Patch 1 fixes that in DPU. Patch 2 removes the CTM-only allow_modeset hack in msm_atomic_check(), which patch 1 makes redundant. Changes in v2: - Patch 1: don't set allow_modeset on behalf of userspace (Dmitry) - Patch 2: new, drops the legacy CTM check (Sashiko review) - Link to v1: https://lore.kernel.org/r/20261101095754.33840-1-beat@softbase.tech Beat M.
