[PATCH] drm/vc4: Use 16bpp by default for the fbdev buffer

2019-03-06 Thread Maxime Ripard
The preferred bpp for the fbdev emulation buffer has been 32 so far, which means that by default we will allocate an 8MB buffer with a 1920x1080 resolution. Worse this memory will be allocated from the CMA pool, and will never be freed even if we don't use the fbdev emulation. Therefore, reducing
