2021-11-12ASoC: rsnd: fixup DMAEngine APIKuninori Morimoto1-1/+1
commit d5bb69dc54ec1 ("ASoC: sh: rcar: dma: : use proper DMAENGINE API for termination") updated DMAEngine API _all() to _sync(), but it should be _async(). _all() and _async() are almost same, the difference is only return error code. _sync() will call dmaengine_synchronize() and will be kernel panic. This patch is needed for v5.15 or later.

2021-08-20ASoC: rsnd: adg: clearly handle clock error / NULL caseKuninori Morimoto1-6/+6
This driver is assuming that all adg->clk[i] is not NULL. Because of this prerequisites, for_each_rsnd_clk() is possible to work for all clk without checking NULL. In other words, all adg->clk[i] should not NULL. Some SoC might doesn't have clk_a/b/c/i. devm_clk_get() returns error in such case. This driver calls rsnd_adg_null_clk_get() and use null_clk instead of NULL in such cases. But devm_clk_get() might returns NULL even though such clocks exist, but it doesn't mean error (user deliberately chose to disable the feature). NULL clk itself is not error from clk point of view, but is error from this driver point of view because it is not assuming such case. But current code is using IS_ERR() which doesn't care NULL. This driver uses IS_ERR_OR_NULL() instead of IS_ERR() for clk check. And it uses ERR_CAST() to clarify null_clk error. One concern here is that it unconditionally uses null_clk if clk_a/b/c/i was error. It is correct if it doesn't exist, but is not correct if it returns error even though it exist. It needs to check "clock-names" from DT before calling devm_clk_get() to handling such case. But let's assume it is overkill so far.

In general Renesas SoC's SSI/SRC are all enabled, but some SoC is not. H2 E2 SRC0 <= SRC1 SRC1 SRC2 SRC2 ... ... Renesas Sound driver is assuming that *all* modules are enabled, and thus it is using *data array* to access each modules. Because of it, we have been using "status = disabled" at DT, and using *full size* array but avoiding disabled module. ex) rcar_sound,src { src-0 { => status = "disabled"; }; src1: src-1 { ... }; ... But R-Car D3 have many disabled modules (It has SSI3/SSI4, SRC5/SRC6), and Renesas SoC maintainer don't want above style on DT. ex) rcar_sound,src { => src0: src-0 { status = "disabled"; }; => src1: src-1 { status = "disabled"; }; => src2: src-2 { status = "disabled"; }; => src3: src-3 { status = "disabled"; }; => src4: src-4 { status = "disabled"; }; src5: src-5 { ... }; src6: src-6 { ... }; }; rcar_sound,ssi { => ssi0: ssi-0 { status = "disabled"; }; => ssi1: ssi-1 { status = "disabled"; }; => ssi2: ssi-2 { status = "disabled"; }; ssi3: ssi-3 { ... }; ssi4: ssi-4 { ... }; }; To adjust it, it needs to care about related for_each_child_of_node() loop on rsnd driver, and it is used from... > grep -l for_each_child_of_node sound/soc/sh/rcar/* sound/soc/sh/rcar/core.c sound/soc/sh/rcar/ctu.c sound/soc/sh/rcar/dma.c sound/soc/sh/rcar/dvc.c sound/soc/sh/rcar/mix.c sound/soc/sh/rcar/src.c sound/soc/sh/rcar/ssi.c sound/soc/sh/rcar/ssiu.c This patch adjust to this situation.

2021-05-27ASoC: rsnd: protect mod->statusKuninori Morimoto2-26/+36
Renesas Sound uses many modules (SSI/SSIU/SRC/CTU/MIX/DVC/DMA), and supports complex connections/path. Thus each modules needs to save its status to correctly control it. This status is updated when by .trigger, and .hw_params/.hw_free. Renesas Sound is protecting modules by using lock when .trigger, but it was not enough to protecting each modules "status" if it was used from many paths. 1) .hw_params/.hw_free update status 2) another doesn't update status, but overwrites by same value This patch do 1) protects .hw_params/.hw_free by lock 2) do nothing if no status update Without this patch, protected mod->status (= .trigger) might be overwrote by non protected mod->status (= .hw_params / .hw_free), and in such case, CTU/MIX/DVC/SSIU/SSI which are used from many paths might get damage. If above issue happens, Renesas Sound will be hung (= silence) and never be recoverd. I could reproduce this issue by continue playing very short sound with loop very long term (3-4 hours) through 2 inputs (= MIXer). For updating rsnd_status_update(), this patch removes rsnd_dai_call() debug message. Because we already have debugfs support, and is not good match to new code. Reported-by: Linh Phung T.

commit 66c705d07d784 ("SoC: rsnd: add interrupt support for SSI BUSIF buffer") adds __rsnd_ssi_interrupt() checks for BUSIF status, but is using "break" at for loop.

2021-04-14ASoC: rsnd: call rsnd_ssi_master_clk_start() from rsnd_ssi_init()Kuninori Morimoto1-9/+5
Current rsnd needs to call .prepare (P) for clock settings, .trigger for playback start (S) and stop (E). It should be called as below from SSI point of view. P -> S -> E -> P -> S -> E -> ... But, if you used MIXer, below case might happen (2) 1: P -> S ---> E -> ... 2: P ----> S -> ... (1) (3) P(1) setups clock, but E(2) resets it. and starts playback (3). In such case, it will reports "SSI parent/child should use same rate". rsnd_ssi_master_clk_start() which is the main function at (P) was called from rsnd_ssi_init() (= S) before, but was moved by below patch to rsnd_soc_dai_prepare() (= P) to avoid using clk_get_rate() which shouldn't be used under atomic context. commit 4d230d1271064 ("ASoC: rsnd: fixup not to call clk_get/set under non-atomic") Because of above patch, rsnd_ssi_master_clk_start() is now called at (P) which is for non atomic context. But (P) is assuming that spin lock is *not* used. One issue now is rsnd_ssi_master_clk_start() is checking ssi->xxx which should be protected by spin lock. After above patch, adg.c had below patch for other reasons. commit 06e8f5c842f2d ("ASoC: rsnd: don't call clk_get_rate() under atomic context") clk_get_rate() is used at probe() timing by this patch. In other words, rsnd_ssi_master_clk_start() is no longer using clk_get_rate() any more. This means we can call it from rsnd_ssi_init() (= S) again which is protected by spin lock. This patch re-move it to under spin lock, and solves 1. checking ssi->xxx without spin lock issue. 2. clk setting / device start / device stop race condition. Reported-by: Linh Phung T.

2021-03-16ASoC: rsnd: core: Check convert rate in rsnd_hw_paramsMikhail Durnev1-1/+68
snd_pcm_hw_params_set_rate_near can return incorrect sample rate in some cases, e.g. when the backend output rate is set to some value higher than 48000 Hz and the input rate is 8000 Hz. So passing the value returned by snd_pcm_hw_params_set_rate_near to snd_pcm_hw_params will result in "FSO/FSI ratio error" and playing no audio at all while the userland is not properly notified about the issue. If SRC is unable to convert the requested sample rate to the sample rate the backend is using, then the requested sample rate should be adjusted in rsnd_hw_params. The userland will be notified about that change in the returned hw_params structure.
