2017-02-10ALSA: x86: Don't pass SNDRV_PCM_INFO_BATCH flagTakashi Iwai1-4/+2
The PCM engine on LPE audio isn't like a batch-style process any longer, but rather it deals with the standard ring buffer. Remove the BATCH info flag so that PA can handle the buffer in timer-sched mode. Similarly, the DOUBLE flag is also superfluous. Drop both bits. Signed-off-by: Takashi Iwai <tiwai@suse.de>

The pclk is necessary for zx2967 I2S controller. the driver currently doesn't handle it. This is something we need to fix. In turn, the driver supports zx296718's I2S controller.

2017-02-08ALSA: seq: Fix race at creating a queueTakashi Iwai1-13/+20
When a sequencer queue is created in snd_seq_queue_alloc(),it adds the new queue element to the public list before referencing it. Thus the queue might be deleted before the call of snd_seq_queue_use(), and it results in the use-after-free error, as spotted by syzkaller. The fix is to reference the queue object at the right time. Reported-by: Dmitry Vyukov <dvyukov@google.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

At enabling the audio, we modify AUD_CONFIG register bit 0. So far, it does read-modify-write procedure with a special hack for the channel bits due to the silicon bug.

2017-02-07ALSA: x86: Rename had_enable_audio_int() to had_ack_irqs()Takashi Iwai1-14/+7
had_enable_audio_int() came from the LPE audio shell set_caps callback with ENABLE_INT and DISABLE_INT caps. I interpreted as these correspond to enabling / disabling the audio interface, but the actual implementation is only to clear (send ACK) to both BUFFER_DONE and BUFFER_UNDERRUN interrupts unconditionally. And, there is no counterpart, DISABLE_INT, code at all. For avoiding the further misunderstanding, rename the function to the more fitting one, had_ack_irqs(), and drop the calls with enable=false in allover places. There is no functional changes at all. After this patch, there is only one caller at the PCM trigger start. Then it's doubtful whether this call is still really needed or not; I bet it not, but let's stay in the safer side for now and keep it as was. Signed-off-by: Takashi Iwai <tiwai@suse.de>

We have to remove the 'depends on' for SND_SOC_IMX_ES8328 in the same step to avoid a recursive dependency.

2017-02-06ALSA: seq: Don't handle loop timeout at snd_seq_pool_done()Takashi Iwai1-8/+1
snd_seq_pool_done() syncs with closing of all opened threads, but it aborts the wait loop with a timeout, and proceeds to the release resource even if not all threads have been closed. The timeout was 5 seconds, and if you run a crazy stuff, it can exceed easily, and may result in the access of the invalid memory address -- this is what syzkaller detected in a bug report. As a fix, let the code graduate from naiveness, simply remove the loop timeout.

2017-02-06ALSA: x86: Refactor PCM process engineTakashi Iwai3-354/+231
This is again a big rewrite of the driver; now it touches the code to process PCM stream transfers. The most fundamental change is that the driver may support more than four periods. Instead of keeping the same index between both the ring buffer (with the fixed four buffer descriptors) and the PCM buffer periods, we keep difference indices for both (bd_head and pcm_head fields). In addition, when the periods are more than four, we need to track both head and next indices. That is, we now have three indices: bd_head, pcm_head and pcm_filled. Also, the driver works better for periods < 4, too: the remaining BDs out of four are marked as invalid, so that the hardware skips those BDs in its loop. By this flexibility, we can use even ALSA-lib dmix plugin, which requires 16 periods as default. The buffer size could be up to 20bit, so the max buffer size was increased accordingly. However, the buffer pre-allocation is kept as the old value (600kB) as default. The reason is the limited number of BDs: since it doesn't suffice for the useful SG page management that can fit with the usual page allocator like some other drivers, we have to still allocate continuous pages, hence we shouldn't take too big memories there.

The lowlevel register read/write don't have to be careful about the connection state. It should be checked in the caller side instead. By dropping the check, we can simplify the code, and readability. This patch also refacors the functions slightly: namely, - drop the useless always-zero return values - fold the inline functions to the main accessor functions themselves - move the DP audio hack for AUD_CONFIG to the caller side - simplify snd_intelhad_eanble_audio() and drop the unused had_read_modify() Signed-off-by: Takashi Iwai <tiwai@suse.de>
