Subject: [PATCH fro 6.11 0/2] ASoC SOF: ipc4-topology: Fix LinkID handling for ChainDMA
Date: Wed, 24 Jul 2024 11:19:30 +0300	[thread overview]
Message-ID: <20240724081932.24542-1-peter.ujfalusi@linux.intel.com> (raw)

Hi,

A recent patch available in 6.10 [1] uncovered two issues on how the DMA Link ID
is tracked with ChainDMA and can cause under specific conditions [2] to cause a DSP
panic.
The issue is not academic as we have one user report of it:
https://github.com/thesofproject/linux/issues/5116

The patches have been marked for stable backport to made there way to 6.10.

The first patch is fixing a code move patch, for older than 6.9 we would need
different patch to fix the original code, but since the issue is only valid for
6.10, I will do that at a later time.

Mark, can you please schedule these as fixes for 6.11 to get them fast to 6.10?
Thank you.
