msm: vidc: Use the future w/h for calculating DCVS load if in reconfig (e91c8504) · Commits · e / devices / android_kernel_xiaomi_markw

If we're in the middle of a reconfig and *_dcvs_supported() is called, it return false. As a result, we end up under-allocating buffers during the reconfig event which causes DCVS to scale poorly post-reconfig. So, when we query to see if the session is supported by DCVS, consider the new W/H if we're in middle of a reconfig. Change-Id: I6dd1c94f4a5c7b240027c0efb56694b3f555592e Signed-off-by:
