Subject: [PATCH 0/2] Fix for CVS getting stuck on fast subsequent capture
Date: Mon, 12 Oct 2026 22:25:23 +0300 [thread overview]
Message-ID: <cover.1791831649.git.antti.laakso@linux.intel.com> (raw)
The CVS may get stuck if sensor stops streaming mid-frame. To recover
CVS the CSI ownership need to be transferred to CVS and back to host.
This is done in CVS runtime pm suspend/resume, but it is prone to timing
related errors.
Fix is to change CSI link ownership in stream enable/disable.
The problem is reproduced and fix tested on Dell Pro13.
