Use the __drm_atomic_helper_plane_destroy_state() function<br /> to put all the objects that are no longer needed.<br /> <br /> It has been seen after hours of usage of a graphics application or using<br /> kmemleak:<br /> <br /> unreferenced object 0xc63a6580 (size 64):<br /> comm "egt_basic", pid 171, jiffies 4294940784<br /> hex dump (first 32 bytes):<br /> 40 50 34 c5 01 00 00 00 ff ff ff ff 8c 65 3a c6 @P4..........e:.<br /> 8c 65 3a c6 ff ff ff ff 98 65 3a c6 98 65 3a c6 .e:......e:..e:.<br /> backtrace (crc c25aa925):<br /> kmemleak_alloc+0x34/0x3c<br /> __kmalloc_cache_noprof+0x150/0x1a4<br /> drm_atomic_helper_setup_commit+0x1e8/0x7bc<br /> drm_atomic_helper_commit+0x3c/0x15c<br /> drm_atomic_commit+0xc0/0xf4<br /> drm_atomic_helper_set_config+0x84/0xb8<br /> drm_mode_setcrtc+0x32c/0x810<br /> drm_ioctl+0x20c/0x488<br /> sys_ioctl+0x14c/0xc20<br /> ret_fast_syscall+0x0/0x54
