2018-09-06ASoC: rsnd: don't fallback to PIO mode when -EPROBE_DEFERKuninori Morimoto1-0/+4
Current rsnd driver will fallback to PIO mode if it can't get DMA handler. But, DMA might return -EPROBE_DEFER when probe timing. This driver always fallback to PIO mode especially from commit ac6bbf0cdf4206c ("iommu: Remove IOMMU_OF_DECLARE") because of this reason. The DMA driver will be probed later, but sound driver might be probed as PIO mode in such case. This patch fixup this issue. Then, -EPROBE_DEFER is not error. Thus, let's don't indicate error message in such case. And it needs to call rsnd_adg_remove() individually if probe failed, because it registers clk which should be unregister. Maybe PIO fallback feature itself is not needed, but let's keep it so far. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2018-04-16ASoC: rsnd: Enable IPMMU v2Kuninori Morimoto1-0/+7
commit 4821d914fe747 ("ASoC: rsnd: use dma_sync_single_for_xxx() for IOMMU") (= v1) which have been already reverted had supported IPMMU support on rsnd driver. Because memory allocating timing and DMAEngine access timing were different, it used continuous memory and called dma map function by itself. OTOH, it is using DMA descriptor mode (= DMA cyclic mode), thus, there was timing conflict between DMA sync/unsync and DMA transfer starting, and it maked sound noise. This patch supports IPMMU with coherent memory, and, it uses Audio DMAC dev for allocating memory by snd_pcm_lib_preallocate_pages_for_all() to indicate memory area to IPMMU. One note is that Playback/Capture need each paired Audio DMAC dev. Because of this, we need to keep each paired Audio DMAC dev when probing, and use it when allocating each memory for IPMMU.

2018-04-16ASoC: rsnd: add RSND_GEN3 for R-Car Gen3Kuninori Morimoto1-2/+2
rsnd driver is supporting Gen3. The difference between Gen1 and Gen2 were very big, but, between Gen2 and Gen3 are not so much. Thus, it is assuming Gen2 and Gen3 have compatible, therefore, there is no RSND_GEN3 and rsnd_is_gen3() macro. But in the future, it will need Gen2 and Gen3 different operation, and for Gen4. This patch adds missing RSND_GEN3 and rsnd_is_gen3() macro.

2017-11-16ASoC: rcar: revert IOMMU support so farKuninori Morimoto1-80/+6
commit 4821d914fe74 ("ASoC: rsnd: use dma_sync_single_for_xxx() for IOMMU") had supported IOMMU, but it breaks normal sound "recorde" and both PulseAudio's "playback/recorde". The sound will be noisy. That commit was using dma_sync_single_for_xxx(), and driver should make sure memory is protected during CPU or Device are using it. But if driver returns current "residue" data size correctly on pointer function, player/recorder will access to protected memory. IOMMU feature should be supported, but I don't know how to handle it without memory cache problem at this point. Thus, this patch simply revert it to avoid current noisy sound.

2017-11-01ASoC: rsnd: remove NULL check from rsnd_mod_name()/rsnd_mod_id()Kuninori Morimoto1-6/+18
Current rsnd driver has rsnd_mod_id() which returns mod ID, and it returns -1 if mod was NULL. In the same time, this driver has rsnd_mod_name() which returns mod name, and it returns "unknown" if mod or mod->ops was NULL. Basically these "mod" never be NULL, but the reason why rsnd driver has such behavior is that DMA path finder is assuming memory as "mod == NULL". Thus, current DMA path debug code prints like below. Here "unknown[-1]" means it was memory. ... rcar_sound ec500000.sound: unknown[-1] from rcar_sound ec500000.sound: src[0] to rcar_sound ec500000.sound: ctu[2] rcar_sound ec500000.sound: mix[0] rcar_sound ec500000.sound: dvc[0] rcar_sound ec500000.sound: ssi[0] rcar_sound ec500000.sound: audmac[0] unknown[-1] -> src[0] ... 1st issue is that it is confusable for user. 2nd issue is rsnd driver has something like below code. mask |= 1 << rsnd_mod_id(mod); Because of this kind of code, some statically code checker will reports "Shifting by a negative value is undefined behaviour". But this "mod" never be NULL, thus negative shift never happen. To avoid these issues, this patch adds new dummy "mem" to indicate memory, and use it to indicate debug information, and, remove unneeded "NULL mod" behavior from rsnd_mod_id() and rsnd_mod_name(). The debug information will be like below by this patch ... rcar_sound ec500000.sound: mem[0] from rcar_sound ec500000.sound: src[0] to rcar_sound ec500000.sound: ctu[2] rcar_sound ec500000.sound: mix[0] rcar_sound ec500000.sound: dvc[0] rcar_sound ec500000.sound: ssi[0] rcar_sound ec500000.sound: audmac[0] mem[0] -> src[0] ...

