From a10fbfcaaa531e67229ad6d43eea0ad8ec3e75f5 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Tue, 19 Mar 2019 17:13:09 +0100 Subject: libcamera: ipu3: Connect viewfinder's BufferReady signal The viewfinder and main output require identical logic for buffer and request completion. Connect the viewfinder bufferReady signal to the slot and handle requests for both main output and viewfinder there. Update the slot logic to complete the request only when the last buffer has completed, and make sure to complete requests in the same order they have been queued to the pipeline handler.
