Hello, since our SoC doesn't support hardware cursor, i want to enable SW cursor with xf86-video-armsoc driver. So i set the cursor API type to HWCURSOR_API_NONE in my driver. list as bellow. +struct drmmode_interface hisi_interface = { + 1 /* use_page_flip_events */, + 1 /* use_early_display */, + CURSORW /* cursor width */, + CURSORH /* cursor_height */, + CURSORPAD /* cursor padding */, + HWCURSOR_API_NONE /* cursor_api */, + NULL /* init_plane_for_cursor */, + 0 /* vblank_query_supported */, + create_custom_gem /* create_custom_gem */, +};

But when i run startx the X crash with log pasted bellow: And if i set the cursor API type to HWCURSOR_API_STANDARD, X can start up , but without cursor display.

Does anybody know what's wrong it is? And how to enable SW cursor with xf86-video-armsoc driver?