2017-09-21ASoC: rsnd: add rsnd_dma_alloc()Kuninori Morimoto1-27/+33
R-Car sound DMA will be used from SSI/SRC. dma.c doesn't alloc DMA handler in .probe timing, because we don't know what kind of DMA transfer will be used then. Thus, SSI/SRC have *rsnd_mod for DMA. rsnd_dma_attach() will allocate it and attach it to system. It will be PIO mode if it can't alloc DMA handler. In case of MIX is used, rsnd_dma_attach() will be called twice from SSI. To avoid duplicate allocation, current rsnd_dma_attach() is checking allocated DMA handler. This DMA related operation is a little bit difficult to understand. This patch adds new rsnd_dma_alloc() and separates allocation and attach for readable code.

2016-11-22ASoC: rsnd: Request/Release DMA channel each timeKuninori Morimoto1-77/+107
Current Renesas Sound driver requests DMA channel when .probe timing, and release it when .remove timing. And use DMA on .start/.stop But, Audio DMAC power ON was handled when request timing (= .probe), and power OFF was when release timing (= .remove). This means Audio DMAC power is always ON during driver was enabled. The best choice to solve this issue is that DMAEngine side handle this. But current DMAEngine API design can't solve atmic/non-atmic context issue for power ON/OFF. So next better choice is sound driver request/release DMA channel each time.

SSI will be used as normal SSI or as clock parent SSI. Therefor, rsnd driver wants to control SSI and parent SSI separately. Otherwise it can't use Playback/Capture in the same time. And it has been done by c2dc47d5cf("ASoC: rsnd: rsnd_dai_stream has each mod's status insted of rsnd_mod") before. OTOH, rsnd driver doesn't want to control CTU/MUX/DVC/SSIU/SSI in separately.

2015-07-17ASoC: rsnd: update Audio DMA path search methodKuninori Morimoto1-35/+53
Current rsnd driver is assuming Audio DMAC / Audio DMAC peri peri are used from SSI/SSIU/SRC/DVC. But we will add CTU/MIX to this driver. Then, current DMA path searching method is not understandable, and good enough for this purpose. This patch update DMA path search method, more simply.

2015-07-17ASoC: rsnd: dma: add DMA name on .opsKuninori Morimoto1-1/+11
Current rsnd driver is using Audio DMAC (via DMAEngine) and Audio DMAC peri peri (via original method), and usage of these DMAC are different. Indicates its naming is useful for debugging.

2015-06-16ASoC: rsnd: don't call snd_pcm_period_elapsed() under spin lockKuninori Morimoto1-1/+10
'a9e1ac1a9e4585b5("ASoC: rsnd: spin lock for interrupt handler")' added spin lock under interrupt handler to solve HW restart issue. OTOH, current rsnd driver calls snd_pcm_period_elapsed() from rsnd_dai_pointer_update(). but, it will be called under spin lock if SSI was PIO mode. If it was called under spin lock, it will call snd_pcm_update_state() -> snd_pcm_drain_done(). Then, it calls rsnd_soc_dai_trigger() and will be dead-lock. This patch doesn't call rsnd_dai_pointer_update() under spin lock Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Tested-by: Keita Kobayashi <keita.kobayashi.ym@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

2015-03-11ASoC: rsnd: recover PIO mode for new dma interfaceKuninori Morimoto1-1/+18
Renesas sound driver needs 1st/2nd DMA interface, and 1st DMA is using DMAEngine, and 2nd is using local method now. 2nd DMA had been DMAEngine, but it was moved to local method by previous patchset. But then, it lost PIO mode fallback when probe. this patch recovers it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
