Subject: [PATCH 7/7] media: venus: Set buffer to FW based on FW min count requirement.
Date: Wed, 19 May 2021 15:06:48 +0530	[thread overview]
Message-ID: <1621417008-6117-8-git-send-email-dikshita@codeaurora.org> (raw)
In-Reply-To: <1621417008-6117-1-git-send-email-dikshita@codeaurora.org>

- 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.
