No, there isn't. whandle.stride is pipe_resource's stride and is for GPU access. pipe_transfer.stride can be different and is for CPU access. --=20 You are receiving this mail because: You are the assignee for the bug.= --15554449280.fE40D541.16992 Date: Tue, 16 Apr 2019 20:02:08 +0000 MIME-Version: 1.0 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://bugs.freedesktop.org/ Auto-Submitted: auto-generated

No, there isn't. whandle.stride is pipe_resource's stride and is for GPU
access. pipe_transfer.stride can be different and is for CPU access.
