Subject: [PATCH char-misc-next 0/4] mei: csc: add and enable polling option
Date: Mon, 31 Aug 2026 14:38:30 +0300 [thread overview]
Message-ID: <20260831-cri_polling-v1-0-d927315e6598@intel.com> (raw)
Add polling option for CSC hardware with not working interrupt line.
Enable it by default as current hardware is broken.
Fix common mei-me polling code to avoid stalls and access to
powered down hardware.
