Message-Id: <20250706-msm-no-iommu-v1-0-9e8274b30c33@oss.qualcomm.com> Date: Sun, 06 Jul 2025 13:50:35 +0300 From: Dmitry Baryshkov <dmitry.baryshkov@....qualcomm.com> To: Rob Clark <robin.clark@....qualcomm.com>, Dmitry Baryshkov <lumag@...nel.org>, Abhinav Kumar <abhinav.kumar@...ux.dev>, Jessica Zhang <jessica.zhang@....qualcomm.com>, Sean Paul <sean@...rly.run>, Marijn Suijten <marijn.suijten@...ainline.org>, David Airlie <airlied@...il.com>, Simona Vetter <simona@...ll.ch>, Antonino Maniscalco <antomani103@...il.com> Cc: linux-arm-msm@...r.kernel.org, dri-devel@...ts.freedesktop.org, freedreno@...ts.freedesktop.org, linux-kernel@...r.kernel.org Subject: [PATCH 0/3] drm/msm: drm_gpuvm leftovers After switching to drm_gpuvm, the IOMMU becomes a requirement even for KMS-only devices (e.g. allocating a buffer for DSI commands now also requires the IOMMU / GPUVM). Disallow non-IOMMU configurations. Note: MDP4 patches were compile-tested only. Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@....qualcomm.com> --- Dmitry Baryshkov (3): drm/msm/mdp4: stop supporting no-IOMMU configuration drm/msm: stop supporting no-IOMMU configuration drm/msm/mdp4: use msm_kms_init_vm() instead of duplicating it drivers/gpu/drm/msm/disp/mdp4/mdp4_kms.c | 27 +++++---------------------- drivers/gpu/drm/msm/msm_kms.c | 4 ++-- 2 files changed, 7 insertions(+), 24 deletions(-) --- base-commit: 8290d37ad2b087bbcfe65fa5bcaf260e184b250a change-id: 20250706-msm-no-iommu-c15212a0e7ac Best regards, -- With best wishes Dmitry
