From 8806863b0bc4498d098e16dda657ab6f8293d208 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Tue, 6 Oct 2020 17:53:51 +0200 Subject: android: camera_worker: Introduce CameraWorker MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Android camera framework provides for each buffer part of a capture request an acquisition fence the camera HAL is supposed to wait on before using the buffer. As the libcamera HAL runs in the camera service thread, it is not possible to perform a synchronous wait there. Introduce a CameraWorker class that runs an internal thread to wait on a set of fences before queueing a capture request to the libcamera::Camera. Fences completion is handled through a simple poll, similar in implementation to the sync_wait() function provided by libdrm.
