2018-07-24audio/hda: Fix migrationDr. David Alan Gilbert
Fix outgoing migration which was crashing in vmstate_hda_audio_stream_buf_needed, I think the problem is that we have room for upto 4 streams in the array but only use 2, when we come to try and save the state of the unused streams we hit st->state == NULL.

2018-06-25audio/hda: detect output buffer overrunsGerd Hoffmann
If some event caused some larger playback hickup the fine-grained timer adjust isn't able to recover. Use a buffer overruns as indicator for that. Reset timer adjust logic in case we detected one. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20180622111200.30561-5-kraxel@redhat.com
2018-06-25audio/hda: tweak timer adjust logicGerd Hoffmann
We have some jitter in the audio timer call frequency and buffer sizes. So it is rather pointless trying to be very exact, effect is a constant up+down adjustment. So adjust only in case we are off too much. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Message-id: 20180622111200.30561-4-kraxel@redhat.com

2018-06-25audio/hda: create millisecond timers that handle IOGerd Hoffmann
Currently, the HDA device tries to sync itself with the QEMU audio backend by waiting for the guest driver to handle buffer completion interrupts. This causes the backend to often read too much data from the device, as well as running out of data whenever the guest takes too long to handle the interrupt. According to the HDA specification, the guest is also not required to use interrupts, but can also sync itself by polling the LPIB registers. This patch will introduce high frequency (1000Hz) timers that interface with the device and allow for much smoother emulation of the LPIB registers. Since the timing is now provided by these timers, the need to wait for buffer completion interrupts also ceases.

After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.
