We have a workaround in place to address a known issue with host DMA running into xruns when capture streams are running. But when resuming from Sx, we unconditionally re-enable DMI L1 without taking the workaround into account and this could lead to xruns when a suspended capture stream is restarted. To fix this rename the flag l1_support_enabled to l1_disabled in struct sof_intel_hda_dev to save the L1 disabled status which can be set/cleared when we get/put a stream and use the flag to determine if DMI L1 should enabled or not during the post_fw_run op.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
