From dd5abc7834ffae1ca6c399583353e00886817181 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Fri, 22 Jan 2021 10:13:53 +0900 Subject: ASoC: soc-pcm: fixup snd_pcm_limit_hw_rates() timing soc-pcm has snd_pcm_limit_hw_rates() which determine rate_min/rate_max. It updates runtime->hw.rate_min/max (A) based on hw->rates (B). int snd_pcm_limit_hw_rates(...) { int i; for (...) { (B) if (runtime->hw.rates & (1 << i)) { (A) runtime->hw.rate_min = ... break; } } for (...) { (B) if (runtime->hw.rates & (1 << i)) { (A) runtime->hw.rate_max = ... break; } } return 0; } This means, setup order is 1) set hw->rates 2) call snd_pcm_limit_hw_rates() 3) update hw->rate_min/max soc_pcm_init_runtime_hw() is calling it in good order static void soc_pcm_init_runtime_hw(xxx) { ... 1) hw->rates = snd_pcm_rate_mask_intersect(...); 2) snd_pcm_limit_hw_rates(...); 3) hw->rate_min = max(...); hw->rate_min = max(...); hw->rate_max = min_not_zero(...); hw->rate_max = min_not_zero(...); } But, dpcm_fe_dai_startup() is not. static int dpcm_fe_dai_startup(xxx) { ... 1) 3) dpcm_set_fe_runtime(...); 2) snd_pcm_limit_hw_rates(...); ... } More detail of dpcm_set_fe_runtime() is static void dpcm_set_fe_runtime() { ... for_each_rtd_cpu_dais(rtd, i, cpu_dai) { ... 3) 1) dpcm_init_runtime_hw(...); } ... 3) 1) dpcm_runtime_merge_rate(...); } This patch fixup these into static void dpcm_set_fe_runtime() { ... for_each_rtd_cpu_dais(rtd, i, cpu_dai) { ... 1) 2) 3) dpcm_init_runtime_hw(...); } ... 1) 2) 3) dpcm_runtime_merge_rate(...); } static int dpcm_fe_dai_startup(xxx) { ... dpcm_set_fe_runtime(...); - snd_pcm_limit_hw_rates(...); ... } Link: https://lore.kernel.org/r/87k15l7ewd.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Kuninori Morimoto Link: https://lore.kernel.org/r/8735ytaig8.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown --- sound/soc/soc-pcm.c | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) (limited to 'sound/soc/soc-pcm.c') diff --git a/sound/soc/soc-pcm.c b/sound/soc/soc-pcm.c index 2a625ce0bacb..b79f064887d4 100644 --- a/sound/soc/soc-pcm.c +++ b/sound/soc/soc-pcm.c @@ -1514,6 +1514,10 @@ unwind: static void dpcm_init_runtime_hw(struct snd_pcm_runtime *runtime, struct snd_soc_pcm_stream *stream) { + runtime->hw.rates = stream->rates; + + snd_pcm_limit_hw_rates(runtime); + runtime->hw.rate_min = stream->rate_min; runtime->hw.rate_max = min_not_zero(stream->rate_max, UINT_MAX); runtime->hw.channels_min = stream->channels_min; @@ -1522,7 +1526,6 @@ static void dpcm_init_runtime_hw(struct snd_pcm_runtime *runtime, runtime->hw.formats &= stream->formats; else runtime->hw.formats = stream->formats; - runtime->hw.rates = stream->rates; } static void dpcm_runtime_merge_format(struct snd_pcm_substream *substream, @@ -1648,9 +1651,12 @@ static void dpcm_runtime_merge_rate(struct snd_pcm_substream *substream, pcm = snd_soc_dai_get_pcm_stream(dai, stream); + hw->rates = snd_pcm_rate_mask_intersect(hw->rates, pcm->rates); + + snd_pcm_limit_hw_rates(runtime); + hw->rate_min = max(hw->rate_min, pcm->rate_min); hw->rate_max = min_not_zero(hw->rate_max, pcm->rate_max); - hw->rates = snd_pcm_rate_mask_intersect(hw->rates, pcm->rates); } } } @@ -1738,7 +1744,6 @@ static int dpcm_apply_symmetry(struct snd_pcm_substream *fe_substream, static int dpcm_fe_dai_startup(struct snd_pcm_substream *fe_substream) { struct snd_soc_pcm_runtime *fe = asoc_substream_to_rtd(fe_substream); - struct snd_pcm_runtime *runtime = fe_substream->runtime; int stream = fe_substream->stream, ret = 0; dpcm_set_fe_update_state(fe, stream, SND_SOC_DPCM_UPDATE_FE); @@ -1761,7 +1766,6 @@ static int dpcm_fe_dai_startup(struct snd_pcm_substream *fe_substream) fe->dpcm[stream].state = SND_SOC_DPCM_STATE_OPEN; dpcm_set_fe_runtime(fe_substream); - snd_pcm_limit_hw_rates(runtime); ret = dpcm_apply_symmetry(fe_substream, stream); if (ret < 0) -- cgit v1.2.3
