": 37180000 }, "downstream": { "vector": true, "trellis": true, "bitswap": true, "retx": true, "virtual_noise": false, "interleave_delay": 140, "data_rate": 89998000, "latn": 9.500000, "satn": 9.600000, "snr": 13.300000, "actps": -90.100000, "actatp": -1.600000, "attndr": 116315372 }, "errors": { "near": { "es": 1, "ses": 0, "loss": 3, "uas": 424, "lofs": 0, "fecs": 0, "hec": 0, "ibe": 0, "crc_p": 0, "crcp_p": 0, "cv_p": 0, "cvp_p": 0, "rx_corrupted": 27740, "rx_uncorrected_protected": 27010, "rx_retransmitted": 0, "rx_corrected": 730, "tx_retransmitted": 16222 }, "far": { "es": 242, "ses": 71, "loss": 0, "uas": 424, "lofs": 0, "fecs": 22687, "hec": 0, "ibe": 0, "crc_p": 0, "crcp_p": 0, "cv_p": 0, "cvp_p": 0, "rx_corrupted": 1383552, "rx_uncorrected_protected": 1220215, "rx_retransmitted": 0, "rx_corrected": 163337, "tx_retransmitted": 1574051 } } } Signed-off-by: Andre Heider <a.heider@gmail.com> Tested-by: Martin Schiller <ms@dev.tdt.de>
