From e5079cf11373e4cc98be8b1072aece429eb2d4d2 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Thu, 23 Aug 2018 10:18:35 -0400 Subject: media: vb2: set reqbufs/create_bufs capabilities Set the capabilities field of v4l2_requestbuffers and v4l2_create_buffers. The various mapping modes were easy, but for signaling the request capability a new 'supports_requests' bitfield was added to videobuf2-core.h (and set in vim2m and vivid). Drivers have to set this bitfield for any queue where requests are supported.
