4Subject: [PATCH 2/2] fix(sdl): handle both LV_IMAGE_SRC_FILE and
5 LV_IMAGE_SRC_VARIABLE
6
7The SDL image draw code currently assumes that the image source is a
8filename and attempts to open that filename. This is not necessarily
9the case, e.g. the lv_demo_fb uses encoded images which are of type
10LV_IMAGE_SRC_VARIABLE and instead of filename, come with a buffer of
11pixels. Handle the later using SDL_CreateRGBSurfaceFrom().

4Subject: [PATCH 3/6] Make fbdev device node runtime configurable via
5 environment variable
6
7Test whether $LV_VIDEO_CARD environment variable is non-NULL and in
8case it is, use it as the video card file in lv_linux_fbdev_set_file().
9Otherwise fall back to /dev/fb0, i.e. the current behavior. This way,
10it is possible to test LVGL on systems with multiple fbdev devices.

5
6Add missing version suffix to shared libraries. Currently the filename of
7generated shared libraries is only liblvgl.so, which prevents coexistence
8of different versions of LVGL on the same system. Set VERSION and SOVERSION
9to make cmake add the version suffix to generated shared libraries. That
10changes the filename to liblvgl.so.9.0.0 and includes symlink with major
11ABI version, i.e. liblvgl.so.9 .
