It appears to be calling drm_add_edid_modes, which indirectly calling ito either do_detailed_mode or drm_mode_duplicate. This has caused me to run out of memory a handful of times, which could only be resolved by rebooting. I only experienced this after upgrading to 5.9.1, and it looks like commit b24bdc37d03a0478189e20a50286092840f414fa added the call to drm_add_edid_modes in amdgpu_dm_update_connector_after_detect. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
