Subject: media: venus: Set buffer to FW based on FW min count requirement. Author: Dikshita Agarwal <[email protected]> Date: Tue Aug 10 11:47:55 2021 +0200 - Get the min buffer count required by FW from source event change and use the same value to decide actual buffer count and for buffer size calculation. - Setup DPB and OPB buffers after session continue incase of reconfig.
