From 92411679b1197754e29dd4824de8533f482f7c07 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Wed, 17 Mar 2021 13:31:00 +0100 Subject: libcamera: ipu3: imgu: Update BDS calculation process MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Apply the last three hunks of commit 243d134 ("Fix some bug for some resolutions") from https://github.com/intel/intel-ipu3-pipecfg.git to the BDS calculation procedure. The BDS calculation is now perfomed by scaling both width and height, and repeated by scaling width first.
