Changed the bug label. This is not seen in pull-request CI, but rather only in the Intel daily test.

This is not seen in pull-request CI, but rather only in the Intel daily test.

It's both, PR example: https://sof-ci.01.org/softestpr/PR1236/build782/devicetest/index.html

This is clearly a recent regression, happened some time early in October. More info in (unrelated) #9587 (comment)

(1)
The problem is not a recent regression. I tried to bisect to find the bad commit and I went down to commit merged on Aug 5 and still can reproduce the problem. It just more harder to reproduce, I run 100 test iteration instead of 50, sometimes it succeeded even with 100 iterations and I run the test again and eventually it fails. Seems on recent builds it is easier to reproduce the problem but the problem exists with builds much older then October builds.

(2)
When the problem happens log shows something like this:

[ 1198.015848] <dbg> dai_comp: dai_common_config_prepare: comp:4 0x40004 channel = 0
...
[ 1198.015883] <err> dai_comp: dai_common_config_prepare: comp:4 0x40004 dma_request_channel() failed

Gateway 0x40004 requests HDA link DMA channel 0. However, that same channel is still in use by gateway 0x4:

[ 1193.396756] <dbg> dai_comp: dai_common_config_prepare: comp:0 0x4 channel = 0

From the same log on all older successful iterations of test gateway 0x40004 was always requesting DMA channel 3:

[ 1193.418940] <dbg> dai_comp: dai_common_config_prepare: comp:4 0x40004 channel = 3

On LNL DMA channel is specified in blob that comes from driver. I added more logs to copier_alh_assign_dai_index(). What it shows that on successful iterations of test gateway 0x40004 was assigned stream_id == 4, dai_index ==4 and DMA channel 3. On failed iteration: stream_id == 1, dai_index == 1, DMA channel == 0.

That data comes in blob from driver. There is a small possibility blob is somehow corrupted on DSP side, however, I would suggest to look on driver side is there a possibility wrong stread_id is assigned to blob. Maybe it is some bug in logic selecting stream_id on driver side?

Just in case, I see gateway 0x4 is actually a "multi-gateway": it is a single copier using two gateways internally. Those gateways use HDA link channels 0 and 1. Multi-gateway case is kind of unusual, maybe driver has a bug related to properly handling stream_id when multi-gateways are in use.

@ranj063 @bardliao @ujfalusi Can you take look at above from driver perspective, multi-gatewa ysage with 0x4 expected?

[kv2019i]

[ 1198.015848] dai_comp: dai_common_config_prepare: comp:4 0x40004 channel = 0
...
[ 1198.015883] dai_comp: dai_common_config_prepare: comp:4 0x40004 dma_request_channel() failed

... based on this, could be related to #9584

[ujfalusi]

I think the issue might be caused by / related to (kernel commit) 0247199fa8eb ("ASoC: SOF: ipc4-topology: Do not set ALH node_id for aggregated DAIs")

In sof_ipc4_dai_config() if blob->alh_cfg.device_count > 1 then we don't set the copier_data->gtw_cfg.node_id.
But in sof_ipc4_prepare_copier_module() the list_for_each_entry(w, &sdev->widget_list, list) loop for ALH will try to use it:

        node_type = SOF_IPC4_GET_NODE_TYPE(alh_data->gtw_cfg.node_id);
        blob->alh_cfg.mapping[i].device = SOF_IPC4_NODE_TYPE(node_type);

and after that loop we set the node_id in case of blob->alh_cfg.device_count > 1
