2019-03-23ASoC: rsnd: fixup rsnd_ssi_master_clk_start() user count checkKuninori Morimoto1-1/+1
[ Upstream commit d9111d36024de07784f2e1ba2ccf70b16035f378 ] commit 4d230d1271064 ("ASoC: rsnd: fixup not to call clk_get/set under non-atomic") added new rsnd_ssi_prepare() and moved rsnd_ssi_master_clk_start() to .prepare. But, ssi user count (= ssi->usrcnt) is incremented at .init (= rsnd_ssi_init()). Because of these timing exchange, ssi->usrcnt check at rsnd_ssi_master_clk_start() should be adjusted. Otherwise, 2nd master clock setup will be no check. This patch fixup this issue.

2018-12-17ASoC: rsnd: fixup clock start checkerKuninori Morimoto1-1/+1
[ Upstream commit 3ee9a76a8c5a10e1bfb04b81db767c6d562ddaf3 ] commit 4d230d12710646 ("ASoC: rsnd: fixup not to call clk_get/set under non-atomic") fixuped clock start timing. But it exchanged clock start checker from ssi->usrcnt to ssi->rate. Current rsnd_ssi_master_clk_start() is called from .prepare, but some player (for example GStreamer) might calls it many times. In such case, the checker might returns error even though it was not error. It should check ssi->usrcnt instead of ssi->rate. This patch fixup it. Without this patch, GStreamer can't switch 48kHz / 44.1kHz.

2018-09-06ASoC: rsnd: don't fallback to PIO mode when -EPROBE_DEFERKuninori Morimoto2-1/+13
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>

2018-09-03ASoC: rsnd: fixup not to call clk_get/set under non-atomicJiada Wang3-6/+28
Clocking operations clk_get/set_rate, are non-atomic, they shouldn't be called in soc_pcm_trigger() which is atomic. Following issue was found due to execution of clk_get_rate() causes sleep in soc_pcm_trigger(), which shouldn't be blocked. We can reproduce this issue by following > enable CONFIG_DEBUG_ATOMIC_SLEEP=y > compile, and boot > mount -t debugfs none /sys/kernel/debug > while true; do cat /sys/kernel/debug/clk/clk_summary > /dev/null; done & > while true; do aplay xxx; done This patch adds support to .prepare callback, and moves non-atomic clocking operations to it. As .prepare is non-atomic, it is always called before trigger_start/trigger_stop.

2018-06-18ASoC: rsnd: SSI parent cares SWSP bitKuninori Morimoto1-11/+21
SSICR has SWSP bit (= Serial WS Polarity) which decides WS pin 1st channel polarity (low or hi). This bit shouldn't exchange after running. Current SSI "parent" doesn't care SSICR, just controls clock only. Because of this behavior, if platform uses SSI0 as playback, SSI1 as capture, and if user starts capture -> playback order, SSI0 SSICR::SWSP bit exchanged 0 -> 1 during captureing, and it makes capture noise. This patch cares SSICR on SSI parent, too.

2018-06-13treewide: devm_kzalloc() -> devm_kcalloc()Kees Cook8-9/+9
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

2018-04-16ASoC: rsnd: Enable IPMMU v2Kuninori Morimoto3-5/+50
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.

SSI had shared counting pointer position method between PIO/DMA mode before. But now DMA mode is using DMAEngine feature to get it. Thus, this counting pointer position method is needed for only PIO mode. We don't need to share code anymore. This patch names PIO related functions as rsnd_ssi_pio_xxx(), and merged/cleanuped each feature.

2017-11-29ASoC: rsnd: TDM 6ch needs 8ch clock for hw refineKuninori Morimoto2-27/+80
Renesas sound needs 8ch clock if TDM 6ch mode, and needs 2ch clock for 6ch or 8ch sound if Multi SSI mode. And these are related to before/after CTU (= Channel Transfer Unit). To calculate these we already has rsnd_runtime_channel_for_ssi() which returns runtime necessary channels. But, it based on runtime->channels which is not yet set when hw refine. We need to use hw_params instead of runtime->xxx when hw refine, and it is not needed after runtime was set. This patch adds new hw_params on rsnd_dai_stream, and it will be removed on rsnd_hw_params(). This is very temporary durty code, but it seems no choice at this point.

Renesas R-Car sound driver should be stopped if unbinded during playbacking/capturing. Otherwise clock open/close counter mismatch happen. One note is that we can't skip from remove function (= return -Exxx) in such case if user used unbind. Because unbind function doesn't check return value from each driver's remove function. This means we must to stop and remove driver in remove function. Now ASoC has snd_soc_disconnect_sync() for this purpose. Let's use it.

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 Morimoto3-17/+21
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] ...
