Subject: [5.14 regression] "ALSA: core: Add continuous and vmalloc mmap ops" breaks Intel SST audio
Date: Fri, 30 Jul 2021 22:04:00 +0200	[thread overview]
Message-ID: <8d6674da-7d7b-803e-acc9-7de6cb1223fa@redhat.com> (raw)

Hi All;,

As discussed in the "5.14 regression, Intel SST (BYT) audio no longer works" thread,
audio on X86 devices using the Intel SST driver no longer works with 5.14.

After poking at this for a while I've found the culprit:
30b7ba6972d5 ("ALSA: core: Add continuous and vmalloc mmap ops")

If I revert that single commit then everything works fine again with 5.14.

This is with a Fedora 34 userspace using pipewire as audiodaemon

Regards,

Hans
