From affa8a9fb2f3ed02ab812bf8f991783683fd408d Mon Sep 17 00:00:00 2001 From: Pierre-Eric Pelloux-Prayer Date: Fri, 10 Feb 2023 19:38:33 -0500 Subject: [PATCH] amd/surface: fix base_mip_width of subsampled formats MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit base_mip_width is used in si_compute_copy_image when the SI_IMAGE_ACCESS_BLOCK_FORMAT_AS_UINT flag is used. width = tex->surface.u.gfx9.base_mip_width; This will be incorrect if we don't adjust it. For instance, with a 260x256 image, surf_pitch and base_mip_width are 320 before surf_pitch is updated to be 192. Both need to match, or computing the width from base_mip_width leads to incorrect result.
