Build on this change and limit the number of PCMs created to number of converters (= maximum number of concurrent display/receivers) when "mst_no_extra_pcms" and "dyn_pcm_no_legacy" quirks are both set. Fix the check in hdmi_find_pcm_slot() to ensure only spec->pcm_used entries are considered in the search. Elsewhere in the driver spec->pcm_used is already checked properly. Doing this avoids following warning at SOF driver probe for multiple machine drivers: [ 112.425297] sof_sdw sof_sdw: hda_dsp_hdmi_build_controls: no PCM in topology for HDMI converter 4 [ 112.425298] sof_sdw sof_sdw: hda_dsp_hdmi_build_controls: no PCM in topology for HDMI converter 5 [ 112.425299] sof_sdw sof_sdw: hda_dsp_hdmi_build_controls: no PCM in topology for HDMI converter 6 Fixes: 13046370c4d1 ("ALSA: hda/hdmi: let new platforms assign the pcm slot dynamically") BugLink: https://github.com/thesofproject/linux/issues/2573 Signed-off-by: Kai Vehmanen Link: https://lore.kernel.org/r/20220414150516.3638283-1-kai.vehmanen@linux.intel.com Signed-off-by: Takashi Iwai Signed-off-by: Sasha Levin --- sound/pci/hda/patch_hdmi.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/sound/pci/hda/patch_hdmi.c b/sound/pci/hda/patch_hdmi.c index cf4f277dccdd..26637a695979 100644 --- a/sound/pci/hda/patch_hdmi.c +++ b/sound/pci/hda/patch_hdmi.c @@ -1387,7 +1387,7 @@ static int hdmi_find_pcm_slot(struct hdmi_spec *spec, last_try: /* the last try; check the empty slots in pins */ - for (i = 0; i < spec->num_nids; i++) { + for (i = 0; i < spec->pcm_used; i++) { if (!test_bit(i, &spec->pcm_bitmap)) return i; } @@ -2263,7 +2263,9 @@ static int generic_hdmi_build_pcms(struct hda_codec *codec) * dev_num is the device entry number in a pin */ - if (codec->mst_no_extra_pcms) + if (spec->dyn_pcm_no_legacy && codec->mst_no_extra_pcms) + pcm_num = spec->num_cvts; + else if (codec->mst_no_extra_pcms) pcm_num = spec->num_nids; else pcm_num = spec->num_nids + spec->dev_num - 1;
